TENNANT A85

1. GENERAL

This operating manual belongs to the A85 sweeping vehicle. The purpose of the manual is a safe use and maintenance of the sweeper vehicle and the manual must be available for the operators at all times.

1.1. Purpose of the sweeper

The A85 sweeper vehicle is used for cleaning paved surfaces.

1.2. Operators

In this manual "the operator" refers to: anyone who comes into contact with the A85 sweeper or any of its components under operational circumstances. The organization itself should ensure that every operator is sufficiently qualified to work with this type of vehicle and is capable of taking the stipulations and safety aspects into account. A clear distinction is made between two groups of operators.

- “The driver” is the person who actually operates the vehicle in preparation of or during the production process (sweeping process). The driver must be older than 18 years of age and be aware of his responsibilities.

- ”The technician” is the person who repairs or services the vehicle. The technician must be qualified and trained in technical actions. It is mandatory that the technician has a thorough technical understanding and is able to read technical drawings.

The driver and the technician must be instructed properly before operating or carrying out maintenance on the vehicle. The initial instructions are given by specialists from Tennant N.V. An exception is made if the organization in question already operates several vehicles of the same type, or has sufficient in-house expertise. Tennant N.V. cannot be held responsible for work carried out by an inadequately instructed or unqualified operator.

1.3. Emission data

The hydraulic system of the A85 sweeper vehicle contains hydraulic oil and is powered by a diesel engine, which complies with the Euro-5 legislation The battery of the A85 sweeper vehicle contains battery acid.

1.5. Functional description

The A85 sweeper vehicle is used for cleaning paved surfaces. The refuse in front of the vehicle is collected beneath the vehicle by two brushes. There it is sucked through the suction mouth and transported to the dirt hopper. The suction force in the suction mouth is created by under-pressure in the dirt hopper. There is a fan on the dirt hopper. It forces the air out of the dirt hopper and releases it to the environment through the air extraction duct in the top of the dirt hopper. A labyrinth inside changes the direction of the air stream several times, thereby reducing the noise. The refuse is moistened in the suction mouth so that it precipitates onto the floor of the dirt hopper and cannot be blown out again. The power supply for all the motorized components of the sweeper vehicle is supplied by a hydraulic system. This hydraulic system is in turn powered by the diesel engine. This type of power supply ensures that the diesel engine can maintain a constant engine speed and that all other actions (steering, linear or rotating) are generated by regulating the hydraulic fluid flow. For instance, the driving action, the steering mechanism, the hydraulic cylinders, the sweeping unit and the suction fan are all driven hydraulically. Only the driving speed and fan speed are directly affected by the power and speed of the diesel engine.

» Automatic brake-light system Turned on as soon as the vehicle decelerates. » Sensor mat in driver’s seat Disconnects the brushes and the driving function when the driver is not sitting on the seat. » Reverse alarm Acoustic signal that can be heard when the vehicle reverses. » Audible alarm Acoustic signal that can be heard when the dirt hopper is tipped, lowered or when the rear door opens or closes. » Warning lamp Starts flashing when the dirt hopper starts tipping and continues to flash until the safety support are in place beneath the dirt hopper. When the safety support is removed, the warning light starts flashing again until the dirt hopper is lowered completely. » Hydraulic pressure switch in the tipping cylinders Ensures that above a certain weight the dirt hopper cannot be tipped unless the rear door is open.

TENNANT A85

» Four independent hydraulic pumps To ensure a good functioning of the hydraulic system, it is carried out by four independent pumps. » Over-pressure safeguard on all hydraulic systems » Hose-rupture safeguards The hydraulic tipping cylinders on a standard machine and the lifting cylinders on a high dump machine are fitted with hose-rupture safeguards. » Hydraulic system that ensures that the sweeping unit is blocked when raised The blocking is only removed when the sweeping unit is operated to be lowered. So the sweeping unit cannot be lowered while the vehicle is driving. » Hydraulically-powered steering mechanism The vehicle can still be steered if the diesel engine should break down. The steering mechanism does offer more resistance, but the vehicle can be steered without damaging the system. » Electrical switch on top of the chassis rear (high dump only) The front cylinders always have to extent fully before the rear cylinders may extent when lifting the hopper. An electric switch on top of the chassis (rear) enables is switched when the hopper reaches a certain angle because of the front cylinders. The rear cylinders extend then. There is only one button on the remote control to lift the hopper. » Electrical switch on the rear door (high dump only) The rear door needs to be fully opened before the push plate is enabled to move. An electric switch indicates when the rear door is fully opened and prevents the movement of the push plate. » Security of push plate (high dump only) The push plate moves in when the rear door is closed. This is to prevent the rear door from coming into contact with the push plate. » Electrical switch on top of the chassis rear (high dump only) The rear of the hopper always has to come down first when lowering the hopper. An electrical switch registers when the rear sides of the hooper are at their lowest position, which is when the front of the hopper can be lowered. There is only one button on the remote control to lower the hopper. » Speed limit with raised hopper (high dump only) When the rear of the hopper is not completely lowered the driving speed of the machine is limited to 5 km/hr. An electrical switch registers when the rear of the hopper is in its lowered position and enables the machine to drive the normal speed. » Electrical tilt sensor (high dump only) The hopper can not be lifted when the machine is not parked on a level and solid surface. The electrical tilt sensor disables the lifting of the hopper when the machine is tilted more than 4 degrees either side ways or front to rear.


- 20 -

TENNANT A85

» Electrical proximity switch (high dump only) The push plate movement is disabled when one of the hopper side doors is opened. The proximity switch indicates when the door is opened and disables the push plate movement. » Electrical switch at safety support (high dump only) A high dump machine is equipped with two safety supports. When only the front cylinders are extended and the hopper is tilted, the short safety supports can be put below the hopper. Now it is safe to work below the hopper. The short safety support activates a switch that disables the lowering movement of the hopper.

Never work underneath a hopper when there is still a load in it. Always first completely empty the hopper or ensure yourself that the hopper is empty before lifting the hopper for maintenance purposes. Never work underneath the vehicle when the air system of the front axle is not .fully released of energy/pressure.

2.7.2. Hand-operated provisions

The following safety provisions must be switched on/applied by the operator.

» Starting safeguard The vehicle can only be started when:

- the hand brake has been engaged, - the forward / reverse selector is in neutral (N), and - the driver is seated.

» Foot brake Operates independently of the hydraulic circuit and can be used as an emergency brake in all circumstances. » Lockable main electrical switch » Lockable remote control When locked it cannot be used by others. » Safety supports beneath the dirt hopper The safety supports are extendable when the dirt hopper is fully tipped. » Warning beacons

- two beacons at the front of the machine or optional warning beacon bar - warning beacon bar on rear of machine

» Emergency stops (3)

- One in the cabin on the dashboard - One on the remote control - One in the engine compartment

The emergency stop on the dashboard is fitted with a key so that it can be locked during maintenance or repair work.


- 21 -

TENNANT A85

» Fire extinguisher in cabin The fire extinguisher is located next to the passenger seat inside the cabin. » Camera (optional) On the rear of the vehicle that gives the driver an overview of the back of the vehicle on the monitor/lcd screen in the cabin.

2.8. Emergency situations

An emergency situation occurs when people and/or the vehicle are in acute danger or if an acutely dangerous situation is imminent. If an emergency situation develops, the operator should immediately press the emergency stop. The vehicle will come to a complete standstill immediately and all functions will be switched off. The A85 sweeper vehicle is equipped with three emergency stops:

- one in the cabin on the dashboard - one on the remote control - one in the engine compartment

The emergency stop on the dashboard is fitted with a key so that it can be locked during maintenance or repair work. The remote control can be carried anywhere in or around the vehicle. This ensures that the operator or technician always has an emergency stop at hand in every situation and workplace.

Only when the emergency situation is resolved the emergency stop may be deactivated by turning the switch in the direction indicated by the arrow.

The driver can use the foot brake as an emergency brake while driving. .

3. INSTRUMENTS

Tennant N.V. has devoted a great deal of care to the instruments. With the operator in mind it has been tried to keep the whole conveniently arranged with the various switches in logical positions and easily accessible. The operator will experience many of the symbols, meters and functions as natural and self-explanatory. To prevent mistakes, however, it is important that the operator pays special attention to all explanations and notes in this chapter.

3.14. Tilt sensor (high dump only)

Figure 26: Tilt sensor

The high dump vehicles are equipped with a tilt sensor (see fig. 26). This sensor signals when the machine is parked on a surface with a too large gradient to safely lthe hopper.

ift

The sensor verifies the angle in which the machine is parked in both longitudinal and latitudinal direction in relation to the surface the machine is parked on. The hopper can not be lifted when the machine is not parked inside an angle of 4 degrees in the latitudinal direction and when the machine is not parked inside an angle of 4 degrees in the longitudinal direction. Two LED lights are mounted at the bottom side of the sensor. When the tilt sensor is powered on the red LED will light up indicating the sensor is functioning. When the sensor is tilted by more than 4 degrees, the red LED is switched off whilst the yellow LED will light up. The vehicle is not a on a safe surface to lift the hopper. It is not possible to raise the hopper.

4. VEHICLE OPERATION

Always observe the safety regulations and measures described in section 2.2, 2.3, 2.4 and 2.7.

Before entering traffic, the operator should be sufficiently familiarized with the handling of the sweeper vehicle. This applies particularly to the large steering radius (70°) and the hydraulic drive mechanism. After sufficient practice with the sweeper vehicle the operator may participate in traffic as long as local traffic regulations are observed. Drive carefully at all times, particularly when driving up or down gradients. The driving style should always be adapted to prevailing conditions.

All maneuvers should be stopped if traffic conditions do not allow for their execution.

In connection with safety: o the vehicle must have sufficient lights, and o the warning beacons must be switched on.

4.1. Before driving

Before driving the vehicle the “checkpoints for sweeping” in section 9.1 should be studied.

» The driver seat must be adjusted to the driver’s posture. This is to improve seating

comfort and prevent physical complaints. For the adjustment options please refer to the original operating manual of the chair (supplied).

» The mirrors should be adjusted manually so that the driver can observe the following

from his seat: - The brushes must be visible in the top outside mirrors on both sides of the vehicle. - Via the rear-view mirrors on both sides of the vehicle it must be possible to

observe traffic in the immediate vicinity of the sides and rear of the vehicle.

4.2. Starting the vehicle

The vehicle can only be started when: the driver is seated on the driver's seat, the hand brake has been engaged, and the forward / reverse selector is in neutral (N).

1) Occupy the driver's seat. 2) Place your right foot beside the pedal. 3) Put the forward / reverse selector in neutral (N) (see paragraph 3.2). 4) Apply the parking brake. 5) Check that all functions are deactivated. 6) Turn the ignition key to the 1st position.

The glow plug indicator lamp lights up. 7) Wait until the indicator light is switched off. 8) Then turn the ignition key to the next position and release it as soon as the diesel engine is

running. 9) Rev the engine briefly and then release it.

The dynamo indicator lamp is extinguished and the diesel engine is idling.

4.3. Driving the vehicle

The forward / reverse selector is still in neutral (N). The engine speed is stationary, ±800 revs/min. 1) Check that the sweeping unit is raised (fig. 6, no. 6). 2) Release the hand brake. 3) Select the desired driving direction with the forward/reverse selector (see section 3.2). The operating functions required for driving the vehicle are given below: Driving Pressing down the accelerator pedal (fig. 2, no. 14) will move the vehicle slowly forward, whereby the engine speed of the diesel engine will gradually increase. The speed can be regulated by the extent to which the pedal is pressed. Braking The vehicle’s hydraulic drive system ensures that the vehicle will gradually stop when the accelerator pedal is released. When the foot brake (fig. 2, no. 17) is used, the vehicle immediately brakes forcefully.

The operator must continuously observe the traffic situation and adapt his own situation and actions to it. He must ensure that his attention is not distracted from the traffic.

The mirrors, indicators and lights must be used properly.

4.4. While driving

While driving, the driver must check the following functions of the vehicle and engine regularly to prevent damage: Information display (see section 3.7)

» Check the symbol on the main screen of the information display for the current fuel tank

- There should always be a sufficient amount of diesel in the tank - At a tank level of ± 18 liters, an automatic warning is given.(see section 3.7) - At a tank level of ± 4 liters, an alarm is given (see section 3.7)

» Check the symbol on the main screen of the information display for the current engine temperature

- At an engine temperature of 103 °C, an automatic warning is given (see section 3.7). Avoid any further increase in temperature to prevent damage to the engine.

- At an engine temperature of 107 °C, an alarm is given (see section 3.7). Immediately park the vehicle in a safe place and switch off the diesel engine.

» Check the symbol on the main screen of the information display for the current hydraulic fluid temperature.

- At an engine temperature of 95 �, an automatic warning is given (see section 3.7). Avoid any further increase in temperature to prevent damage to the engine.

- At a hydraulic fluid temperature of 103 �, an alarm is given (see section 3.7). Immediately park the vehicle in a safe place and switch off the diesel engine.

Make sure that when large distances have to be covered the water tank is filled to at least 30% (± 250 L) to ensure sufficient cooling of the hydraulic fluid.

» check the symbol on the main screen of the information display for the battery charge level.

TENNANT A85

4.5. Front axle air suspension

The electronics ensure that the vehicle remains at an equal driving height in a loaded as well as unloaded condition. This is done by means of a height regulator on the front axle. The machine can be raised at the front in order to avoid obstacles. Engage this function by activating switch no. 17 on the middle dashboard, see chapter 3.5. You can use this function in two ways.

1. Hold switch, turn off ignition lock. The vehicle remains in its highest position. 2. Hold switch. As long as the switch is activated, the machine will remain in its highest

position. When the switch is no longer activated, the vehicle will automatically return to its neutral position.

When the vehicle is in its highest position, it may not be driven any faster than 10 km/hour. When it has been standing still for a long period of time, pressure must be built up in the system first, so the machine returns to its neutral situation, before driving with it.

4.6. Switching off the vehicle

The hand brake must always be engaged when the vehicle is switched off. Otherwise the vehicle could start moving of its own accord.

1) Bring the vehicle to a halt:

- First release the accelerator pedal: the vehicle will brake on the engine. - Then push down the brake pedal: the vehicle comes to a complete standstill.

2) Deactivate all engaged functions. 3) Put the forward / reverse selector in neutral (N). 4) Apply the parking brake. 5) Turn the ignition key fully counter-clockwise and remove it from the lock.

5. THE SWEEPING PROCEDURE

Always observe the safety regulations and measures described in section 2.2, 2.4 and 2.7.

Sweeper vehicles are mainly used to clean public roads. The type of refuse usually consists of litter, sand, grit and leaves. The dust that develops during sweeping is settled by continuously spraying it with water. The quality of the sweeping results is largely determined by the adjustments and settings. The adjustment of the brushes depends on various factors (see also section 9.2.2 and 9.2.3). When selecting the driving speed and the brush speed, prevailing conditions should be taken into account. The joystick control of the sweeping unit and the wide steering angle make the vehicle highly maneuverable during the sweeping procedure. When sweeping, always adapt the maneuvering to the prevailing (traffic) conditions. In due course, the operator will become sufficiently experienced to assess the conditions accurately and adapt the sweeping techniques accordingly.

5.1. Sweeping conditions

The settings of vehicle's functions must be based on prevailing conditions. These settings can be adjusted while sweeping, as long as the vehicle and the sweeping procedure remain under control and the operator's attention is not distracted from the traffic.

Adjustment of the sweeping unit and/or 3rd-brush must always be done very carefully. No obstacles or people should be within the danger zone.

Road speed While sweeping, the road speed must be adapted to the prevailing conditions. A maximum speed of 7 km/h is recommended. During sweeping the vehicle is set to a maximum speed of ± 12 km/h forward and ± 8 km/h in reverse at an engine speed of ± 1300 revs/min. The engine speed during sweeping is set by means of the speed regulator “engine speed / fan” at the top of the dashboard (fig. 7). The accelerator pedal therefore only influences the driving speed. The separate reverse pedal (optional) to the left of the steering column (fig. 2, no. 3), can be used to reverse, but only during sweeping. This pedal works independently of the forward / reverse selector. As long as the pedal is depressed, the vehicle reverses.

A sudden switch to reverse at normal sweeping speed could cause hazard to traffic approaching from the rear.

TENNANT A85

Suction power The vehicle's suction power is determined by the diesel engine's speed. Under standard conditions and at engine speeds between 1300-1500 revs/min. wear, fuel consumption and noise levels will be reasonably aligned to the vehicle's performance. Suction mouth Larger pieces of rubbish or large amounts of leaves can be sucked in through the front of the suction mouth which can be opened by means of the joystick (fig. 6, no. 4).

Keep in mind that the suction power is reduced when the mouth is open. If the suction mouth is blocked (by twigs, for example), it can be unblocked by switching off the fan (fig. 6, no. 8), drawing the suction mouth upwards (fig. 6, no. 6) and reversing a small distance to check that the blockage has been removed. Brush speed The brush speed must be adapted to prevailing sweeping conditions, such as: the litter situation, the surface or the road speed.

When the brush speed has to be adjusted, the vehicle must first be brought to a halt. This must be done in order to keep track of the traffic situation.

The brush speed can be regulated by means of the turning knob at the lower right corner in the cabin below the windshield (fig. 2, no. 13). The brush speed can be turned down to 0. Select an appropriate brush speed, but not too high.

High brush speeds lead to increased brush wear and can cause objects, like small stones, to be flung away.

Water pressure The water circuit can be switched between high and low pressure. Under normal conditions low pressure is sufficient to keep the suction mouth clean and prevent accumulation of dust. The higher pressure can be switched on (temporarily) under extreme circumstances or when the suction mouth is blocked.

By means of switch no. 14 on the central cab switchboard (fig. 6) the low or high pressure can be selected.

Sprayer bar

The sprayer bar must be activated in dry conditions to prevent dust from developing (fig. 6, no. 13). Either the right-hand side or both sides can be sprayed. This selection can be made by closing the valve on the sprayer bar (spray only on the right) or opening it (spray on both sides).


- 57 -

TENNANT A85

The cloud maker can be activated (fig. 6, no 28) for an improved dust control around the suction mouth.

cloud maker


- 58 -

Excessive use of water should be avoided during sweeping! The amount of water in the vehicle is limited.

Inspection hatches The dirt hopper has inspection hatches on both sides. These hatches can be opened to put pieces of refuse that are too big for the suction mouth (for instance branches) into the dirt hopper. It is recommended to switch the suction fan off before opening these hatches (fig. 6, no. 8). Sweeping techniques Sweeping techniques can help the driver to: obtain good sweeping results, and carry out the work at an effective speed. Low driving speeds ensure that the maneuverability of the vehicle is used optimally.

Excessive steering maneuvers result in increased tire wear. Inner corners Inner corners can be thoroughly cleaned by using the mobile sweeping unit according (Technique A):

Figure 27: technique A

Moving the sweeping unit can also be used very effectively to: sweep up to and past parked vehicles (Technique B) avoid obstacles, and sweep on the left

9) Switch off the work lights, if necessary.

10) Switch off the vehicle lights, if necessary.

5.4. Use of the manual suction unit (optional)

The A85 can be equipped with a manual suction unit. This can be used to suck up dirt manually. This unit can remain mounted on the vehicle, even if it is not used for a longer period of time. The manual suction unit can be used independently or in combination with the sweeper unit. If the manual suction unit is used in combination with the sweeper unit, the suction force is divided between the manual suction unit and the suction mouth. As a result suction is not very effective. Also, in this situation two operators must work with the machine. When all available suction force is needed for the manual suction unit, in other words when only the manual suction unit is used, the suction mouth has to be closed with the slide behind the cabin on the dirt hopper. For this purpose the dirt hopper has to be tipped to a height of 10 cm (see section 3.11). In this situation a single operator can be used. In contravention to the safety regulations described in section 2.2, this operator is allowed to leave the cabin while the fan and water pump are switched on.

Always ensure sufficient air displacement inside the hose to be able to transport the rubbish to the dirt hopper. Therefore do not hold the hose inside the rubbish, but just above it.

Always point the manual suction unit at the ground and never at persons.

5.5. Using the 3rd brush (optional)

The 3rd brush is located at the front of the vehicle. Adapt the driving and sweeping pattern to this brush attachment.

In order to achieve good sweeping results, the 3rd brush must always be used in combination with the brushes as described in section 5.1. Take the prevailing conditions into account when selecting the brush speed. When sweeping severely polluted areas, it is recommended to use a high brush speed and a low driving speed.

1) Follow the "Start sweeping" procedure (section 5.2), but do not drive off yet.

2) Bring the 3rd brush to the desired position with the joystick (see section 3.9)

3) Switch on the 3rd brush with the desired direction of rotation.

4) Lower the 3rd brush

5) Adjust the pressure of the 3rd brush to the surface (fig. 6, no. 2).

6) Adjust the angle of the 3rd brush.

7) Engage the sprayer in case of undesired dust clouds (fig. 6, no. 9).

8) Gently push in the accelerator.

The vehicle will move slowly forward.

After working with the 3rd brush:

- the brush must be raised and placed in front of the vehicle, - the sprayer must be switched off, and - the “Stop sweeping” procedure (section 5.3) must be carried out.

Good control of the third brush can only be realized through thorough training. Inexpert operation could cause damage to the vehicle and/or the third brush system and give rise to hazardous situations.

Socket screw 8 mm

If it is necessary to tow the vehicle, the hydraulic system on the rear axle must be deactivated. To do this turn the socket screws in the middle of both hub caps 6 to 8 turns clockwise, in the direction of “TOW” The vehicle is now ready to be towed.

Figure 36: Socket screw in hub cap

The vehicle may only be towed by means of a bar. This is

because the vehicle does not have sufficient braking power when the diesel engine is switched off.

The towing speed must be limited to max. 15 km/h.

The power steering is deactivated during towing. Nevertheless, the vehicle can be steered. The steering wheel offers more resistance, but it will not damage the vehicle.

9. DAILY MAINTENANCE AND CHECKLIST

During daily maintenance the safety regulations and measures described in section 2.2, 2.5 and 2.7 must be taken into account and the following must be complied with: Switch off the engine completely. Apply the parking brake. Switch off the electrical circuit completely by means of the main electrical

switch. Lock the emergency stop in the cabin with the matching key, so that the

vehicle is completely deactivated. Tipping the hopper:

o Tip the hopper completely, and o Secure the hopper with the safety supports.

For other maintenance work we refer to the technical service manual that is supplied with the A85.

9.1. Checkpoints before sweeping

A fixed number of points must be checked every day before the vehicle is used. This is done to ensure that risks are kept to a minimum once the vehicle is being operated. 1) Leak

Check that no oil, fuel and/or water is leaking from the vehicle. Take a tolerable margin into account. Contact a technician in the event of leaks.

2) Motor oil level

Check the motor oil level with the dipstick. This is located on the side of the diesel engine. The oil level must be between the marks on the dipstick. Contact a technician if the motor oil level deviates.

3) Coolant level

Check the coolant level when the engine is cold. The reservoir is mounted on the rear of the cabin. The level must be visible between the markings (fig. 37). Contact a technician if the coolant level deviates.

4) Diesel oil level

On the fuel tank gauge on the information display (see section 3.7) check whether the fuel volume in the diesel tank is sufficient. Fill up if necessary.

5) Hydraulic fluid level

Check the hydraulic fluid level on the gauge in the engine compartment, on the rear left against the hydraulic tank. Contact a technician if the hydraulic fluid level deviates.

6) Air filter indicator

If the air filter indicator on the information display lights up (see section 3.7), contact a technician.

7) Dirt hopper Make sure that the dirt hopper is lowered completely. Make sure that the push plate is in the most forward position inside the hopper (high dump only).

8) Rear door

Ensure that the rear door is closed and locked. 9) Inspection hatches

Ensure that the inspection hatches are closed and locked. 10) Manual suction unit (optional)

Ensure that the manual suction unit is locked when it is connected. 11) Suction mouth and brushes

Check the settings of the suction mouth and brushes. Adjust the suction mouth and brushes if necessary (see section 9.2).

12) Water system

Follow the “Starting the vehicle” procedure (section 4.2). Switch on the water pump (fig. 6, no. 15) and the sprayer bar (fig. 6, no. 13). Check if water is leaking from the suction mouth. When "high pressure" (fig. 6, no.

14) more water should be leaking from the suction mouth. Contact a technician if that is not the case.

13) Lights

Check all the vehicle's lights, including the beacons. Warn a technician if the lights are not functioning properly.

14) Safety provisions

Check: - The reverse acoustic signal, - The tipping/lowering acoustic signal, - The rear door open/close acoustic signal, - The tipping/lowering flashing light, - The action of the emergency stops, - The starting safeguard by using the hand brake, - the functioning of the sensor mat in the seat.

Contact a technician if any function is not operating properly.

9.2. Settings

For good sweeping results a correct setting of the following: the suction mouth, the brush angle, and the brush pressure is essential

9.2.1. Adjusting the suction mouth

The degree of suction power is influenced by the setting of the suction mouth. The distance between the suction mouth and the road surface is determined by the guide wheel attached to the suction mouth. With the guide wheel on the ground, this distance should be approx.:

- 35 mm at the front. - 15 mm at the back (see fig. 38).

he rubbers must connect properly and must not be worn to maintain good suction power.

9.2.2. Adjusting the brush angle

sideways angle in relation to the surface that has to

15 mm

Adjustment

Figure 38: Adjusting the suction mouth TReplace the rubbers when the opening to the road surface becomes too large.

The brushes can be set at a forward and be swept. The correct setting depends on several circumstances such as the condition of the litter, the surface or the brush wear.


- 71 -

TENNANT A85

When the brushes are set a forward angle, the rear of the brush does not touch the surface. This brings the rubbish in front of the suction mouth so that it does not revolve with the brush. The sideways angle is adjusted to the shape of the surface or the degree of brush wear. Some vehicle models are equipped with a hydraulic sideways adjustment which can be operated from the cabin.

If the sideways angle is too large, it will create space between the brush and the suction mouth, leaving a line of rubbish behind. This effect increases with increased brush wear.

- Turn bolts ‘B’ to the right to increase the forward angle.

- Turn bolts ‘B’ to the left to decrease the forward angle.

3) Set the sideways angle: - Tilt the brush by hand to adjust

the sideways angle to the surface. 4) Once the correct setting as been

obtained, tighten the 2 nuts ‘A’. Figure 39: Adjusting the brush angle

9.2.3. Adjusting the brush pressure

The correct setting for the brush pressure among other things depends on the type of litter, the surface, the brush wear and the driving speed. Taking into account these circumstances an acceptable brush pressure must be selected. Figure 40 1) Use the supplied adjustment spanner. 2) Adjust the brush pressure

- Turn the spanner to the right to decrease the brush pressure.

- Turn the spanner to the left to increase the brush pressure.

9.3. Maintenance after sweeping

A number of fixed maintenance tasks must be carried out daily after sweeping is completed. For this maintenance work the hosing-down hose, the high-pressure lance (optional) or a high-pressure cleaner can be used. Chapter 6 contains a detailed description of the use of the hosing-down hose and the high-pressure lance (optional).

The hand brake must be engaged during cleaning of the vehicle. The doors, windows and see-through hatch of the cabin must be closed

during cleaning of the vehicle with the hosing-down hose, the high-pressure lance or high-pressure cleaner.

The engine compartment may only be cleaned when the engine is switched off. Therefore, the hosing-down hose and the high-pressure lance cannot be used for this purpose.

9.3.1. Suction mouth and suction hose

Clean the suction mouth and suction hose. Also clean the inside of the suction hose:

o Carry out the "Starting the vehicle" procedure (section 4.2) (engine speed ±1400 revs/min.).

o Temporarily switch on the suction fan and the water pump. o Clean the inside of the suction hose:

Maintain a sufficiently safe distance from the vehicle while the diesel engine is switched on.

9.3.2 Sweeping unit Remove dirt from the sweeping unit with excess water.

9.3.3. Blow-off chamber and standard hopper

-Open the rear door completely.

-Fully tip the dirt hopper and extend the safety supports.

-Clean the blow-off chamber and dirt hopper with water.

-Fully lower the hopper.

-Clean the ventilation grid via the inspection hatches. If there is a dirt hopper cleaning system, lower it for the cleaning of the mesh and fan, lift the system after cleaning

-Clean the rear door seal

-Close the rear door

9.3.4. Blow-off chamber and high dump hopper

-Open the rear door completely.

-Fully tip the dirt hopper at the front and extend the short safety supports.

-Clean the blow-off chamber and dirt hopper with water. Pay special attention to the guiding of the push plate.

-Move the push plate to the most outer position, so that the lower edge is cleared from the hopper bottom.

-Clean the dirt hopper behind the push plate with water. The area behind the push plate can be reached through the hopper side doors and the front door in the push plate. Also clean the guiding of the push plate.

-Clean the ventilation grid via the inspection hatches.

-Fully retract the push plate.

-Fully lower the hopper.

-Clean the rear door seal

-Close the rear door

9.3.5. Engine compartment and chassis

Before cleaning the engine compartment: Fully tip the dirt hopper and extend the safety supports. Switch off the engine completely.

Clean the entire engine compartment and chassis with water. Care should be taken when cleaning with high pressure.

9.3.6. Exterior of the vehicle Once the cabin is closed properly, clean the vehicle on the outside with water. Strictly avoid chemical cleaning agents.

9.3.7. Cabin

The interior of the cabin may only be cleaned with a brush and a moist cloth. So no excessive use of water! So no excessive use of water!

Thoroughly clean the see-through hatch and the windows.

11. INTEGRATED AIR CONDITIONING/HEATING SYSTEM

11.1. Setting the temperature of the heater (5P1) and the airco system (5P2)

Temperature setting heater (heater on: lamp out 1 on) Press set once. Go to 5P1 with the arrow keys. When 5P1 appears in the display, press “Set”. Adjust the temperature by pressing the up or down arrow keys. After the adjustment, press “Set”. Wait 15 seconds: the actual cabin temperature appears in the display. This completes the temperature setting for the heater. Temperature setting airco system (airco on: lamp out 2 on) Press set once. Go to 5P2 with the arrow keys. When 5P2 appears in the display, press “Set”. Adjust the temperature by pressing the up or down arrow keys. After the adjustment, press “Set”. Wait 15 seconds: the actual cabin temperature appears in the display. This completes the temperature setting for the airco.

Attention! » The heater and air co system only function when the blower has been switched on (fig. 5, no. 19). » To prevent the heater from switching on during warm periods, the heater temperature must be set lower than the temperature for the air co system. » If the cabin has been heated too strongly, the best thing to do is to open the window for a little while to allow the hottest air to escape. However, the best cooling is achieved when the windows are subsequently closed entirely. »The optimum difference between the inside and outside temperature lies between 4 and 6 degrees. A larger temperature difference may cause colds. » The adjustable outflow mouths can best be aimed at the source of heat or the window and not directly at the people inside the cabin. » The heating and air conditioning can be used simultaneously for a large part of the year. The air is then first dehumidified by the air co system and subsequently brought up to an agreeable temperature by the heater. This results in a very quick demisting of the windows, even when the people inside are wearing damp clothes. The setting should then be as follows: set the air co system 2° lower and the heater 2° higher than the inside temperature.

To prevent problems, the following items need periodical attention: Activate the system at least once a week. Switch on the system when the engine speed is as low as possible. Weekly check the condenser for dirt and bent lamella that hamper the air flow. Clean the lamella against the air flow. Depending on use, regularly check:

- the tension and condition of the drive belt - the condition of the coolant hoses

Regularly check the filter inside the cabin and replace when necessary. Once a year exchange the dryer/filter (rear of cabin).
