5.5.1. Safe driving procedures are covered in IFSTA Pumping Apparatus Driver/Operator Handbook, IAW NFPA 1002, Standard for Fire Apparatus Driver/Operator Professional Qualifications. 5.5.2. Before driving.
5.5.2.1. Whenever possible, make runs with a full water tank. This will prevent the water from “sloshing” and will minimize unpredictable shifts in the load and vehicle control. It is important to note that the increased load will also cause the center of gravity to become higher. 5.5.2.2. Tire pressure can be adjusted to increase handling on poor-weather and off-road surfaces. The driver must determine the tire pressure that provides the desired balance between off-road mobility, poor weather handling, and on-road performance. 5.5.2.3. Upon entering the vehicle cab, adjust the seat position. Make sure there is sufficient clearance between the head and the cab roof at the seat’s maximum upward travel. Serious injury may occur if head clearance is not adequate. 5.5.2.4. Fasten seat belts immediately after adjusting the seat height and before moving the vehicle. All persons riding in the vehicle cab must be seated in approved riding positions and secured by seat belts any time the vehicle is in motion. Failure to use seat belts can result in serious injury or death. 5.5.2.5. Before starting the vehicle engine, completely understand the function of all gauges and know their normal readings. The operator must also understand the operation of all switches and vehicle controls.
5.5.2.6. Make sure to read and follow the start-up and shut-down procedures before starting the vehicle engine. Failure to follow proper start-up and shut-down procedures may result in severe engine damage.
5.5.3. General Safe Driving Procedures. Safe driving procedures are covered in IFSTA Aircraft Rescue and Firefighting, Fourth Edition, Chapter 8, Aircraft Rescue and Firefighting – Apparatus Driver/Operator, IAW NFPA 1003, Standard for Airport Firefighter and NFPA 1002, and Standard on Fire Apparatus Driver/Operator Professional Qualifications.
5.5.3.1. Always hold the steering wheel firmly on both sides to allow maximum control. 5.5.3.2. Look ahead of the moving vehicle (12 to 15 seconds) to prepare and adjust for upcoming obstacles. This means that the line of vision is on objects that will be passed within 12 to 15 seconds at the current rate of travel. 5.5.3.3. In an emergency situation, DRIVE DEFENSIVELY. Even though the operator is in a hurry, they must be extra observant of airport vehicles and equipment. 5.5.3.4. Take turns slowly. This vehicle's center of gravity can be as high as 6 feet (1.8 m) off the ground. This is very high relative to other automobiles; most have a center of gravity only 1-1/2 to 2-feet (46 to 61 cm) from the ground. All vehicles are vulnerable to roll-over if safe driving habits are not observed. Remember, the higher the speed is, the larger the safe turning radius becomes. 5.5.3.5. When turning, DO NOT attempt to estimate the speed. Check the speedometer BEFORE making the turn in order to estimate how much to slow down. The vehicle's smooth riding suspension, the high visual perspective in the cab, and the lack of consistent reference points makes it easy to underestimate the current speed. 5.5.3.6. Brake BEFORE a curve or a turn, and accelerate slightly through it to maintain control. 5.5.3.7. DO NOT brake while the wheels are turned, as it could result in loss of control, skidding, and possible roll-over. 5.5.3.8. When responding to emergencies, accelerate fast while straight, but brake hard before going into a turn or curve. 5.5.3.9. Slow down enough before turning the steering wheel so there is not a need to brake again until completing the turn. 5.5.3.10. If skidding occurs, DO NOT allow the wheels to lock while attempting to brake. For vehicles equipped with the optional anti- lock brake system (ABS), brake hard. The ABS computer will automatically prevent lock-up.
5.5.3.11. For vehicles without ABS or if the ABS is inoperative, modulate or "pump" the brakes to slow the vehicle. 5.5.3.12. To recover from a skid, quickly turn the steering wheel in the desired direction. As the vehicle gets back on course, quickly counter-steer to prevent the vehicle from skidding in the opposite direction. 5.5.3.13. When making lane changes or negotiating curves, allow the vehicle to return to its normal straight ahead, balanced position before turning the steering wheel in the opposite direction. The smooth suspension enables the vehicle to travel at high speeds; however, it also decreases the high speed maneuverability of the vehicle. 5.5.3.14. Remember the vehicle is equipped with a large water tank. Liquid causes increased difficulty when changing the direction of motion, especially when carrying a partial load. Tank trucks can overturn around curves, even at slow speeds. The water tank is equipped with baffles in both directions to help reduce this effect; however, when driving a tank vehicle, the straight path is the best path.
5.5.4. Higher rollover risk. Avoid abrupt maneuvers and excessive speed. 5.5.5. Right turns.
5.5.5.1. Turn slowly, give the vehicle and others more time to avoid problems. 5.5.5.2. Make the right turn without swinging into another lane. 5.5.5.3. Prevents vehicles passing on the right. 5.5.5.4. If the operator must cross into the oncoming lane to make a turn: Watch for vehicles coming toward the vehicle being operated; give them room to go by; stop; do not back up for them.
5.5.6. Left turns.
5.5.6.1. Ensure the vehicle has reached the center of intersection before starting the left turn. 5.5.6.2. If two left turn lanes, take the right-hand lane.
5.5.7. Space needed to cross or enter traffic.
5.5.7.1. Slow acceleration and the space large vehicles require. 5.5.7.2. Acceleration varies with the load.
5.5.8. Poor Weather:
5.5.8.1. Pay close attention to the weather and surface conditions while driving. Snow and ice can be a problem, especially in shaded areas. If a vehicle slides on a patch of ice and then suddenly hits dry pavement, the sudden stop may result in roll-over, even at speeds under 10 mph (16 km/hr.). 5.5.8.2. Rain can cause slick conditions, especially just after the rain begins. The stopping distance of the vehicle will double on wet roads. 5.5.8.3. Hydroplaning can occur if standing water is present. At high speeds, the tires may be unable to displace the water, resulting in a film of water between the tires and the driving surface. This will lead to loss of braking and steering control. Increased tire pressure and slower speeds will help to reduce the chance of hydroplaning when driving through standing water.
5.5.9. Braking During Slippery Conditions.
5.5.9.1. ABS Equipped Vehicles. Step hard on the brake until the vehicle has stopped. DO NOT pump the brakes, as this will confuse the ABS and cause it to work improperly. 5.5.9.2. Vehicles without ABS or with Inoperative ABS. DO NOT allow the wheels to lock. To prevent this, modulate or “pump” until the vehicle has stopped.
5.6. P-19 Oshkosh UHP Firefighting Truck Vehicle Operation.
5.6.1. Pre Operational Checks. IAW AFI 23-302, operators shall not delay discrepancy reporting on systems or devices adversely affecting the safety of personnel or the operation of vehicles and equipment. Do not delay maintenance reporting, nor let the vehicle or equipment item continue in service, for the discrepancies listed below.
5.6.1.1. Ensure all windows and mirrors are clean. 5.6.1.2. Adjust driver’s seat to the most comfortable operating position. 5.6.1.3. Adjust the mirrors to provide unobstructed views to the rear, sides, and front of the truck. 5.6.1.4. Do not attempt to engage the front axle interlock if either rear tire is spinning or under a torque condition (accelerator pedal applied). Drive line damage could occur. Do not attempt to disengage the front axle interlock under a torque condition or damage could again occur to the driveline. 5.6.1.5. Fasten safety belt and ensure all passengers are properly secured.
5.6.2. Starting the Vehicle. Observe the following procedures when starting the vehicle engine:
5.6.2.1. Make sure that the parking brake knob is pulled out so that the parking brakes are applied. 5.6.2.2. Make sure that the parking brake knob is pulled out so that the parking brakes are applied. 5.6.2.3. Turn ignition switch to the ON position. 5.6.2.4. Wait for system to go through start up sequence. 5.6.2.5. Turn and hold ignition until vehicle starts. 5.6.2.6. Observe the engine gauges and warning lights for proper readings. 5.6.2.7.

5.6.6.1. Observe the following procedure when stopping the vehicle engine:
5.6.6.1.1. Bring the vehicle to a stop, place the transmission gear range selector in neutral (N) and apply the parking brake by pulling out the control knob. 5.6.6.1.2. Allow the engine to run between idle (600 rpm) and 1000 rpm with no load for at least 3 minutes. This allows the engine to cool and permits the turbocharger to slow down. 5.6.6.1.3. Turn-off all accessories.
5.7. Firefighting Systems Operation.
5.7.1. The following paragraphs will describe operating procedures necessary for all firefighting missions for which the vehicles were designed. It is strongly recommended that all personnel required to operate the vehicles study the contents of these procedures thoroughly and practice the safety precautions specified.
5.7.2. Water/Foam ARFF System.
5.7.2.1. The firefighting system is designed so that either water or foam can be discharged without interruption while the vehicle is in motion, standing still, or maneuvering over rough terrain. The firefighting system discharge controls, gauges, and instrumentation are arranged on the RH dash switch panel and dash, and may be operated by either the driver or an operator. 5.7.2.2. Engaging the water (blue) or foam (yellow) mode switch by pressing up for 3-5 seconds, on the RH dash switch panel engages the pump clutch. The pump will then be turning at an rpm in relation to the engine rpm. This will also restrict the transmission to 1st and 2nd gear.
5.7.2.2.1. Pressing the foam (yellow) rocker switch will activate the water pump. If only water is needed use the (blue) rocker switch.
5.7.2.2.2. When a discharge switch is engaged to activate a discharge outlet (i.e. turret, etc.) the modulating clutch in the power divider will disengage for pump-and-roll operation, and the engine rpm will be brought up to governed pumping rpm.
5.7.3. Water Pump. The water pump is protected from overheating by a temperature protection valve that will dump water to the ground when the temperature of the water in the pump is approximately 170° F. This water is replenished with cool water from the agent water tank. It is recommended that the water or foam mode switch not be engaged before coming within 300-feet of the fire; not when exiting the fire station or enroute to the fire.
5.7.4. Activating the Water/Foam Firefighting System.
5.7.4.1. Select water or foam by holding down the desired mode switch for 3-5 seconds on the RH dash switch pane. Foam switch will engage water. 5.7.4.2. Engage the bumper turret or open the nozzle on the 1” handline to start flowing.

Whenever the vehicle must operate at extended distances from the water supply, or very high discharge pressures are required to pump water to great heights the vehicle may be coupled to a hydrant or a nurse truck. 5.8.1.2. When the vehicle has reached the fire, the driver must place the transmission gear range selector in neutral (N) and apply the parking brakes. 5.8.1.3. Working on the left side of the vehicle, CLOSE the water tank shutoff valve. Make sure that the hydrant connection valve is closed. 5.8.1.4. Couple the hose to hydrant or nurse truck and to the 2-1/2-inch suction inlet on the vehicle. 5.8.1.5. If the 2-1/2-inch side discharge outlets are to be used, connect hoses and equipment as desired. 5.8.1.6. Turn the hydrant supply ON, or OPEN the discharge valve on the nurse truck. 5.8.1.7. The vehicle is now ready for structural pump operation.
5.8.2. Pumping the Agent Water Tank. 5.8.2.1. When the vehicle has reached the fire, the driver must place the transmission gear range selector in neutral (N) and apply the parking brakes. 5.8.2.2. Working on the left side of the vehicle, make sure that the water tank shutoff valve is OPEN. 5.8.2.3. If 2-1/2-inch side discharge outlets are to be used, connect hoses and equipment as desired.
5.8.3. Pumping from Draft.
5.8.3.1. When pumping from draft, water is drawn from a supply such as a pond, lake, swimming pool, etc. 5.8.3.2. Maneuver the vehicle as close as possible to the water supply. Place the transmission gear range selector in neutral (N) and apply the parking brake. 5.8.3.3. Working on the left side of the vehicle, close the water tank shutoff valve.
5.8.3.4. Make sure that all discharge connections on the vehicle are closed. 5.8.3.5. Attach the Pre-con Hydra shield automatic inlet valve (not required).
5.8.3.5.1. The Hydra shield inlet valve is used to control flow of water when drafting only. This valve must be fully opened when priming the pump. After water is flowing the handle can be moved to the middle position to allow the valve to control the flow of water into the pump. This device will also close and hold the prime if operations are switched to onboard tank.
5.8.3.6. Attach sections of 4½ -inch suction hose to suction inlet. 5.8.3.7. Attach a suction strainer to the end of the suction hose before immersing the hose in the water supply. In placing the suction hose, make sure that no part of the hose is higher than the 5- inch suction inlet on the side of the vehicle, to avoid the formation of an air pocket in the hose. 5.8.3.8. Immerse the suction strainer at least two feet below the surface of the supply water to prevent the formation of whirlpools, which will allow the pump to draw air and loose prime. 5.8.3.9. Activate the structural control panel by turning ON the master switch. All discharge outlets MUST be closed before attempting to prime the pump. 5.8.3.10. Establish water pump prime by pressing the primer button located at the structural panel. A definite change in sound of the priming pump will be heard when priming is complete, and water will be seen from the priming pump discharge line underneath the vehicle. 5.8.3.11. Engage the water mode switch on the structural control panel and adjust the engine throttle to the approximate pumping rpm by pressing the button +/- while observing engine rpm as shown on the tachometer. 5.8.3.12. Check the water pump suction gauge reading, verifying the pump is primed and developing pressure. 5.8.3.13. The vehicle is now ready for structural pumping.
5.8.4. Structural Panel Operation.
5.8.4.1. After the vehicle is setup for structural pumping in accordance with instructions for pumping from hydrant or draft; all pumping operations are controlled from the structural control panel on the left side of the vehicle.
5.8.4.2. Pressure Relief/Pilot Valve.
5.8.4.2.1. Normally stored in the OFF position. When in the ON position, the discharge relief valve allows the operator to maintain a constant pressure being discharged at multiple discharge lines. The pressure will be kept constant, even if one or more lines are closed, preventing surges at the remaining discharge lines. The desired pressure can be adjusted at the discharge relief valve. The relief valve determines the actual pressure output of the pump. The pilot valve is an adjustable, spring loaded valve that determines the pump pressure at which the relief valve opens. 5.8.4.2.2. Make sure that the water tank shutoff switch is in the OPEN position. 5.8.4.2.3. Make sure that the relief valve ON/OFF switch is set to ON. 5.8.4.2.4. Close all discharges. 5.8.4.2.5.

OPERATION & TROUBLESHOOTING GUIDE FOR THE AIR FORCE IDLE REDUCTION TECHNOLOGY (IRT) SYSTEM
A5.1. Idle Reduction Technology (IRT) Overview. IRT describes the technology and practices that minimize the amount of time operators idle their engines. Avoiding idling time has a multitude of benefits including: savings in fuel and maintenance costs, extending vehicle life, and reducing damaging emissions. This truck is equipped with this technology. A5.2. Enabling IRT. There is only one way to enable IRT on this unit, the following conditions have to be met for 2 minutes for the multiplexing system to request the generator to automatically start. If any of the conditions change from the state mentioned the timer will reset to zero and will restart once they are met again:
A5.2.1. Truck engine running. A5.2.2. Transmission is in neutral. A5.2.3. Park brake is applied. A5.2.4. Pump not engaged. A5.2.5. Generator is not running. A5.2.6. IRT disable switch off (down position). A5.2.7. Generator DC control breaker switch is ON.
A5.3. IRT Mode. No more than 5 seconds after the generator auto starts (2 min of idling) the truck engine will automatically shut OFF. Approximately 5 seconds after the engine automatically shuts OFF the converters will switch the truck over to generator power at this point the truck is considered to be IRT mode.
A5.3.1. In IRT mode the following 120v items WILL be powered up:
A5.3.1.1. Block heaters.
A5.3.1.2. Climate control system (Penguin).
A5.3.1.3. Oil heaters.
A5.3.1.4. Pan heaters.
A5.3.1.5. Battery heater.
A5.3.1.6. Battery chargers.
A5.3.1.7. IRT converters.
A5.3.2. In IRT mode the following 12V items WILL be powered:
A5.3.2.1. Radios. A5.3.2.2. DOT lighting. A5.3.2.3. NFPA required emergency lights. A5.3.2.4. Step lights. A5.3.2.5. Work lights. A5.3.2.6. Compartment lights.
A5.3.3. In IRT mode the following 120V items will NOT be powered:
A5.3.3.1. Lights. A5.3.3.2. Reels. A5.3.3.3. Receptacles.
A5.3.4. The truck is considered to be in Generator mode when converters are not enabled and the generator was manually started with the truck running this mode the gen will need to have manual preheat applied via the switch in the overhead driver side before the gen is started. Gen mode the following 120V items WILL be powered:
A5.3.4.1. Reel. A5.3.4.2. Receptacles.
A5.3.5. To switch from IRT mode to normal operation mode:
A5.3.5.1. Bring Ignition switch one click down to Master power. A5.3.5.2. Wait for generator to turn-off. A5.3.5.3. Wait 2 seconds. A5.3.5.4. Power back up and start truck.
A5.4. IRT Operating Indicator. Light found in overhead driver side.
A5.4.1. The IRT operating indicator will flash 120 fpm when disable switch is in “ON” position indicating IRT CANNOT be enabled. Not flashing if service switch is OFF, steady burn indicates IRT is operating a custom flash pattern when the DC control breaker found on the generator is in the OFF position. A5.4.2. If the generator cranks but does not run within approx. 10 sec of the request to start, cycle power to truck and with engine not running verify generator functionality manually via the manual start button in the overhead or with the switch found on the generator itself. A5.4.3. If generator is running but does not switch over, verify converter breakers and solenoids are working properly, converters not switching over will sound the reverse alarm.
Figure A5.1. Troubleshooting IRT Problems.
Troubleshooting IRT Problems Symptom Possible Solution
Generator does not automatically start after 2 minutes of truck idle.
Verify that: Truck engine is running; Transmission is in neutral; Park Brake is applied; Pump not engaged; Generator is not running; IRT disable switch is off (down position); Switch on generator is in the ON position. Manually change state to each command mentioned above. Cycle power to truck. Contact local dealer for support.
Generator running but converters do not power up.
Verify that the generator started automatically after truck has been idling for 2 min. Verify that the coil side of relay has 12 volts to ground. If not, contact local dealer for support.

SEVEN-STEP INSPECTION PROCESS Figure A6.1. Seven-Step Inspection Process.
Seven-Step Inspection Process Step Procedure 1. Vehicle Overview • Review the AF Form 1800.
o Ensure any discrepancy has been corrected.
o Vehicle Management annotated the discrepancy was completed.
o Approaching the vehicle. Damage or vehicle leaning to one
side. Fresh leakage of fluids. Hazards around vehicle.
2. Check Engine Compartment • Note: Check that the parking brakes are on and/or wheels chocked. The operator may have to raise the hood, tilt the cab (secure loose things so they don't fall and break something), or open the engine compartment door.
• Check the following: o Engine oil level. o Coolant level in radiator; condition of
hoses. o Power steering fluid level; hose
condition (if so equipped). o Windshield washer fluid level. o Battery fluid level, connections and
tie-downs (battery may be located elsewhere).
o Automatic transmission fluid level (may require engine to be running).
o Check belts for tightness and excessive wear (alternator, water pump, air compressor)--learn how much "give" the belts should have when adjusted right.
o Leaks in the engine compartment (fuel, coolant, oil, power steering fluid, hydraulic fluid, battery fluid). Cracked, worn electrical wiring insulation.
3. Start Engine and Inspect Inside the Cab (Get in and Start Engine)
• Make sure parking brake is on. • Put gearshift in neutral (or park if
automatic). Start engine; listen for unusual noises.
• If equipped, check the Anti-lock Braking System (ABS) indicator lights. Light on dash should come on and then turn-off. If it stays on the ABS is not working properly.
• Note: For trailers only, if the yellow light on the left rear of the trailer stays on, the ABS is not working properly.
• Look at the gauges. o Oil pressure. Should come up to
normal within seconds after engine is started.
o Air pressure. Pressure should build from 50 to 90 psi within 3 minutes. Build air pressure to governor cut-out (usually around 120 – 140 psi. Know the vehicle’s requirements.
o Ammeter and/or voltmeter. Should be in normal range(s).
o Coolant temperature. Should begin gradual rise to normal operating range.
o Engine oil temperature. Should begin gradual rise to normal operating range.
o Warning lights and buzzers. Oil, coolant, charging circuit warning, and antilock brake system lights should go out right away.
o Check Condition of Controls. Check all of the following for looseness, sticking, damage, or improper setting:
Steering wheel. Clutch. Accelerator (gas pedal). Brake controls. Foot brake. Trailer brake (if vehicle has one). Parking brake. Retarder controls (if vehicle has
them). Transmission controls. Interaxle differential lock (if vehicle
has one). Horn(s). Windshield wiper/washer. Lights. Headlights. Dimmer switch. Turn signal. Four-way flashers. Parking – clearance – identification –
marker switch (switches). • Check mirrors and windshield. o Inspect mirrors and windshield for
cracks, dirt, illegal stickers, or other obstructions to seeing clearly. Clean and adjust as necessary.
• Check emergency equipment. o Check for safety equipment: Spare electrical fuses (unless vehicle
has circuit breakers). Three red reflective triangles, 6 fuses
or 3 liquid burning flares.
Properly charged and rated fire extinguisher. Check for optional items such as:
Chains (where winter conditions require).
Tire changing equipment. List of emergency phone numbers
Accident reporting kit (packet). o Check safety belt. Check that the
safety belt is securely mounted, adjusts; latches properly and is not ripped or frayed.

manifests, permits, etc. o Secure all loose articles in cab (they
might interfere with operation of the controls or hit the operator in a crash).
o Start the engine.
7. Start the Engine and Check Test for Hydraulic Leaks
• Test for hydraulic leaks. o If the vehicle has hydraulic brakes,
pump the brake pedal three times. o Then apply firm pressure to the pedal
and hold for five seconds. o The pedal should not move. If it
does, there may be a leak or other problem.
• Brake system. • Test parking brake. o Fasten safety belt. o Set parking brake (power unit only).
Release trailer parking brake (if applicable). Place vehicle into a low gear.
o Gently pull forward against parking brake to make sure the parking brake holds.
o Repeat the same steps for the trailer with trailer parking brake set and power unit parking brakes released (if applicable).
o If it doesn't hold vehicle, it is faulty; get it fixed.
• Test service brake stopping action. o Go about 5 miles per hour. o Push brake pedal firmly. o "Pulling" to one side or the other can
mean brake trouble. o Any unusual brake pedal "feel" or
delayed stopping action can mean trouble.
o If the trainee finds anything unsafe during the Vehicle inspection, get it fixed. Federal and state laws forbid operating an unsafe vehicle.
• Check vehicle operation regularly: o Instruments. o Air pressure gauge (if the vehicle has
air brakes). Temperature gauges.
o Pressure gauges. Ammeter/voltmeter.
o Mirrors. o Tires. o Cargo, cargo covers. Lights, etc. o If the trainee sees, hears, smells, or
feels anything that might mean trouble, he/she should check it out.
• Safety inspection. o Drivers of trucks and truck tractors
when transporting cargo must inspect the securement of the cargo within the first 50 miles of a trip and every 150 miles or every 3 hours (whichever comes first) after.
• Document any discrepancy on AF Form 1800. Sign-off AF Form 1800 to signify accomplishment of inspection.
Figure A6.2. Additional Steps for Inspecting Air Brakes System.
Additional Steps for Inspecting Air Brakes Step Procedure
2. Engine Compartment Checks • Check air compressor drive belt condition and tightness (if compressor is belt driven).
5. Walk-Around Inspecting • Check manual slack adjusters on S-cam brakes. Note: Vehicles with automatic slack adjustors still must be checked.
o Park on level ground and chock the wheels. o Release the parking brakes so the operator can
move the slack adjusters. o Use gloves and pull hard on each slack
adjuster that it can be reached. o Check slack adjuster, more than 1-inch
indicates adjustments required (vehicles with too much brake slack can be very hard to stop). Adjust it or have it adjusted.
• Check brake drums (or discs), linings, and hoses.
7. Final Air Brake Check • Test low pressure warning signal. o Shut the engine off when the vehicle has
enough air pressure so that the low pressure warning signal is not on.
o Turn the electrical power on. o Step on and off the brake pedal to reduce air
tank pressure. o Low air pressure warning signal should come
on before the pressure drops to less than 60 psi in the air tank with lowest pressure.
• Check that the spring brakes come on automatically.
o Chock the wheels. o Release the parking brakes when enough air
pressure is built up. o Shut the engine off. o Step on and off the brake pedal to reduce the
air tank pressure. o "Parking brake" knob should pop out when
the air pressure falls to the manufacturer's specification.
• Check rate of air pressure buildup o Refer to manufacturer’s recommendation for
average buildup time.
o If not within recommended time, the air pressure may drop too low during driving operations.
• Test air leakage rate. o With a fully-charged air system (typically 125
psi). o Turn-off the engine. o Release the service brake and time the air
pressure drop. o The loss rate should be less than 2 psi in one
minute for single vehicles. o Not less than 3 psi in 1 minute for
combination vehicles. • Then apply 90 psi or more with the brake
pedal. o After the initial pressure drop, if the air
pressure falls more than 3 psi in 1 minute for single vehicles.
o Not more than 4 psi for combination vehicles. • Check air compressor governor cut-in and
cut-out pressures. o Air compressor should start at about 100 psi
and stop at about 125 psi. o Run the engine at a fast idle. o Air governor should cut-out the air
compressor at about the manufacturer's specified pressure.
o Engine idling, step on and off brake to reduce air tank pressure.
o Compressor should cut-in at manufacturer's specified cut-in pressure.
o Test parking brake: Stop the vehicle; put the parking brake on; gently pull against it in low gear to determine if parking brake will hold.
Test service brakes. Wait for normal air pressure. • Release the parking brake. • Move the vehicle forward slowly (about 5
mph). • Apply the brakes firmly using the brake pedal. • Note any vehicle "pulling" to one side,
unusual feel, or delayed stopping action.
