There are three adjusting screws for adjusting thecarburetor:

• Low speed jet• High speed jet• Adjustment screw for idling

Adjusting the carburetor involves adapting theengine to local operating conditions, e.g. climate,altitude, gasoline and type of two-stroke engine oilused.For details about carburetor adjustment, see page18.

English – 11

FUEL HANDLING

WARNING!Allow adequate ventilation whilehandling fuel.!

Two-stroke oil

• For the best performance, use HUSQVARNAtwo-stroke oil, which has been speciallydeveloped for Husqvarna two-stroke engines.Mixing ratio: 1:50 (2%).

• If HUSQVARNA two-stroke oil is not available,you may use another two-stroke oil of goodquality that is intended for air-cooled engines.Contact your dealer when selecting an oil.Mixing ratio: 1:33 (3%).

• Never use two-stroke oil intended for water-cooled marine outboard motors, so-calledoutboard oil.

• Never use oil intended for four-stroke engines.

NOTE!The machine is fitted with a two-stroke engine andmust always be run on a mixture of petrol and two-stroke oil. It is important to measure the quantity ofoil accurately, to ensure the correct mixture ratio.Small discrepancies in the amount of oil have agreat bearing on the proportions of the fuel mixturewhen mixing small amounts of fuel.

Fuel

Petrol

NOTE!Always use an oil-mixed quality petrol (at least90 octane). If your machine is equipped with acatalytic converter, (see “technical data”) anunleaded, oil mixed quality petrol should alwaysbe used. A leaded petrol will destroy thecatalytic converter.

• The lowest recommended octane rating is 90. Ifyou run the engine on a petrol with a loweroctane rating than 90 so-called “knocking“ canoccur. This leads to an increased enginetemperature, which can result in a seriousengine breakdown.

• When working at continuous high revs a higheroctane rating is recommended.

MAINTENANCE

The fuel quantity required in relation to the air flow,provided by the opening in the throttle, is adjustedby the L and H jets. If they are screwed clockwise,the air/fuel mixture becomes leaner (less fuel) and ifthey are screwed counterclockwise, the mixturebecomes richer (more fuel). A leaner mixture givesrise to a higher engine speed and a richer mixturegives rise to a lower engine speed.

The T screw regulates the idling speed. Turning theT screw clockwise will increase the idling speed;turning it counterclockwise will lower the idlingspeed.

The carburetor has been carefully preset at the fac-tory. However, additional adjustment may be requireddue to climate, altitude, gasoline and type of two-stroke engine oil used. The instructions belowdescribe how carburetor adjustment should becarried out.

Function

The carburetor governs the engine speed via thethrottle. Air and fuel are mixed in the carburetor. Theair/fuel mixture is adjustable. To utilize the blower’smaximum output, the settings must be correct.

The carburetor has three means of adjustment:

H = High speed jetL = Low speed jetT = Adjustment screw for idling

Carburetor

H L T

Basic (factory) settingsThe carburettor is preset to the basic settings whenthe blower is tested at the factory. These basicsettings are the following:

Turn the H jet screw CCW against its stop.Turn the L jet screw CCW against its stop.

The recommended idling speed is 3,000 rpm.

AdjustmentTo adjust the low speed jet (L)1. Check that tube (15) and nozzle (14) are

mounted on the blower.2. Turn the H and L jet screws all the way CCW

against the stop.3. Start the blower as described on page 13 and

alternate letting it run at idling speed and at halfthrottle for 1 – 2 minutes to warm up. If theengine will not run at idling speed, turn the Tscrew CW until it does.

4. Turn the T jet screw until the engine runsprecisely at idling speed without dying.

5. Make a fine adjustment, turning the L screw tolet the engine run at max. idling speed. Thenturn the L screw max. 1/4 of a turn CCW.

6. Turn the T screw to increase the engine speed,if necessary.

To adjust the high speed jet, H

NOTE !When setting the H jet, do not let theengine run at full throttle for more than 10seconds at a time. Alternate by letting theengine run at idling speed for at least 10seconds before giving it full throttle again.

1. Start the blower as described on page 13 andalternate letting it run at idling speed and at halfthrottle for 1 – 2 minutes to warm up.

2. Give the engine full throttle and adjust the H jetscrew until the engine runs at max. speed.

3. Turn the H jet screw 1/8 of a turn counter-clockwise (less than 1/8 of a turn if a stoprestricts this adjustment).

MAINTENANCE

NOTE!Some mufflers are fitted with catalytic converters.See “Technical data” to find out if your machine isequipped with a catalytic converter.

The muffler is designed to dampen the noise leveland to direct the exhaust fumes away from the user.The exhaust fumes are hot and can contain sparks,which can result in fire if the exhaust fumes aredirected towards a dry and inflammable material.Some mufflers are equipped with a special sparkarrest screen. If your machine is fitted with this typeof screen it should be cleaned regularly. This isdone using a wire brush. On mufflers without acatalytic converter the screen should be cleanedweekly, or replaced if necessary. On mufflers fittedwith a catalytic converter the screen should bechecked and cleaned monthly. If the screen isdamaged it should be replaced . If the screen isfrequently blocked, this can be a sign that thefunction of the catalytic converter is impaired.Contact your dealer to inspect the muffler. A blockedscreen will cause the engine to overheat resulting indamage to the cylinder and piston. Also see under“Maintenance”.

NOTE!Never use a machine with a defective muffler.

The engine is equipped with a cooling system formaintaining the right operating temperature.

The cooling system consists of the followingcomponents:

1. Air intake on the starter device.2. Fan blades on the flywheel.3. Cooling fins on the cylinder.4. Cylinder cowling (guides cooling air flow against

cylinder surfaces).

Clean the cooling system by brushing once a week,or more often, if necessary.A dirty or blocked cooling system will cause theblower to overheat and this will damage the cylinderand piston.

Cooling system

B A

The air filter (A) must be cleaned regularly to re-move dust and dirt. This will prevent:

• Carburetor malfunctions• Starting problems• Reduced performance• Unnecessary wear on engine parts• Abnormal fuel consumption• Elevated content of harmful exhaust fumes

Clean the filter after 25 hours of operation or moreoften if the air is exceptionally dusty in the workarea.

To clean the air filterDismantle the air filter cover (B) and remove thefilter medium. Wash it clean in a solution of soapand warm water. Make sure that the filter is drybefore reassembling.An air filter, which has been used for some time, can-not be cleaned completely. Therefore, the filter mustbe replaced by a new one at regular intervals. Afaulty filter must always be replaced.

MAINTENANCE

Air filter

Spark plugThe condition of the spark plug is influenced by:

• An incorrectly adjusted carburetor.• Wrong fuel mixture (too much oil in the

gasoline).• Poor quality gasoline and/or oil.• A dirty air filter.

These factors cause deposits on the spark plugelectrodes, which may result in malfunction anddifficulty starting the blower.

If the engine is low on power, difficult to start orruns poorly at idling speed, always check thespark plug first.

The spark plug is accessible under the cylindershrouding, which can be removed by unscrewingfour screws.

If the spark plug is clogged, clean it and check theelectrode gap. Re-adjust if necessary. The correctgap is 0.5 mm (0.020”). The spark plug should bereplaced after about one month of operation orearlier if the electrodes are badly eroded.

NOTE! Always use the recommended type of sparkplug! See under ”Technical data”. An incorrect sparkplug can severely damage the piston/cylinder.
