NOTE!The machine is fitted with a two-stroke engine and mustalways be run on a mixture of gasoline and two-stroke oil. It isimportant to measure the quantity of oil accurately, to ensurethe correct mixture ratio. Small discrepancies in the amount ofoil have a great bearing on the proportions of the fuel mixturewhen mixing small amounts of fuel.

Mixture

• Always mix gasoline and oil in a clean container intendedfor fuel.

• Always start by filling half the quantity of gasoline required.Then add the entire oil quantity. Mix (shake) the fuelmixture. Fill the remaining quantity of gasoline.

• Mix (shake) the fuel mixture carefully before filling in themachine‘s fuel tank.

• Do not mix more than max. one month’s supply of fuel.• If the machine is not used for a long period of time, the fuel

tank should be emptied and cleaned.• This engine is certified to operate on unleaded gasoline.

Min. 3 m(10 ft)

Two-stroke oil

• For the best results use HUSQVARNA two-stroke oil,which has been specially developed for HUSQVARNA’ssmall, two-stroke engines. Mixing ratio 1:50 (2%).

• Never use two-stroke oil intended for water cooled outboardmotors, so-called outboard motor oil.

• Never use oil intended for four-stroke engines.

Gasoline

NOTE!Always use an oil-mixedquality gasoline (at least 87octane). If your machine isequipped with a catalyticconverter, ( an unleaded,oil mixed quality gasolineshould always be used. Aleaded gasoline will destroythe catalytic converter.

• This engine is certified tooperate on unleadedgasoline.

• The lowest recommendedoctane rating is 87. If yourun the engine on loweroctane rating than 87 so-called “knocking“ canoccur. This leads to anincreased enginetemperature, which canresult in a serious enginebreakdown.

• When working atcontinuous high revs ahigher octane rating isrecommended.

MAINTENANCE

CarburetorYour Husqvarna product has been designed andmanufactured to specifications that reduce harmfulemissions.After your unit has been run 8-10 tanks of fuel the enginehas broken in. To ensure that your unit is at peakperformance and producing the least amount of harmfulemissions after break in, have your authorized servicingdealer, who has a revolution counter at his disposal, to adjustyour carburetor for optimum operating conditions.

Basic setting• The carburetor is set to its basic setting when test run at the

factory. The basic setting is richer than the optimal settingand should be kept during the machine’s first workinghours. Thereafter the carburetor should be finely adjusted.Fine adjustment should be carried out by a skilledtechnician.

NOTE! If the cutting attachment rotates/moves while theengine is idling the T-screw should be turned anti-clockwiseuntil the cutting attachment stops.Recommended idling speed is: 2 700 rpm.Recommended max. speed: See “technical data”.

Operation• The carburetor governs

the engine’s speed via thethrottle. Air/fuel is mixedin the carburetor. Theair/fuel mixture isadjustable. To takeadvantage of the engine’soptimal output theadjustment must becorrect.

• The setting of thecarburetor means thatthe engine is adapted tolocal conditions, forexample, the climate,altitude, gasoline and thetype of 2-stroke oil.

• The carburetor is equipped with three adjustment possibili-ties:H = High speed needleL = Low speed needleT = Idle speed adjuster screw

• The fuel quantity in relation to the air flow permitted bythe throttle opening is adjusted using the L and H-needles.Turning the needles clockwise gives a leaner fuel mixture(less fuel) and turning them anti-clockwise gives a richerfuel mixture (more fuel). A leaner mixture gives high revswhile a richer mixture give less revs.

• The T-screw regulates the position of the throttle while theengine is idling. Turning the screw clockwise gives a higheridling speed while turning it anti-clockwise gives a loweridling speed.

WARNING!The blades must be fitted before thehedge trimmer is started, otherwise theclutch can become loose and causepersonal injury.

WARNING!If the idling speed cannot be adjusted sothat the cutting attachment stops,contact your service workshop. Do notuse the machine until it has beencorrectly adjusted or repaired.

!

H L T

T

Adjusting the idle speed, TAdjust the idling speed withthe screw T, if it is necessaryto readjust. First turn theidle speed adjusting screw Tclockwise until the cuttingattachment starts to rotate/move.Then turn, counter-clockwise until the cuttingattachment stops. A correctlyadjusted idle speed settingoccurs when the engine runssmoothly in every position.It should also be goodmargin to the rpm when thecutting attachment starts tomove.CAUTION! Contact your servicing dealer, if the idle speedsetting cannot be adjusted so that the cutting attachmentstops. Do not use the machine until it has been properlyadjusted or repaired.

Correctly adjusted carburetorA correctly adjusted carburetor means that the machineaccelerates without hesitation and the machine 4-cycles a littleat max speed. Furthermore, the cutting attachment must notrotate/move at idling. A too lean adjusted low speed needle Lmay cause starting difficulties and bad acceleration.A too lean adjusted high speed needle H gives lower power =less capacity, bad acceleration and/or damage to the engine.A too rich adjustment of the two speed needles L and H givesacceleration problems or too low working speed.

Cooling system

To maintain as low opera-ting temperature as possiblethe engine is equipped witha cooling system.

The cooling system consistsof:1. An air intake on the

starter unit.2. Cooling fins on the

flywheel.3. Cooling fins on the

cylinder4. Cylinder cover (leads

cold air onto the cylin-der).

Clean the cooling systemusing a brush at least once aweek, in difficult conditionsmore often.

A dirty or blocked cooling system leads to the engineoverheating resulting in damage to the cylinder and piston.

Muffler

NOTE!Some mufflers are fitted with a catalytic converter. See“Technical data” to see whether you clearing saw is fitted with acatalytic converter.

The muffler is designed todampen the noise level andto direct the exhaust fumesaway from the user. Theexhaust fumes are hot andcan contain sparks, whichcan result in fire if theexhaust fumes are directedtowards a dry andinflammable material. Somemufflers are equipped with aspecial spark arrest screen. Ifyour machine is fitted withthis type of screen it shouldbe cleaned regularly. This isdone using a wire brush. Onmufflers without a catalyticconverter the screen shouldbe cleaned weekly, orreplaced if necessary. Onmufflers fitted with acatalytic converter thescreen should be checkedand cleaned monthly. If thescreen is damaged it shouldbe replaced. If the screen isfrequently blocked, this canbe a sign that the functionof the catalytic converter isimpaired. Contact yourdealer to inspect the muffler.A blocked screen will causethe engine to overheatresulting in damage to thecylinder and piston. Also seeunder “Maintenance”.

NOTE!Never use a machine with adefective muffler.

WARNING!Mufflers fitted with catalytic convertersbecome extremely hot during use andafter stopping. This also applies at idlingspeeds. Contact can result in burns tothe skin. Be observant to the risk of fire!
