SAFETY INSTRUCTIONS
Cutting equipment Sharpening thegrass blade
• See the cuttingequipment’s packaging forcorrect filing instructions.
• The blades are sharpenedusing a single cut flat file.
• Sharpen all edges equallyto maintain the balance ofthe blade.
Trimmer head
• Only use a trimmer headand trimmer cord that isrecommended. Thesehave been tested by themanufacturer to suit aparticular engine size.This is especiallyimportant when a fullyautomatic trimmer headis used. Only use thecutting equipment werecommend! See chapter“Technical data“.
!
WARNING!Always stop the engine before startingwork on any part of the cutting equipment.This continues to rotate even after thethrottle has been released. Ensure that thecutting equipment has stopped completelyand remove the cable from the spark plugbefore you start to work on it.
IMPORTANT INFORMATION
Always ensure the trimmer cord is wound tightlyand evenly around the drum, otherwise harmfulvibrations will occur.
• Generally smaller machines require a small trimmer headand vice versa. This is because when clearing using a cordthe engine must throw out the cord radially from thetrimmer head and also meet resistance from the grass beingcleared.
• The length of the cord is also important. A longer cordrequires greater engine power than a shorter cord of thesame diameter.
• Make sure the knife positioned on the trimmer guard isintact. This is used to cut the cord to the correct length.
• To increase the life of the cord it can be soaked in water fora few days. This will make the line tougher and it will keeplonger.
Sharpening theclearing blade
• See the cuttingequipment’s packaging forcorrect filing instructions.
• A correctly sharpenedblade is a prerequisite forworking efficiently and toavoid unnecessary wear tothe blade and clearing saw.
• Make sure that the blade iswell supported when youuse the file. Use a 5,5 mmround file with a fileholder.
• The sharpening angle is15°. Every other tooth issharpened to the right andthe intermediate tooth tothe left. When the bladehas been heavily pitted bystones the upper side ofthe teeth can, inexceptional cases, need tobe dressed using a flat file.In such cases this takesplace before sharpeningwith the round file.Dressing the top side mustbe carried out equally forall teeth.
• Adjust the setting. Thisshould be 1 mm.
IMPORTANT INFORMATION
The section describes how through correct mainte-nance and through using the right type of cuttingequipment you can reduce the machine‘s tendency tokickback, obtain maximum clearing capacity andincrease the service life of the cutting equipment.
• Only use the cutting and guard equipment werecommend! See chapter “Technical data“.
• Refer to the instructions for the cuttingequipment for the correct winding of cordand for the selection of the right cord diameter.
• Keep the blade’s teeht well and correctlysharpened! Follow our recommendations. Alsorefer to the instructions on the blade packaging.
• Maintain the correct setting. Follow our instruc-tions and use the recommended filing gauge.
WARNING!Incorrect cutting equipment or anincorrectly sharpened blade increasesthe risk of kickback.

SAFETY INSTRUCTIONS
Adjusting the harness and clearing saw
Designations
• Use a saw blade forcutting woody growthwith thin stems.
• Use a grass knife or grassblade for clearing grass.
• Use a trimmer head orplastic blades for lighterclearing work, forexample along verges oraround trees.
Basic clearing techniques
• Always drop to idling speed after each working operation.Longer periods running at full throttle without loading theengine (that is without resistance, which the engine feelsfrom the cutting equipment when trimming) can lead toserious engine damage.
!
WARNING!Sometimes branches, grass or wood canget caught between the guard and cuttingequipment. Always stop the engine whencleaning.
Quick releaseOn the front is an easilyaccessible, quick releasecatch. Use this if the engineshould catch fire or in anyother emergency situationwhen you quickly need totake off the harness andmachine.
Even load on theshouldersA well-adjusted harness andclearing saw significantlyfacilitates working. Adjustthe harness for the bestworking position. Tensionthe side straps so that theweight is evenly distributedacross the shoulders.
Correct heightAdjust the support strap sothat the cutting attachmentis parallel to the ground.
Correct balanceThe cutting attachmentshould rest lightly on theground. If you use a sawblade it should balanceabout 10 cm above theground to prevent contactwith stones and the like.Adjust the position of thesupport strap attachmentring to balance the clearingsaw correctly.
!
WARNING!When working with the clearing saw itshould always be hooked in the harness. Ifthis is not done, you cannot control theclearing saw safely and this can result ininjury to yourself or someone else. Neveruse a harness with a defective quickrelease catch.

SAFETY INSTRUCTIONS
Clearing‘s ABC
A. Always use the correct equipment.B. Always have well adjusted equipment.C. Follow the safety instructions.D. Organise the work well.E. Always use full throttle when applying the blade.F. Always use a sharp blade.G. Avoid stones.
!
WARNING!Avoid cutting in the cutting regionbetween 12 and 3 o‘clock on the blade.Kickback can occur due to the blade‘srotation speed in this area of the bladewhen applied on thick stems.
Working methods• Before you start clearing,
check the clearing area, itscondition, slopes, if thereare stones, pits, etc.
• On sloping ground thepathway should runparallel to the slope. It isfar easier to work along aslope then up and down aslope.
• The pathway should beplanned so that you avoidgoing over ditches or otherobstacles.
Brush cuttingusing the sawblade
• Cut through thin stemsand brush. Swing theblade sideways in a sawingmotion.
• Avoid cutting in thecutting region between 12and 3 o‘clock on theblade. 12

!
WARNING!Neither the user of the tool or anyone elsemay attempt to remove the cut materialwhile the engine is running or with theblade rotating as this can result in seriousinjury.Stop the engine and blade before youremove material that has wound around theblade as otherwise there is a risk of injury.The bevel gear unit can get hot during useand may remain so for a while afterwards.There is a risk of slight burns if you touchit.
!
WARNING!Beware of thrown objects. Always wear eyeprotection. Never lean over the guard.Stones, rubbish etc. can be thrown up intothe eyes resulting in blindness or otherserious injury.Keep unauthorised persons at a distance.Children, animals, onlookers and helpersshould be outside the safety zone of 15meters (50 feet). Stop the machineimmediately if anyone approaches.
• A blade is used for alltypes of high or thickgrass.
• The grass is cut downwith a sideways, swingingmovement, where themovement from right-to-left is the clearing strokeand the movement fromleft-to-right is the returnstroke. Let the blade workon the left-hand side(between 8 and 12o’clock).
Grass clearing using a grass blade
• If the blade is angled to the left when clearing the grass willcollect in a line, which makes collection easier, e.g. whenraking.
• Try to work rhythmically. Stand firmly with your feet apart.Move forward after the return stroke and stand firmly again.
• Let the support cup rest lightly against the ground. It is usedto protect the blade from hitting the ground.
• Reduce the risk of material wrapping around the blade byfollowing these instructions:a) Always work at full throttle.b) Avoid the previously cut material during the returnstroke.
• Stop the engine and remove the brushcutter from theharness before you start to gather the cut material.

SAFETY INSTRUCTIONS
Grass clearingusing the trimmerhead and plasticblades.
• Hold the trimmer headjust above the ground atan angle. It is the end ofthe cord that carries outthe work. Let the cordwork at its own pace.Do not press the cordinto the area to be cut.
• The cord can easilyremove grass and weedsup against walls, fences,trees and borders,however, it can alsodamage sensitive bark ontrees and bushes anddamage fence posts.
• Reduce the risk ofdamaging plants byshortening the cord to10-12 cm and reducingthe engine speed.
Clearing• The clearing technique
removes all unwantedvegetation. Keep thetrimmer head just abovethe ground and tilt it.Let the end of the cordstrike the ground aroundtrees, posts, statues andthe like. NOTE! Thistechnique increases thewear on the cord.
• The cord wears quickerand must be fed forwardmore often whenworking against stones,brick, concrete, metalfences, etc. than whencoming into contactwith trees and woodenfences.
• When trimming andclearing you should useless than full throttle sothat the cord lasts longerand to reduce the wearon the trimmer head.
Trimming• The trimmer is ideal to
cut grass that is difficultto reach using a normallawn mower. Keep thecord parallel to theground when cutting.Avoid pressing thetrimmer head against theground as this can ruinthe lawn and damage thetool.
• Do not allow thetrimmer head toconstantly come intocontact with the groundduring normal cuttingprocedures. Constantcontact can cause damageand wear to the trimmerhead.
Sweeping• The rotating cord‘s
fanning effect can beused for quick and easycleaning. Hold the cordparallel to and above thearea to be swept andmove the trimmer fromside to side.
• When cutting andsweeping you should usefull throttle to obtain thebest results.

START AND STOP
Control before starting
For reasons of safety followthese recommendations!
• Check the blade to ensurethat no cracks have formedat the bottom of the teethor by the centre hole. Themost common reason whycracks are formed is thatsharp corners have beenformed at the bottom ofthe teeth while sharpeningor that the blade has beenused with dull teeth.Discard a blade if cracksare found.
• Check that the supportflange is not cracked due tofatigue or due to beingtightened too much.Discard the support flangeif it is cracked.
• Ensure the locking nut hasnot lost its captive force.The nut lock should have alocking force of at least 1.5Nm. The tighteningtorque of the locking nutshould be 35-50 Nm.
• Check that the guard is notdamaged or cracked.Replace the guard if it isexposed to impact or iscracked.
• Check that the trimmerhead and spray guard arenot damaged or cracked.Replace the trimmer heador spray guard if they areexposed to impact or arecracked.

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.
Functioning• The carburetor governs the
engine speed via thethrottle trigger. In thecarburetor, air/fuel ismixed. This air/fuelmixture is adjustable. Ifyou want to takeadvantage of themaximum output of theengine, the setting must becorret.
• The setting of thecarburetor means that theengine is adjusted to localconditions, for exampleclimate, altitude, gasolineand type of two-stroke oil.
• The carburetor has threeadjustment possibilities:L= Low speed needleH= High speedadjustment screwT= Idle speed adjustmentscrew
Basic setting• The carburetor is set to its basic setting when test run at the
factory. The basic setting should be kept during themachine‘s first working hours. Thereafter the carburetorshould be finely adjusted. Fine adjustment should be carriedout by a skilled technician.
NOTE! If the cutting attachment rotates/moves in the idlingposition, turn the idling speed screw counter-clockwise untilthe blade stops.Rec. idling speed: 2 700 rpm.
Recommended max. speed: See “Technical Data” .
MAINTENANCE
!
WARNING!The complete clutch cover with shaft mustbe fitted before the machine is started,otherwise the clutch can become looseand cause personal injury.
!
WARNING!Contact your servicing dealer, if the idlespeed setting cannot be adjusted sothat the cutting attachment stops. Donot use the machine until it has beenproperly adjusted or repaired.
Fine adjustment• When the machine has been ”run-in” the carburetor should
be finely adjusted. The fine adjustment should be carriedout by qualified person. First adjust the L-jet, then theidling screw T and then the H-jet.
Conditions• Before any adjustments are made the airfilter should be clean
and the airfilter cover fitted. Adjusting the carburetor whilea dirty airfilter is in use will result in a leaner mixture whenthe filter is finally cleaned. This can give rise to seriousengine damage.
• Carefully turn the L and H needle to the mid point betweenfully turned in and fully turned out.
• Do not attempt to adjust the needles beyond the stops asdamage can occur.
• Now start the machine according to the starting instructionsand run it warm for 10 minutes.
NOTE! If the cutting attachment rotates/moves the T screwshould be turned anti-clockwise until the cutting attachmentstops.
Low speed needle LTry to find the highest idlingspeed, turning the low speedneedle L clockwiserespectively counter-clockwise. When the highestspeed has been found, turnthe low speed needle L 1/4turn counter-clockwise.NOTE! If the cuttingattachment rotates/moves inthe idling position, turn theidling speed screw Tcounter-clockwise until thecutting attachment stops.
• The idling speed screw T regulates the position of thethrottle lever in the idling speed position. Turn the idlingspeed screw clockwise gives a higher idling speed, turn itcounter-clockwise a lower idling speed.
• The fuel quantity requiredin proportion to theairflow the throttle triggerlevel allows is adjusted bymeans of the L- and H-needles. Turning theneedles clockwise gives aleaner fuel mixture (lessfuel), turning themcounter-clockwise gives aricher fuel mixture (morefuel). A lean mixture giveshigher rpms and a rich onelower rpms.

24 – English
Final setting of the idling 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 torotate/move.
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.
MAINTENANCE
High speed needleHThe high speed needle affectsthe machine’s power, speed,temperature and fuelconsumption. A too leanadjustment on the highspeed needle H (the highspeed needle H is screwed intoo much) gives a too highspeed resulting in enginedamage. Do not allow theengine to run at full speedfor more than 10 seconds.Apply full throttle and turnthe high speed needle Hslowly anticlockwise untilthe engine runs unevenly.The high speed needle H isthen turned slowly clockwisea little until the engine runssmoothly.Note the engine should berun unloaded whenadjusting the high speedneedle. Therefore dismantlethe cutting equipment, nut,support flange and disc drive
H
before adjusting the high speed needle. The high speed needleis adjusted correctly when the machine ‘splatters’ a little . If themachine smokes heavily at the same time as it ‘splatters’ heavilythe adjustment is too rich.
NOTE! For optimum setting of the carburetor, contact aqualified servicing dealer who has a revolution counter at hisdisposal.
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.
Adjusting the start throttle speed
The correct start throttlespeed is set by means of anadjuster on the rear of thehandle next to the cable. Usethis screw (4 mm Allenscrew) to increase ordecrease the start throttlespeed.
Proceed as follows:
1. Run the machine atidle.
2. Press the start throttlelock as described underthe heading ”Startingand stopping”.
3. If the start throttle speed is too low (below 4000 rpm),turn the adjuster screw A clockwise until the cuttingattachment starts to rotate. Then turn A clockwise afurther 1/2 turn.
4. If the start throttle speed is too high, turn the adjusterscrew A anticlockwise until the cutting attachment stops.Then turn adjuster screw A clockwise a further 1/2 turn.

MAINTENANCE
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 cylinder).
Clean the cooling systemusing a brush at least once aweek, in difficult conditionsmore often.A dirty or blocked coolingsystem leads to the engineoverheating resulting indamage to the cylinder andpiston.
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!

Spark plug
The condition of the sparkplug is affected by:• An incorrect carburetor
setting.• An incorrect fuel
mixture (too much orfaulty oil).
• A dirty air filter.
These factors causedeposits on the spark plugelectrode that may result inmalfunction or startingdifficulties.If the machine is low on power, difficult to start or runspoorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time checkthat the electrode gap is 0.5 mm. The spark plug should bechanged after about one month of operation or earlier ifnecessary.NOTE! Always use the recommended type of spark plug. Anincorrect spark plug can damage the cylinder/piston.
0,5 mm
Air filter
The air filter should becleaned regularly removingdust and dirt to avoid:• carburetor malfunction• starting problems• reduced engine power• unnecessary wear to
engine parts• abnormal fuel
consumption
Clean the filter after every25 hours or more regularlyif operating conditions areexceptionally dusty.
Cleaning the air filterDismantle the air filtercover and remove the airfilter. Wash in clean, warmsoapy water. Ensure that thefilter is dry before refitting. An air filter used for a long periodof time can never be cleaned completely. Therefore it isnecessary to replace the filter from time to time with a newfilter. A damaged air filter must always be replaced.If the machine is used in dusty conditions the air filtershould be soaked in oil, see the section on “Oiling the airfilter“.
!
WARNING!Always discard a blade that is bent,twisted, cracked, shattered or damaged inany other way. Never attempt to straightena twisted blade for use again. Only useoriginal blades of the prescribed type.
• See the cuttingequipment’s packagingfor correct filinginstructions.
• The blades are sharpenedusing a single cut flat file.
• Sharpen all edges equallyto maintain the balanceof the blade.
Filing the grass blade
WARNING!Always stop the engine before startingwork on any part of the cutting equipment.This continues to rotate even after thethrottle has been released. Ensure that thecutting equipment has stopped completelyand remove the cable from the spark plugbefore you start to work on it.
!
MAINTENANCE
Oiling the air filterAlways use HUSQVARNAfilter oil, order no. 503 4773-01. The filter oilcontains a solvent to make itspread evenly through thefilter. You should thereforeavoid skin contact. Put thefilter in a plastic bag and thepour the filter oil over it.Knead the plastic bag todistribute the oil. Squeezethe excess oil out of the filterinside the plastic bag andpour off the excess beforefitting the filter on themachine. Never use com-mon engine oil. This woulddrain through the filterquite quickly and collect inthe bottom.
