To reducethe risk of damage to property, alsomaintain this distance from other objects(vehicles, windows).The correct engine idle speed isimportant to ensure that the cuttingattachment stops rotating when you letgo of the throttle trigger.Trimmer and Brushcutter Safety ManualTake special care in slippery conditions– damp, snow, ice, on slopes or unevenground.Watch out for obstacles: Roots, treestumps or holes which could cause youto trip or stumble.Always stand on the ground whileworking, never on a ladder, workplatform or any other insecure support.Be particularly alert and cautious whenwearing hearing protection becauseyour ability to hear warnings (shouts,alarms, etc.) is restricted.To reduce the risk of accidents, take abreak in good time to avoid tiredness orexhaustion.Work calmly and carefully – in daylightconditions and only when visibility isgood. Stay alert so as not to endangerothers.Your power tool producestoxic exhaust fumes assoon as the engine isrunning. These fumesmay be colorless andodorless and containunburned hydrocarbonsand benzol. Never runthe engine indoors or inpoorly ventilated locations, even if your modelis equipped with a catalytic converter.To reduce the risk of serious or fatalinjury from breathing toxic fumes,ensure proper ventilation when workingin trenches, hollows or other confinedlocations.To reduce the risk of accidents, stopwork immediately in the event ofnausea, headache, visual disturbances(e.g. reduced field of vision), problemswith hearing, dizziness, deterioration inability to concentrate. Apart from otherpossibilities, these symptoms may becaused by an excessively highconcentration of exhaust gases in thework area.Operate your power tool so that itproduces a minimum of noise andemissions – do not run the engineunnecessarily, accelerate the engineonly when working.To reduce the risk of fire, do not smokewhile operating or standing near yourpower tool. Note that combustible fuelvapor may escape from the fuel system.The dusts, vapor and smoke producedduring operation may be dangerous tohealth. If the work area is very dusty orsmoky, wear a respirator.If your power tool is subjected tounusually high loads for which it was notdesigned (e.g. heavy impact or a fall),always check that it is in good conditionbefore continuing work – see also"Before Starting".Check the fuel system in particular forleaks and make sure the safety devicesare working properly. Do not continueoperating your power tool if it isdamaged. In case of doubt, have the unitchecked by your servicing dealer.5

EnglishDo not operate your power tool in thestarting throttle position – engine speedcannot be controlled in this position.To reduce the riskof injuryfromthrown objects,never operate theunit without theproper deflector forthe type of cuttingattachment beingused.Inspect the work area:Stones, pieces of metalor other solid objects canbe thrown and cause personal injury or damagethe cutting attachmentand property (e.g. parkedvehicles, windows).Special care must be taken whenworking in difficult, over-grown terrain.When cutting high scrub, under bushesand hedges: Keep cutting attachment atminimum height of 15 cm to avoidharming small animals.Always shut off the engine beforeleaving the unit unattended.Check the cutting attachment at regularshort intervals during operation orimmediately if there is a noticeablechange in cutting behavior:–Turn off the engine. Hold the unitfirmly and wait for the cuttingattachment to come to a standstill.–Check condition and tightness, lookfor cracks.6–Check sharpness.–Replace damaged or dull cuttingattachments immediately, even ifthey have only superficial cracks.Clean grass and plant residue off thecutting attachment mounting at regularintervals – remove any build up ofmaterial from the cutting attachment anddeflector.To reduce the risk of injury, shut off theengine before replacing the cuttingattachment.Do not continue using or attempt torepair damaged or cracked cuttingattachments by welding, straightening ormodifying the shape (out of balance).This may cause parts of the cuttingattachment to come off and hit theoperator or bystanders at high speedand result in serious or fatal injuries.When using mowing headsEquip the deflector with the additionalcomponents specified in the instructionmanual.Use only the deflector with properlymounted line limiting blade to ensure themowing lines are automatically trimmedto the approved length.To reduce the risk of injury, always turnoff the engine before adjusting the nylonline of manually adjustable mowingheadsUsing the unit with over-long nyloncutting lines reduces the motor'soperating speed. The clutch then slipscontinuously and this causesoverheating and damage to importantcomponents (e.g. clutch, polymerhousing components) – and this canincrease the risk of injury from thecutting attachment rotating while theengine is idling.When using metal cutting attachmentsSTIHL recommends the use of originalSTIHL metal cutting attachments. Theyare specifically designed to match yourmodel and meet your performancerequirements.Metal cutting attachments rotate at veryhigh speed. The forces that occur act onthe machine, the attachment and thematerial being cut.Sharpen metal cutting attachmentsregularly as specified.Unevenly sharpened metal cuttingattachments cause out-of-balancewhich can impose extremely high loadson the machine and increase the risk ofbreakage.Dull or improperly sharpened cuttingedges can put a higher load on thecutting attachment and increase the riskof injuryfrom cracked or broken parts.Inspect metal cutting attachments forcracks or warping after every contactwith hard objects (e.g. stones, rocks,pieces of metal). To reduce the risk ofinjury, remove burrs and other visiblebuild-ups of material (use a file) becausethey may become detached and bethrown at high speed during operation.To reduce the above-mentioned riskswhen using a metal cutting attachment,never use a metal cutting attachmentwith a diameter larger than specified. Itmust not be too heavy. It must beTrimmer and Brushcutter Safety Manual

Englishmanufactured from materials ofadequate quality and its geometry mustbe correct (shape, thickness).To reduce the risk of injury, a metalcutting attachment not manufactured bySTIHL must not be heavier, thicker,have a different shape or a diameterlarger than the largest metal cuttingattachment approved by STIHL for thispower tool model.VibrationsProlonged use of the power tool mayresult in vibration-induced circulationproblems in the hands (whitefingerdisease).No general recommendation can begiven for the length of usage because itdepends on several factors.The period of usage is prolonged by:–Hand protection (wearing warmgloves)–Work breaksThe period of usage is shortened by:–Any personal tendency to sufferfrom poor circulation (symptoms:frequently cold fingers, tinglingsensations).–Low outside temperatures.–The force with which the handlesare held (a tight grip restrictscirculation).Continual and regular users shouldmonitor closely the condition of theirhands and fingers. If any of the abovesymptoms appear (e.g. tinglingsensation in fingers), seek medicaladvice.Trimmer and Brushcutter Safety ManualMaintenance and RepairsService the machine regularly.
