6DIHW\ 3UHFDXWLRQV DQG :RUNLQJ 7HFKQLTXHV :DUQLQJ Because a trimmer is a high-speed, fast-cutting power tool, special safety precautions must be observed to reduce the risk of personal injury. It is important that you read, fully understand and observe the following safety precautions and warnings. Read the owner’s manual and the safety instructions periodically. Careless or improper use of any trimmer may cause serious or fatal injury. Have your STIHL dealer show you how to operate your trimmer.
ment of whitefinger disease. In order to reduce the risk of whitefinger disease and carpal tunnel syndrome, please note the following: - - - Most STIHL power tools are available with an anti-vibration ("AV") system designed to reduce the transmission of vibrations created by the engine to the operator’s hands. An AV system is recommended for those persons using power tools on a regular or sustained basis. Wear gloves and keep your hands warm. Keep the AV system well maintained.

Only attachments supplied by STIHL or expressly approved by STIHL for use with the specific STIHL trimmer models are authorized.
:DUQLQJ Gasoline is an extremely flammable fuel. If spilled and ignited by a spark or other ignition source, it can cause fire and serious burn injury or property damage. Use extreme caution when handling gasoline or fuel mix. Do not smoke or bring any fire or flame near the fuel. )XHOLQJ ,QVWUXFWLRQV Fuel your trimmer in well-ventilated areas, outdoors.
:DUQLQJ To reduce the risk of injury from loss of control, be absolutely sure that the cutting tool is clear of you and all other obstructions and objects, including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage and turn the cutting tool. :DUQLQJ When you pull the starter grip, don’t wrap the starter rope around your hand. Do not allow the grip to snap back, but guide the starter rope to rewind it properly.
002BA057 KN 002BA056 KN Always hold the trimmer firmly with both hands. Wrap your fingers tightly around the handles, keeping the handles cradled between your thumb and forefinger. Keep your hands in this position, to have your trimmer under control at all times. Make sure your trimmer handles and grip are in good condition and free of moisture, pitch, oil or grease. :DUQLQJ Never attempt to operate any trimmer with one hand.
:DUQLQJ Keep hands and feet away from cutting tool. Never touch a rotating cutting tool with your hand or any part of your body. It continues to rotate for a short period after the throttle trigger is released (flywheel effect).
:DUQLQJ Never test the ignition system with ignition wire terminal removed from spark plug or with unseated spark plug, since uncontained sparking may cause a fire. :DUQLQJ To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be attached.

)XHO 0L[ Your two-stroke engine requires a mixture of brand-name gasoline and quality two-stroke engine oil with the FODVVLILFDWLRQ 7& Use regular branded unleaded gasoline with a minimum octane rating of 89 ROZ. If the octane rating of the regular grade gasoline in your area is lower, use premium unleaded fuel. Fuel with a lower octane rating may result in preignition (causing “pinging”) which is accompanied by an increase in engine temperature.

*HQHUDO 1RWHV RQ 2SHUDWLRQ &KHFNLQJ 6SDUN 3OXJ 'XULQJ EUHDN LQ SHULRG If engine is down on power, difficult to start or runs poorly at idling speed, first check the spark plug. A factory new machine should not be run at high revs (full throttle off load) for the first three tank fillings. This avoids unnecessary high loads during the break-in period. • • • As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period.
