For easy control of machine during cutting work. Switches the engine’s ignition system off and stops the running engine. Must be depressed before the throttle trigger can be activated. The grip of the pull starter, which is the device to start the engine. Connects the spark plug to the ignition wire.
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.
STIHL for use with the specific STIHL trimmer models are authorized. Although certain un- authorized attachments are useable for the STIHL trimmer, their use may, in fact, be extremely dangerous. Improper use of any trimmer can cause serious or fatal personal injury.
In order to reduce risk of fuel spillage and fire, tighten fuel cap by hand with as much force as possible. The screwdriver end of the STIHL combination wrench or other similar tool can be used as an aid for tightening slotted fuel caps.
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.
Always hold the trimmer firmly with both hands. Wrap your fingers tightly around the handles, keeping the handles cradled between your thumb and fore- finger. 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.
For directions on how to adjust idle speed, see the appropriate section of your owner’s manual. If you cannot set the correct idle speed, have your STIHL dealer check your trimmer and make proper adjustments and repairs Use only identical STIHL replacement parts for maintenance and repair.
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.) A loose connection between...

Exhaust emissions are controlled by the design of the fundamental engine parameters and components (e.g. carburetion, ignition, timing and valve or port timing) without the addition of any major hardware. Your carburetor is preset at the factory. This is the optimum setting under the barometric pressure and climatic conditions at the factory and is suitable for most operating sites.
Fit a new spark plug after approx. 50 operating hours - or earlier if the electrodes are badly eroded. To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL (see “Specifications”).
