English / USA THE USE OF THE CLEARING SAW Transporting the clearing saw !Warning! Always turn off the engine and make sure the cutting attachment has stopped before putting a clearing saw down. When transporting your clearing saw in a vehicle, properly secure it to prevent turnover, fuel spillage and damage to the clearing saw. Keep metal cutting tools covered with the transport guard (optional accessory). Preparation for the use of the clearing saw Adjust carrying harness and hand grip to suit your size before starting work. The machine should be properly balanced as specified in your owner's manual for proper control and less fatigue in operation. Always check your clearing saw for proper condition and operation before starting, particularly the throttle trigger, throttle trigger interlock (if applicable), stopswitch, cutting tool, deflector and harness. A B Arrows on the deflector (A) and stop (B) show the correct direction of rotation of the cutting tool. The throttle trigger must move freely and always spring back to the idle position. The cutting tool must be properly tightened and in safe operating condition. Inspect for loose parts (nuts, screws, etc.) and for cracked, bent, warped or damaged blades. 000BA007 KN 000BA006 KN Fueling Your STIHL clearing saw uses an oilgasoline mixture for fuel (see the chapter on "Fuel" of your owner's manual). !Warning! 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 or clearing saw. Fueling Instructions !Warning! Fuel your clearing saw in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refueling.
