English Fuel Your STIHL chain saw uses an oilgasoline mixture for fuel (see the chapter on "Fuel" of your instruction 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 the chain saw. Note that combustible fuel vapor may escape from the fuel system. Fueling Instructions WARNING Fuel your chain saw in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refueling. Gasoline vapor pressure may build up inside the fuel tank depending on the fuel used, the weather conditions and the tank venting system. In order to reduce the risk of burns and other personal injury from escaping gas vapor and fumes, remove the fuel filler cap on your chain saw carefully so as to allow any pressure build-up in the tank to release slowly. Slowly turn the filler cap left to the vent position of the cap at about 1/2 turn where the cap is held in place by the thread. Once the fumes have been relieved, turn the cap further until the cap can be removed from the tank thread. Never remove the fuel filler cap by quickly turning it to the full open position without letting it vent out any vapor/pressure build-up at the 1/2 position. Never remove the fuel filler cap while the engine is running. Select bare ground for fueling and move at least 10 feet (3 m) from the fueling spot before starting the engine. Wipe off any spilled fuel before starting your chain saw. WARNING Check for fuel leakage while refueling and during operation. If fuel leakage is found, do not start or run the engine until the leak is fixed and any spilled fuel has been wiped away. Take care not to get fuel on your clothing. If this happens, change your clothing immediately. Different models may be equipped with different fuel caps. Screw Cap WARNING Unit vibrations can cause an improperly tightened fuel filler cap to loosen or come off and spill quantities of fuel. In order to reduce the risk of fuel spillage and fire, tighten the fuel filler cap by hand as securely as possible. See also the "Fueling" chapter in your Instruction Manual for additional information. Before Operation Take off the chain guard (scabbard) and inspect the chain saw for proper condition and operation. (See the maintenance chart near the end of the instruction manual.) WARNING Always check your chain saw for proper condition and operation before starting, particularly the throttle trigger, throttle trigger lockout, stop switch and cutting attachment. The throttle trigger must move freely and always spring back to the idle position. The Master Control Lever / stop switch must move easily to STOP, 0 or †. Never attempt to modify the controls or safety devices. WARNING Check fuel system for leaks, especially the visible parts, e.g., filler cap, hose connections, manual fuel pump (only for chain saws equipped with a manual fuel pump). Do not start the engine if there 6 MS 170, MS 170 C, MS 180, MS 180 C
