81700·82100·82400 WSM.11770 SAFETY INSTRUCTIONS (7) If the engine must be running to do same work, make sure the area is well ventilated. Never run the engine in a closed area. The exhaust gas contains poisonous carbon monoxide. (8) Do not touch the rotating or hot parts while the engine is running. (9) Fuel is extremely flammable and explosive under certain conditions. Do not smoke or allow flames or sparks in your working area. (10) To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable first and connect it last. (11) Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, clothing and cause blindness if splashed into eyes. Keep electrolyte away from eyes, hands and clothing. If you spill electrolyte on yourself, flush with water, and get medical attention immediately. (12) Battery gas can explode. Keep sparks and open flame away from the top of battery, especially when charging the battery. (13) Never remove the radiator cap while the engine is running, or immediately after stopping. Otherwise, hot water will spout out from radiator. Wait for more than ten minutes to cool the radiator, before removing the cap. (14) Escaping fluid (fuel or hydraulic oil) under pressure can penetrate the skin causing serious injury. Relieve pressure before disconnecting hydraulic or fuel lines. Tighten all connections before applying pressure. (15) Do not start the engine by shorting across starter terminals. (16) Unauthorized modifications to the machine may impair the function and I or safety and affect machine life. (17) Do not alter or remove any part of machine safety system. (18) Keep a first aid kit and fire extinguisher handy at all times. (19) Be sure to chock the wheels to prevent accident during servicing the machine. 2
