LA1001 . LA 1002' LA1162' LA1251 WSM • + - SAFETY STARTING • Do not start the engine by shorting across starter terminals or bypassing the safety start switch. • Do not alter or remove any part of machine safety system. • Betore starting the engine, make sure that all shift levers are in neutral positions or in disengaged positions. • Never start the engine while standing on ground. Start the engine only trom operator's seat. SAFETY WORKING • Do not work on the machine while under the influence of alcohol, medication, or other substances or while fatigued. • Wear close fitting clothing and satety equipment appropriate to the job. • Use tools appropriate to the work. Markshift tools, parts, and procedures are not recommended. • When servicing is performed together by two or more persons, take care to perform all work safely. • Do not work under the machine that is supported solely by a jack. Always support the machine by safety stands. • Do not touch the rotating or hot parts while the engine is running. • Never remove the radiator cap while the engine is running, or immediately after stopping. Otherwise, hot water will spout out from radiator. Only remove radiator cap when cool enough to touch with bare hands. Slowly loosen the cap to first stop to relieve pressure before removing completely. • 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. AVOID FIRES • Fuel is extremely flammable and explosive under certain conditions. Do not smoke or allow flames or sparks in your working area . • To avoid sparks from an accidental short circuit, always disconnect the battery negative cable first and connect it last. • Battery gas can explode. Keep sparks and open flame away from the top of battery, especially when charging the battery. • Mark sure that no fuel has been spilled on the engine. 2

LA1001 . LA1002· LA1162· LA1251, WSM VENTILATE WORK AREA • If the engine must be running to do some work, make sure the area is well ventilated. Never run the engine in a closed area. The exhaust gas contains poisonous carbon monoxide. PREVENT ACID BURNS • 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. DISPOSE OF FLUIDS PROPERLY • Do not pour fluids into the ground, down a drain, or into a stream, pond, or lake. Observe relevant environmental protection regulations when disposing of oil, fuel, coolant, electrolyte and other harmful waste. PREPARE FOR EMERGENCIES • Keep a first aid kit and fire extinguisher handy at all times. • Keep emergency numbers for doctors, ambulance service, hospital and fire department near your telephone. 3
