OC60-E2, OC95-E2, WSM SAFETY INSTRUCTIONS 2 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 safety equipment appropriate to the job. Use tools appropriate to the work. Makeshift 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 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. Wear a suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises. 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. Make sure that no fuel has been spilled on the engine. 0000001389E 0000001390E

OC60-E2, OC95-E2, WSM SAFETY INSTRUCTIONS 3 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. 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. 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. 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. 0000001391E 0000001393E 0000001392E 0000001394E
