SAFETY GENERAL PRECAUTIONS Do not weld or use a cutting torch to cut any pipes or tubes that contain flammable liquids. Fire caused by accumulation of flammable material. Remove any dry leaves, chips, pieces of paper, dust, or any other flammable materials accumulated or affixed around the engine, exhaust manifold, muffler, or battery, or inside the undercovers. Fire coming from electric wiring Short circuits in the electrical system can cause fire. Always keep electric wiring connections clean and securely tightened. Check the wiring every day for looseness or damage. Tighten any loose connectors or wiring clamps. Repair or replace any damaged wiring.
Fire coming from hydraulic line Check that all the hose and tube clamps, guards, and cushions are securely fixed in position. If they are loose, they may vibrate during operation and rub against other parts. This may lead to damage to the hoses, and cause high-pressure oil to spurt out, leading to fire damage or serious injury. Explosion caused by lighting equipment When checking fuel, oil, battery electrolyte, window washer fluid, or coolant, use explosion-proof lighting. If you do not use explosion-proof lighting, there is a hazard of serious injury or damage caused by explo- sion. When taking the electrical power for the lighting from the machine, follow the instructions in this manual.
ACTION IF FIRE OCCURS If a fire occurs, escape from the machine as follows. Turn the starting switch OFF and stop the engine. Use the handrails and steps to get off the machine. WINDOW WASHER LIQUID Use an ethyl alcohol base washer liquid. Methyl alcohol base washer liquid may irritate your eyes, so do not use it. PRECAUTIONS WHEN USING ROPS Install ROPS when working in places where there is danger of falling rocks, such as in mines and quarries, or in places where there is danger of rolling over. If ROPS is installed, do not remove it when operating the machine. ROPS is installed to protect the operator when machine rolls over.
When machine rolls over, ROPS supports its weight and absorbs its impact energy. If ROPS is modified, its strength may lower. When modify- ing it, consult your Komatsu distributor. If ROPS is deformed by falling objects or by rolling over, its strength lowers and its design functions cannot be maintained. In this case, be sure to ask your Komatsu distributor about repair method. 2-13
