Komatsu — Explosion Caused by Lighting Equipment

SAFETY Use well-ventilated areas for adding or storing oil and fuel. Keep oil and fuel in the determined place and do not allow unauthorized persons to enter. When washing parts with oil, use a non-flammable oil. Do not use diesel oil or gasoline. There is danger that they may catch fire. Put greasy rags and other flammable materials into a safe container to maintain safety at the work place. Do not weld or use a cutting torch to cut any pipes or tubes that contain flammable liquids. Move flammable materials to a safe place before doing grinding or welding work on the machine.

Fire Caused by Accumulation of Flammable Material Remove any dry leaves, chips, pieces of paper, coal dust, or any other flammable materials accumulated or affixed around the engine, exhaust manifold, muffler, air cleaner, battery, or inside the undercovers. Operations such as logging, mulching, clearing, and landfill work may cause trash and debris to accumulate on the machine. Remove accumulated trash and debris on a daily basis. Clean the machine after servicing the hydraulic system, engine, or fuel system. Working near burn piles or other open burning may cause airborne sparks or glowing embers to cause a fire on the machine.

Fire Caused by Electrical Wiring Short circuits in the electrical system can cause a fire. Observe the following precautions: Keep all electric wiring connections clean and securely tightened. Check the wiring every day for looseness or damage to the wire insulation. Tighten any loose connectors or wiring clamps. Repair or replace any damaged, pinched, or chaffed wiring. Fire Caused by Piping 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.

There is danger that this may lead to damage to the hoses and cause high-pressure oil to squirt out, leading to fire, serious injury, or death. Check for oil leaks daily and repair them immediately. Explosion Caused by Lighting Equipment When checking fuel, oil, battery electrolyte, or coolant, always use lighting with anti-explosion specifications. When taking the electrical power for the lighting from the machine itself, follow the instructions in this manual. 1-14 WA430-6 .
