OM2041 9/11 Safety - Section 20 Page 20-3 Precautions With High Temperature Fluids Prevention Of Injury By Work Equipment Immediately after truck operation, engine coolant, engine oil, and hydraulic oil are at high temperatures and are pressurized. If the cap is removed, the fluids are drained, the filters are replaced, etc., there is danger of serious burns. Allow heat and pressure to dissipate before performing such tasks and follow proper procedures as outlined in the service manual. Never enter or put your hand, arm or any other part of your body between movable parts such as the dump body, chassis or cylinders.
If the work equipment is operated, clearances will change and may lead to serious bodily injury or death. Unauthorized Modification Any modification made to this vehicle without authorization from Komatsu America Corp. can possibly create hazards. Before making any modification, consult the authorized regional Komatsu America Corp. distributor. Komatsu will not be responsible for any injury or damage caused by any unauthorized modification. To prevent hot coolant from spraying: 1. Stop the engine. 2. Wait for the coolant temperature to decrease. ROPS Precautions 3. Depress the pressure release button on the cap to vent cooling system pressure.
The ROPS is intended to protect the operator if the truck should roll over. It is designed not only to support the load of the truck, but also to absorb the energy of the impact. 4. Turn the radiator cap slowly to release the pressure before removing. To prevent hot engine oil spray: The Rollover Protection Structure (ROPS) must be properly installed before the truck is operated. 1. Stop the engine. ROPS installed on equipment manufactured and designed by Komatsu America Corp. fulfills all of the regulations and standards for all countries.
If it is modified or repaired without authorization from Komatsu, or if it is damaged when the truck rolls over, the strength of the structure will be compromised and will not be able to fulfill its intended purpose. Optimum strength of the structure can only be achieved if it is repaired or modified as specified by Komatsu. 2. Wait for the oil temperature to cool down. 3. Turn the cap slowly to release the pressure before removing the cap. Asbestos Dust Hazard Prevention Asbestos dust is hazardous to your health when inhaled. If you handle materials containing asbestos fibers, follow the guidelines below: When modifying or repairing the ROPS, always consult your nearest Komatsu distributor.
Never use compressed air for cleaning. Use water for cleaning to control dust. Even with the ROPS installed, the operator must always use the seat belt when operating the truck. Operate the truck or perform tasks with the wind to your back whenever possible. Use an approved respirator when necessary.
