Komatsu — PRECAUTIONS WHEN HANDLING AT HIGH TEMPERATURES

SAFETY 1 MOUNTING AND DISMOUNTING Never jump on or off the machine. Never get on or off a moving machine. When mounting or dismounting, always face the machine and use the handrail, track shoes and track frame step. Do not use the machines controls or hoses as hand holds when climbing on or off the machine. Controls and hoses can move and do not provide solid support. Movement of the controls may cause unexpected machine move- ment and injury. Ensure safety by always maintaining at least three point contact of hands and feet with the handrails, steps and track shoes. Always remove any oil or mud from the handrails, steps and track shoes.

If they are damaged, repair them and tighten any loose hardware. Repair any damaged hand hold, and tighten any loose bolts. Hand holds, track frames and shoes must free of oil, grease and/or excessive dirt. 1 FIRE PREVENTION FOR FUEL AND OIL Fuel, oil, and antifreeze can be ignited by a flame. Fuel is particularly flam- mable and hazardous. Keep any flame away from flammable fluids. Stop the engine and do not smoke when refueling. Tighten all fuel and oil caps securely. Refueling and oiling should be done in well ventilated areas. Keep oil and fuel in the determined place and do not allow unauthorized persons to enter.

1 CRUSHING OR CUTTING PREVENTION Do not enter, or put your hand or arm or any other part of your body between movable parts such as between the work equipment and cylinders, or between the machine and work equipment. If the work equipment is operated, the clearance will change and this may lead to serious damage or personal in- jury. 1 PRECAUTIONS WHEN HANDLING AT HIGH TEMPERATURES Immediately after operations are stopped, the engine coolant, engine oil, and hydraulic oil are at high temperatures, and are still under pressure. Attempting to remove the cap, drain the oil or coolant, or replace the filters may lead to serious burns.

Always wait for the tem- perature to go down, and follow the specified procedures when carrying out these opera- tions. To prevent hot water from spurting out: Turn the engine off. Allow the coolant to cool. Slowly loosen the cap to relieve pressure before removing it. To prevent hot oil from spurting out: Turn the engine off. Allow the oil to cool. Slowly loosen the cap to relieve pressure before removing it. 1-10 D87E-2 D87P-2
