18. Precautions for Servicing
3-3
Attach the warning tag
When the oil or the cooling water is being drained, attach the "SERVICING IN PROGRESS" tag to a con-
trol lever so that other persons will not start the engine.
Observe the warning labels
Observe the warning labels affixed to the machine.
Observe the precautions for welding
• Make sure to disconnect the battery cables (positive and negative terminals).
• Do not apply more than 200 V continuously.
• Ground the machine within 39 in. (1000 mm) from the welded part.
• Make sure that there is no seal or bearing between the welded part and the grounded part.
• Do not ground around the pins on the implement or the hydraulic cylinder.
Be careful of fire
Clean parts with noncombustible detergent.
Clean mating surfaces before assembly
When you have removed a part with an O-ring or a gasket seal, clean the mating surfaces before install-
ing the new part.
At this point, do not fail to refit the O-ring or the gasket.
Do not drop anything from your breast pocket
When you open the cover and attempt to look down into the inside of the machine, remove loose items
from your breast pocket to eliminate the risk that they may drop into the machine.
Check the undercarriage
After the machine is used at a rocky place, check the undercarriage for damage. Check for loose bolts
and nuts, cracks, wear, and other damage. Loosen the tension of the crawlers more than usual.
Observe the precautions for cleaning the machine
• Do not spray steam directly at the connectors.
• Do not splash water on the monitors in the cabin.
• Do not spray high-pressure water directly at the radiator and the oil cooler.
