Maintenance
Checking foreign material in drained oil and on filter:
After oil is changed or filters are replaced, check the oil and fil-
ters for metallic particles and foreign material. If large quantities
of metallic particles or foreign material are found, consult your
KOMATSU distributor.
Fuel strainer:
If your machine is equipped with a fuel strainer, do not remove it
while fueling.
Oil change:
Check or change oils in the places where dust is scarce to keep
foreign materials away from oils.
Warning tag:
Attach the warning tag to the starting switch or other appropriate
control lever to avoid someone who is not aware of the circum-
stances from starting the engine.
Obey precautions:
During the operation, always obey the precautions on the safety
label attached to the machine.
Welding instructions:
Turn off the engine starting switch.
Do not apply more than 200 V continuously.
Connect grounding cable within 1 m from the area to be
welded.
Avoid seals or bearings from being between the area to be
welded and the position of grounding
Do not use the area around the work equipment pins or the
hydraulic cylinders as the grounding point.
Fire prevention:
Use nonflammable cleaner or light oil for cleaning parts. Keep
flame or cigarette light away from light oil.
Clamp faces:
When O-rings or gaskets are removed, clean the clamp faces
and replace the 0-rings and gaskets with new ones.
Be sure to fit 0-rings and gaskets when assembling.
