WARNING
q
The parts and oil are at high temperature after the engine is stopped, and may cause serious burns.
Wait for the temperature to go down before starting the work.
q
When removing the oil filler cap, oil may spout out. Turn it slowly to release the internal pressure, then remove
it.
NOTICE
If the machine is equipped with a hydraulic breaker, the hydraulic oil will deteriorate much faster than in
normal bucket operations. For details, see "MAINTENANCE INTERVAL FOR HYDRAULIC BREAKER (4-
11)" when carrying out maintenance.
