REPLACE HYDRAULIC OIL FILTER ELEMENT

The parts and oil are at high temperature after the engine is stopped, and may cause burns. Wait for the temperature to go down
before starting the work.
When removing the oil filler cap, 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 during normal bucket
operations. For details, see "MAINTENANCE INTERVAL FOR HYDRAULIC BREAKER (PAGE 4-15)" when carrying out
