METHOD FOR REPLACING HYDRAULIC OIL FILTER ELEMENT

Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn injury.
Wait for the temperature to go down, and then start the work.
The oil may spray out when the oil filler cap is removed. Turn it slowly to release the internal pressure,
then remove it carefully.
NOTICE
If the machine is equipped with a hydraulic breaker, the oil deteriorates faster than when performing
normal operations with the bucket. Consequently, carry out maintenance in accordance with "MAINTE-
NANCE INTERVAL FOR HYDRAULIC BREAKER".
1.
Retract the cylinders of the bucket and the arm completely,
fully extend the cylinder of the 2-piece boom and lower the
boom until the bucket teeth rest on the ground. Lower the
blade to the ground.
2.
Set the lock lever securely in LOCK position (L).
3.
Stop the engine.
4.
Open the central right cover.
5.
Remove the screws (1) and remove the cover (2).
