it into the posture for changing hydraulic oil. Stop the
engine.

3. Clean the filter mounting position of the filter head (3).
Apply hydraulic oil to the O ring (4) of a new filter
cartridge.

wrench.
Tighten it until the O ring is crushed and the top of the

mounting position of the filter cartridge.
6. Store the safety bars, lower the body and check the oil
level in the hydraulic oil tank.

of the level gauge.
