WARNING
q
After the engine is stopped, the parts and oil are at high temperature, so there is danger of burns. Wait
for the temperature to go down before starting the operation.
q
When the cap of the oil filler port is removed, oil may spurt out, so turn it slowly to release the internal
pressure, then remove it carefully.
q
When removing cover (1), the cover may fly off under the force of spring (2), so loosen the 4 bolts
slowly.
1. Remove the cap from oil filler (F) on top of the hydraulic
tank.
2. Remove cover (1) and lift up the top of rod (3) from above
to take out spring (2) and strainer (4).
3. Remove any dirt stuck to strainer (4), then wash it in clean
diesel oil or flushing oil. If strainer (4) is damaged, replace
it with a new part.
4. When installing, insert strainer (4) into protruding part (5) of
the tank, and assemble.
5. Assemble so that the protruding part at the bottom of cover
(1) holds spring (2), then tighten with the bolt.
