MAINTENANCE
After First 50 Hours (New Machines Only)
Replacing the Hydraulic Oil
Return Filter
WARNING
¡¡
¡¡
¡Stop the engine and allow the machine
to cool down before performing
maintenance.
• The engine, hydraulic lines and many
other parts of the machine are hot
directly after the engine is stopped.
Touching these parts will cause
burns.
• The hydraulic fluid is also hot and
under high pressure.
Be careful when loosening caps and
plugs. Working on the machine under
these conditions could result in
burns or injuries due to the hot oil
spurting out.
¡¡
¡¡
¡Oil may spurt out if caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.
• When removing plugs or screws or
disconnecting hoses, stand to the
side and loosen slowly to gradually
release the internal pressure before
removing.
1. Open the rear door.
2. Remove the plugs (1).
3. Using a filter wrench, turn the return filter
(3) counterclockwise and remove it.
4. Clean the surface of installation of the filter
stand.
5. Apply a thin layer of oil to the packing of
the new filter.
6. Install the new return filter by hand.
7. Tighten 2/5 more turn with the filter wrench
after the filter packing comes in contact
with the surface of installation.
8. Inspect the level with the sight gauge (2),
and replenish if the level is low.
Refer to page 105 “Inspecting the
Hydraulic Oil Level and Replenishing”.
