MAINTENANCE
AFTER THE INITIAL 50 HOURS (ONLY FOR NEW MACHINES)
REPLACING THE PILOT LINE FILTER
• Stop the engine and allow the machine
to cool down before performing
maintenance.
· The engine and the hydraulic system
and many other parts of the machine
are hot immediately after the engine is
stopped. Touching these parts will
cause burns.
· The hydraulic oil is also hot and under
high pressure.
Be careful not to touch the hydraulic
oil when loosening the cap or plug.
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 are disconnected
before releasing the pressure in the
hydraulic system.
· When removing plugs or screws, or
when disconnecting hoses, stand to
the side and loosen them slowly to
gradually release the internal pressure
before removing.
2. Turn the case (1) counterclockwise and
remove it.
3. Remove the element (2) and O-ring (3).
4. Clean the inside of the case (1).
5. Coat the O-ring receiving groove on the
new filter with a thin layer of oil.
6. Install the new element on the filter stand.
7. Coat the new O-ring (3) with a thin layer of
oil.
8. Set the new O-ring (3), and then tighten
the case (1) to the filter stand.
Tightening torque: 78.5 ± 4.9 N·m
(57.9 ± 3.6 ft-lb.)
9. Inspect the level with the sight gauge and
replenish if the level is low.
Refer to “Inspecting the hydraulic oil tank
level and replenishing” on page 5-21.
