MAINTENANCE
AFTER THE INITIAL 50 HOURS (ONLY FOR NEW MACHINES)
REPLACING THE PILOT LINE FILTER
• Stop the engine and allow each part of
the machine to cool down before
performing maintenance.
· The engine, 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 immediately after the
engine is stopped.
Be careful not to touch the 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.
· Press the air breather button to relieve
the internal pressure from the tank.
· 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.
• Before performing maintenance on top
of the work bench, clean the footing and
observe the following precautions to
prevent falling.
· Do not spill oil or grease.
· Do not leave tools scattered around.
· Watch your step when walking.
• Never jump down from the machine or
the work bench. When getting on or off
the machine or work bench, use the
steps, handrails or work bench to
support your body. Your weight should
be evenly distributed among the three
contact points (one hand and two feet
or two hands and one foot).
• Do not stand on the dozer blade and
perform maintenance work. Doing so is
dangerous because of the unsteady
foothold. Use the work bench.
1. Open the right side cover.
2. Press the air breather button (2) to relieve
the internal pressure from the tank.
3. Open the engine hood.
4. Loosen the bolts and remove the cover
(A).
5. Turn the case (4) counterclockwise and
remove it.
6. Remove the element (5) and O-ring (6).
7. Clean the inside of the case (4).
8. Apply a thin layer of oil on the O-ring of the
new filter.
9. Install the new element on the filter stand
(7).
10. Apply a thin layer of oil on the new O-ring
(6).
11. Install the new O-ring (6) and the case (4)
on the filter stand (7).
12. Inspect the level with the sight gauge (1)
and replenish if the level is too low.
Refer to “Inspecting the hydraulic oil tank
level and replenishing” on page 5-22.
