MAINTENANCE
AFTER THE INITIAL 50 HOURS (ONLY FOR NEW MACHINES)
Replacing
Replace the belt in the following cases:
· There are cuts or cracks.
· The belt is worn and touches the bottom of
the V groove in the pulley.
· The belt stretched too loose to be
adjusted.
REPLACING THE HYDRAULIC OIL
RETURN 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.
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.
· 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. Loosen the bolts and remove the flange
(4).
4. Remove the return filter (5).
5. Install a new return filter.
6. Install the flange (4) on its original position.
7. 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.
