MAINTENANCE
EVERY 4000 HOURS
REPLACING THE HYDRAULIC OIL AND
CLEANING THE SUCTION STRAINER
• 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 when loosening the caps or
plugs. Working on the machine under
these conditions could result in burns
or injuries due to the hot oil spurting
out.
• 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.
• 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.

to the hydraulic oil level inspection
posture.
