MAINTENANCE
CLEANING THE AIR CLEANER
• Stop the engine and allow the machine
to cool down before performing
maintenance.
· The engine, muffler, radiator and many
other parts of the machine are hot
immediately after the engine is
stopped. Touching it will cause burns.
• Wear required appropriate equipment
such as protective goggle and filter
mask when using compressed air, as
metal fragments or other objects can fly
and cause serious injury.
• 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.
IMPORTANT: Be careful not to scratch the
element. Do not use an element if it is
damaged.
IMPORTANT: When operating the
machine in very dusty places, perform
inspection and maintenance operations
every day.
IMPORTANT: Be sure to install the
element and dust cap securely. If not,
dust could be drawn into the cylinder,
damaging the engine.

5. Clean the inside of the body (4).
6. Clean the primary element (3) with dried
compressed air (294 to 490 kPa or 43 to 71 psi).
First blow the air from the inside of the
element along the pleats. Then blow the
air from the outside and finally from the
inside again.
