MAINTENANCE
EVERY 250 HOURS
CLEANING THE COOLER FINS
• 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 damage
the fins when cleaning.
• When using compressed air or
pressurized water, make sure the
pressure is no higher than 200 kPa (28
psi) and hold the nozzle sufficiently
away from the fins.
IMPORTANT: When using water, cover the
electrical system to prevent water from
getting in.
IMPORTANT: When operating the
machine in very dusty places, perform
inspection and maintenance operations
every day.
1. Open the left side cover and the engine
hood.
2. Blow compressed air on the fins to
remove mud and dirt stuck on them.
