C. Clean the engine compartment

Check and clean engine cooling areas, air intake
areas, and the external surfaces of engine. Dust,
hay, and other combustible materials on and around
the engine will cause a fire hazard.

Clean the engine compartment with compressed air
and water. Always avoid spraying on the air intake or
air filter. Wipe engine and hydraulic pumps carefully
with cloth.

Never spray in the engine compartment with a
pressure washer. Do not pour water on the engine.

If necessary, use a brush or sponge to clean larger
surfaces at the rear frame. Rinse radiators gently
with a water hose. Do not scrub or brush radiators to
avoid damage.

Service hatch at the bottom of the loader

There is a service hatch under the loader to help with
the cleaning of the rear frame. Remove the service
hatch, fastened with two bolts, before cleaning the
engine bay to remove dirt from the rear frame.
Reinstall the cover plate after cleaning to protect the
internal components of the loader.

D. Clean cooling systems

Proper cooling is essential. To
prevent overheating, clean screens,
cooling fins, and other external
surfaces of engine. Avoid spraying
water at wiring harness or any
electrical components.

The loader is equipped with a
hydraulic oil cooler, which is located
at the right side of the loader, near the
controls of the loader. Make sure to
clean the oil cooler cell with
compressed air every time you are
servicing the loader - and even more
frequently if the loader is being used
in dusty conditions.

There are two cooling fans on the loader:



Hydraulic oil cooler located on the right side of
front frame.



Engine cooler in the engine compartment.

If the optional air conditioning system is installed,
there is a cooling fan at the rear of the cab, or at the
roof

Keep all coolers clean to ensure reliable operation
and long service life of the loader. If you operate the
loader in dusty conditions, clean the cooling fans and
surfaces daily:

If the loader is equipped with air
conditioning:

A condenser of the

air condition unit is installed behind
the rear window of the Cab, or at
the roof. The condenser can get
damaged easily. Clean the
condenser carefully. The
condenser can get damaged easily
if handled carelessly. Never use a
high pressure washer. You may
use compressed air gun carefully.

4. Add grease to the lubricating

points

Greasing of the pivot points is
essential to avoid wear of joints.
Lack of greasing can cause
significant damage to the
articulation joint and boom pivots in
short period of time.

The following table and pictures
show the location of grease
nipples. Check the lubrication
points before each work shift.

Make sure all joints are lubricated and clean.
Suitable lubrication interval depends heavily on
operating conditions. The need for lubrication must
be checked at least after every 10 hours of use. Add
grease if the joints have become dirty. Adequate
lubrication of the joints must be ensured. Lack of
lubrication will cause the joints to wear quickly.

Use general purpose machine grease. A grease gun
is needed to apply grease to grease nipples. All
lubrication nipples are standard R1/8" nipples.
Replace any damaged nipples.

Clean the end of the nipple before greasing and add
only a small amount of grease at a time. New
lubricant will push out dirt from joints. Wipe excess
grease with a cloth.
