possibly cause an air leak. Replace a damaged air
cleaner body.

frequently in extreme dusty or dirty conditions).

Washing Method
A. Prepare a solution of the filter cleaner and
water and soak the filter element about 15
minutes. Refer to directions on the filter
cleaner carton for complete information.
B. After soaking the filter for 15 minutes, rinse it
with clear water. Maximum water pressure
must not exceed 276 kPa to prevent damage to
the filter element. Rinse the filter from clean
side to dirty to side.
C. Dry the filter element using warm, flowing air
(71° F max), or allow element to air-dry. Do
not use a light bulb to dry the filter element
because damage could result.
Compressed Air Method
A. Blow compressed air from inside to the outside
of dry filter element. Do not exceed 689 kPa
to prevent damage to the element.
B. Keep the air hose nozzle at least 5 cm from the
filter and move the nozzle up and down while
rotating the filter element. Inspect for holes
and tears by looking through the filter toward a
bright light.
5. Inspect the new filter for shipping damage. Check
sealing end of the filter. Do not install a damaged
filter.
6. Insert a new filter properly into the air cleaner body.
Make sure the filter is sealed properly by applying
pressure to outer rim of the filter when installing.
Do not press on flexible center of the filter.
7. Reinstall the cover and secure the latches.
CLEANING THE RADIATOR AND
SCREEN
(Fig. 23)
To prevent the system from overheating, radiator screen
and radiator must be kept clean. Check and clean the
screen and radiator daily and, if necessary, hourly clean
any debris off these parts. Clean these components more
frequently in dusty dirty conditions.
1. Remove the radiator screen.
