Cleaning the Engine Cooling
Areas
Clean the rotating screen, cooling fins, and external
surfaces of the engine every 100 hours of operation or more
often under extremely dusty and dirty conditions.
Important Operating the engine with a blocked
rotating screen, dirty or plugged cooling fins, or cooling
shrouds removed will cause engine damage due to
overheating.
Important Never clean the engine with pressurized
water because water could contaminate the fuel system.
Servicing the Air Cleaner
Service Interval/Specification
Check the air cleaner body for damage which could
possibly cause an air leak. Replace a damaged air cleaner
body.
Ensure the cover is sealing around the air cleaner body.
Air Cleaner Filter: Inspect after every 100 operating hours;
replace after every 200 hours or sooner if dirty or damaged.
Note: Service the air cleaner more frequently (every few
hours) if operating conditions are extremely dusty or sandy.

Cleaning the Filter Element
Important Do not wash or reuse a damaged filter.
1. Washing method:
A. Prepare a solution of filter cleaner and water and
soak the filter element for about 15 minutes. Refer
to the directions on the filter cleaner carton for
complete information.
B. After soaking the filter for 15 minutes, rinse it with
clear water. Rinse the filter from the clean side to
the dirty side.
Important To prevent damage to the filter element,
the maximum water pressure must not exceed 40 psi.
(276 kPa)
C. Dry the filter element using warm, flowing air at
160° F maximum, or allow the element to air-dry.
Important Do not use a light bulb to dry the filter
element because damage could result.
2. Compressed air method:
A. Blow compressed air from the inside to the outside
of the dry filter element. Keep the air hose nozzle at
least 2 inches from the filter and move the nozzle up
and down while rotating the filter element.
Important To prevent damage to the filter element,
do not exceed 100 psi air pressure.
B. Inspect the filter element for holes and tears by
looking through the filter toward a bright light.
