surfaces of the engine every 100 hours of operation or more
often under extremely dusty and dirty conditions.

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

Check the air cleaner body for damage which could
possibly cause an air leak. Replace a damaged air cleaner
body.

Ensure that 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.
