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.
