items to maintain. The engine will not run properly and may
be damaged if it is run with a dirty air cleaner system.
Service or replace the paper air fi lter per the “Maintenance
Schedule” section. Service or replace the fi lter more often if
the engine is operated under dusty or dirty conditions. Clean
the foam pre-fi lter (if equipped) every 25 hours of operation,
or sooner under dusty or dirty conditions.
Use the following instructions to clean or replace the air
cleaner components. Locate the engine confi guration
(fi gure 8 or 9) and follow the instructions.
Never run this equipment without the complete air
cleaner system installed on the engine. This could
result in premature wear to the engine.
