CLEANING INTAKE SCREEN AND COOLING FINS
Inspect and clean the intake screen and the following engine cool-
ing fins: cylinder, cylinder head, oil filter base and oil cooler after
each use or as needed. Blow or brush out any debris to help the
engine run cooler. Continued operation with a clogged cooling sys-
tem can cause severe overheating and possible engine damage.
Never pressure wash this equipment. This
could result in shorting and corrosion in the
wiring harness, oil pressure switch, solenoid
and starter motor.

SERVICING THE AIR CLEANER
The equipment’s air cleaner system is one of the most important
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 filter per the "Maintenance
Schedule" section. Service or replace the filter more often if the
engine is operated under dusty or dirty conditions. Clean the foam
pre-filter (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 configuration (Figure 6) and fol-
low the instructions.
Never run this equipment without the com-
plete air cleaner system installed on the
engine. This could result in premature wear
to the engine.
1. Remove air cleaner cover.
2. Empty dust out of cover.
3. Gently pull filter out of air cleaner housing.
4. Clean inside of housing with damp cloth.
5. Push new air filter into housing.
6. Reinstall the air cleaner cover.

REPLACING THE SPARK PLUG
Replace the plugs every 100 hours of operation or once each year,
whichever comes first. This will help the engine to start easier and
run better.
1. Stop the engine and pull the spark plug wire off of the spark
plug.
2. Clean around the spark plug and remove it from the cylinder
head.
3. Set the spark plug gap (Figure 7) to 1.1 mm (0.043 in.). Install
a correctly gapped spark plug into the cylinder head.
4. Re-install spark plug wire.
