operate the engine with the oil level below the "L" mark
or over the "F" mark on the dipstick.

CHANGE ENGINE OIL AND FILTER

• Only use high quality detergent oil rated with API
service classification SF or SG. Select the oil’s
SAE viscosity grade according to your expected
environmental temperature.
• See Engine Manual for detailed instructions.
CHECK AIR FILTER
This engine is equipped with a replaceable, high
density paper air cleaner element and an oiled, foam
precleaner.
Check the air cleaner daily or before starting engine.
Check for buildup of dirt and debris around the air
cleaner system. Keep this area clean. Also check for
loose or damaged components. Replace all bent or
damaged air cleaner components.
Your engine will not run properly with a dirty air filter.
See Engine Manual for detailed instructions on
changing the air filter.
IMPORTANT: Operating the engine with loose or
damaged air cleaner components could allow unfiltered
air into the engine causing premature wear and engine
failure.
INSPECT MUFFLER/SPARK ARRESTOR
Inspect muffler and (if equipped) spark arrester.
Replace muffler if corroded, as it could create a fire
hazard and/or damage.

REPLACE SPARK PLUGS

Spark plug type and gap setting are shown in
Specifications. See Engine Manual for detailed
instructions.
REPLACE IN-LINE FUEL FILTER
The fuel filter should be replaced once each season. If
fuel filter becomes clogged, obstructing fuel flow to
carburetor, replacement is required. See Engine
Manual for detailed instructions.

CLEAN AIR SCREEN

Air screen must be kept free of dirt and chaff to prevent
engine damage from overheating. Clean with a brush
or cloth to remove dirt and chaff. Do not clean with a
forceful spray of water because water could
contaminate fuel system. See Engine Manual for
detailed instructions.
CLEAN ENGINE COOLING FINS
To ensure proper cooling, make sure the grass screen,
cooling fins and other external surfaces of the engine
are kept clean at all times. See Engine Manual for
detailed instructions.
IMPORTANT: Operating the engine with a blocked
grass screen, dirty or plugged cooling fins, and/or
engine shroud removed will cause engine damage due
to overheating.
