MOWER CLEANING
REFER ENGINE INSTRUCTIONS
WARNING: To reduce fire hazard, keep the mower
clean.
For best mower performance keep the engine
underside of mower base and grass catcher screen
clean.
WARNING: Maintain engine oil cooling system.
Poor air flow may result in
overspeeding, overheating and engine
damage.
1. Use a brush or cloth to clean the engine of
accumulated dirt, grass and leaves.
2. To clean the rear catcher mower base use a hose to
direct water through the wash port while the engine is
running at a moderate speed. (Fig. 7).
3. To clean the catcher, remove from the mower, empty
and hose out to release grass and dirt from the
screen.
CAUTION: Do not hose the engine. A forced spray of
water may contaminate the fuel system.
Poor engine performance may result.
ENGINE AIR CLEANER
REFER ENGINE INSTRUCTIONS

each 25 hours of normal mowing. The element must be
serviced more frequently when the mower is used in
dusty conditions.
SNORKEL AIR CLEANER

holed.
SPARK PLUG
For best engine performance check the condition of the
spark plug each 100 hours of mowing. A worn or
damaged spark plug must be replaced.
CAUTION: Do not sand blast or file spark plug
electrodes. Grit may release from the plug
and fall into the cylinder. Engine damage
may result.

Using the tube spanner provided and an
adjustable wrench, remove plug.

damage may result.
WARNING: Always disconnect the spark plug wire
before working on the mower to prevent
accidental starting. Before using, always
visually inspect the mower to check that
