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.

direct water through the wash port while the engine is
running at a moderate speed. (Fig. 7).

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

enters the cylinder when plug is removed.
2. Using the tube spanner provided and an
adjustable wrench, remove plug.
