MAINTENANCE
Engine air cleaner
Refer to the engine owner’s manual for detailed maintenance instructions. The engine air cleaner
elements must be serviced after every 25 hours of normal mowing. The elements must be serviced
more regularly if the mower is used in dusty conditions. Replace immediately if the element is
damaged.
Spark plug
Refer to the engine owner’s manual for detailed maintenance instructions. For best results, remove
the spark plug every 50 hours for gap checking and replace every 100 hours of use. Replace the spark
plug at any time if it is found that the electrodes are pitted or burned or the porcelain cracked. For
replacement refer to engine owner’s manual for correct spark plug.
Muffler
Check the condition of the muffler periodically for rust and cracks. Replace if found to be damaged
as this can lead to increased exhaust noise. Replace only with a genuine original equipment part.
Blades
Check the condition of the blades and central fasteners at regular intervals, or after striking a solid
object, or if the mower begins to vibrate abnormally. The blades with use, will lose their sharp edge
and the quality of the grass finish will deteriorate. When this happens, all the blades should be
removed and replaced with a new set of blades. Always use genuine replacement blades and only
replace blades in sets to maintain balance.
CAUTION
Always ensure the engine is stopped
and the spark plug lead is removed
before attempting any maintenance
on the mower. Secure the mower
safely when titled upwards to access
the underside
Warning
Before carrying out any maintenance on the mower remove the spark plug lead from
the spark plug to prevent accidental starting
