MAINTENANCE
Engine air cleaner
Refer to the engine manufacturer 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 manufacturer 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 manufacturer 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.
Blade- refer figure 4
Check the condition of the blades and central fastener at regular intervals, or after striking a solid
object, or if the mower begins to vibrate abnormally. The blades with use, will loose their sharp
edge and the quality of the grass finish will deteriorate. When this happens the blades should be
replaced in sets.
CAUTION
Blades must be replaced in sets to maintain
balance
