MAINTENANCE - All mowers
To Stop the engine
Move the throttle control lever to the “STOP” position. Refer figure 8.
Wait till the engine comes to a complete stop before removing or fitting the grass catcher or mulch
plug to the mower, or attempting any maintenance work on the mower.
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 - refer figure 9.
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 Rover replacement
blades and only replace blades in sets to maintain balance.
Cutting Assembly
• With the engine stopped, remove the spark plug lead and grass catcher or mulch plug.
• Set the height of cut lever to the high cut position, and fold the handle bars.
• Tilt the mower so the spark plug is up.
• Inspect the cutting assembly for damage and wear.
• Check the disc retaining bolts. Tighten the centre bolt to 57-62Nm.
• Return the mower to its normal position and re-attach the spark plug lead.
Before carrying out any maintenance on the mower remove the spark plug lead
from the spark plug to prevent accidental starting.
WARNING
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 tilted upwards to access the underside.
