MAINTENANCE
SNORKEL AIR CLEANER
The SNORKEL air cleaner element must be cleaned after each 50 hours of normal mowing. The element must be cleaned more frequently when the mower is used in dusty conditions.

CAUTION: Do not allow dirt into the AIR TUBE. Engine damage may result. Check the condition of the air tube regularly. Replace the tube if squashed, cracked or 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.
1.Clean area around spark plug to ensure no dirt enters the cylinder when plug is removed.
2.Using the tube spanner provided and an adjustable wrench, remove plug.
3.If a new plug is required refer to the engine manual for the correct spark plug.
4.Set gap between electrodes at 0.7mm to 0.8mm. See (Fig. 9).
5.Install plug in engine and tighten to 20 Nm. If a torque wrench is not available hand tighten plug. Then with tube spanner tighten plug about 1/12 of 1 turn.
CAUTION: Do not overtighten spark plug. Engine 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 blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades in sets to preserve balance. DAMAGED BLADES AND WORN BOLTS ARE MAJOR HAZARDS.
