6. Replace the 2 blades to ensure a smooth even cut and re-fit them on the
mower in the reverse direction they were removed. (Fig Y)
7. Lastly, secure the nuts firmly, (20-25Nm) repeating this for the other blade.
8. Replace the blade mounting plate (24) with new blades attached, then
the outer flange (26), followed by the blade bolt (25). Retighten the blade
bolt tightly (50 – 59Nm).
NOTE: Use a wooden block to stop the blade from turning. The 2 blades
should be tightened fully but check to ensure they can still swing back
if they were to hit a solid object. Where required tighten the bolts with a
torque wrench, the centre disc blade bolt torque: 50 – 59Nm and the four
blades torque: 20-25Nm. If you do not have a torque wrench ask a mower
service dealer to tighten the blade bolts before you use the mower.
Check lawn mower blades regularly. Look for damage, bends and
dullness. Blades should be replaced every year or two depending on
usage, or when they become worn and no longer cut the grass cleanly.
The performance of grass catching can also reduce if the blade becomes
worn. Replacement blade sets are available for purchase from www.
extrabattery.com.au, or by calling 1800 909 909.

Air Cleaner Maintenance

The air cleaner system uses a pleated filter.
IMPORTANT A dirty air filter (21) will restrict air flow to the carburettor.
To prevent carburettor malfunction, service the air filter (21) regularly.
Check that the air filter (21) is clean and dry of dirt.
Filters thick with debris will not allow the engine to breathe and result in
difficult starting and poor engine performance.
The air filter (21) should be checked after approximately 25 hours of use,
or annually.
1. Undo the top clip that holds the filter cover (22). ( Fig Z)
2. Open the air filter cover (22) and remove the air filter (21). ( Fig AA)
3. To loosen debris, gently tap the air filter (21) on a hard surface. If the filter
is excessively dirty, replace with a new filter.
4. Wash the filter in liquid detergent and water. Then allow it to thoroughly
air dry. Do not oil the filter.
5. Re-install the air filter (21).
6. Close the air filter cover (22) and secure the fastener.
NOTE: Refer to engine manual for further information.
CAUTION. Never use fuel or low burning paint solvents to clean the filter.
A fire or explosion could result.
CAUTION. Clean the filter in a solution of household detergent and warm
water. Ensure the filter is dry before re fitting.
