Maintenance
WARNING. When cleaning, or performing any maintenance
such as replacing the blades, it is very important that
the mower is only tipped backwards. Failing to do so will
result in the engine oil flowing into the cylinder and muffler
making starting very difficult if at all. Should this occur, the
mower should be taken to a mower repair shop which is not
covered under warranty
Catcher
CAUTION. Before making any adjustment or maintenance
procedures to the mower ensure it is turned off and the
spark plug lead is removed.
To remove the catcher, raise the guard while lifting the
catcher to dislodge it from the hooks.
WARNING. Check the catcher frequently for cracks and
wear and replace it if damaged.
Replacing the blades
Note. Before making any adjustment or maintenance
procedures to the mower ensure it is turned off and the
spark plug lead is removed.
Note. Wear heavy gloves to protect your hands.
1. Tilt the mower back so the spark plug is facing up.
2. Remove the blade disc with a spanner to remove the
central blade bolt first.
3. Remove both single blades
including the washer and nuts.
4. Clean dirt and grass from
around the blade mounting
area.
5. Replace both blades to
ensure a smooth even cut,
by replacing the washer, then
the half washer, then the nut
securing the blade firmly, (25 – 30Nm).
6. Replace the blade disc and retighten the central blade
bolt tightly (50 – 59Nm).
Note. Use a wooden block to stop the blade from turning.
The 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: 25 – 30Nm.
If you do not have a torque wrench ask a mower service
dealer to tighten the blade bolts before you use the mower.
WARNING. If the blade bolts are not tightened correctly
they could loosen and/or come out and it would be possible
for the blades to fly off while you are operating the mower.
