Tip the machine slightly towards the oil filler pipe and reach under the deck.
Hold the blade and unscrew the blade bolt counterclockwise using a spanner wrench.
Remove the washer and the blade.
Inspect the blade adaptor for any signs of damage.
Fit a new blade, locate the blade on the two studs on the blade
fl
ange and then replace the
washer and bolts.
Check the washer is still slightly domed to keep the pressure on the bolt to stop it
unwinding, keeping the blade firmly secure. Then replace the washer (right way around!)
and bolts.
Make sure the blade is correctly located, and then firmly tighten the bolt. Do not over
tighten. The up turn of the blade must project into the motor compartment.
NOTE:
If you are unsure about performing this operation, call our helpline or go to an
authorised dealer to change the blade for you.
