Troubleshooting - Qualcast QSPP53 Instruction Manual

Check the washer is still slightly domed to keep the pressure on the bolt and 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.
