Replacing The Motor Brushes
The carbon brushes should be regularly inspected. They will eventually need to be replaced when the
blocks have worn down to a length of 7mm. Using a flat screwdriver, unscrew the two black plastic covers
found on either side of the motor. Withdraw the worn brushes and springs then replace them with a new
pair.
