If the performance of the machine is poor or excessive sparking is observed through the
ventilation slots, the carbon brushes must be replaced. Remove the two covers of the brush
housing (23) with a screwdriver. Remove the two worn brushes. Insert the new brushes (29),
replace the covers and screw them into position. The new brushes may cause sparging until
they have taken on the shape of the motor. Repeat the procedure at the other side.
CAUTION: The brushes must always be replaced in pairs.
CAUTION: Always disconnect the machine from the power supply before removing any
electrical covers.
