One brush is replaced from the left-hand side and the

other from the right-hand side. The procedure is the
same.

ATTENTION
Risk of functional disturbances. Do not let the V-belts get
in contact with the grease.
Grease the grease nipples in accordance with the

maintenance intervals using a grease gun.
Use high quality multi-purpose grease and use grease

gun to lubricate.
Clean the roller brush retainers before inserting the

new brushes.
The brushes are inserted in the reverse sequence.
