The Belt to Drive the Brush

brush. Check the belt frequently. Replace the belt if
the belt slips on the brush. Remove hair and threads
from the brush roll and the motor shaft pulley before
replacing the belt.

To replace the drive belt, follow this procedure:
1. Make sure the electrical plug is removed from the
outlet.
2. Put the machine upside down.
3. To remove the bottom plate, turn the two cam
latches on the sides of the plate.
4. Remove the worn belt from the pulley on the motor
shaft. See figure 4.
5. To remove the brush, pull the brush out of the slots
in the frame.
6. Clean the vacuum opening in the base of the
machine.
7. Check the bristles of the brush for wear. If the
bristles are worn, see the section "What to Do
about the Wear of the Brush."
8. Put a new belt around the pulley on the brush.
Align the brush roll pulley with the belt guide. See
