CLEANING THE VACUUM MOTOR FILTERS
Inspect the vacuum motor lters once a week. Open the Bag Housing
Door (2) and remove foam lter from bottom of dust bag chamber. Pull off
lint lters from top of vacuum motors. To clean, shake lters or tap lightly
on a hard surface. Reinstall lters on motors and replace foam lter.
BRUSH BELT
CAUTION!
Belt pulleys can become hot during normal use. To prevent
burns, avoid touching the belt pulley when servicing the
drive belt.
The belt should be checked regularly to be sure it is in good condition.
Remove the two bolts from the rear of the dust bag chamber. Close door
and tilt entire top section of machine forward until it rests on the oor.
Tighten belt by turning the adjustment nut behind the motor base
clockwise until there is enough belt tension to prevent slipping. Tilt upper
section back to its upright position, and replace bolts in dust bag chamber.
Replace belt if showing signs of wear.
NOTE: Overtightening belt can cause premature failure of brush and
motor bearings.

B - ADJUSTING FOR BRUSH WEAR
NOTE: Cut away any hair or thread wound around the brush roll or the
belt pulley because the buildup could cause the belt to rotate unevenly.
When brush shows signs of wear, the brush bearing housings can be
rotated to a second mounting position.
Loosen brush roll belt. Tilt entire machine back on handle, remove the ten
Yearly screws and bottom plate. Remove belt from brush pulley, then pull brush
roll from machine. Rotate Brush Bearing Housings to the "worn brush
position" (A), to move the brush closer to the oor. Reinstall brush with
rotated housings into machine.
X If housings are in worn position when brush is removed and more brush
to oor contact is desired, the brush must be replaced. When installing a
new brush, be sure the bearing housings are positioned for a new brush
(B), or damage to oor or machine will occur.
CIRCUIT BREAKER
The Circuit Breaker (8) keeps the motor from being damaged in case it
becomes overloaded.
Whenever the circuit breaker trips, check to see if the Brush Height
Adjustment is set too low or if there is debris wrapped around the brush.
Re-adjust the brush height or remove the debris from the brush. Then
push the button to reset the circuit breaker.
If the circuit breaker trips repeatedly, call your local Nil sk Distributor for
service.
VACUUM MOTOR BRUSHES
Have your Nil sk Dealer check the carbon brushes in the vacuum motors
once a year or every 500 hours.
The vacuum motors will be ruined if they are run with worn-
out brushes. This kind of motor failure is not covered by
warranty.
