Routine Maintenance
The following items need to be periodically inspected
and maintained to keep your sander in good working
condition.
Sanding Chamber
Periodically blow out the sanding chamber to prevent
accumulations of debris which could interfere with the
performance of the tension roller.
Wheels
Periodically remove the debris from the truck and
caster wheels. Debris can cause waves on a sanded
surface.
Dust Bag
Remove the dust bag from the machine and shake it
thoroughly to remove the sanding dust. Turn the dust
bag inside out and machine wash in cold water to
prevent pore blockage and loss of dust recovery.
Drive Belt
Periodically check the drive belt tension. See the
adjustment procedure on page 6.

according to the following schedule:
Guide rollers after 1 st 650 hrs.

Fan shaft after 1 st 2500 hrs.
Tension roller after 1 st 2500 hrs.
