Routine Maintenance
Drive Belt
Drive belt tension is factory set and should not require adjustment. Periodically check the drive belt tension. Proper belt tension is achieved when
10 lbs. of force at the mid-span of the belt produces ½ inch of deflection.
To increase belt tension, release tension using quick release lever (See Figure 6).
Turn the adjustment screw “OUT” (See Figure 21) one quarter turn. Restore
tension using quick release lever and check adjustment. Repeat this process
if necessary. To lower tension, the adjustment screw is turned “IN”.
Bearings
Periodically check the bearings for wear or damage according to the
following schedule:
Guide rollers

To decrease the travel or reduce the reach on the grip control,
follow this procedure:
1. Loosen the locknut on the control rod. (See figure 20A)
2. Screw the control rod
adjuster “out”
until desired reach
is found.
3. Tighten the locknut.
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 large accumulations of debris which could interfere with the performance of the tension roller.
NOTE: The tension lever should be in the run/tight abrasive position to blow out.
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 from the dust bag. Turn the dust bag inside out and
machine wash in cold water to prevent pore blockage and loss of dust recovery.
