INSTALLING OR REMOVING
ABRASIVE BELT
Your machine uses a 6"x48" belt. To install or remove the
belt, proceed as follows:
DISCONNECT MACHINE FROM POWER SOURCE.
1. Remove the idler drum guard (A) and side guard (B)
Fig. 20.
2. Turn the belt tension handle counterclockwise to
reduce belt tension to a minimum. NOTE: It may be
necessary when reducing belt tension that downward
pressure be applied on the idler pulley (C) Fig. 21.
3. The sanding belt can then be easily slipped off or
onto the drums, as shown in Fig. 21.
IMPORTANT: Lapless sanding belts can be run in either
direction. Lapped belts should be installed so that the
work will run OFF the lapped portion of the belt and not
into the edge of the lap. Most sanding belts have a
directional arrow on the inside of the belt to show the
direction of rotation.
AFTER INSTALLING A NEW BELT, THE BELT MUST
BE ADJUSTED FOR PROPER TENSION AND
TRACKING.

ADJUSTING THE PLATEN
The platen (A) Fig. 24, is set at the factory 1/32 of an inch
higher than the crown of the drums (B). This allows the
belt, when properly tensioned, to lay flat on the platen
and eliminate stretching and bulging which might occur
if the platen is not at the right height.
When using the machine with a loose belt for
"strapping," the platen is removed and replaced as
follows:
DISCONNECT MACHINE FROM POWER SOURCE.
1. Remove the side cover (B) Fig. 20 and top idler drum
guard (A) Fig. 20.
2. Remove the three screws (C) Fig. 26, that attach the
platen to the machine and remove the platen.
3. When replacing the platen, attach it to the machine
with the three screws (C) Fig. 26. Do not tighten the three
screws.
4. Using a straight edge (D) adjust the platen (A) Fig. 26,
so it is 1/32" higher than the crown of the drums (B),
and tighten the three screws (C).
