Common causes which require replacement of the conveyor feed belt are
：
normal wear and tear,
inadvertent contact with the sanding drum abrasive during operation, tears caused by mistracking
of the conveyor feed belt, or excessive build-up of non-removable film.
The following steps describe how to remove and replace the conveyor feed belt when necessary
：
1. Disconnect the machine from the power source.
2. Using the Height Adjustment Handle, raise the sanding drum to its highest position
（
roughly 3”
above the conveyor belt table
）
.
3. Using a Phillips type screwdriver, remove the 2 screws and star washers securing the front nip
guard to the variable speed control box. Then remove the front nip guard by sliding it to the left
and off the outboard drive roller bushing.
（
See Figure 21 for reference.

4. Using the supplied 6 mm hex wrench key, remove both conveyor table mounting bolts on the
outboard, open side of the wide drum sander.
（
See Figure 12 in the Drum Alignment section
for reference.

5. Reduce tension on the conveyor feed belt by rotating both the inboard and outboard conveyor
feed belt tracking adjustment screws in a counterclockwise direction.
（
See Figure 14 and 15 in
the Conveyor Feed Belt Tracking Adjustment section for reference.
）
6. Remove the used conveyor feed belt by grasping both sides of the belt as shown in Figure 21.
Gently lift the conveyor table as you slide off the conveyor feed belt. If the belt will not move,
further reduce the tension on the feed belt and ensure you are lifting the table high enough to
allow the feed belt to slide off.
7. To install the replacement conveyor feed belt, follow Step 6 through 3 in reverse order. Center
the new feed belt on the conveyor feed belt table and evenly tension the new feed belt using
the inboard and outboard tracking adjusters. If you experience tracking problems, consult the
Conveyor Feed Belt Tracking Adjustment section.
