Conveyor Belt
Tensioning
The conveyor belt may stretch with extended use,
causing it to slip on the conveyor rollers. If this
happens, the conveyor belt will need to be reten
-
sioned.
When you tension the conveyor belt, make sure
you turn the left and right adjustment bolts in
even increments. Tensioning one side more than
the other will cause tracking problems, which will
require you to take additional steps to get the
sander operating correctly.
To tension the conveyor belt:
1. Take the reference measurement shown in
Figure 32 on both sides of the conveyor.
Figure 33. Correct conveyor belt hanging gap.
3. Turn both of the adjustment bolts clockwise
one full turn at a time until the conveyor belt
no longer slips during operation.
Note: Make sure the distance of the refer-
ence measurement taken in Step 1 is the
same on both sides.
— If the conveyor belt starts tracking to one
side, immediately turn the conveyor OFF
and perform the tracking procedure below.
Note: Do not overtighten the conveyor belt.
Your goal is reach an approximate
1
⁄2" hang-
ing gap on the underside of the conveyor belt
(see Figure 33) and that the belt no longer
slips on the rollers.
