2. Use a permanent marker, paper correction
fluid, or fingernail polish to mark the feed belt
tensioning bolt on both sides. This step will
aid you in keeping track of the rotations as
you turn the bolts, so they remain as even as
possible.
3. Loosen the lock nuts and turn both of the
feed belt tensioning bolts clockwise one full
turn at a time until the feed belt no longer
slips during operation.
—If the feed belt starts tracking to one side,
back off the feed belt tensioning bolt that is
being adjusted
.
—If the feed belt continues tracking to one
side, immediately turn the drum sander
OFF and perform the tracking instructions.
4. Tighten the lock nuts to lock the feed belt
tensioning bolts in place.
Note: When tensioned properly the belt
should not lift off the table, slide back and
forth, or slip.

The feed belt will stretch when new and will even-
tually need to be tensioned. This is most obvious
if the feed belt starts slipping on the rollers.
When you tension the feed belt, focus on adjust

ing the tensioning bolts in even increments.
Adjusting one side more than the other will cause
tracking problems, which will require you to take
additional steps to get the sander operating cor
-
rectly.
