conveyor belt
tension & tracking
the conveyor belt tension and tracking must be
properly adjusted to ensure that the workpiece
correctly and safely passes underneath the sand-
ing drum and that the conveyor belt does not
become damaged during operation.
if the conveyor belt slips on the rollers then the
belt tension needs to be increased.
if the conveyor belt moves to one side or the other
when it is running, then the belt tracking needs to
be adjusted.

terclockwise until you can move the belt
from side-to-side with your hand. then,
center the belt on the rollers.

belt tracking
1. run the conveyor belt at high speed and note
if it tracks to one side or the other—this make
take a couple of minutes to show up.
Note:
To avoid damaging the belt, do not
allow the belt to track off the rollers.
— if the conveyor belt does not track to one
side or the other, no further adjustments
are necessary.
Note:
In the next step, you may have to wait
for several minutes to notice a change in
tracking.
2. rotate the tensioner screw clockwise on the
side the belt is tracking toward until the belt
moves to the center of the rollers, then back
off the screw until it stops tracking to the
opposite side.
3. allow the belt to run for several minutes to
make sure it is tracking properly. if neces-
sary, repeat this procedure until the belt is
properly tracking.
