Conveyor belt tracking adjustments may occasionally
be necessary during break-in and normal operation
to compensate for belt stretching. If adjustments
are necessary, follow the instructions below: Belt
tracking adjustments are made while the conveyor
belt is running. With the conveyor unit on and set
at the fastest speed setting, watch for a tendency of
the conveyor belt to drift to one side of the conveyor.
To adjust the belt tracking, tighten the take-up screw
nut (Fig. 9) on the side the belt is drifting toward,
and loosen the take-up screw nut on the opposite
side. Adjusting the take-up screw nuts on both sides
of the conveyor allows belt tracking adjustments to
be made without a ecting belt tension. Adjust the
takeup screw nuts only 1/4 turn at a time. en allow
time for the belt to react to the adjustments before
proceeding further. Try to avoid over-adjustments.
NOTE: Make sure wrench is below surface when
brushing or sanding.
