Adjusting Conveyor Belt Tension; G1066Z - Grizzly G1066R Owner's Manual

Note: Increasing pressure roller tension will
increase workpiece pressure on the conveyor
belt. Increasing this pressure could increase
the likelihood of jams and make the sanding
process less forgiving of irregularities in the
workpiece. Experiment to determine optimal
tension for your workpieces.

ments are controlled by the adjustment bolts
located at each end of the front and rear conveyor
rollers. If the conveyor belt is too loose or tracks
off to one side, it must be adjusted.

infeed end to avoid re-adjusting conveyor
drive chain. Conveyor belt tracking adjust-
ments must be made while the conveyor
belt is running. Use extreme care to ensure
that clothing, hair or jewelry is kept safely
away from moving parts.
