Adjustments
Drum Height Control
Drum height is controlled by the height adjustment
handle (A, Fig. 5). Turning the handwheel in a
counterclockwise direction lowers the drum.
Turning the height adjustment handwheel one
revolution lowers the drum approximately 1/16”.
Conveyor Belt Tension
The conveyor belt is over-
tensioned at the factory for shipping purposes.
Re-adjust before operation to prevent damage
to the machine.
If the conveyor belt can be stopped by hand
pressure applied directly to the top of the conveyor
bed, the belt is too loose. Insufficient belt tension
will cause slippage of the conveyor belt on the drive
roller during sanding operations.
Excessive belt tension can cause tracking
problems and result in bent rollers, bent take-up
brackets and premature conveyor belt and bushing
wear.
Adjust the hex nuts (B, Fig.5) on both sides of the
conveyor to obtain a snug, and equally tensioned,
conveyor belt. Use the attached
wrenches
(C, Fig. 5) to adjust the hex nuts.
Conveyor Belt Tracking
Belt tracking adjustment may be necessary during
the break-in period and normal operation to
compensate for belt stretching.
Abrasive belt tension must be properly adjusted
before adjusting the tracking. Adjust the belt
tracking while the conveyor belt is running at its
fastest speed.
Tighten the hex nut (B, Fig. 5) on the side the belt
is drifting towards, and loosen the hex nut on the
opposite side. Use the attached
wrenches
(C, Fig, 5) to adjust the hex nuts.
Note: Adjustment should be made in 1/4 turns of
the hex nut. Allow time for the belt to react to the
adjustment. Do not over adjust.
