Adjusting Conveyor
Belt Tension
The conveyor belt tension has been adjusted at
the factory and should require no further atten-
tion. However, adjust the conveyor belt tension if
you notice that your conveyor belt is slipping or is
tracking off center.
The conveyor belt tension is adjusted by rotating
two adjustment bolts, located on each side of the
conveyor table (see
Figure 90).
Tool Needed:

To adjust conveyor belt tension:
1. DISCONNECT MACHINE FROM POWER!
2. Rotate both
left and right adjustment bolts
(see
Figure 90) equally
to adjust conveyor
belt tension.
When tensioned properly, you
should not be able to lift the conveyor belt off
of table surface or slide it back and forth.

Adjusting Pneumatic
Pulse Jets
The pneumatic pulse-jet cleaning system is
designed to keep the oscillation system electronic
eye and mirror dust free. However, if the pulse
jets are knocked out of position (most likely by
the operator or by a loose sanding belt), they will
stop automatically cleaning the sensor and mirror,
causing the sensor to stop getting the signal to
actuate. This causes the belt to track toward the
sensor and into the limit switch without switching
directions while oscillating.
Tools Needed
Qty
Open-End Wrench 10mm .................................. 1
Open-End Wrench 12mm .................................. 1
Soft Cloth ........................................................... 1
To adjust pneumatic pulse jets:
1.

4. Wipe off sensor and mirror, and adjust aim
of right pulse jet so it points directly at elec-
tonic eye sensor and adjust left pulse jet so it
