Belt Tension Adjustment / Belt Off
This adjustment is only required for 2 or 3 box stackers. The stacker belt moves the
carriage assembly to the different storage boxes. If it is not adjusted correctly your
results may be:
1)
If too tight, this will cause the carriage not to move to the next storage box or
move very slowly.
2)
If to lose the stacker will make a “machine gun” type of sound.
3)
If the belt is off, the carriage box will not move.
The belt is located in the bottom of the stacker. The belt may be viewed through the back
plate by removing the side and bottom screws that hold this in place. At this time a test
can be done to check the tension on the belt. The belt should not be drooping, but also
not so tight that if you pinch the middle with your fore finger and thumb, it is difficult to
get the top and bottom to meet.
This tension can be adjusted by moving the positioning motor of the stacker. The
positioning motor is attached to the stacker by the four screws located under box two on
the stacker bottom plate. Loosen these screws and move the motor where it needs to be,
then tighten. On older stackers you may need to adjust the belt length, or bend the roller
mount that holds the belt opposite of the positioning motor.
