Conveyor Belt Tracking Instructions
1.
Turn off the air pressure before making any adjustments.
2.
The first step is to make sure the upper conveyor drive roller is perpendicular to the frame. The
motor mounted end of the roller is fixed so this is your starting point. The other end of the roller should
be adjusted in or out until it is in the same relationship to the frame as the motor mounted end.
3.
The next step is to make sure the upper conveyor driven roller is parallel to the upper conveyor
drive roller. This can be determined by measuring diagonally across the conveyor from opposite ends of
each roller. Adjust the mounting brackets for each end of the driven roller until both diagonal
measurements are the same.
4.
Next, locate the lower idler roller assembly mount brackets that are attached to the upper frame.
These mount brackets each have two adjustment screws that allow you to tilt the mount bracket forward
or backward in relation to the conveyor belt travel. Start the adjustment process with all four mount
brackets adjusted perpendicular to the conveyor frame.
5.
If the belt is tracking toward the operator, adjust the driven roller mount brackets as follows:
The mount bracket that is on the same side as the operator should be tilted to the right toward the drive
roller end of the conveyor. The three mounting bolts for each bracket must be loosened before the
bracket can be adjusted. Next, adjust the mount bracket on the opposite side of the same roller the same
angle as the first bracket, but in the opposite direction (toward the driven roller). Both brackets need to
be adjusted the same amount to ensure that the lower idler roller remains parallel to the upper conveyor
surface.
6.
If the belt is tracking away from the operator, adjust the driven roller mount brackets in the
opposite direction as mentioned in step 5.
7.
Make sure all adjustment screws are touching the lower surface of the frame member and that the
bracket mounting bolts are tightened properly.
8.
Turn on the air pressure and test the belt tracking with the manual conveyor buttons on the touch
screen.
