3.4.8 Backgauge Encoder/Belt Adjustment
The backgauge encoder system reads the position of the backgauge and sends the information to the
display. The encoder uses a belt and pulley system to read the actual position of the backgauge.
The following checks and adjustments may be necessary to ensure the backgauge display reads
accurately:
1. Disconnect the power.
2. Place machine on a flat level surface on it’s left side.
3. Inspect the encoder bracket and mounting screws (Figure 17). Make sure the bracket is not
bent, and that the screws are tight.

4. Inspect the belt and make sure it is tight but not overstretched. If it is not, loosen the (2)
screws at the rear of the machine, pull belt tight, and tighten the screws. Do not stretch the
belt
5. Make sure the pulley is properly lined up with the belt (Figure 17). If not, the position of the
pulley can be adjusted by loosening the pulley set screw, slide the pulley into place, and
tighten the setscrew.
6. Now move the backgauge forward and backward through its full range of motion, checking to
make sure the pulley tracks along belt properly.
