3.4.11 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
properly and accurately:
1. Turn off the power and disconnect the power cord.
2. With the top cover ON, place machine on a flat level surface on it’s left side and remove
bottom cover.
3. Inspect the encoder bracket and mounting screws (Figure 18, page 22). Make sure the
bracket is not bent, and that the screws are tight.
