Tension Roller Adjustment

Step 2: Now repeat Step 1 on the right (inboard) side of conveyor. Compare the measurements from side to side. If they are not equal, loosen one of the brackets that hold the roller in place. Tip this bracket until the distance between the roller and the straight-edge are equal from side to side, then tighten the bracket.

Snipe marks result from too much tension roller pressure and are identified as a visible line running across the width of the board approximately 2-1/4” from the end of the board. If a snipe mark occurs on the leading edge of the board, adjust the outfeed tension roller. If a snipe mark occurs on the trailing end of the board, adjust the infeed tension roller.

Tension roller pressure can be decreased in one of two ways:

Method 1: Loosen spring retaining screws (Figure 34). Do not disengage screws entirely.

Method 2: Raise height of tension rollers as follows. Repeat “Initial Drum Alignment” procedure (page 18), using the drum alignment templates under the drum, except place a few sheets of paper under the tension roller(s) needing adjustment. Do NOT place the paper under the drum or alignment templates. Tighten bolts. Repeat this procedure until the snipe is eliminated.

Improperly adjusted tension rollers (i.e. those set too high, rendering them non-functional) could allow kickback or slippage of pieces being sanded.

Adjusting Table Supports

1.If the conveyor table does not rise and lower easily, measure the distance between the top of the base column support and the bottom of the table support on both the inboard and the outboard side of the machine. See Figures 35 and 36.

2.Compare these measurements; they should be within 1/16”. If they are not, disengage the miter gear on the inboard side of the transfer rod (Figure 35) by prying off the protective cap with a screwdriver and loosening the set screw in the gear’s collar.

3.Adjust the conveyor table height using the height adjustment handle to get the same measurement on both sides. Then re- engage the miter gear on the transfer rod, tighten the set screw, and replace the protective cap.
