Conveyor Belt Replacement

To replace the conveyor belt:

1.Disconnect the machine from the power source.

2.Raise the drum to its highest position using the handwheel (Figure 19, Item A).

3.Remove the belt tension by loosening both take-up nuts (Figure 19, Item B).

4.Unscrew the three screws (Figure 19, Item C) that attach the conveyor to the bracket.

5.Unbolt the two hex head bolts (Figure 19, Item D) that hold the bracket to the bench or stand.

6.Slide the conveyor belt off the conveyor and replace it with a new belt.

7.Reverse the procedure for installation.

Tension Roller Alignment

1.Remove the abrasive strip (Figure 20 Item E) from the drum.

2.Loosen the two bearing hex nuts (Figure 20, Item F) on the outboard side of the drum and two cap screws on the inboard side (Figure 20, Item G).

3.This will allow the tension rollers to drop to their lowest position.

4.Lower the sanding drum so that it just touches the conveyor bed.

5.Turn the drum height handle one complete revolution to raise the drum.

6.Retighten the bearing hex nuts and the cap screws.

Drum Height Control Adjustment

If the height control mechanism does not operate easily or smoothly, or there is excessive vertical movement of the drum carriage, perform the following adjustments.

1.To reduce the handwheel backlash, tighten the locknut on the height adjustment screw (Figure 21, Item J).

2.Thoroughly lubricate all mating surfaces and height adjustment screw (Figure 21, Item K).

Tension Roller Pressure Adjustment

You can also adjust the spring-loaded screws (Figure 20, Item H) found on the pressure roller brackets, to increase or decrease roller pressure. If you are getting snipe marks at the leading end of the board adjust the outfeed roller pressure. If the snipe marks occur on the trailing end of the board, adjust the infeed roller pressure.
