If the breaker is tripped, turn the sander off and reset the circuit breaker by pressing the button (Figure 2, Item C). Be sure to turn the sander off before resetting the circuit breaker to avoid unintentionally starting the sander 9 This Page Intentionally Left Blank 10 Conveyor Belt Tracking Belt tracking adjustment may be necessary during the break-in period and normal operation to compensate for belt stretching. Abrasive belt tension must be properly adjusted before adjusting the tracking. Adjust the belt tracking while the conveyor belt is running at its fastest speed. Tighten the hex nut (Figure 5, Item B) on the side the belt is drifting towards, and loosen the hex nut on the opposite side. Use the attached wrenches (Figure 5, Item C) to adjust the hex nuts. Note: Adjustment should be made in 1/4 turns of the hex nut. Allow time for the belt to react to the adjustment. Do not over adjust. Conveyor Belt Tension Conveyor belt tension adjustment may be necessary during the break in period to compensate for belt stretching. If the conveyor belt can be stopped by hand pressure applied directly to the top of the conveyor bed, the belt is too loose. Insufficient belt tension will cause slippage of the conveyor belt on the drive roller during sanding operations. Excessive belt tension can cause tracking problems and result in bent rollers, bent take-up brackets and premature conveyor belt wear. Adjust the hex nuts (Figure 5, Item B) on both sides of the conveyor to obtain a tight, and equally tensioned, conveyor belt. Use the attached wrenches (Figure 5, Item C) to adjust the hex nuts. Drum Height Control Drum height is controlled by the height adjustment handle (Figure 5, Item A). Turning the handwheel in a counterclockwise direction lowers the drum. Turning the height adjustment handwheel one revolution lowers the drum approximately 1/16”. Figure 5 A B C 11 Checking Drum Alignment The sanding drum comes preset from the factory. If a problem with the drum alignment occurs, follow the instructions listed below. 1. Lift the knob (Figure 6, Item A) to open the dust cover and remove the abrasive strip. If you are unsure how to do this, see the “Wrapping Abrasive Strips” section in this manual. 2. Using a metal straight edge, or ruler, as a thickness gauge (Figure 6, Item B), insert the gauge between the drum and the conveyor bed on the outer end of the drum. 3. Open the dust cover and lower the sanding drum while slowly rotating the drum by hand until the drum lightly contacts the thickness gauge. 4. Remove the thickness gauge and place it under the drum at the opposite end. If the drum does not contact the thickness gauge to the same degree as the other end of the drum, alignment is necessary. Aligning the Drum 1. Loosen the two hex cap bolts (Figure 7, Item C). 2. Lay the thickness gauge under the drum lengthwise. 3. Adjust the knob, (Figure 7, Item D) until the drum contacts the gauge equally along its entire surface. Turn the adjusting knob clockwise to lower the outboard end of the drum, and counterclockwise to raise the outboard end of the drum. 4. When the drum is parallel to the conveyor, tighten the two hex cap bolts. Fine Tuning Drum Alignment When sanding boards wider than the drum, drum alignment is critical and must be adjusted slightly higher on the outboard end. This will prevent any ridges from developing in the stock. Always check it on a piece of scrap wood, as follows, before sanding the work piece. Run a piece of scrap wood approximately 6” wide by 16” to 18“ long through the sander sideways so that the end of the board extends past the end of the drum. Turn the board 180 degrees and sand the same side without changing the sanding height. If a ridge is visible where the drum overlaps, loosen the two hex cap bolts (Figure 7, Item C) and turn the adjusting knob (Figure 7, Item D) slightly. Turn the adjusting knob clockwise to lower the outboard end of the drum and counterclockwise to raise it. Tighten the two hex cap bolts. Repeat this process until the ridge is gone and the entire board is sanded.

You can use the original abrasive belt that came with the sander as a template for cutting your own strips. 1. Mark and cut a taper at one end of the roll, as shown in Figure 8. 2. Square off the end of the taper, as shown in Figure 8. 3. Squeeze the fastener lever (Figure 9, Item A) on the outboard end of drum, and insert the tapered end of the abrasive (Figure 9, Item B) so that it uses most of the width of the slot. Release the fastener lever to securely hold the strip end to the fastener. 4. The square edge of the abrasive strip should follow the edge of the drum, as shown in Figure 9. 5. Wrap the abrasive strip around the drum, being careful not to overlap the Figure 9 windings, as shown in Figure 10. 6. Mark the trailing end o...
