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.
