2.Place the straightedge across the TOP of the platen graphite and the idler roller. Measure the gap, if there is one, between the straight- edge and the main roller.

3.Place the straightedge across the BOTTOM of the platen graphite and the idler roller. Measure the gap, if there is one, between the straightedge and the main roller.

Correct Platen-to-Idler Roller Relationship: The distance between the straightedge and the idler roller is approx- imately 18" at both the top and bottom. No adjustments are necessary to the idler roller position.

Idler Roller Incorrect: The distances between the straightedge and the main roller at both the top and bottom are more or less than 18". Adjust the idler roller.

To adjust the main roller-to-platen relation- ship:

1.Disconnect the sander from the power source!

2.Remove the sanding belt and dust port.

3.Loosen the four motor mount bolts/nuts that secure the motor to the motor bracket. Figure 43 shows two of the four motor mount bolts.

4.Place a straightedge across the TOP part of the platen graphite and the main roller, and adjust the main roller so that it is even with the platen graphite at both the top and bot- tom of the roller. Note—You can also adjust the motor approximately 18" behind the plat- en and skip step 7, but this alternative may be more more complicated.

5.Tighten the motor mount bolts carefully, making sure not to move the motor from its corrected position.

6.Recheck the main roller-to-platen alignment.

If the alignment is correct, then it is adjust- ed correctly. Proceed to step 7.

If the alignment is incorrect, repeat steps 3-5.

7.Adjust the platen as described on the previ- ous page.

8.Replace the sanding belt and dust port, and retrack the sanding belt with the tracking knob before resuming sanding operations.

To adjust the idler roller-to-platen relation- ship:

1.Disconnect the sander from the power source!

2.Remove the sanding belt.
