Adjustments

Before putting power to the sander, inspect the machine thoroughly. Check to ensure that all screws are tight, all mechanical functions work freely, belt runs freely and tracks properly, and the disc runs freely, does not come into contact with the guard or table, and the abrasive remains firmly adhered to the sander’s metal disc.

Turn the motor on and check for proper rotation direction of the belts. The sanding belt should move from the idler pulley toward the drive pulley, while the disc should rotate counter- clockwise with the operator facing the disc. Arrow labels are affixed to the sander to indicate these directions.

Platen Adjustment

The platen should not require attention on your new sander. After prolonged use, however, the platen may occasionally need re-adjustment. To do this, proceed as follows.

Refer to Figure 15:

1.Swing the end guard out of position and remove the side cover. Remove the abrasive belt.

2.Using a 6mm hex wrench, loosen the two socket head cap screws inside the belt arm and shift the platen as needed. The platen should be 1/32” to 1/16” above the tangent points of the pulleys and in contact with the belt at both ends. A straight edge can be used with the abrasive belt to align the platen, as shown in Figure 15.

3.Re-tighten the socket head cap screws.

Sanding Table Adjustment

Refer to Figures 16 and 17:

The sanding table may be adjusted from any angle from 15 degrees up, to 45 degrees down. To adjust, loosen the locking wheels (A) on both sides and pivot the table to the desired angle as shown on the trunnion scale (B). Re-tighten the locking wheels (A).

A 45-degree stop (C) is located under the table. Use an angle measuring device to confirm that the angle of the table against the stop is 45 degrees. If it is not, adjust by loosening the hex nut and screwing the stop in or out as needed. Re-tighten hex nut.
