ADJUSTMENTS

FIG.12

TO ADJUST PARALLELISM OF

SANDING DRUMS

The front sanding drum has been factory adjusted and

needs no further adjustment. The rear sanding drum

must be adjusted for parallelism.

1. Lift the upper guard up and tilt it toward the rear of

the machine to expose the sanding drums.

2. Using the 6mm wrench provided, rotate the cap

screws, indicated in Fig. 11, on either end of the

rear drum.

3. Turning the cap screws clockwise will raise the

drum while turning it counterclockwise will lower

the drum.

4. Repeat this dial setting on the opposite end of the

drum.

5. Replace the upper guard to its original position over

the drums.

NOTE: For proper operation of the machine, the dial

settings at both ends of the drum must be identical.

FIG. 11

TO ADJUST ROLLER PRESSURE

The pressure rollers maintain tension upon the

workpiece as it passes through the machine. If the

stock refuses to pass through the machine, or the

finished surface is uneven, the tension on the pressure

rollers may need adjusting.

1. Lift the upper guard up and tilt it toward the rear of

the machine to expose the sanding drums.

2. Locate the roller pressure adjustment screws as

indicated in Fig. 12.

3. Using a Phillips head screw driver, turn the screws

clockwise to increase the roller pressure on the

workpiece; or counterclockwise to decrease the

pressure.

4. Adjust both sides of the pressure rollers to ensure

parallelism with the drums.

5. Replace the upper guard to its original position over

the drums.

Do not overtighten the adjustment screw. Too much roller pressure will prevent the workpiece from

passing through the machine, and may cause the feed belt to stop.
