Leveling

To adjust the machine leveling follow this procedure:

1. Locate the leveling screw. See Figure 6.

2. Tighten the screw (compress the leveling spring) to sand heavier on drive

belt side of sanding drum.

3. Loosen the leveling screw (relax the leveling spring) to sand heavier on the side

opposite the drive belts.

Condition - Pad creates ridges on both edges or a "hop" is experienced: Rotate

both adjusting screws equal amounts clockwise. Tighten locknuts and test on a

piece of plywood. Repeat procedure until condition is corrected. We recommend

you not exceed 1/8" rotation for each attempt.

Condition - Pad creates a ridge on the tip of the pad: Rotate both adjusting screws

counter clockwise, tighten locknuts and test. Repeat procedure until condition is

corrected. Use only 1/8 rotation for each attempt.

Condition - Pad creates a ridge on only one side of the pad: Either rotate the

adjusting screw of the side effected clockwise or rotate the adjusting screw opposite

counterclockwise, depending on whether the ridge terminates beyond the tip of the

pad or prior to it. If it is prior to the tip, adjust the side effected, otherwise adjust the

opposite side.

Dust Shoe

To adjust the dust shoe follow this procedure:

1. Disconnect machine from power supply.

2. Loosen the four screws fastening the dust shoe to the chassis.

3. Adjust the dust shoe towards the drum to improve recovery of fine particles.

4. Adjust the dust shoe away from the drum to improve recovery of coarse particles.

5. Align the dust shoe with the drum and tighten screws. See Figure 6b.

CAUTION:

Failure to perform maintenance at recommended intervals may void warranty.

Sanding Chamber

Periodically blow out the sanding chamber to prevent large accumulations of debris which could interfere with the performance of the dust

recovery system.

Wheels

Periodically remove the debris from the truck and caster wheels. Debris can cause waves on a sanded surface.

Dust Bag

Remove the dust bag from the machine and shake it thoroughly to remove the sanding dust from the dust bag. Turn the dust bag inside out and

machine wash in cold water to prevent pore blockage and loss of dust recovery.

Drive Belt

Periodically check the drive belts for broken cogs or frayed edges. Frayed edges may indicate poor tracking. Realign effected belt.

Bearings

Periodically check the bearings for wear or damage according to the following schedule.

Arbor shaft: Re-lubricate every 150 hrs. w/.10 oz. of a NLGI grade 2, -30

Motor shaft: After 1

5000 hrs.
