TENSION ROLLER CONTACT ADJUSTMENT 

The tension rollers are factory set for the most versatile use. 

1. 

If necessary, to adjust tension roller contact, loosen 

the four socket head screws holding the tension rol-

ler brackets (two per side; front and back – shown 

in opposite picture). 

2. 

Have abrasive wrapped on drum. 

3. 

With machine unplugged, lower sanding drum until 

it rests on conveyor belt. 

4. 

Raise drum 2 to 3 revolutions. 

5. 

Tighten the four socket head screws (two per side; 

front and back). 

6. 

Raise drum up, off of the conveyor belt. 

7. 

Set drum for proper sanding height and process stock.

CONVEYOR BELT TENSION 

Insufficient belt tension will cause slippage of conveyor 

belt on the drive roller during sanding operation. The 

conveyor belt is too loose if it can be stopped by hand 

pressure applied directly to the top of the conveyor belt. 
Excessive belt tension can result in bent rollers, prema-

ture wearing of the bronze bushings or conveyor belt 
To adjust the tension of the conveyor belt, first adjust 

the take-up screw nut on both sides of the conveyor 

to obtain approximately equal tension on both sides of 

the belt when taut (see opposite picture). 

CONVEYOR BELT TRACKING 

Belt tracking adjustments are made while the conveyor 

belt is running. 
After the proper belt tension is obtained turn the 

conveyor unit on and set it at the fastest speed setting. 

Watch for a tendency of the conveyor belt to drift to 

one side of the conveyor. 
To adjust the belt tracking, tighten the take-up screw 

nut on the side the belt is drifting toward, and loosen 

the take-up screw nut on the opposite side. 
Adjusting the take-up screw nuts on either side of the 

conveyor allows belt-tracking adjustments to be made 

without affecting belt tension.

Note: Adjust the take-up screw nuts only 1/4 turn at a time. Then allow time for the belt to react to the adjustments 

before proceeding further. Avoid over-adjustments.
