Conveyor Belt Replacement 

 
To replace the conveyor belt: 
 
1.  Disconnect the machine from the power 

source. Unplug the motor cord from the 
control box. 

 
2.  Raise the drum to its highest position using 

the handwheel (Fig. 16, Item A). 

 
3.  Remove the belt tension by loosening the 

take-up nuts (Fig. 16, Item B). 

 
4.  Unscrew the four socket head cap screws 

(Fig. 16, Item C) that attach the conveyor to 
the bed and remove the conveyor. 

 
5.  Slide the conveyor belt off the conveyor and 

replace it with a new belt. 

Tension Roller Alignment 

 
1.  Remove the abrasive strip (Fig. 17, Item D) 

from the drum. 

 
2.  Loosen all four bearing hex nuts (Fig. 17, 

Item E). 

 
3.  This will allow the tension rollers to drop to 

the lowest position. 

 
4.  Lower the sanding drum so that it just 

touches the conveyor bed. 

 
5.  Turn the drum height handle one complete 

revolution to raise the drum. 

 
6.  Retighten the bearing hex nuts. 
 

Tension Roller Pressure Adjustment 

 
You can also adjust the spring-loaded screws 
found on the pressure roller brackets, to 
increase or decrease roller pressure. If you are 
getting snipe marks at the leading end of the 
board adjust the outfeed roller pressure. If the 
snipe marks occur on the trailing end of the 
board, adjust the infeed roller pressure. 
 

Drum Height Control Adjustment 

 
If the height control mechanism does not 
operate easily or smoothly, or there is excessive 
vertical movement or deflection of the drum 
carriage, perform the following adjustments. 
 
1.  Tighten all four lock nuts (Fig. 18, Item F) 

and then loosen them 1/8 to 1/4 turn. 

2.  Thoroughly lubricate the mating surfaces 

and the height adjustment screw.
