and the abrasive strip must be replaced. 
 
1.  Heed all warnings and use extreme caution when performing this cleaning 

operation. 

 
2.  Set the conveyor belt speed control knob to lowest feed setting. Avoid 

contact with conveyor feed belt. 

 
 
3.  Open the protective dust cover to expose the sanding drum and abrasive 

strip. 

 
4.  Use a long belt cleaning stick to distance your hands from the rotating 

drum. 

 
 
5.  Turn on the machine, grip the belt cleaning stick with two hands, rest the 

cleaning stick on the casting which houses the sanding drum. Gently lower 
the cleaning stick onto the rotating drum, moving the cleaning stick from 
side to side to remove the impacted sawdust. (See Figure20.) 

 
6.  When cleaning is completed, remove the stick, turn off the machine, and 

close and latch the protective dust cover. 

 

CONVEYOR FEED BELT REPLACEMENT 

 
Common causes which require replacement of the conveyor feed belt are: 
normal wear and tear, inadvertent contact with the sanding drum abrasive 
during operation, teats caused by mis-tracking of the conveyor feed belt, or 
excessive build-up of non-removable film. 
 
The following steps describe how to remove and replace the conveyor feed 
belt when necessary. 
 
1.  Disconnect the machine from the power source.   
 
2.  Using the Height Adjustment Handle, raise the sanding drum to its highest 

position (roughly 3” above the conveyor belt table).   

 
 
3.  Using a Phillips  type screwdriver, remove the 2 screws and star washers 

securing the front nip guard to the variable speed control box. Then 
remove the front nip guard by sliding it to the left and off the outboard drive 
roller bushing. (See Figure 21 for reference.)
