5.  If the drum does not contact the thickness 

gauge to the same degree as the opposite 
end of the drum, alignment is necessary. 

To align the drum: 

1.  Loosen the four 3/8” hex cap screws – two 

front, two rear (A, Figure 22). This allows the 
entire drum carriage and shroud to be 
pivoted on two screws – one screw in front, 
one in back. 

2.  Lay the thickness gauge under the drum 

lengthwise. See Figure 23. Rotate the fine 
tune adjustment knob (B, Figure 22) until 
the drum contacts the gauge equally along 
its entire surface. Rotate the knob clockwise 
to raise the outboard end of the drum, 
counterclockwise to lower the outboard end 
of the drum. Use the height adjustment 
handwheel to raise or lower the entire drum. 

3.  When drum is parallel to conveyor, tighten 

the four screws (A, Figure 22). 

Fine Tuning Drum Alignment 

NOTE: This is an operational test. Perform this 
alignment after you have become familiar with 
sander operation.  

When sanding boards wider than the drum, 
drum alignment is critical and must be adjusted 
exactly level to slightly higher on the outboard 
end. This will prevent any ridges from 
developing in the stock. Always check this on a 
piece of scrap wood, as follows, before sanding 
the work piece. 

1.  Run a piece of scrap wood approximately 6” 

wide by 30” to 40” long through the sander 
sideways so that the end of the board 
extends past the end of the drum. 

2.  Without changing drum height, rotate the 

board 180° and sand the same side. 

3.  If a ridge is visible where the drum overlaps, 

loosen the four screws (A, Figure 22) and 
raise the outboard end of the drum by 
turning the fine tune adjustment knob (B, 
Figure 22) slightly clockwise.  

Important: Only turn fine tune adjustment knob 
when all four screws (A, Figure 22) are loose. 

4. Repeat this process until the ridge is 

eliminated and the entire board is sanded.  

5.  Tighten the four screws (A, Figure 23).
