Adjusting Drum Height & Drum-to-
Conveyor Parallelism
The rear drum can be adjusted parallel to the con-
veyor belt in fine increments at the pillow bearings
with the micro-adjust knobs, or the front drum can
be adjusted parallel to the conveyor with the set
screws on the pillow bearings. If, after performing
the following procedure, you cannot adjust the
drums parallel to the conveyor belt, it is possible
that the conveyor table needs further adjustment.
In that case, follow instructions on
Page 48 for
adjusting the table parallel to the drums at the
table lift screws.
Keep in mind that having the drums parallel to the
top of the conveyor belt (see
Figure 58) is criti-
cal to the sanding operation. Take care to adjust
the drums parallel to the conveyor surface within
0.002" from one side to the other.

3. Place the gauge blocks (refer Page 36) on
the conveyor table and position them under
the drums, as shown in
Figure 59.
To adjust the rear drum height and adjust the
drums parallel to the conveyor belt:
1. DISCONNECT POWER TO SANDER!
2. Open the top and pulley covers, remove the
V-belts, and remove sandpaper from the
drums for best results.

4. Raise the table up until the gauge blocks are
approximately 0.010" below the rear drum,
checking with a feeler gauge. This setting will
be used to determine rear drum-conveyor
bed parallelism.
Note: Each full turn of the table height
handwheel raises the conveyor table approxi-
mately 0.020".
5. Loosen the lock lever or lock handle (see
Figures 60 & 61) at one end of the rear
drum.
