When adjusting the drums, they must be aligned
in two ways—perpendicular to the feed direction
(Figure 33) and parallel to the conveyor belt
(Figure 34). In addition, the rear drum should be
set approximately 0.020" (0.5 mm) below the front
drum. (This amount is equal to one full crank of
the handwheel.)

The drums can be adjusted in fine increments at
the pillow bearings and in larger increments by
using the table lift screws (Page 27).
While adjusting the drums, keep in mind that
having the drums parallel to the conveyor belt is
critical to the sanding operation. Care should be
taken to make the tolerances as close as possible
(within 0.002" from one side to the other) when
adjusting the drum heights.
The tolerances for having the drum perpendicular
to the feed direction are much more forgiving,
even allowing up to
1
8" difference from one side
to the other before causing problems.
To align the drums:
1. Disconnect power to the sander!
2. Open the top and V-belt covers and remove
the V-belts
(see Page 31).
3. Remove the sandpaper from the drums.
4. Loosen the lock nuts (see Figure 35) on the
front drum pillow bearing.
