Aligning the drum parallel to the conveyor belt
(see Figure 45) is critical for sanding accuracy.
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 height.

To align sanding drum:
1. DISCONNECT MACHINE FROM POWER!
2.
Remove sandpaper from drum and place
gauge blocks as shown in Figure 46.
Figure 46. Example of gauge blocks placed
under drum.
3. Raise table until gauge blocks just touch the
drum.
Note: A good way to know when they are
touching is to rock the drum back and forth
while raising the table until you hear or feel
contact with the gauge blocks.
4.
Lower table one full crank of the handwheel
(taking handwheel free-play into consider-
ation; or in other words, wait until the chain
starts moving before starting to count the
handwheel rotation).
5.
Starting at one end, find the largest size feeler
gauge that can pass between the drum and
your gauge block. (The feeler gauge should
slide with moderate resistance, without forc-
ing the drum to roll.)
6.
Repeat Step 5 at other end of the drum.
—If the difference between the two sizes
is 0.002" or less, then no adjustment is
necessary.
— If the difference between the two sizes
is more than 0.002", then one end must
be adjusted to within 0.002" of the other.
Continue to the next step.
7.
Loosen table cap screws and adjust height of
table by rotating adjustment knob shown in
Figure 47.

8. Tighten table cap screws and repeat Steps
5-6.
