5. raise the table until the gauge blocks just
touch the bottom of the sanding drum.
Note: A good way to know when they are
touching is to rock the sanding drum back
and forth while raising the table until you hear
or feel contact with the gauge blocks.
6. lower the table one full turn of the crank han-
dle. Wait until the chain starts moving before
starting to count the crank handle rotation.
7. starting at one end, place a 0.002" feeler
gauge between the sanding drum and the
gauge block. (the feeler gauge should slide
with moderate resistance, without forcing the
drum to roll.)
8. repeat Step 7 at the other end of the drum.
—if the difference between the two sides is
0.002" or less, skip to the subsection that
covers how to adjust the sanding drum
perpendicular to the feed direction
on this
page.
— if the difference between the two sides is
more than 0.002", then one side must be
adjusted to within 0.002" of the other (with
the ultimate goal of making them dead
even). Continue to the next step.
to adjust the sanding drum perpendicular to
the feed direction:
1. disConneCt poWer to the sander!
2. First measure the distance between the out-
side of the drum and the inside of the dust
scoop (
figure 33). the distances should be
within 1 ⁄
8
" of each other at each end of the
drum.

and dust scoop.
3. if the measurements are not within 1 ⁄
8
", the
drum can be moved by loosening the lock
nuts on the pillow block bearings and moving
one end of the drum forward or backward as
necessary in the slotted holes.
Note: After you have adjusted the drum, do
not forget to tighten the lock nuts and recheck
the alignment by repeating
Steps 1–3.

4. place the gauge blocks on the conveyor table
and position them under the pressure rollers,
as shown in
figure 32.
figure 32. gauge blocks positioned under
pressure rollers and sanding drum.
to adjust the pillow block bearings:
1. loosen the lock nuts (see figure 31) on
one of the pillow block bearings that requires
adjustment.
2. rotate the setscrews 1 ⁄
8
of a turn clockwise to
raise the pillow block bearings (see figure
31).
Note: Turn all setscrew sets an equal
amount.
3. tighten the lock nuts and recheck the align-
ment using the gauge blocks, repeating Steps
1–8 from the previous subsection. tightening
the lock nuts will pull the drum downward
slightly. be sure to adjust to compensate
for this movement.
Do not over tighten the
lock nuts. the pillow block bearings can
break if over tightened.
