The drums can be adjusted in fine increments at the pil-

low block bearings and in larger increments by using the

table lift screws.

While adjusting the drum, keep in mind that having the

drum parallel to the conveyor belt (see

Figure.26) 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

height.

belt,.do.these.steps:..

1.. DISCONNECT SANDER FROM POWER!

2. Open the top cover.

3. Loosen the lock nuts (see Figure.27) on the drum

pillow block bearing housing.

4. Place the gauge boards on the conveyor table and

position them under the pressure rollers (see

Figure.

38).

5. Raise the table until the gauge boards just touch the

bottom of the sanding drum.

N

ote: A good way to know when they are touching is

to rock the sanding drum back and forth while rais-

ing the table until you hear or feel contact with the

gauge boards.

6. Lower the table one full turn of the handcrank han-

dle. Wait until the chain starts moving before start-

ing to count the handcrank handle rotation.

7. Starting at one end, place a 0.002" feeler gauge

between the sanding drum and the gauge board.

(The feeler gauge should slide with moderate resis-

tance, 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 drum-to-conveyor tracking on

Page.31.

— 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.
