1. Run a piece of lumber through the drum sander (Fig. 22) to finish one side of the board.
2. Use a square (A) Fig. 23 to measure the thickness of the lumber.
3. Loosen the screw (B) Fig. 24. Move scale up or down until the cursor shows the exact board thickness that was
measured in STEP 2. Tighten the screw.

1. To check if the feed table is parallel with the drum cylinder, sand a wide board (B) Fig.
19A (preferably 12" or more in width x 2 feet long) until it is flat across the total surface
area on both sides.
A. To do a quick check, draw pencil lines (C) Fig. 19B extending across the width
of the board at several places along the length of the board. DO NOT ADJUST THE
TABLE HEIGHT AT THIS TIME.
B. Reverse the board (end for end) and run the board through the sander. If the
sanding table is set properly, the drawn lines will disappear. If the lines still appear
on the left or right side o
f the board, the table height must be adjusted.
2. Use a ½” wrench to hold the leveling screws (E) and (F) Fig. 20. Insert 3/16" hex
wrench (D), and loosen the hex screws. Rotate leveling screws (E) and (F) Fig. 20, one
flat at a time until parallel. NOTE: One flat on the leveling screw will raise or lower the
table .010". Turn leveling screw (E) Fig. 20 clockwise to lower the table or
counterclockwise to raise the table. Adjust both leveling screws (E) and (F) the same
amount and in the same direction.
3. Tighten screws loosened in step 2.

CHECKING AND ADJUSTING TABLE PARALLEL TO DRUM
NOTE: The table to drum parallelism (D) Fig. 18 has been set at the factory. Distance (D) should be the same
front to back over the entire width of the feed belt. It is best to measure the board thickness at several places along
the length and width to ensure parallelism.
To check and/or to adjust parallelism (D) follow the steps below.

CHANGING DRUM SPEEDS/REPLACING
DRIVE BELT
The drum sander has two drum speeds - 2210 SFM or 3300 SFM, depending on
the belt arrangement on the motor pulley and drum pulley.
To change the sanding drum speeds or to replace the drive belt:
DISCONNECT MACHINE FROM POWER SOURCE.
1. Raise the top drum cover (A) Fig. 25.
2. Remove the two hole plugs (B) Fig. 25.
