ADJUSTING FEED TABLE PARALLEL TO DRUM
Refer to Figure 13.
The drum sander is shipped from the factory with the drum
carriage set parallel to the feed table. However, if adjustment
is necessary:
• To check if the feed table is parallel with the drum cylinder,
sand a wide board (preferably 12" or more in width x 2'
long) until it is fiat acrossthe total surfacearea on both sides.
• To do a quick check, draw pencil lines extending across the
width of the board at several places aloog the length of the
board.
• 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 of the board, the table height must be adjusted.
• Disconnect tool from power source.
• Loosen the four socket head bolts.
• Turn both screw guides equally to raise (counterclockwise)
or lower (clockwise) the table (one revolutionof screw
guide will move the table 0.125").
NOTE: When sandLngpieces wider than 18" and the drum is
not parallel to the table, a step or line will result. It is best to
set the outboard side a few thousandths of an inch higherto
allow sanding a crown rather than a groove.
• Sand the board again to check adjustment;readjust if
necessary.
• Tighten socket head bolts
