the table is used to lock and unlock the table to permit
adjustment.
There are two positive lock stop positions: at 90
o
(that is, at
a right angle to the platen) and at 45
o
downward
(essentially 90
o
+ 45
o
or 135
o
total to the platen.)
To Tilt the Belt Sander Table:
1. Unlock the locking handle on the side of the table.
2. Using the pointer and scale, set the angle to any
required angle between 20
o
upward and 45
o
downward.
3. Lock the lock handle.
To Tilt the Table to Exactly 45
o
:
1. Flip out the stop bracket (see Figure 20).
2. Unlock the locking handle.

Adjusting the Belt Sander Arm
The arm which holds the sanding belt can be
positioned at a full vertical position, a full horizontal

the arbor cover.
2. Move the arm to vertical until it contacts its stop.
3. Tighten both of the lock bolts, and replace arbor cover.

2. Use a machinist's protractor and level to set the arm to
the required angle.
3. Tighten both of the lock bolts and replace arbor cover.
