TRACKING THE SANDING BELT

The belt tracking adjustment is set at the factory so

that the belt (A) Fig. 23, will run true on the pulleys. If,

however, the belt (A) should lead to one side or the other

on the pulleys, an adjustment can be made by turning

the tracking knob (B). Turning the knob (B) clockwise will

move the belt to the right when facing the sander. Turning

the knob (B) counterclockwise will move the belt to the

left. TURN THE KNOB IN SMALL INCREMENTS TO

ADJUST THE TRACKING.

PLATEN

The platen (A) Fig. 24, is constructed of heavy steel to

properly support the work when sanding. The platen

should be adjusted so it is almost touching the back

of the sanding belt. To adjust the platen, loosen screw

(B), adjust the platen to the desired position and tighten

screw (B).

To remove the platen for operations such as strapping,

contour sanding, polishing, or other special operations,

remove screw (B) Fig. 24, and remove platen (A).

BELT TABLE ADJUSTMENTS

The belt sander table (A) Fig. 25, can be tilted or moved

in or out by loosening lock handle (B), moving the table

to the desired position, and tightening lock handle

(B). NOTE: The lock handle (B) is spring-loaded and

can be repositioned by pulling out on the handle and

repositioning it on the serrated locking stud located

directly under the handle.

To avoid trapping the work or fingers

between the table and sanding belt, the table edge (C)

fig. 25, should be positioned a maximum of 1/16 inch

from sanding belt (D) as shown.

For most sanding operations the table is set at a 90

degree angle to the sanding belt. A positive stop is

provided to insure fast positioning of the table at 90

degrees to the belt. Loosen the table lock lever (B) Fig.

26, and tilt the table to the rear as far as possible. Using

a combination square (E), place one end of the square

on the table with the other end against the sanding belt,

as shown, and check to see if the table is 90 degrees to

the belt. If the table is not at 90 degrees to the belt, turn

adjusting screw with wrench (F). The adjusting screw

should bottom against the frame when the table is 90

degrees to the belt.
