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.
