AUTO-TRACK SYSTEM
Your sander features the automatic belt control
system which keeps the belt running in the
center of the pulleys after initial adjustment. The
system has been preset at the factory but may
require adjustment when belts are changed or
an older belt stretches.
ADJUSTING THE AUTO-TRACK SYSTEM
1. Plug in the cord with the tool OFF.
2. Hold handle of sander with one hand and tilt
back until belt is off work and the sander is
resting on the bottom heel of the housing.
3. Turn tool ON by pressing the trigger.
4. For best performance the belt should be in
line with the outer edge of the rear pulley. If the
belt deviates more than 1/8 inch
from the outside of the sander, adjust the belt
position by turning the auto-track adjustment
screw, (Fig. 8) until the belt returns to the
proper position.

SELECTING THE SANDING BELT
It is very important that you select the proper
belt for each particular application. To do this
you should understand the method of marking
or coding on the back of most belts. “CLOSED
COAT” means the surface is densely covered
with as much grit as the adhesive will hold.
“OPEN COAT” means the grit has been
applied evenly, but openly to the surface. An
“open coat” will not clog or fill as readily as
“closed coat”. In general, aluminum oxide
abrasive belts are best for woodworking
because they are tougher and last longer.
Sanding belts should be stored in a cool, dry
place. Do not store near heat or near a window
where the sun can reach them.
