Note: This position is for adjustments only. Sanding
belt should not be in contact with workpiece or any
foreign objects when making belt tracking adjust-
ments.
• Observe tracking of sanding belt. If the sanding
belt runs inward, slowly turn the tracking screw
clockwise. If the sanding belt runs outward, slowly
turn the tracking screw counterclockwise. This
should be done until you are sure belt will not run
off sander, or come in contact with internal pads.
Note: After installing a new sanding belt, it raay
become necessary to change the adjustment several
times until the belt becomes pliable.
_k WARNING: If sanding belt begins to wear
excessively on the inner edge, readjust tracking
screw. It is adjusted too far inward and the
sanding belt is rubbing against internal pads.
• When you are sure the belt will not rub against
internal parts, start your sander and fine adjust
the tracking screw until the belt stabilizes. See
Figure 7.
