—If the belt oscillates to the left and right, but
it takes longer to move toward one side or
the other, the belt oscillation needs to be
adjusted. Proceed to Step 9.
9.
Loosen the oscillation adjustment knob.
—If the belt oscillates more slowly toward
the left side of the upper roller (facing the
front of the machine), turn the oscillation
adjustment knob to the left, then tighten the
knob. This will make the belt oscillate more
quickly toward the left side.
—If the belt oscillates more slowly toward
the right side of the upper roller (facing the
front of the machine), turn the oscillation
adjustment knob to the right, then tighten
the knob. This will make the belt oscillate
more quickly toward the right side.
10. Continue observing the oscillation of the
sanding belt and adjust the oscillation adjust-
ment knob as needed until it takes the belt
approximately an equal amount of time to
move back and forth.

11. If the belt still is not tracking correctly, clean
out the dust trap (see Page 38 for instruc-
tions).
12. Verify that the air diaphragm assembly switch

A. With the motors OFF, place one finger
in front of the air jet to block the air flow.
Place another finger over the exhaust
port on the diaphragm assembly (see
Figure 53).

Figure 53. Upper bolt on diaphragm assembly.
B. When you remove your finger from the
air jet stream you should feel a puff of air
on the finger that is over the exhaust port
and you should see the upper roller pivot.
This indicates that the switch is working
correctly.
—If you do not feel a puff or air, the switch
may not be working and may need to be
replaced.
