5. Tighten the lock nut
(
Figure 27)
to secure
the airflow adjustment knob.
6. Restrict the airflow across the air fork gap
with a scrap piece of wood. You should
notice the roller pivot to the right. When the
stick is removed, the roller should pivot back
to the left.
7. Test the oscillation by running the sander.
Make note of the time it takes for the belt to
osc
illate from left-to-right and from right-to-
left.
When correctly timed, the oscillation should
take a similar amount of time to oscillate.
—If the oscillation time to the right is 2 sec-
onds, but the oscillation time to the
left is
longer, loosen the oscillation adjustment
knob (
Figure 28) and move it to the left until
proper tracking is achieved. Tighten down
the oscillation adjustment knob when satis-
fied.
Figure 28. Oscillation adjustment knobs.
—If the oscillation time to the left is 2 seconds,
but the oscillation time to the right is longer,
loosen the oscillation adjustment knob and
move it to the
right until proper tracking is
achieved. Tighten the oscillation adjustment
knob when satisfied.
8. Continue to the next page to adjust the oscil-
lation speed.
