2. Loosen lock nut on airflow adjustment knob
(see Figure 76).
3. Turn airflow adjustment knob (see Figure
76) clockwise until airflow is completely OFF.
Upper roller should pivot to the right.

4. Slowly turn airflow adjustment knob counter-
clockwise, and continue turning up air pres-
sure until roller pivots left.
5. Tighten lock nut to secure airflow adjustment
knob.
6.
Restrict airflow across air fork gap with piece
of cardboard. Roller should pivot to the right.
When cardboard is removed, roller should
pivot back to the left.
7. Proceed to Equalizing Oscillation Speed to
ensure oscillation speed from left to right and
right to left are the same.
Equalizing Oscillation Speed
1.
Test oscillation by running sander. Make note
of time it takes for belt to oscillate from left
to right and from right to left. When correctly
timed, oscillation should take similar amount
of time to move in each direction.
— If oscillation time to the left is longer than
to the right, loosen oscillation tracking
knob (see Figure 77) and move it left until
proper tracking is achieved. Tighten down
knob when satisfied.
-50-
— If oscillation time to the right is longer than
to the left, loosen oscillation tracking knob
(see Figure 77) and move it right until
proper tracking is achieved. Tighten down
knob when satisfied.

Adjusting Oscillation Speed
Oscillation speed of the sanding belt is adjust-
able. Different oscillating speeds yield different
sanding results. We recommend trying various
speeds on a scrap piece of wood similar to the
final workpiece.
To adjust oscillation speed:
1. Loosen lock nut on speed adjustment knob
(see Figure 78).

2. Turn speed adjustment knob clockwise to
decrease oscillation speed and counterclock-
wise to increase.
3. Tighten lock nut to secure speed adjustment.
