The sanding belt oscillation speed/timing is
adjustable and controlled by control knobs on a
pneumatic cylinder (see
Figure 59). The control
knob on the right affects the sanding belt travel as
it moves toward you (when facing the pneumatic
cylinder), and the control knob on the left affects
belt travel as it moves away from you. The goal is
to adjust these knobs so it takes the same amount
of time (approximately 2–3 seconds) for the sand-
ing belt to travel in each direction as it oscillates.

Different oscillation speeds yield different sanding
results. We recommend trying various speeds on
a scrap piece of wood similar to the workpiece
being used. The oscillation speed is measured by
how long it takes the belt to move from one side
to the other.
Adjusting Oscillation Speed/Timing
T ools Needed Qty
Flat Head Screwdriver #2 .................................. 1
Door Latch Key 8mm ......................................... 1
To adjust oscillation timing/speed:
1. DISCONNECT MACHINE FROM POWER!
2. Open upper right access door.
3.
Loosen knurled jam nut (see
Figure 60) that
corresponds to the oscillation direction you
intend to adjust.
— The right jam nut and speed control knob
control oscillation speed as belt moves
toward you (when facing the pneumatic
cylinder).
— The left jam nut and speed control knob
control oscillation speed as belt moves
away from you (when facing the pneu-
matic cylinder).
5. Repeat Steps 3–4 for other speed control
knob, making sure to adjust both knobs
equally.
6. Connect machine to power and test oscilla-
tion speed, then repeat Steps 1–5 as needed
until you are satisfied.

4. Rotate speed control knob (see Figure 60)
clockwise to decrease oscillation speed,
or counterclockwise to increase oscillation
speed, then tighten jam nut to secure.
