5.Tighten the lock nut (Figure 28) 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 oscillate 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 29) and move it to the left until proper tracking is achieved. Tighten down the oscillation adjustment knob when satis- fied.
