Oscillation Speed

The oscillation speed of the sanding belt is adjustable. Different oscillating speeds yield dif- ferent sanding results. We recommend trying various speeds on a scrap piece of wood similar to the final workpiece.

To adjust the oscillation speed:

1.Loosen the lock nut on the speed control adjustment knob (Figure 30).

2.Turn the knob clockwise to decrease the oscillation speed and counterclockwise to increase it.

3.Tighten the lock nut loosened in Step 1 to secure the knob.

Table Parallelism

NOTICE

The table has been adjusted at the fac- tory and should require no further attention. However, we recommend verifying that it is parallel with the sanding roller.

The corners of the table can be independently adjusted up or down. By disconnecting the chain and turning the pertinent table elevation screw sprocket, (Figure 31) table parallelism can be achieved.

Adjusting the table parallelism can be a very tedious task that takes a great amount of patience. DO NOT adjust the table unless you are having trouble sanding your workpiece to a uniform thickness.

If a table adjustment is needed, take precise notes on the positioning of the table elevation screws. This will allow the original setting to be re-established.
