OPERATIONS
Belt Oscillation SpeedFor normal operations, the oscillation speed should be
set so that it takes approximately a second or two to
completeeachdirectionoftravel;however,you can
experiment with different speeds to see how the results
may affect your finished product. Often, you may find
that certain speeds yield better results for different
varieties of stock and the feed rates chosen.
To set the belt oscillation speed, do these steps:
1. Complete the Belt TrackingadjustmentsonPage 22.
2. Putonsafetyglasses,tiebackallloose clothing,
removejewelry,pullbacksleeves,andtiebacklong
hair so it will not get caught by the sanding belt.
3. If you have not already done so, turn the sander
ON.

—If you want the belt oscillation to oscillate from
left to right in shorter and faster sweeps, loosen

knob counterclockwise (Figures 27 and 28).
—If you want the belt oscillation to oscillate from
left to right in longer and slower sweeps, loosen
thejamnutandthenrotatetheoscillation speed
knob clockwise (Figures 27 and 28).
