G9983 15" Open-End Wide-Belt Sander

Figure 20.

This is the oscillation

timing control knob.

5.

When you get the belt to oscillate without
stopping, experiment with the timing knob to
see the effect its movement has on the belt
oscillation.

6.

Position the timing knob so the belt moves
from one side to the other, back and forth, in
even intervals.

7.

Lock the knob in place by turning it clock-
wise.

Long term exposure to
this machine during
operation may cause
hearing loss. Wear
approved hearing pro-
tection to minimize this
risk!

Oscillation Speed

Figure 21.

Use the knob on this valve to control

oscillation speed.

Use the valve shown in

Figure 21

to control the

speed of the sanding belt oscillation. Make sure
the oscillation is balanced before adjusting the
speed.

To increase the oscillation speed

, open the

valve (turn the knob counter-clockwise). For nor-
mal operation, adjust the oscillation speed so
each direction of belt movement takes approxi-
mately 2 seconds. When the speed is correct,
tighten the jamnut so the knob will not move.

To decrease the oscillation speed

, close the

valve (turn the knob clockwise). When the speed
is correct, tighten the jamnut.

Different speeds may yield different finishing
results. Experiment with trial-and-error to deter-
mine the best speed for your particular situation.

Keep loose clothing out
of the way of moving
machinery and keep
long hair pulled back.
