G8622 Tilting Spindle Sliding Table Shaper -19-
Speed Changes
The Model G8622 Shaper is equipped with a V-
belt drive system that controls the speeds. To
change spindle speeds:
1. Unplug the machine.
2. Loosen the two motor plate bolts and slide
the motor toward the spindle assembly. DO
NOT take the bolts out.
3. Select the desired speed. There are four
speeds: 3600 R.P.M., 5100 R.P.M., 8000
R.P.M., and 10,000 R.P.M. Figure 27 shows
the belt positions for each available speed.

4. Align the belt along the appropriate pulley
grooves.
5. Slide the motor back into position and tight-
en the belt. When the belt is properly ten-
sioned, there should be approximately
1
⁄4" of
deflection in the center of the belt when you
press it with your thumb.
6. Tighten all of the adjustment bolts.
7. Spin the pulley to ensure proper tracking.
V-Belt Tension
You should be able to deflect the belt
1
⁄4" with
moderate finger pressure. This may seem tight
compared to most other V-belts, but since the belt
is small and runs fast, this amount of tension is
necessary. The V-belt will slip if too loose, and
will squeal or cause vibration if too tight. To adjust
V-belt tension:
1. Make sure the pulleys are properly aligned.
2. Loosen the two motor mount plate bolts and
slide the motor left or right to modify the belt
tension. Keep the pulleys aligned.
3. Tighten the motor mount plate bolts, test the
tension, and check the pulleys.
4. Repeat steps 2-3 until the tension is correct
and the pulleys are aligned.
Disconnect power to the
machine when perform-
ing any adjustments or
maintenance. Failure to
do this may result in seri-
ous personal injury.
Fence Adjustment
The fence is a two-piece adjusting system. Each
fence is independently adjustable to compensate
for different cutting thicknesses and special shap-
ing applications. Without any play, one turn of the
knob moves the split fence approximately
5
⁄64"
(.078"). To adjust the fence:
1. Loosen the fence lock handle.
2. Turn the fence adjustment knob until the
fence is set to the desired position.
3. Tighten the fence lock handle.
More detailed information concerning fence
adjustments is covered in the “Straight Shaping”
instructions.
