Grizzly G8622 instruction manual Belt Tension, Speed Changes, Fence Adjustment

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 2-3until 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.

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.

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.
