2. Turn cam lever so the motor pulley moves toward the center pulley.
3. Select the proper speed by referring to the chart inside the pulley cover. Move the belts
into corresponding position for the selected speed.
4. Rotate the cam lever so the motor puiiey moves away from the center pulley and tightens
the belt.
5. While holding tension on the cam lever, tighten the locking screws on both sides of the
head.
6. Close the cover.
Note: The speed chart under the pulley cover reflects two different power cycles for the
motor. Use the 60 cycles per second spindle RPM in the USA.
C. SPINDLE ADJUSTMENTS

lower the spindle to the desired depth and tighten the scale setscrew.
To hold a stationary depth, loosen the scale setscrew, and rotate the feed shaft to its lowest
