on Page 25.
2. Make sure there are no obstructions around
or underneath the spindle.

the mill/drill to the power source
.
5. Turn the main power switch ON, and push
the START button on the control panel. The
spindle will begin to turn at a low RPM.
6. Now push the + button until the mill/drill
reaches approximately 600 RPM, then let it
