1.DISCONNECT MILL FROM POWER!
2.Set the spindle speed range control(s) for the mill as instructed on the previous pages.
—If you hear/feel the front pulley drop into the spindle clutch when you set the control(s), this procedure is complete and you can continued with spindle speed setup.
—If you do not hear/feel the front pulley drop into the spindle clutch when you set the control(s), continue with Step 3.
