ASSEMBLY
WARNING:
Always install a grinding wheel with the depressed

injury because of loose particles breaking off and
being thrown from the grinder. Do not overtighten.

the nut facing up.
„ Fit the raised, small diameter portion of the flange nut
into the hole in the wheel and finger tighten.
„ Depress the spindle lock button and rotate the wheel
clockwise until the spindle locks in position.
