■ Place the accessory wheel over the spindle.
WARNING:
Always install grinding wheel and abrasive mop disc with
the depressed center against the disc flange as shown
above. Failure to do so will cause the grinding wheel to
crack when tightening the clamp nut. This could result in
serious personal injury because of loose particles breaking
off and being thrown from the grinder. Do not overtighten.
■ To install grinding wheel and wire wheel brush: Thread
the clamp nut on the spindle with the flat side of nut facing
up. Fit raised, small diameter portion of the clamp nut into
the hole in the wheel and finger tighten. See figures 3A
and 3B.
■ To install abrasive mop disc: Thread the clamp nut on the
spindle with the flat side of nut facing down. Finger
tighten. See figure 3C.
■ Depress the spindle lock button and rotate the wheel
clockwise until the spindle locks in position.
■ Securely tighten the clamp nut with the wrench provided.
Do not overtighten.
WARNING:
Wire wheel brush bristles will bend during use and show
their direction of rotation. When reusing the wire wheel
brush, always mount it to rotate in the same direction as
in prior use. Failure to heed this warning can result in
bristle breaking and extreme vibration of the wire wheel
brush that could result in serious personal injury.
