Installing or removing wheel guard
CAUTION:
When using a depressed center grinding wheel/Multi-
disc, flex wheel, wire wheel brush or cut-off wheel, the
wheel guard must be fitted on the tool so that the closed
side of the guard always points toward the operator.
Mount the wheel guard with the protrusion on the wheel
guard band aligned with the notch on the bearing box. Then
rotate the wheel guard around 180 degrees. Be sure to
tighten the screw securely.
To remove wheel guard, follow the installation procedure in
reverse.
Installing or removing depressed center grinding
wheel/Multi-disc
WARNING:
Always use supplied guard when depressed center
grinding wheel/Multi-disc is on tool. Wheel can shatter
during use and guard helps to reduce chances of
personal injury.
Mount the inner flange onto the spindle. Fit the wheel/disc on
the inner flange and screw the lock nut onto the spindle.
To tighten the lock nut, press the shaft lock firmly so that the
spindle cannot revolve, then use the lock nut wrench and
securely tighten clockwise.
To remove the wheel, follow the installation procedure in
reverse.
