Installing or removing wheel guard
(For depressed center wheel, multi disc, wire
wheel brush / abrasive cut-off wheel,
diamond wheel)
WARNING:
•
When using a depressed center grinding
wheel/Multi-disc, flex wheel or wire wheel brush,
the wheel guard must be fitted on the tool so that
the closed side of the guard always points toward
the operator.
•
When using an abrasive cut-off / diamond wheel,
be sure to use only the special wheel guard
designed for use with cut-off wheels. (In some
European countries, when using a diamond wheel,
the ordinary guard can be used. Follow the
regulations in your country.)
For tool with locking screw type wheel guard

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 to such an angle that it can
protect the operator according to work. Be sure to
tighten the screw securely.
To remove wheel guard, follow the installation
procedure in reverse.
