Installing or removing wheel guard (For
depressed center wheel, multi disc/
abrasive cut-off wheel, diamond wheel)
WARNING:
• When using a depressed center grinding wheel/Multi-
disc, flex wheel, wire wheel brush, cut-off wheel or
diamond wheel, 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 clamp lever type wheel guard
Loosen the lever on the wheel guard after loosening the
screw. 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. (Fig. 7)
Tighten the lever to fasten the wheel guard. If the lever is
too tight or too loose to fasten the wheel guard, loosen or
tighten the screw to adjust the tightening of the wheel
guard band. (Fig. 8)
To remove wheel guard, follow the installation procedure
in reverse.
