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
Fig.4
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.
For tool with clamp lever type wheel guard

Fig.6
Loosen the lever on the 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 around to the position shown in the
figure. 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 nut by spanner to adjust the
tightening of the wheel guard band.
To remove wheel guard, follow the installation procedure
in reverse.

OPERATION
WARNING:
•
It should never be necessary to force the tool. The
weight of the tool applies adequate pressure.
Forcing and excessive pressure could cause
dangerous wheel breakage.
•
ALWAYS replace wheel if tool is dropped while
grinding.
•
NEVER bang or hit grinding disc or wheel onto
work.
•
Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
•
NEVER use tool with wood cutting blades and
other sawblades. Such blades when used on a
grinder frequently kick and cause loss of control
leading to personal injury.
