Installing or removing wheel guard
(For depressed center wheel, flap
disc, flex wheel, wire wheel brush
/ abrasive cut-off wheel, diamond
wheel)
WARNING:
When using a depressed center wheel,
flap 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.
WARNING:
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.)
Mount the wheel guard with the protrusions on the wheel guard
band aligned with the notches on the bearing box. Then rotate
the wheel guard to such an angle that it can protect the opera -
tor according to work. Be sure to tighten the screw securely.

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