Indication lamp
► Fig.5: 1. Indication lamp
The indication lamp lights up green when the tool is
plugged. If the indication lamp does not light up, the
mains cord or the controller may be defective. The indi-
cation lamp is lit but the tool does not start even if the
tool is switched on, the carbon brushes may be worn
out, or the controller, the motor or the ON/OFF switch
may be defective.
Unintentional restart proof
Even locking lever keeping the switch trigger depressed
(Lock-on position) does not allow the tool to restart even
when the tool is plugged.
At this time, the indication lamp flickers red and shows
the unintentional restart proof device is on function.
To cancel the unintentional restart proof, pull the switch
trigger fully, then release it.
Soft start feature
These models begin to run slowly when they are turned
on. This soft start feature assures smoother operation.

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.

wheel, be sure to use only the special wheel
guard designed for use with cut-off wheels. (In
European countries, when using a diamond
wheel, the ordinary guard can be used.)
