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 indication 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.
