010864 

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.
