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.

ASSEMBLY
