III. OPERATION

Select the Impact Mode

The tool has an impact mode selection feature. By pressing the impact mode button, the impact strength can be selected according to Hard, Medium or Soft. Pressing the button toggles the mode from Hard → Medium → Soft. (The factory default setting is the Hard impact mode.)

In the Soft impact mode the torque is lower to prevent damaging material caused by overtightening. This mode is recommended when you wish to minimize possible damage to small screw heads or to a soft material surface to be fastened by controlling the variable speed control trigger.

The Medium impact mode also has a lower torque setting to help prevent damage to materials caused by overtightening. This mode is recommended when you wish to minimize possible damage to screws and screw heads.

The Hard impact mode is for selecting maximum torque and rotational speed.

CAUTION:

Do not press the impact mode button before rotation has stopped completely.
