medium, soft, and T mode.
This allows a tightening suitable to the work.

changes in four steps.
For approximately one minute after releasing the switch
trigger, the impact force can be changed.
"T" is a special mode for fastening self drilling screws
and bolts. In this mode, the tool starts to drive a screw
with faster rotation, which is suited for drilling with the
self-drilling -screw tip. Once the tool starts to tighten the
screw, it impacts in soft force grade.

turned off to save the battery power. The impact force
grade can be checked by pulling the switch trigger to
the extent that the tool does not operate.
While pulling the switch trigger, the impact force
•
grade cannot be changed.
The tool automatically stops to prevent the
•
damages on the parts during heavy load operation
with hard or medium impact force grade. In that
case select the soft or T mode impact force grade.
