Changing the impact force (Fig. 7)
Impact force grade

The impact force can be changed in four steps: hard,
medium, soft, and T mode.
This allows a tightening suitable to the work.
Every time the button
changes in four steps.
"T" is a special mode for fastening self drilling screws. In
this mode, the tool starts to drive a screw with faster rota-
tion, which is suited for drilling with the self-drilling-screw
tip. Once the tool starts to tighten the screw, it impacts in
medium force grade.
For approximately one minute after releasing the switch
trigger, the impact force can be changed.
