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.
NOTE:
• When all lamps on the switch panel go out, the tool is
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.
Indicating the remaining battery capacity (Fig. 9)
(Country specific)
When you pull the switch trigger, the LED display shows
the remaining battery capacity.
The remaining battery capacity is shown as the following
table.
