Changing the impact force (Fig. 7)
015147
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
is pressed, the number of
blows changes in four steps.
You can change the impact force within approximately
one minute after releasing the switch trigger.
“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.
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.
• 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.
Indicating the remaining battery capacity (Fig. 8)
(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.
015191
NOTE:
• Approximately one minute after the motor stops, the
indicators go off to save the battery power. To check
the remaining battery capacity, slightly pull the switch
trigger.
Tool / battery protection system
The tool is equipped with a tool/battery protection
system. This system automatically cuts off power to the
motor to extend tool and battery life.
The tool will automatically stop during operation if the
tool or battery are placed under one of the following
conditions. In some conditions, the indicator lights up.
