Changing assist type
This tool employs assist function that offers several easy-to-
use application modes for driving screws with good control.
The type of the application mode changes every time
you press the button
Application mode
(Assist type displayed
on panel)
Wood mode *1
Bolt mode (reverse rota-
tion auto stop) *1 *2
T mode (1) *1
T mode (2) *1
*1 : Automatic speed control works only when the switch trigger is fully pulled.
*2 : Reverse rotation auto stop works only when the tool is driving in counterclockwise rotation.
NOTE: When none of the lamp on the panel is lit, pull the switch trigger once before pressing the button
NOTE: All lamps on the switch panel go out when the tool is turned off to save the battery power. The type of the
application mode can be checked by pulling the switch trigger to the extent that the tool does not operate.
Quick mode-switching function
What you can do with the quick mode-
switching function
The quick mode-switching function saves the time for changing
the application mode of the tool. You can switch to your desired
application mode by just pressing the quick mode-switching
button. It is helpful when doing a repetitive work which requires
to switch between two application modes alternately.
EXAMPLE If you have a work to use T mode and max
impact force, register the max impact force for quick
mode-switching function. Once register it, you can switch
to the max impact force from T mode by just one click of
the quick mode-switching button. Also, you can return to T
mode by pressing the quick mode-switching button again.
Even if the tool is in other application mode than T
mode, pressing the quick mode-switching button
changes to max impact force. It is convenient for you
to register a application mode that you frequently use.

Maximum blows
-1
3,800 min (/min) This mode helps to prevent a screw from falling at
the beginning of driving. The tool drives a screw
with low-speed rotation at first. After the tool starts
to impact, the rotation speed increases and reaches
the maximum speed.
-1
3,800 min (/min) This mode helps to prevent a bolt from falling off.
When loosening a bolt with the tool driving in coun-
terclockwise rotation, the tool automatically stops
after the bolt/nut gets enough loosened. The stroke
of the switch trigger to reach maximum speed will
become short in this mode.
– This mode helps to prevent the screws from
(The tool stops rotating over-tightening. It also accomplishes quick oper-
soon after impact starts.) ation and good finish at the same time. The tool
drives a screw with high-speed rotation and stops
soon after the tool starts to impact.
NOTE:
The timing to stop the driving varies depending
on the type of the screw and material to be
driven. Make a test driving before using this
mode.
-1
2,600 min (/min) This mode helps to prevent the screws from
breakage and stripping. It also accomplishes quick
operation and good finish at the same time. The tool
drives a screw with high-speed rotation and slows
down the rotation when the tool starts to impact.
NOTE:
Release the switch trigger as soon as the tight-
ening finished to avoid overtightening.
You can change the assist type within approximately
one minute after releasing the switch trigger or press-
ing the button
button.
