This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for coun-
terclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
A mode
“A mode (assist mode)” is an easy-to-use mode for
driving screws with good control.
In this mode, the tool drives a screw with low-speed
rotation at first. After the tool starts to impact, the rota
-
tion speed increases and reaches the maximum speed.
To turn on A mode, press the button
on the panel.
Pull the switch trigger to start driving in A mode.

You can change the impact force in five steps: max
-
,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 five steps.
“T” is a special mode for fastening self drilling screws.
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 medium force grade.
You can change the impact force within approximately
one minute after releasing the switch trigger.

NOTE:
T mode and A mode is available only when the tool rotates clockwise. When rotating counterclockwise in T
mode and A mode, the impact force and speed are the same as max mode.
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.
NOTE:
While pulling the switch trigger, the impact force grade cannot be changed.
