NOTE: A mode is available only when the tool rotates clockwise. When rotating counterclockwise in A mode, the
impact force and speed are the same as hard 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.

You can change the impact force in three steps: hard,
soft, and A mode.
This allows a tightening suitable to the work.
Every time the button is pressed, the number of blows
changes in three steps.
"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.
For approximately one minute after releasing the switch
trigger, the impact force can be changed.
Purpose
Tightening when force and
speed are desired.
Tightening with less force to
avoid screw thread breakage.
Tightening screws with better
control.
