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.

You can change the impact force in three steps: hard,
soft, and Reverse rotation auto stop mode.
This allows a tightening suitable to the work.
Every time the button is pressed, the number of blows
changes in three steps.
The function of Reverse rotation auto stop mode works only with pulling the trigger fully in counterclockwise tool
rotation. When the bolt/nut gets enough loosened, the tool stops the impact and rotation.
For approximately one minute after releasing the switch trigger, the impact force can be changed.

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.
