8 ENGLISH
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.
You can change the impact force within approximately
one minute after releasing the switch trigger.
Hard, Medium, and Soft impact mode allows a tighten-
ing suitable to the work.
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.
