• Rotation only
Set the change lever to the "Rotation only" ( mark) position.
The claw of the bevel gear engages with the claw of the clutch. Rotational force is transmitted to the
cylinder coupled with the clutch and rotates the bit. The slide sleeve moves to the front end side as the lock
sleeve moves there. This keeps cylinder air hole B open. As a result, air pressure inside the air chamber
remains the same and hammering force is not transmitted.
• Neutral
This product has a Neutral mode to be used to determine the working position of a bit tool such as a cold
chisel.
Set the change lever to the "Neutral" ( mark) position.
The bevel gear disengages from the clutch and cuts off the transmission of rotational force. The lock sleeve
also disengages from the clutch so that the cylinder can rotate freely. In this state, the user can turn a bit
tool to the desired working position.
