WARNING

- Attach a valve (for stop in emergency) or regulator to the air supply pipe to keep supply air pressure
under 0.7MPa.

- Be careful not to drop the cabinet when lifting it up to replace a pail. Catching a falling cabinet may
cause hand injury by its edge.

malfunction.

- Do not aim exhalation part of this product at any person. Residual pressure may be left inside the gun
even when the pump is not in operation. There is a possibility of losing eyesight if it strikes eyes.

- Before maintenance operation, be sure to stop air from being supplied to the pump, and release the
internal pressure (both air and material) of the pump. There is danger such as spouting of the material
when the maintenance work is done with air supplied.

- Gasoline is a high volatile fuel. Do not use it to clean the pump in any case, otherwise ignition or
explosion may be caused.
