Precautions for Maintenance, Inspections, and Adjustments

	Be sure that hydrogen gas leak check equipment is always available, and regularly perform leak checks on the hydrogen gas line. You are recommended to install a hydrogen gas alarm in the room where the instrument is located.

	Perform a leak check after reconnecting tube joints or hydrogen gas supply joints. Failure to do so can cause serious accidents, such as fires or explosions.

	Stop the supply of hydrogen gas when the instrument is not being operated. Failure to do so can cause serious accidents, such as fires or explosions.

NOTE
You are recommended to install a hydrogen gas alarm in the room where the instrument is located.
