Always wear eye and ear protection and stand clear of the discharge port when testing the relief valve to prevent injury.

CAUTION: Never paint, lubricate or alter a pressure relief valve. Do not plug vent or restrict discharge.

DANGER: Operation of the unit with improper pressure relief valve setting can result in severe personal injury or machine damage. Ensure properly set valves are installed and maintained.
