HOW THE GAUGE OPERATES
• Gauge works automatically once the cylinder is opened. When the valve is closed, the gauge returns to the O position once all the excess gas in the hose is depleted.
• In cooler environments, the pressure inside the cylinder will lessen slightly, this will have a small effect on the reading of the gauge – This is normal.
• The gauge only works when the cylinder valve is open.
• The gauge doesn’t need to be reset, the gauge returns to 0 when the gas supply has been shut off.
• When the needle approaches the YELLOW bar, this indicates that the cylinder is running out of gas. Refilling the cylinder is advisable.
