4.01 CHECKING FOR LEAKS

low pressure gauge drops, there is a leak in the torch handle
valve, hose, hose fitting, outlet fitting, or low pressure gauge.
If the high pressure gauge drops, and at the same time the low
pressure gauge rises, there is a leak in the regulator seat. Have
a qualified repair technician repair the regulator.
