Turn the adjusting knob clockwise and establish the required use pressure by referring to the low-pressure gauge. Make sure that the cylinder valve is easily accessible. 顺时针旋转调整钮,通过查看低压量表建立要求的使用压力。确认钢瓶阀门容易接近。
Never exchange the discharge ( low-pressure) gauge for one of lower pressure. The gauge may rupture if the adjusting knob is unintentionally turned too far. 禁止把排出量表换成更低压力的量表。如果无意中把调整钮旋的太远的话,量表会破裂。
