CAUTION① Use compressed clean air within the specified pressure range.( Impurities 5μm or less.)② When a foreign object gets mixed in a pipe, it becomes the cause trouble in movement.
③ When you screw a coupling into a regulator, be careful not to get mixed with seal tape.
④ When you connect a coupling to a regulator, please be careful not to close too tight.
⑤ Please connect to the right direction.
⑥ When you attached valve inside of the regulator, the pressure of the outside may become unstable.
⑦ There is a little leak from relief-part when you use relief type.
☆If you have any question, FUJIKURA are ready to assist you. Please consult us at the address printed on the back cover.
