How To Attach And Detach The Connecting Part
■ How to attach and detach the tube
1. Attaching the tube
Insert the tube through the cap nut up to the barb base. Then, tighten the cap nut over the tube by hand until it touches the metal body.
2. Detaching the tube
To remove the tube, manually remove the cap nut. Then remove the tube.
Whenever detaching the tube, be sure to turn off the air before proceeding.
■ How to tighten the screws
There are two ways to tighten the screws: by tightening the outer hexagon with a wrench, or by using a straight-slot screwdriver in the groove on the top of the hexagon (this lets you minimize the space between fittings).
Also refer to the table below when tightening the screws.
