Now look at the regulator. Inspect the small black rubber ‘O’-ring on the regulator for any damage. If damaged the ‘O’ ring should be replace.
To connect the regulator to the cylinder, slide the brass end of the regulator into the outlet on the cylinder. Note this image is looking down on the vertical gas cylinder.
To fasten the regulator to the cylinder, slide the large brass hexagonal nut onto the threaded part of the gas cylinder outlet..
Hold the regulator firmly with one hand and hand-tighten by screwing the hexagonal nut onto the cylinder thread. You do not need a wrench or other tool to fasten the regulator to the cylin- der.
Fig: Atatching the regulator to the cylinder:
If you cannot fasten the regula- tor tightly to the cylinder by hand, you can use a wrench but do not over-tighten.
The regular should not be loose or easily rotatable on its axis. To change the angle of the display of the screen on the regulator, loosen the hexagonal nut, then rotate the regulator. Complete this process by re-tightening the hexagonal nut.
