How to mount Altaros regulator

Drain all air from airtube and unscrew coupler between airtube and barrel. Unscrew airtube and unscrew manometer too, deflect manometer and unscrew bolt under him.
Replace original air chamber with new one which is send with regulator. Screw this new air chamber in such depth that from top of valve to top of this new air chamber is distance 7,9mm.
By doing this and screwing it in right position you set optimal spring preload. Screw small bolt under manometer so new air chamber can not be unscrewed anymore. Put manometer back in original position and screw manometer holder. Check inside of airtube and o-ring on regulator, all should be clean without any damage. Spray thread inside of airtube and o-ring on regulator with silicone spray. Push regulator inside airtube (brass regulator towards quickfill). Then push air chamber in airtube too. It should be pushed in such depth that you see approximately half of the inner thread inside of airtube. Take air chamber out and put it next to the valve, attach airtube and start screwing airtube back on airgun valve. By screwing it back ( with air chamber inside ) you get your regulator in right position. Installation is complete.

Before filling is needed stretch cocking lever rifle, otherwise air will still pass through the barrel. When filling is necessary to fully open the valve diving bottle until in airtube is 70bar or more, then it is possible to fulfill the normal speed.

Setting pressure of airgun regulator

Altaros regulator output pressure can be set from 100bar (1450 PSI) to 150bar (2200 PSI). For a quick setting is on regulator engraved scale according to which the desired output pressure can be set. The total scale range of 100-150bar corresponds to approximately 1/2- turn. Unscrewing, or screwing setting screw more than 1 turn may result in a malfunction of the regulation and scale will not show you regulated pressure. Groove on red marked half of setting plastic screw represent pointer which shows you currently set pressure on scale. To change the pressure on regulator, just simply rotate the set screw with the flat screwdriver in the appropriate direction according to regulator scale.

Recommended output pressure to 16 J is in the range of 100 to 120 bar.
