The Airgun Regulator is the same as regulator for rifles gunpower, the only change is that in the package is also nylon spacer ring, which is used in the case when gauge and filling pin is not in a good position. It is a simple installation without adjustments on rifle, so everything can be returned back. All you need to do is unscrew the bottle from airgun body (before screwing launch air). Then screw regulator between the bottle and airgun body. After installing the regulator NEVER fill by quick fill on the airgun, only by quick fill on regulator. For the filling you must purchase paintball coupling, which is the same as gun marauder or more. Do not use pin as lever for tightening regulator. For that is added screw-in spare o-rings.

Then screw the regulator back into the bottle and check again presence of o-ring in the neck of the bottle. Check the o-rings (cleanliness, if they are without damage) on filling pin and manometer. Pin and manometer screw-on regulator only with fingers, screw them so much that the upper larger cylinder of manometer and pin are touching regulator perimeter. Slot for pin and manometer can be changed depending on where you get more comfortable with his position, You can make a small correction and unscrew bottle little bit (no need to complete attachment to the wall). When your manometer and pin has bad position you can insert black nylon ring in place o-ring. This changes the position after screwing.

Filling and draining air

NEVER fill air through the valve on airtube, but always fill through quick fill on regulátor. If it is all ok, connect Paintball coupler and fill airtube. Be sure that paintball coupler ball lock is fall in. First filling make slowly around 2-3 per second Bar. According to the type of bottle can be pressurized up to 250 bar (3600 PSI).

Setting pressure of airgun regulator

Altaros regulator output pressure can be set from 100bar (1450 PSI) to 150bar (2200 PSI) and after consultation of up to 170 bar (2500 PSI) which corresponds to the rotation of the screw behind value 150 bar so that the line of the screw is pointing to the letter R. 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 2/3 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 represents pointer which shows you currently set pressure on the 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.
