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 other airguns. Do not use pin as a lever for tightening regulator. For that is added screw-in spare o-rings.

Setting output pressure on regulator

What to do when your output pressure increasing over time? This is most likely caused by dirt on o-ring on plastic screw.

In this video is shown how remove dirt and replace o-ring . In video is used Gunpower regulator. Procedure is same for other regulators.

Installation instuction for Airgun Kral Arms Puncher Jumbo rifle pressure regulator

This section is too narrow and Altaros regulator can not go through it

There is need to grind and enlarge this section to around 32mm  ( regulator has diameter 31,4 mm )

When is narrow section grinded enough you can screw regulator in valve.

Before unscrewing airtank from valve we need to drain all air from it.

Mount Altaros regulator

Screw regulator on plug. We have to be sure that the regulator has in the groove the o-ring. 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 manometr 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 a bad position you can insert a black nylon ring in place o-ring. This changes the position after screwing.

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 170bar (2500PSI) which corresponds to the rotation of the screw behind value 150bar 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.

Filling and draining air

NEVER fill air through the valve on airtube, but always fill through quick fill on regulator. 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 bar per second. According to the type of bottle can be pressurized up to 250 bar (3600 PSI). After filling to set pressure drain air from hose and disconnect paintball coupler.

Unfortunately, Kral Arms as the only manufacturer has decided not to use standards of quick couplings and uses special ones that are not compatible with any other quick coupler on the market (Daystate, FX, Hatsan, HP compressor, etc).

For filling with our regulator it is necessary to use a standard female quick coupling.

You must keep maximum cleanness in the entire pressure system (airtube and outer o-rings). Do not disassemble the regulator without previous approval, which will be awarded based on e-mail correspondence, where you provide the reason why it would be necessary to disassemble the regulator. In the case of a breach of this procedure you may damage the regulator function (fully assembled regulator is not simple and it is necessary to follow the correct procedure).
