Video Installation



Video chrono test Benjamin marauder with 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 others regulator.

It is appropriate before reading the instructions look at the video instructions and then read the instructions for avoiding common mistakes during installation Benjamin Marauder

Unscrew airtube

Before removing plug we need drain all air from airtube, we can shoot without pellets for drain air. Unscrew couple between airtube and barrel, than remove the plug itself. For removing plugs can be used pliers, or we can use coupling us lever.

Mount regulator

After unscrewing plug is necessary to unscrew the handle with a manometer. Screw the installation stick to the regulator and check o-ring, if is clean and not damaged. Spray o-ring with silicone spray for preventing any damage. Insert regulator handle to the bottom of airtube into center hole. Regulator handle insert only to a depth that you can see o-ring in the hole after removed manometer. Than pushing trought manometr hole on o-ring ( with wreng, or other blunt obejct that will not cause damage to o-ring) and push regulator with circular motion to the bottom.

In the event of a leak around o-ring on the handle will unregulated pressure penetrate in to regulated part and even the regulator is functioning properly, output pressure will be unregulated. This is the most common reason for poor consistency after installing the regulator, which is considered us malfunctioning regulator, which is bad consideration because error is in installation, or in uncleanness on the o-rings (which are between the regulator and the chamber, or between the chamber and handle of regulator). O-rings between the parts and regulator has to be easily squieezed between the walls (not too squashed). Remove the installation stick and screw the plug back into the airtube. Attach back coupling and everything is done. After installing regulator will be manometr still show pressure in airtube, not regulated pressure.

Guidance, extended manuals and video tutorials in english can by found on www.altaros.cz.

Set regulator

The pressure setting is done by  using a flat screwdriver in the upper part of the regulator.  When we setting regulator we rotate with  inside plastic screw with groove. The output pressure is showed by location colored grooves on the inner plastic screw. The total rotation range of the output pressure is in the range from 100 to 150 bar and is approximately 1/2 turn.

Scale is starting on 100 bar (green color) and ends on 150 bar (red color). Scale is only approximate and course times may change slightly due to fatigue disc springs. Fill the airtube to the maximum pressure which is mentioned by manufacturer.

Warning

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 breach this procedure you may damage the regulator function (fully assembled regulator is not simple and it is necessary to follow the correct procedure). For these reasons, the disassembly without previous consent,or failure exact installation procedure can not claim the warranty. Since regulator is not original part from the manufacturer’s, installation is on your own responsibility.
