Installation instructions for Daystate air rifle pressure regulator

It is appropriate before reading the instructions look at the video instructions and then read the instructions for avoiding common mistakes during installation Daystate ( models with airtube )

Installation is simple! Drain all air form airtube then unscrew the valve body from the airtube. Spray o-rings with silicone oil, then push regulator inside airtube ( with circular movement like when you screwing valve, this movement will prevent damaging outer o-ring on regulator) in such depth so you can see ¾ thread inside airtube. Remove both o-rings from valve and screw valve back on airtube.By screwing plug back in airtube we get regulator into the correct position. Do not tight airtube and valve fully. Leave gap 0.2-0.5 mm between them, by doing this and removing o-rings from valve you creating venting hole ( with this is no drilling to airtube needed).

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.
