Unscrew airtube + cleaning

Drain all air from airtube. Remove coupling between airtube and barrel. Unscrew airtube from airgun and clean o-ring and inside of the airtube. For cleaning, we use a foam or lint free cloth. It is good to wash out the inside of the airtube with degreaser, or technical petrol, etc..

Mount Altaros regulator

Remove the O-ring from a plug. Spray regulators o-ring from the outer side with silicone spray. Insert regulator into airtube so that it is possible to screw the brass plug and check the presence of the lower O-ring in the groove. By screwing plug we get regulator into correct position. Don't screw plug to the max, but leave a gap (between plug and airtube) about 0.5 mm

Filling and draining air

Fill airtube with air through quick fill. After proper installation should gauge on airgun show regulated pressure, for the filling always use a filling set with an external gauge, so that you have an overview of the real pressure in the airtube.

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.
