Pressure regulator for Hatsan Hercules helps stabilize the performance of the rifle. It is identical to the regulator for Gunpower rifles. A nylon O-ring is also supplied, which is used in case of an incorrect position of the filling pin and the manometer.
The regulator is relatively easy to install. Simply make sure the air is released from the cylinder, unscrew it from the rifle body and screw the regulator between the cylinder and the rifle body. After installing the regulator, use only the Quick Fill valve on the regulator. For filling, you need to purchase a paintball quick coupler, the same as for the Marauder rifle and others.
Setting the air pressure is very simple. The groove in the red semicircle serves both as a screw and as an indicator of the value between 100 and 150 bar. Just turn the screw with a screwdriver to the desired position. Adjustment is carried out only on a dismounted regulator.
