2021 LOCKDOWN - Our Online Store & Service Workshops are still OPEN as usual
If you have one of our new Easy Fit HWT 250bar Titanium Cylinders, you will probably never need to adjust the in-tube regulator.
If you have our 250bar Titanium Cylinder & Pre-Chamber Insert, follow these instructions:
Before you start, make sure that the rifle is unloaded, remove the magazine and make absolutely sure that ALL of the air has been drained from the cylinder. The pressure gauge will give you just an indication - dry fire the rifle until all of the air is drained.
just turn the setscrew clockwise to the pressure you desire. Never turn the setscrew past the lowest or highest mark on the scale!
This is slightly different; turn the setscrew anti-clockwise until you are about 10bar ABOVE the pressure you want, then turn the setscrew back DOWN (clockwise) to the pressure you want. (This is necessary to eliminate the movement on the treads). Never turn the setscrew past the lowest or highest mark on the scale!
The reg is set on 130bar and you would like to set it to 140bar. First, turn the setscrew anti-clockwise to 150bar, then turn clockwise to the 140bar you are aiming for.
Inside the bronze setscrew is an m3 allen screw. It works as a flow restrictor and prevents dirt getting into the regulator. It's turned in until the end and then screw 2 turns it backwards.
The regulator is equipped with a pressure scale on the neck and a set mark on the top of the bronze setscrew. This enables you to re-adjust or fine-tune your regulator exactly to your wishes. The picture shows the set mark pointing to 140bar.
Do not attempt to fit this regulator in a different rifle, it has been custom made to fit inside the HW100Tuning Titanium Cylinder End Cap, not just inside the tube - this maximises air cylinder capacity, to give as many shots per fill as possible.
