For those of you who’d like to adjust your regulators; this holds true for about every reg I’ve messed with, including a Huma that loses the graduated label.
*Disclaimer: If you get lost in your tinkering it will be very frustrating. Don’t make huge adjustments without testing small changes first. It’s on you.
After pulling the reg, make a mark on the adjuster and a mark on the reg body that lines up. Think of this as the 12 o'clock position, with the mark on the body being the hour and the mark on reg adjuster being the minute.
Counterclockwise adjustments increase pressure and clockwise adjustments decrease pressure. Each minute equals 2 bars ~ 5 minutes or 10 bar equal about 25 fps.
Now, as you begin testing over the chrony, find the highest fps with the hammer spring adjuster. This can be found by dialing in HST clockwise by 1/2 turn increments. As the jumps in speed begin to get small, use 1/4 turn increments. When the speed no longer increases after a few 1/4 turn increments or the speed actually goes down, this is when you’ve found the highest speed that this given reg setting can produce. This is your plateau. Now dial back counterclockwise until you’ve subtracted 1.5% to 2.5% from this plateau. Some guns like a smaller differential than others. Testing will indicate.
P.S. The Taipan regs are a bit different and these PCPs can perform well with up to a 3.5% differential. Watch Ernest Rowe’s video on them. Each hole of adjustment equals about 2 bar ~ 5 holes or 10 bar equal about 25 fps.

Anyway, it was a little distracting shooting the Uragán with a throbbing pinky 
Good luck getting your hands on one though!
