I asked Dennis at IndianaAirguns.com to get a diagram for the Hatsan Bully. As usual, he came through for me. To enlarge the image, right click and select Open Image in New Tab

There seems to be one on the gun's left side - a tiny round knob just ahead of the cheek rest with 1-2-3 markings on it."cootertwo"There is no power adjuster knob.
"PelletPusher"Rich, how does the power adjuster knob function in the Bully? Does it change the port size, hammer spring, or something else?
"Imold"Thanks for the diagram Rich I copied it for later reference, now I only have two more days until my Bully .30 gets here.

The only power adjustment on mine (25 cal) is the hammer spring tension screw and I have to remove the stock to get at it. Can you post a photo of what you're looking at?
Thanks,
Rich
I have seen several videos from different YouTubers with the same power adjuster knob. Check out other videos especially in Turkish language."Rich7777"The Bully in the video has been modified. That dial isn't factory. Judging by the location, I would say that's a transfer port restriction.
