There are three brass thumb nuts/ knobs on the leveler for two of the studio cameras. As these devices are new, they are a bit tight, and hard to turn.

To make leveling easier, lift slightly on the base of the camera. This will take some weight off of the screw and nut, and allow it to turn a bit easier.

Look at the bubble level on the tripod head to see if you’re level.

Once the thumbscrews have been used for a while they should loosen up enough to make leveling easier.

When you have leveled the camera, thread the lower nut up as a lock to the levelling thumbscrew.

Finger tight is tight enough! Don’t use any tools in adjustment of the brass screws/knobs.

Let me know if you need further in instructions! –Rad
