The lever is simply a fork that slides a flat piece of cast iron left to right. The lever can be tightened if it's sloppy up and down. Under the stove is a 10mm nut that secures the lever.

The air control is sloppy on my F600 also. Just the way it is designed and nothing to be too concerned about.

Mine too, likely designed that way to allow the slider to overcome stiction. That's my guess at least!

On my Oslo the air control lever has a bunch of play to it, is this common? I was also wondering if it is, is there a way to tighten it? Just seems like it is more of a guess when when shutting down the air.

I always try to adjust mine from the closed to the open position. I go all the way closed and then open to where I want it. 2nd year burning with it and still question if I am getting it the same all the time. Good luck

What eyefish said... When shutting down for a long cruise, go full shut, then open a smidge to your desired setting.

Does your stove have the little access panel just inside the door, so you can get into the air control area? If so, there is a way to maybe tighten it up a bit. The air control is a cast plate with two large windows or shutters, which slides back and forth over corresponding holes in the plenum below to control airflow. There are two little tits sticking up from this plate, and the rear arm from your air control lever sits between them. If you can lower the position of the arm, it will remove some slop. The best way to do that on my stove, is to get the arm to sit one thread lower on the set screw pivot (accessible from ash door). This is not always possible, though, and your only remaining option is to just bend the arm down slightly. Be careful to make sure you can still get the full range of motion without jamming full open or full shut, if you do that.
