Sealey sg18?

Does anyone else use this wax sprayer and has any tips on how to use it such as the pressure to use and what that screw does under the trigger?
Photo attached of what it looks like, goes under different brand names too

Never saw one before. But I can assume that the screw under the trigger is a trigger stop. The shorter it is, the more air goes to the nozzel, the longer it is the less air goes to the nozzel.

Hmm, would it have anything to do with adjusting the ratio of air to product?
