How to Replace the Lens
① Remove
Remove the Air Assist Nozzle first, then loosen the Brass Lense Nut with a Lens Tool,
pay attention to the rotation direction of the wrench, and take out the old seal ring and lens.
② Install
The notched side of the Brass Lense Nut faces up. Pay attention to the order in which you put it in.
Then tighten it with a Lens Tool, but do not use too much force, or the lens may be damaged.

②
The side with red spots on the lens faces outward.
These three parts can only be tightened after they are placed flat,
otherwise the lens will be broken!
