Note: To check for fluid leaks, it is easiest to first remove the gun from the test station and remove the shroud
from the gun. The aluminum flange can be reattached to the gun manifold plate by using the three stainless
steel screws. Then the gun can be remounted to the test station. Leak detector may be used at all appropriate
sources. Be certain to wipe off all residual solution using a non-conductive solvent such as Naphtha.
