Ransburg Evolver Solvent Robot Applicator 79190-XXXXXXXX - Manual (Page 54)

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. 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.
