Evolver Solventborne Robotic Atomizers - Maintenance
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 appropri-
ate sources. Be certain to wipe off all residual solution using a non-conductive solvent such
as Naphtha.
