To prevent hazardous concentrations of toxic
and/or
flammable vapors, spray only in a properly
ventilated
gun unless ventilation fans are operating.
Check and follow all of the National, State and

and the distance from the workpiece.
Connect the Fluid Line
1. Before connecting the fluid line, blow it out with air
and flush it with solvent. Use solvent which is compatible
with the fluid to be sprayed.
2. Install
a fluid regulator on the fluid line to control fluid
pressure
