Cleanup
Maintaining a clean gun is important to ensure trouble-free operation. Flush the gun after each use
and store in a dry location. Do not leave the gun or any of its parts in water or solvents.
Special cleanup instructions for use with
flammable solvents:
• Always flush spray gun preferably outside and at least one hose length from spray pump.
• If collecting flushed solvents in a one gallon metal container, place it into an empty five gallon
container, then flush solvents.
• Area must be free of flammable vapors.
• Follow all cleanup instructions.
Attention
The sprayer, hose, and gun should be cleaned thoroughly after daily use. Failure to
do so permits material to cake, seriously affecting the performance of the unit.
Always spray at minimum pressure with the tip and tip guard
removed when using mineral spirits or any other solvent to clean
the sprayer, hose, or gun. Static electricity buildup may result in a
fire or explosion in the presence of flammable vapors. Hold the
gun firmly against a metal container while flushing.
Maintenance
Follow all safety precautions as described
in the Safety Precautions section of this
manual before proceeding.
