Important User Information
Before using your sprayer read this Operation Manual for complete instructions on proper use and safety warnings.
Congratulations! You have purchased a high-quality paint sprayer made by Graco Inc. This sprayer is designed to provide
superior spray performance with all architectural paints and coatings. This user information is intended to help you
understand the types of materials that can be used with your sprayer.
Before using this equipment, be sure to read and follow the information on your container label and ask for a Material Safety
Data Sheet (MSDS) from your supplier. The container label and MSDS will explain the contents of the material and the
specific precautions related to it.
Paints, coatings and clean-up materials generally fit into one of the following 3 basic categories:
WATER-BASED: The container label should indicate that the material can be cleaned up with soap and water.
Your sprayer is compatible with this type of material. Your sprayer is NOT compatible with harsh cleaners such as
chlorine bleach.
OIL-BASED: The container label should indicate that the material is combustible and can be cleaned up with
mineral spirits or paint thinner. The MSDS must indicate that the flash point of the material is above 100° F. Your
sprayer is compatible with this type of material. Use oil-based material outdoors or in a well-ventilated indoor area
with a flow of fresh air. See the safety warnings in this manual.
FLAMMABLE: This type of material contains flammable solvents such as xylene, toluene, naphtha, MEK, lacquer
thinner, acetone, denatured alcohol, and turpentine. The container label should indicate that this material is FLAM-
MABLE. This type of material is NOT compatible with your sprayer and CANNOT be used.
DO NOT RETURN THIS SPRAYER TO THE STORE!
