variety of materials such as lacquers,

To use your spray gun:
1. Read and follow the material manufac-
turer's instructions for spraying, mixing,
safety, disposal, and any other instruc-
tion on the label or Material Safety Data
Sheet (MSDS).
2. Ensure the cup is securely tightened
and all other fittings are secure to avoid
air leaks or material spills.

ing to the spray gun) to the lowest
pressure recommended in Tool Data
Sheet on Page 8 or to the material
manufacturer's recommendations.

horizontal. See Atomizing Cap and
Fan Adjustments on Page 13 for fur-
ther explanation.

the results you want along with a fair
amount of practice. Test your material
flow and spray pattern on a piece of
cardboard or some scrap of material
similar to your project.
