Test spray pattern and atomization while holding
gun about 6-8 inches (150-200 mm) from test
piece.
a.
If pattern is too wide, turn pattern adjustment
knob (7) right to narrow pattern.
b.
To create a round pattern, turn pattern adjust-
ment knob (7) fully right.
c.
If pattern is too narrow, turn knob (7) left.

Check atomization. Increase gun air supply
pressure in 5 psi (34 kPa, 0.3 bar) increments
until you have the desired atomization.

Do not exceed maximum working air pressure shown
on front cover. Read warnings, page 2.

WARNING
Follow Pressure Relief Procedure when you stop
spraying and before cleaning, checking, or servicing

lubricant, dries out packings, and may clog air pas-
sages. You can immerse front end of gun in solvent
just until cup connection is covered.
• Do not use metal tools to clean air cap holes as this
may scratch them and distort the spray pattern.
• Use a compatible solvent.
