F . 3. For maximum fluid flow and to prevent premature
IG
fluid nozzle wear, turn fluid adjustment knob (20) left until
no trigger restriction is felt; trigger should be able to touch
gun handle. Then turn knob out 1/2 turn more.
3.
If further fluid flow restriction is needed, use different size
needle/nozzle/air cap combination.
If necessary, fluid adjustment knob (20) can be turned right
to reduce volume of fluid output. However, continuously
spraying with fluid adjustment knob closed causes accele-
rated abrasive wear on fluid needle and trigger/air valve
shaft interface.
If fluid adjustment knob (20) is turned in all the way, the
gun emits only air.
4.
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 adjustment
knob (7) fully right.
c.
If pattern is too narrow, turn knob (7) left.
d.
Check atomization. Increase gun air supply pressure in
5 psi (34 kPa, 0.3 bar) increments until you have the
desired atomization.
WARNING
Do not exceed maximum working air pressure shown on
front cover. Read warnings, page 2.

movement and make fewer passes than you would with a

conventional air spray gun. Take care to avoid runs or sags.

Daily Cleaning and Maintenance
WARNING
Follow Pressure Relief Procedure when you stop spraying
and before cleaning, checking, or servicing equipment. Read
warnings, page 2.
• Do not submerge gun in solvent. Solvent dissolves lubri-
cant, dries out packings, and may clog air passages. 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.
1.
Follow Pressure Relief Procedure, page 1.
2.
Clean fluid and air line filters.
3.
Check for fluid leakage from gun and fluid hoses. Tighten
fittings or replace equipment as needed.
4.
Flush gun before changing colors and when you are done
spraying.
5.
Remove cup (30) and filter (29) and clean them. F
6.
Remove air cap (1) and nozzle (2) as instructed on page 5
and soak them in compatible solvent.
Trigger gun and use gun tool (27) whenever you tighten or
remove nozzle (2) to avoid damaging needle seat (4) and
nozzle,
7.
Use a rag moistened in solvent to wipe down outside of gun.
8.
Before reinstalling air cap and nozzle, clean
them and front of gun with a soft-bristle brush
dipped into compatible solvent. Do not use a
wire brush or metal tools. To clean out air cap
holes, use a soft implement, such as a tooth-
pick.
9.
Lubricate gun.
