Spraying with Model 289233
• The cup lid has a check valve (113) that
prevents the cup from losing pressure
until the relief valve (112) is opened.
• To achieve the desired cup pressure,
start at a lower pressure and adjust up
to the desired setting. Normal operating
cup pressure is 3 to 6 psi (21 kPa,
0.2 bar) for most paints. Cup pressure
of 10 psi (69 kPa, 0.7 bar) or greater
may cause the cup to leak air or paint.
1. Fill cup (109) with material. Do not fill past
cup shoulder.
2. Screw cup onto lid securely. Press lever
(103) fully clockwise to seal cup.
3. Ensure relief valve (112) is closed (turn
clockwise).
4. Turn on shop air to gun.
5. Slowly turn the air pressure regulator knob
(201) clockwise while pulling the gun
trigger (10) completely back to adjust the
atomization. When you have the desired
atomization, push in knob to lock setting.
It is normal for the gauge pressure reading
to be higher when the gun trigger is
released.
6. To decrease paint flow, pull out the regulator
knob (201) and turn it counterclockwise to
lower pressure. Open the relief valve (112)
on the cup lid to relieve cup pressure.
7. Close relief valve (112). Regulator gauge
(204) will show current cup pressure.
8. Adjust the pattern size and shape with the
air control valve (5). Turn knob clockwise to
reduce pattern size and counterclockwise
to increase it.
6
9. Fluid control valve (8) is factory set for
maximum needle/trigger travel and material
flow. To decrease needle/trigger travel
and decrease fluid flow, turn the knob
clockwise.
Volatile Organic Compounds
(VOC) Regulation
In certain states, spraying solvents that release
VOCs into the atmosphere when cleaning
a spray gun is prohibited. To comply with these
air quality laws, you must use a cleaning
method that prevents the escape of VOC
vapors into the atmosphere. See Compliant
Cleaning Methods, page 8.
Clean air line filters as directed by the
manufacturer.
Maintenance
• Frequently lubricate the gun moving
parts with a drop of non-silicone oil
(part no. 8255).
• Do not disassemble the spray gun if you
are having a spray pattern problem. See
Troubleshooting, page 10, for information
on how to correct the problem.
• Check for fluid leakage. Tighten fittings or
replace equipment as needed.
