Operation
WARNING
Never exceed 20 psi (1.4 bar) static air pressure to
the cup. Exceeding the maximum working pressure
of the cup or any other system component could
cause component rupture, which could result in
serious injury and property damage.

WARNING
Pressure Relief Procedure
To reduce the risk of serious injury, including splash-
ing in the eyes or on the skin, always follow this
procedure after you stop spraying, when checking or
servicing any part of the spray system, before dis-
connecting the gun, air regulator, or pressure cup
and when removing a pressure cup for refilling or
cleaning.

Fig. 4
Spraying Tips
The regulator is not self relieving so if the regulated air
pressure setting is causing excessive fluid flow, follow
these steps.
1. Turn off the air supply to the gun.
2. Trigger the gun into a grounded metal waste
container to relieve fluid pressure.
3. Place the cup on a table and slowly release the
clamp (A) to bleed-off any residual pressure in
the cup. See Fig. 4. Be sure to push the clamp
lever fully to the clamped position before turning
on the air supply to the gun again.
1. Pull up the cup regulator adjustment knob lock-ring
(L). See Fig. 4.
2. Turn the adjustment knob (K) counterclockwise.
3. Trigger the gun into a grounded metal waste
container until cup pressure is lowered.
Setting the Cup Air Pressure
1. Pull up the cup regulator adjustment knob lock-ring
(L); this allows the knob (K) to turn. See Fig. 4.
4. Turn the adjustment knob (K) clockwise until you
obtain the desired lower pressure setting.
2. Set the cup pressure at zero by turning the
adjustment knob (K) fully counterclockwise.
5. Push down the adjustment knob lock-ring (L).
3. Slowly turn the adjustment knob (K) clockwise to
increase the air pressure to the cup.
CAUTION
Do not restrict the fluid flow by continuously spraying
with the gun’s fluid adjustment knob (M) turned in
(clockwise) as this will cause excessive abrasive
wear on the fluid needle and trigger/air valve shaft.
4. Push the adjustment knob lock-ring (L) down to
lock the cup pressure setting.
Setting the Gun Air Pressure
To restrict the fluid flow, lower the cup pressure or use
a smaller size needle/nozzle set and air cap combina-
tion.
NOTE: Installing the gun air inlet regulator adds a
pressure drop that could limit the air cap pressure.
Set the gun air pressure regulator for the minimum
pressure needed to atomize your fluid. See your gun
manual for recommended settings.
If the cup pressure must be below 1.0 psi (0.07 bar) to
achieve the desired fluid flow, a smaller needle/nozzle
size is recommended.

regulator adjustment knob (K) fully counterclock-
wise.

3. Turn on the air supply to the gun.
4. Turn the regulator adjustment knob (K) clockwise
to increase the air pressure to the gun.

WARNING
Never exceed 100 psi (7 bar) Maximum Working
Air Pressure to the gun. Exceeding the maxi-
mum working pressure of the gun or any other
system component could cause component
rupture, which could result in serious injury and
property damage.

Maintenance
5. If any fluid is in the lid elbow fitting (N), flush it with
Disconnect the Gun and Air Regulator
from the Cup
solvent but do not soak it in solvent for an
extended period.
1. Follow the Pressure Relief Procedure Warning
on page 4.
6. If fluid is in the tubing (3) or check valve (13),
replace them. See the parts list for your cup
assembly to order parts.
2. To disengage the tube grip, push down on the
outer ring of the lid elbow fitting (N), then pull the
tubing (3) out of the fitting. See Fig. 6.
3. Holding a wrench on the gun fluid inlet fitting,
disconnect the pressure cup swivel nut fitting (E).

CAUTION
Do not clean the air regulators in a gun washer as it
will damage the regulator diaphragm. Do not use any
cleaning method that allows solvent to enter the
regulator internally.
