Installation
General Information
WARNING
To reduce the risk of serious injury , always follow
the Pressure Relief Procedure on page 6 when -
ever you are instructed to relieve the pressure.
NOTE: Always use Genuine Graco Parts and Acces -
sories, available from your Graco distributor .
WARNING
Be sure your system has a bleed-type master air
valve and a fluid drain drain valve. These two
accessories help reduce the risk of serious bodily
injury , including fluid injection, splashing in the eyes
or on the skin, or injury from moving parts, if you
are adjusting or repairing the pump or gun.
 The bleed-type master air valve relieves air
trapped between this valve and the pump after
the air regulator is shut of f. T rapped air can
cause the pump to cycle unexpectedly .

The fluid drain valve Assists in relieving fluid
pressure in the displacement pump, hose, and
gun; triggering the gun to relieve pressure may
not be suf ficient.
1. Install the gasket (7) and then screw the swivel
body (1 1 or 13) firmly onto the gun. Don’t install
the spray tip yet. See Fig. 1.
2. Flush and then prime the pump or sprayer accord -
ing to the instructions supplied with it.
3. Relieve the Pressure.
4. Install an appropriate spray tip (A) in the tip
guard (12). Be sure the tip filter (9) is in place, and
then screw on the tip guard tightly . See Fig. 1.
CAUTION
Failure to install the tip filter (9) and the gasket (7)
will result in leaking at the nozzle.
5. Adjust the nozzle for the desired spray pattern
angle. Loosen the pivot screw (8) and move the
swivel nozzle (5) as needed. T ighten the pivot
screw . Refer to Fig. 2 for examples of dif ferent
angles.

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
T o reduce the risk of serious injury ,
including fluid injection, splashing in the
eyes or on the skin, or injury from mov -
ing parts or electric shock, always follow this proce -
dure whenever you:
 are instructed to relieve the pressure,
 stop spraying,
 check or service any of the system equipment,
 install or clean the spray tips,
 or shut off the pump.
1. Shut of f the pump and unplug it.
2. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun into the
paint pail to relieve pressure.
3. Engage the gun safety device.
4. Open your pump’ s or sprayer ’ s pressure relief
valve or drain valve.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
pressure gradually , then loosen completely . Now clear
the tip or hose.


Operation
WARNING
T o reduce the risk of a fluid injection injury , never
operate the gun with the tip guard(s) removed.
WARNING
T o reduce the risk of serious injury , always follow
the Pressure Relief Procedure on page 6 when -
ever you are instructed to relieve the pressure.
Whenever you stop spraying for a moment, engage
the gun safety latch.
Adjust the Spray Pattern
1. Relieve the Pressure.
2. T o adjust the spray pattern direction, engage the
safety knob and loosen the tip guard retaining nut.
T urn the spray tip so that the groove is horizontal
for a horizontal spray pattern, and vertical for a
vertical spray pattern.
3. The spray tip orifice size and spray angle deter -
mines the coverage and size of the pattern. When
more coverage is needed, use a larger spray tip
rather than increasing the fluid pressure.
4. If adjusting the pressure does not give a good
spray pattern, try another tip size. Be sure to
Relieve the Pressure completely before changing
tips.
CAUTION
Openings in the tip guard are designed to reduce
paint buildup on the guard while spraying. Any
damage to the sharp edges of the openings causes
paint to collect in that area. T o reduce the risk of
damage, never hang the gun by the tip guard.
Cleaning and Clearing the Spray Tip
WARNING
To reduce the risk of fluid injection or splashing in
the eyes or on the skin, do not hold your hand,
body , or a rag in front of the spray tip when clean -
ing or checking a clogged tip. Always point the gun
toward the ground or into a waste container when
checking to see if the spray tip is cleared.
Do not try to “blow back” paint; this is not an air
spray gun.
Do not wipe fluid buildup of f the gun or spray tip
until pressure is relieved. See the Pressure Relief
Procedure on page 6.
Clean of f the front of the tip frequently during the day’ s
operation and at the end of the work day . Remove and
clean the tip and filter (9) at least twice daily . See
Fig. 6. Always follow the Pressure Relief Procedure
on page 6. Use a solvent soaked brush to clean the
spray tip and to keep fluid buildup from drying and
clogging the spray tip.
If the spray tip clogs while spraying, release the spray
gun trigger , engage the trigger safety , shut of f the
pump and Relieve the Pressure. Remove the spray
tip and tip filter (9) and blow out the obstruction with air
from the front of the spray tip, or let the spray tip and
gun nozzle soak long enough to dissolve the obstruc -
tion. If the obstruction will not dissolve, jar it out by
tapping the back of the spray tip against a flat surface.
CAUTION
Never soak the entire gun in solvent. Prolonged
exposure to solvent can ruin the packings.
When not in use, keep the nozzles immersed in clean,
compatible solvent.

Maintenance
WARNING
T o reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
1. Relieve the Pressure
2. Disconnect the hose from the gun. Remove the tip
guards, tips and filters, and soak in a clean, com
-
patible solvent.
3. If the fluid leaks around the swivel, check the
tightness of the access plug (4). See Fig. 3.
4. If leakage continues, remove the nozzle adapter
from the gun. Unscrew the access plug (4). Re -
move the spring (1), washer (3), seal (6), and
