Installation
System Requirements
WARNING
The equipment must have a bleed-type master air
valve (pneumatic pumps only) and a pressure drain
valve. These accessories help reduce the risk of
serious injury from fluid injection, splashing in the
eyes or on the skin, or moving parts, when
adjusting or repairing the pump or gun.
1. The bleed-type master air valve relieves air
trapped between this valve and the pneumatic
pump after the air regulator is shut of f. T rapped air
can cause the pump to cycle unexpectedly .
2. The pressure drain valve assists in relieving fluid
pressure in the displacement pump, hose and gun;
triggering the gun to relieve pressure may not be
sufficient.
3.
Strain the fluid you are spraying if it contains
particles which could clog the spray tip.
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
T o reduce the risk of static sparking,
ground the pump and all other equipment
used or located in the spray area. Also
read FIRE OR EXPLOSION HAZARD on
page 2.
1. Check your local electrical code for detailed
grounding instructions for your area and type of
equipment.
2.
Follow the grounding instructions provided in your
pump or sprayer manual. The gun obtains ground -
ing through connection to a properly grounded fluid
hose and pump or sprayer .
Installation
1. Connect a grounded fluid hose to the gun inlet.
2. With no tip installed, start the pump/sprayer . Flush
it according to the instructions supplied with it.
Prime the system with the fluid you are using.

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally . Fluid
under high pressure can be injected through the
skin and cause serious injury . T o reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
 are instructed to relieve the pressure,
 stop spraying,
 check or service any of the system equipment,
 or install or clean the spray tip.
1. Engage the gun safety latch.
2. T urn the ON/OFF switch to OFF .
3. Unplug the power supply cord.
4. Disengage the gun safety latch. Hold a metal part
of the gun firmly to a grounded metal pail. T rigger
the gun to relieve pressure.
5. Engage the gun safety latch.
6. Open the pressure drain valve. Leave the pressure
drain valve open until you are ready to spray
again.
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 , VER Y SLOWL Y loos -
en the tip guard retaining nut or hose end coupling to
relieve pressure gradually , then loosen completely .
Now clear the tip or hose obstruction.
WARNING
INJECTION HAZARD
T o reduce the risk of serious injury ,
whenever you are instructed to relieve
pressure, follow the Pressure Relief
Procedure on page 6.
WARNING
The wallet-sized warning card provided with this gun
should be kept with the operator at all times. The card
contains important treatment information should an
injection injury occur. Additional cards are available
at no charge from Graco Inc.
1. Start the pump. Adjust the fluid pressure so the
spray is completely atomized. Always use the low -
est pressure necessary to get the desired results.
Higher pressure may not improve the spray pattern
and will cause premature tip and pump wear .
2.
If adjusting the pressure does not give a good
spray pattern, try another tip size. Be sure to re -
lieve pressure completely before changing tips.
3. Use a full open, full close trigger action. Hold the
gun about 14 in. (350 mm) from and at right angles
to the work surface. Don’t swing the gun in an arc.
Practice to find the best length and speed of
stroke.

Operation
Adjust the Spray Pattern
WARNING
INJECTION HAZARD
T o reduce the risk of serious injury ,
whenever you are instructed to relieve
pressure, follow the Pressure Relief
Procedure on page 6.
1. Relieve pressure.
2. T o adjust the spray pattern direction, engage the
safety latch. Loosen the tip guard retaining nut.
T urn the spray tip so the groove is horizontal for a
horizontal spray pattern and vertical for a vertical
pattern. T ighten the nut.
3. The spray tip orifice size and spray angle deter -
mines the coverage and size of pattern. When
more coverage is needed, use a larger spray tip
rather than increasing fluid pressure.
WARNING
To reduce the risk of a fluid injection injury, NEVER
use the gun with the tip guard or trigger guard
removed
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 at that area. T o reduce the risk of
damage, never hang the gun by the tip guard.
Cleaning and Clearing the Spray T ip
WARNING
To reduce the risk of serious injury from fluid injection
or splashing, always follow the Pressure Relief Pro -
cedure on page 6 before cleaning and clearing the
spray
tip.
Clean off the front of the tip frequently during the day’s
operation
and at the end of the work day . Then use a sol -
vent
soaked brush to clean the spray tip and to keep fluid
buildup from drying in and clogging the spray tip.
If the spray tip clogs while spraying, release the spray
gun trigger, engage the safety latch, shut off the pump,
and follow the Pressure Relief Procedure on page 2.
Then remove the spray tip 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 won’t dissolve, jar it out by tapping
the back of the spray tip against a flat surface.
When changing spray tips, take a moment to check the
tightness of the valve seat (21). It should be torqued to
190–210
in–lb (23–24 N.m). See Fig 3.
CAUTION
NEVER soak the entire gun in solvent. Prolonged
exposure to solvent can ruin the packings.
Flushing the Gun
WARNING
Before flushing , be sure the entire system and flush -
ing
pails are properly grounded. Refer to Grounding
on page 5. Follow the Pressure Relief Procedure
on page 6, and remove the spray tip from the gun.
Always use the lowest possible fluid pressure, and
maintain firm metal-to-metal contact between the
gun
and the pail during flushing to reduce the risk of
a fluid injection injury , static sparking and splashing.
See Fig 3.
Relieve pressure. Remove the spray tip. Flush the gun
and spray system with a compatible solvent. Always
flush
the gun before the fluid being sprayed can dry in it.
