if you experience any static sparking or feel even a slight shock
while using thls equipment. STOP SPRAYiNG IMMEDIATELY. Check for proper grounding of the entire system. Do
not use the system again until the cause of the problem is identllied and corrected.
Grounding
To reduce the risk of statlc sparking. ground the pump and all
other equipment used or located in the spray area. CHECK your
local electrical code for detailed grounding instructions for your
area and type of equipment and be sure Jo ground all of the
following equipment:
1. Pump: use a ground wire and clamp as instructed in your
separate pump instruction manual.
2. AIr, fluid, and hydraulic hoses connected to the pump: use
only grounded hoses with a maximum of 500 feet 1150 m j
combined hose length to ensure grounding continuity. Refer
also to Hose Grounding Continuity. below.
High pressure fluid in the hoses can be very dangerous. if the
hose develops a leak. split or rupture due to any kind of wear.

are not compatible with the inner tube and cover of the hose. DO
NOT expose Graco hose to temperatures above 180- F (82' C)
or below -40' F 1-40' C l .
Hose Grounding Continuity
Proper hose grounding continuity is essential to malntaining a
grounded spray system. Check the electrical resistance of your
air and fluid hoses at least once a week. If your hose does not
have a tag on it which specifies the maximum electrical resistance. contact the hose supplier or manufacturer for the maximum resistance iimlts. Use a resistance meter in the appropriate range for your hose to check the resistance. If the reslstance exceeds the recommended limits. replace it immediately.
An ungrounded or poorly grounded hose can make your system
hazardous. Ais0 read FIRE OR EXPLOSION HAZARD,

Required Accessories
WARNING
Two accessories, the bleed-type master air valve
(C). and the fluid drain valve (E) are required for
your system to reduce the risk of serious bodily
injury from moving parts, splashing, or fluid injection when shutting off the pump.
The bleed-type master air valve (located downstream of the pump air regulator) relieves air
trapped between the valve and the pump, after
the pump is shut off. Trapped air can cause the
pump to cycle unexpectedly and result in serious
bodily injury if you are adjusting or repairing
the pump.
The Nuid drain valvefs) helps relieve fluid pressure in the displacement pump. hose and gun
when shutting off the pump. Triggering the gun to
relieve pressure may not be sufficient. especially
if there is a clog in the hose, gun. or tip.

Connect the Air Line
Install an air line filter (A) to ensure a clean. dry air
supply to the gun. Dirt and moisture in the line can ruin
the appearance of your finished piece.
Install fluid drain valve(s) (E) to help relieve fluid
Dressure.
Install an air pressure regulator (L) to control the air
pressure to the gun.
NOTE: The gun fluid connector (W) has a 1/4-16
npsm (R114-19) compound male thread that
is compatible with NPSM and ESP female
connectors.
Install a bleed-type master air valve (C) which is easily
accessible from the pump and.downstream from the
pump air regulator (D) , and one that is easily accessible from the gun and downstream from the gun air
reguiator (L).
Install an in-line fluid filter (N) (see part no. 210-500 in
the ACCESSORIES Section) on the gun fluid connector
(W) to avoid clogging the spray tip with particles from
your fluid.
NOTE: The gun air inlet has a 1/4-18 npsm (R1/4-19)
compound male thread that is compatible with
NPSM and BSP female swivel connectors.
Connect the grounded fluid hose (H)to the gun fluid
connector (W) or optional in-line filter (N).

WARNING
To reduce the risk of serious bodily injury, be sure
your entire system is properly grounded. Read
FIRE and EXPLOSION HAZARD on page 3. The
gun is grounded by connecting it to a properly
grounded pump and hose.
How the Air-Assisted Airless
Spray Gun Operates
The air-assisted airless gun combines airless and air
spraying concepts. The spray tip shapes the fluid into
a fan pattern, similar to a conventional airless spray
tip, but at a lower pressure. Air from the air cap further
atomizes the fluid and completes the atomization of
the paint tails into the pattern. The pattern adjustment
valve controls the width of the pattern.
Note that the air-assisted airless spray gun differs
from an air spray gun in that increasing the pattern air
reduces the pattern width. To increase the pattern
width, less pattern air or a larger size tip must be used.
The spray gun has a built-in lead and lag operation.
When triggered, the gun begins emitting air before the
fluid is discharged. When the trigger is released, the
fluid stops before the air flow stops. This helps assure
the spray is atomized and prevents fluid buildup on the
air cap.

on page 2 and 3 and throughout the text of this
instruction manual.

Select a Spray Tip and Air Cap
Vertical Spray Pattern
Horizontal Spray Pattern
Use the Spray Tip and Air Cap Selection Chart on
page 15, as a guide for selecting an appropriate spray
tip and air cap for your application. The fluid output
and pattern width depend on the size of the spray tip,
the fluid viscosity. and the fluid pressure.
If you are applying a solid stream of fluid. such as mastics or,sealants. refer to the Solid Stream Spray Tip
Selection Chart on page 15.
Fig 2
Use the information in the Air Cap Selection Chart to
help you choose either a Standard (provided with the
gun), Fine Finish, High Solids, or Solid Stream Air Cap,
depending on your application.
NOTE: When spraying at fluid pressures below 500 psi
(35 bar) or spraying light viscosity fluids, use
optional fluid needle 220-413 (see page 13).
The standard needle may not provide positive
shut off at those pressures or for such fluids.
When spraying acid catalyzed varnishes, use
optional fluid needle 222-497 (see page 13).
Using a standard needle may decrease needle
life and leakage may occur.

applications. See page 13.
1.
Set the fluid pressure at 300 psi (21 bar).
2. Trigger the gun to check the atomization: don't be
concerned about the pattern shape yet.
3. Increase the fluid pressure just to the point where
a further increase in fluid pressure does not significantly improve fluid atomization. DO NOT exceed
950 psi (66 bar) fluid pressure to the gun.
4.
RIGHT
Close the pattern adjustment valve by turning the
knob (see Fig 3) counterclockwise all the way.
(This sets the gun for its widest pattern.)
NOTE: lf you ara using the Fine Finish Air Cap, part
no. 219-093, the pattern adjustment valve
must be open (turned fully clockwise) when
operating the gun.
5. Set the atomizing air pressure at about 20 psi (1.4
bar). Check the spray pattern, then adjust the air
pressure until all the tails are completely atomized
and pulled into the spray pattern. See Fig 4. DO
NOT exceed 100 psi (7 bar) air pressure to the
gun.
For a narrowerpattern, turn the pattern adjustment
valve knob clockwise. If the pattern is still not narrow enough, increase the air pressure to the gun
slightly or use a different size tip.
NOTE: For some spray tips, when the line air pressure
to the gun is increased to a certain level, the
spray pattern will become round. This is the
smallest pattern width. Further increases in air
pressure will force the pattern to turn from
horizontal to vertical or from vertical to
horizontal.
