General Information
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
NOTE: Always use Genuine Graco Parts and Acces-
sories, available from your Graco distributor. If you
supply your own accessories, be sure they are ade-
quately sized and pressure rated for your system.
Fig. 2 is only a guide for selecting and installing sys-
tem components and accessories. Contact your Graco
distributor for assistance in designing a system to suit
your particular needs.
Prepare the Operator
All persons who operate the equipment must be
trained in the safe, efficient operation of all system
components as well as the proper handling of all fluids.
All operators must thoroughly read all instruction
manuals, tags, and labels before operating the equip-
ment.
Prepare the Site
The pump requires 12 scfm (0.336 m#/min) of com-
pressed air while operating at 120 psi (0.8 MPa, 8 bar)
air pressure and 60 cycles per minute. Ensure that you
have an adequate compressed air supply.
Refer to Fig. 2. Bring a compressed air supply line (A)
from the air compressor to the pump location. Be sure
all air hoses (A) are properly sized and pressure-rated
for your system. Use only electrically conductive
hoses. The air hose should have a 1/2 npt(m) thread.
Install a bleed-type shutoff valve (B) in the air line to
isolate the air line components for servicing. Install an
air line moisture trap and drain valve (C) to help re-
move moisture from the compressed air supply.
Keep the site clear of any obstacles or debris that
could interfere with the operator’s movement.
Have a grounded, metal pail available for use when
flushing the system or draining the fluid filter.
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
1. Pump: use the ground wire and clamp (supplied).

Supplied Components
Refer to Fig. 2.
WARNING
A red-handled bleed-type master air valve (1) and
a fluid drain valve (20) are supplied. These acces-
sories help reduce the risk of serious injury, includ-
ing fluid injection and splashing of fluid in the eyes
or on the skin, and injury from moving parts if you
are adjusting or repairing the pump.
The bleed-type master air valve relieves air trapped
between this valve and the pump after the valve is
closed. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient. Never connect a secondary hose or
spray gun to the fluid drain valve.
DThe red-handled bleed-type master air valve (1)
is required in your system to relieve air trapped
between it and the air motor when the valve is
closed (see the WARNING above). Be sure the
bleed valve is easily accessible from the pump, and
is located downstream from the air regulator (5).
DThe air regulator (5) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. It also removes harmful dirt and moisture
from the compressed air supply. Locate close to the
pump, but upstream from the bleed-type master air
valve (1).
DThe air manifold (27) provides ports for connect-
ing lines to air-powered accessories.
DThe fluid filter (10) includes a 60 mesh (250
micron) stainless steel element to filter particles
from the fluid as it leaves the pump.
DThe fluid drain valve (20) is required in your
system to relieve fluid pressure in the hose and gun
(see the WARNING above).
DThe agitator (59) is supplied on Model 226970
only. To prevent fluid from settling out, operate the
agitator as explained in its separate manual
306565.
Available Accessories (must be
purchased separately)
Refer to Fig. 2. Use necessary adapters when instal-
ling these accessories.
DThe air filter (D) removes harmful dirt and moisture
from the compressed air supply. Install upstream
from the air regulator (5).
DAn air line lubricator (F) provides automatic air
motor lubrication. Install downstream from all other
air line accessories.
Assemble the Sprayer
NOTE: Use thread sealant on all male threads except
at swivel connections.
1. Assemble the bushing (2), air regulator (5) and
attached parts to the red-handled bleed valve (1).
2. On Model 226970 only, connect the air hose
(59b) to the air inlet of the agitator (59a).
3. Screw the drain valve (20) into the open port of the
fluid filter (10). Screw the elbow (3) onto the drain
valve so the elbow points down.
WARNING
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient. Never connect a secondary hose or
spray gun to the fluid drain valve.
4. Connect the main fluid hose (6) to the nipple (30)
at the fluid filter (10) outlet.
5. On Model 226970 only, screw the gun swivel (58)
onto the other end of the hose (6).

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. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray tips.
1. Lock the gun trigger safety.
2. Close the red-handled bleed-type master air valve
(1, required in your system).
3. Close the air regulator (5).
4. Unlock the gun trigger safety.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
6. Lock the gun trigger safety.
7. Open the drain valve (20, required in your system),
having a container ready to catch the drainage.
8. Leave the 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, 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.
Packing Nut/Wet-Cup
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
The packing nut is torqued at the factory and is ready
for operation. If it becomes loose and there is leaking
from the throat packings, relieve pressure, then
torque the packing nut to 18 to 20 ft-lb (24 to 27 N.m).
Do this whenever necessary. Do not overtighten the
packing nut.
Flush the Pump Before First Use
The pump is tested with lightweight oil, which is left in
to protect the pump parts. If the fluid you are using
may be contaminated by the oil, flush it out with a
compatible solvent. See Flushing on page 10.
Using the Airless Spray Gun
Before operating the equipment, read the instruction
manual supplied with the gun.
Spray some test patterns before doing any finished
work. Refer to the gun manual for detailed information
on correct spraying technique.
Using the Agitator (Model 226970 only)
Before operating the agitator, read the agitator instruc-
tion manual supplied.

7. Hold a metal part of the gun (9) firmly to the side of
a grounded metal pail and hold the trigger open.
8. Slowly open the air regulator (5) until the pump
starts, about 40 psi (2.8 bar).
9. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed.
10. Release the gun trigger and lock the trigger safety.
The pump should stall against pressure.
Set the Air and Fluid Pressure
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
1. Relieve the pressure. Install the tip guard and
spray tip (31) in the gun (9), as explained in the
gun manual.
2. Open the air regulator (5) slowly. Use the regulator
to control pump speed and fluid pressure. Always
use the lowest air pressure necessary to get the
desired results. Higher pressures cause premature
tip and pump wear.
NOTE: To open the air regulator, turn the T-handle in
(clockwise). To close the regulator, turn the handle
counterclockwise. To lock the regulator setting, tighten
the jam nut.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause compo-
nent rupture and serious injury, never
exceed the specified Maximum Incoming Air Pres-
sure to the pump (see the Technical Data, on
page 16).
3. With the pump and lines primed, and with ade-
quate air pressure and volume supplied, the pump
will start and stop as you open and close the gun.
CAUTION
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the con-
tainer and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.

10 307621
Operation
Shutdown and Care of the Pump
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
For overnight shutdown, stop the pump at the bottom
of its stroke to prevent fluid from drying on the ex-
posed displacement rod and damaging the throat
packings. Relieve the pressure.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing below.

Graco Standard Warranty
Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the
date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty published by Graco,
Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be
defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or sub-
stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose in connection
with accessories, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured
by Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide
purchaser with reasonable assistance in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract,
breach of warranty, the negligence of Graco, or otherwise.
