D check or service any of the system equipment,
D or install or clean the spray tip.
Starting and Adjusting the Pump
Begin these steps before you install the spray tip.
1. Lock the gun trigger safety.
1. Ensure that the air regulator (E) and bleed-type
master air valve (D) are closed. See Fig. 2 on
page 6.
2. Shut off the air supply to the pump.
3. Close the bleed-type master air valve (required in
your system).
2. Connect a suction hose (N) to the pump’s fluid
inlet, or lower the pump into a fluid supply
container.
4. Unlock the gun trigger safety.
3. Hold a metal part of the spray gun (M) firmly to the
side of a grounded metal pail and hold the trigger
open.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
4. Open the pump’s bleed-type master air valve (D).
6. Lock the gun trigger safety.
5. Slowly open the air regulator (E) until the pump
starts (approximately 40 psi [0.28 MPa, 2.8 bar]).
7. Open the drain valve (required in your system),
and have a container ready to catch the drainage.
6. Cycle the pump slowly until all the air is pushed
out and the pump and hoses are fully primed.
8. Leave the drain valve open until you are ready to
spray again.
7. Release the spray gun trigger and lock the trigger
safety. The pump should stall against pressure
when you release the trigger.
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 it completely. Then
clear the tip or hose.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
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 before using the pump. If the pump
is being used to supply a circulating system, allow the
solvent to circulate until the pump is thoroughly
flushed. See Flushing the Pump on page 9.

component rupture and serious injury,
never exceed the specified maximum air input
pressure to the pump (see Technical Data on
page 20).
10. Control the pump speed and fluid pressure with
the air regulator (E). Always use the lowest air
pressure necessary to get the desired results.
Higher pressure causes premature spray tip and
pump wear.
Flush with a fluid that is compatible with the fluid you
are pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for
recommended flushing fluids and flushing frequency.
Always flush the pump before fluid dries on the
displacement rod.
11. With the pump and lines primed, and with
adequate air pressure and volume supplied, the
pump starts and stops as the spray gun is opened
and closed. In a circulating system, the pump runs
continuously and speeds up or slows down as
supply increases or decreases until the air supply
is shut off.
CAUTION
Never leave water or water-base fluid in the pump
overnight. If you are pumping water-base fluid, flush
with water first, then with a rust inhibitor such as
mineral spirits. Relieve the pressure, but leave the
rust inhibitor in the pump to protect the parts from
corrosion.
CAUTION
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself. If your pump accel-
erates quickly, or is running too fast, stop it immedi-
ately and check the fluid supply. If the supply con-
tainer is empty and air has been pumped into the
lines, refill the container and prime the pump and the
lines with fluid, or flush and leave it filled with a
compatible solvent. Be sure to eliminate all air from
the fluid system.

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
substitution 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.
