Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: use a ground wire and clamp. Remove the green
ground screw (Z) from the bottom of the air motor. Insert
the screw through the loop on the end of the ground wire
(Y) and reattach the screw to the air motor. Connect the
ground clamp to a true earth ground. See F
IG. 1.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
Pressure Relief Procedure
1. Engage trigger lock.
2. Air-Powered Pumps only: Close the bleed-type
master air valve.
Z Y
TI8250a
FIG. 1
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check the
electrical resistance of hoses. If total resistance to
ground exceeds 29 megohms, replace hose immediately.
Air compressor: follow manufacturer’s recommendations.
Hydraulic power supply: follow manufacturer’s recommendations.
Surge tank: use a ground wire and clamp.
Spray gun: ground through a connection to a properly
grounded fluid hose and pump.
Hydraulic-Powered Pumps only: Close the hydraulic
supply line valve first, then the return line valve.
3. Disengage the trigger lock.
4. Hold a metal part of the gun firmly to a grounded
metal pail. Trigger the gun to relieve pressure.
5. Engage the trigger lock.
6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to spray
again.
7. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen tip
guard retaining nut or hose end coupling to relieve
6 311832D
pressure gradually, then loosen completely. Clear
hose or tip obstruction.
CAUTION
Hydraulic-Powered Pumps only: When shutting down
the hydraulic system, always shut off the hydraulic
supply line shutoff valve first, and then the return line
shutoff valve to prevent overpressurizing the motor or
its seals. When starting the hydraulic system, open
the return line shutoff valve first.
Repair
CAUTION
Be careful not to drop or damage the balls (13) or
seats (17). A damaged ball or seat cannot seal properly and the pump will leak. The outlet valve seats
(17) can be reversed to provide longer use of the seat.

Graco Standard Warranty
Graco warrants all equipment referenced in this document which is 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.

PARTICULAR PURPOSE, IN CONNECTION WITH ACCESSORIES, EQUIPMENT, MATERIALS OR COMPONENTS SOLD BUT NOT

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.
