maximum of 500 feet (150 m) combined hose
length to ensure grounding continuity. Check the
electrical resistance of your fluid hoses at least
once a week. If your hose does not have a tag on
it which specifies the maximum electrical resis-
tance, contact the hose supplier or manufacturer
for the maximum resistance limits. If the hose
resistance exceeds the recommended limits,
replace it immediately.
WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of a fire, explosion,
and serious injury, proper electrical
grounding of every part of your system is
essential. Read the warning section,
FIRE AND EXPLOSION HAZARD, on
page 3 and follow the grounding
instructions below.
4. Flo-gun: ground the gun by connecting it to a
properly grounded fluid hose and pump.
5. Fluid supply container: ground according to the
The following grounding instructions are minimum
requirements for a basic dispensing system. Your
system may include other equipment or objects which
must be grounded. Check your local electrical code for
detailed grounding instructions for your area and type
of equipment. Your system must be connected to a
true earth ground.
local code.
6. Flammable liquids in the spray area: must be
kept in approved, grounded containers. Do not
store more than the quantity needed for one shift.
7. All solvent pails used when flushing: ground
according to local code. Use only metal pails,
which are conductive. Do not place the pail on a
non-conductive surface, such as paper or card-
board, which interrupts the grounding continuity.
1. Pump: ground the pump by connecting a ground
wire and clamp as described in your separate
pump instruction manual.
8. To maintain grounding continuity when flush-
ing or relieving pressure: hold a metal part of
the gun firmly to the side of a grounded metal pail,
then trigger the gun.
2. Air compressors and hydraulic power
supplies: ground the equipment according to the
manufacturer’s recommendations.

Gun Trigger Safety
WARNING
WARNING
SKIN INJECTION HAZARD
To prevent accidental triggering of the
gun and reduce the risk of a serious
injury, including fluid injection or splash-
ing in the eyes or on skin, lock the gun trigger
safety when you stop dispensing.
SKIN 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 a serious injury. To reduce the risk
of an injury from injection, splashing fluid, or mov-
ing parts, follow the Pressure Relief Procedure
whenever you:
To lock the gun safety, release the trigger and rotate
the safety toward the trigger as shown in Fig. 1.
D are instructed to relieve the pressure,
D stop dispensing,
D check or service any of the system equipment,
D or install or clean the nozzle.
NOTE: Do not try to force the trigger valve open with
the safety engaged. This could result in component
failure.
1. Fully release the gun trigger and lock the gun
trigger safety by rotating the safety forward. See
Fig. 1.
2. Shut off the fluid supply pump.
3. Hold a metal part of the gun firmly to the side of a
grounded metal waste container. Unlock the gun
trigger safety by rotating the safety backward. See
Fig. 2. Trigger the gun to relieve fluid pressure.

4. Fully release the gun trigger and lock the gun
trigger safety by rotating the safety forward.
To unlock the trigger safety, rotate the safety toward
the handle as shown in Fig. 2.
5. Open the pump drain valve to help relieve fluid
pressure in the pump, hose, and gun. Triggering
the gun to relieve pressure may not be sufficient.
Have a container ready to catch the drainage.
6. Leave the drain valve open until you are ready to
dispense again.
7. If you think that the gun nozzle or fluid hose is
completely clogged or that pressure has not been
fully relieved after following the steps above, very
slowly loosen the hose end coupling and relieve
pressure gradually, then loosen the coupling
completely. Clear the nozzle or hose obstruction.

Operation
Dispensing
Flushing Safety
1. Start the fluid supply pump.
WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of a fire, explosion, or
serious injury,
2. The fluid flow rate is controlled at the pump. Adjust
the pump pressure to obtain the desired flow rate.
It is recommended that you use the lowest pres-
sure necessary to dispense the fluid. The pressure
adjustment will depend on the hose length, the
viscosity of the fluid, and the gun nozzle size.
D Be sure the entire system and flush-
ing pails are properly grounded
before flushing the gun or system.
Read Grounding the System, on page 5.
3. Unlock the gun trigger safety.
4. Squeeze the trigger in all the way. Fluid flow
begins with the slightest pressure on the trigger
and stops when the trigger is released.
D Use the lowest possible fluid pressure and
maintain firm metal-to-metal contact between
the gun and the grounded metal pail during
flushing.
NOTE: Periodically inspect the vent in the gun handle
for fluid buildup which could indicate an internal leak.
See Fig. 3. Service the fluid tube and o-ring as
needed.

WARNING
SKIN INJECTION HAZARD
To reduce the risk of a serious injury,
including fluid injection,
disassemble the gun as instructed on page 11.
Clean and inspect the parts. Replace any worn
or damaged parts and reassemble the gun as
instructed on page 11.
3. Follow the torque, sealant and lubrication notes for
your gun model number.
D Follow the Pressure Relief Procedure on page
6 when you stop dispensing, before servicing
the gun, and whenever you are instructed to
relieve the pressure.
4. The following repair kits are available:
D After adjusting or servicing the gun, make sure
the fluid will not trigger on when the trigger
safety is locked. If fluid does flow, the gun is not
assembled properly or the trigger safety is
damaged. Reassemble the gun or return it to
your nearest Graco distributor. Do not use the
gun until the problem is corrected.

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 accor-
dance 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.
