distributor.
D Do not alter or modify this equipment. Use only genuine Graco parts and accessories.
D Check equipment daily. Repair or replace worn or damaged parts immediately.
D Do not exceed the maximum working pressure stated on the equipment or in the Technical Data
for your equipment. Do not exceed the maximum working pressure of the lowest rated component
in your system.
D Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the Tech-
nical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.
D Do not use hoses to pull equipment.
D Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose
Graco hoses to temperatures above 180_F (82_C) or below –40_F (–40_C).
D Comply with all applicable local, state, and national fire, electrical, and safety regulations.
D Never use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or
fluids containing such solvents in this equipment. Such use could result in a serious chemical
reaction, with the possibility of explosion, which could cause death, serious injury, and/or substan-
tial property damage.

WARNING
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury.
D Ground the equipment and the object being sprayed. Refer to Grounding on page 6.
D If there is any static sparking or you feel an electric shock while using this equipment, stop dis-
pensing immediately. Do not use the equipment until you identify and correct the problem.
D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being dispensed.
D Keep the dispense area free of debris, including solvent, rags, and gasoline.
D Extinguish all open flames or pilot lights in the dispense area.
D Do not smoke in the dispense area.
D Do not turn on or off any light switch in the dispense area while operating or if fumes are present.
D Do not operate a gasoline engine in the dispense area.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,
inhaled, or swallowed.
D Know the specific hazards of the fluid you are using.
D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.

Installation
NOTES:
D Fluid supply container: ground according to your
local code.
D Reference numbers and letters in parentheses in
the text refer to the callouts in the figures and
drawings.
D Flammable liquids in the spray area: must be in
approved, grounded containers. Do not store more
than the quantity needed for one shift.
D Accessories are available from your Graco
representative. If you supply your own accessories,
be sure they are adequately sized and
D 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
cardboard, which interrupts the grounding
continuity.
pressure-rated to meet the system’s requirements.
Grounding
WARNING
D To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the valve
firmly to the side of a grounded metal pail, then
trigger the valve.
FIRE AND EXPLOSION HAZARD
To reduce the risk of fire, explosion, and
serious injury, proper electrical ground-
ing of every part of your system is es-
sential. Read the warning section Fire
and Explosion Hazard on page 4, and
follow the grounding instructions below.
How to Use the Valve Trigger Safety
WARNING
SKIN INJECTION HAZARD
To prevent accidental triggering of the
gun and reduce the risk of a serious inju-
ry, including fluid injection or splashing in
the eyes or on the skin, lock the gun trigger safety
when you stop dispensing.
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.
1. If you are using one of the hand-held versions of
the valve, lock the valve trigger safety by turning
the latch to a right angle with the gun body. See
Fig. 2.
D Pump: ground the pump by connecting ground wire
and clamp as described in your separate pump
instruction manual.
2. To unlock the valve trigger safety, push the latch
out and turn it parallel with the gun body.
D Air compressors and hydraulic power supplies:
ground the equipment according to the
manufacturer’s recommendations.
D Fluid hoses: use only grounded fluid hoses with a
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 resistance,
contact the hose supplier or manufacturer for the
maximum electrical resistance limits, replace the
hose immediately.
