Caution Symbol
CAUTION
This symbol alerts you to the possibility of damage to
or destruction of equipment if you do not follow the
instructions.
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury.
If there is any static sparking or you feel an electric shock while using this equipment, stop
spraying immediately. Do not use the equipment until you identify and correct the problem.
Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being sprayed.
Keep the spray area free of debris, including solvent, rags, and gasoline.
Electrically disconnect all equipment in the spray area.
Extinguish all open flames or pilot lights in the spray area.
Do not smoke in the spray area.
Do not turn on or off any light switch in the spray area while operating or if fumes are present.
Do not operate a gasoline engine in the spray area.
Ground the equipment and the object being sprayed. See Grounding on page 5.

WARNINGWARNING
INJECTION HAZARD
Spray from the gun, leaks or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin
can also cause serious injury.
Fluid injected into the skin is a serious injury. The injury may look like just a cut, but it is a serious
injury. Get immediate medical attention.
Do not point the gun at anyone or at any part of the body.
Do not put your hand or fingers over the spray tip.
Do not stop or deflect leaks with your hand, body, glove or rag.
Do not “blow back” fluid; this is not an air spray system.
Always have the tip guard and the trigger guard on the gun when spraying.
Check the gun diffuser operation weekly. Refer to the gun manual.
Be sure the gun trigger safety operates before spraying.
Lock the gun trigger safety when you stop spraying.
Follow the Pressure Relief Procedure on page 5 if the spray tip clogs and before cleaning,
checking or servicing the equipment.
Tighten all fluid connections before operating the equipment.
Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. Do
not repair high pressure couplings; you must replace the entire hose.
Fluid hoses must have spring guards on both ends, to help protect them from rupture caused by
kinks or bends near the couplings.
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.
Know the specific hazards of the fluid you are using.
Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid
and solvent manufacturer.
RECOIL HAZARD
Due to the high pressure fluid emitted, a strong recoil action may occur when you trigger this gun. If
you are unprepared, your hand could be forced back toward your body or you could lose your balance and fall, resulting in serious injury.

Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s
warnings.
Do not use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or
fluids containing such solvents in pressurized aluminum equipment. Such use could result in a
chemical reaction, with the possibility of explosion.

Installation/Operation
WARNING
WARNING
Keep the wallet-sized warning card provided with
this gun with the operator at all times. The card
contains important treatment information should an
injection injury occur. Additional cards are available
at no charge from Graco Inc.
WARNING
Be sure your system has a bleed-type master air
valve (pneumatic pumps only) and a pressure drain
valve. These accessories help reduce the risk of
serious bodily injury, including fluid injection,
splashing in the eyes or on the skin, or injury from
moving parts, if you are adjusting or repairing the
pump or gun.
1. The bleed-type master air valve (air-powered
pumps only) relieves air trapped between this
valve and the pump after the air regulator is shut
off. Trapped air can cause the pump to cycle
unexpectedly.
2. The pressure drain valve assists in relieving fluid
pressure in the displacement pump, hose and gun:
triggering the gun to relieve pressure may not be
sufficient.
3. Strain the fluid you are spraying if it contains
particles which could clog the spray tip.
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:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray tip.
Pressure Relief Procedure
1. Engage the gun safety latch.
2. Turn the ON/OFF switch to OFF.
3. Unplug the power supply cord.
4. Disengage the gun safety latch. Hold a metal part
of the gun firmly to a grounded metal pail. Trigger
the gun to relieve pressure.
5. Engage the gun safety latch.
6. Open the system pressure drain valve. Leave the
pressure 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 loos-
en the tip guard retaining nut or hose end coupling to
relieve pressure gradually, then loosen completely.
Now clear the tip or hose obstruction.
Grounding
To reduce the risk of static sparking, ground the sprayer and all other spray equipment used or located in the
spray area. Check your local electrical code for detailed grounding instructions for your area and type of
equipment.
How to Use the Gun Trigger Safety
1. To engage the gun trigger safety, turn the latch to
a right angle with the gun body. See Fig. 1.
2. To disengage the gun trigger safety, push the latch
out and turn it parallel with the gun body.
