WARNING

INJECTION HAZARD

Spray from the gun, hose leaks or ruptured components can inject fluid into your body and cause an
extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin
can also cause serious injury.

D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medi-

cal attention.

D Do not point the spray gun at anyone or any part of the body.

D Do not put hand or fingers over the spray tip.

D Do not stop or deflect fluid leaks with your hand, body, glove or rag.

D Do not “blow back” fluid; this is not an air spray system.

D Always have the tip guard and the trigger guard on the spray gun when spraying.

D Check the gun diffuser operation weekly.

D Be sure the gun trigger safety operates before spraying.

D Lock the gun trigger safety when you stop spraying.

D Follow the Pressure Relief Procedure on page 7 if the spray tip clogs and whenever you: are

instructed to relieve pressure; stop spraying; clean, check, or service the equipment; and install or
clean the spray tip.

D Tighten all fluid connections before operating the equipment.

D Check the hoses, tubes and couplings daily. Replace worn, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

TOXIC FLUID HAZARD

Hazardous fluids or toxic fumes can cause serious injury or death if splashed in the eyes or on the
skin, swallowed, or inhaled.

D Know the specific hazards of the fluid you are using. Read the fluid manufacturer’s warnings.

D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,

state and national guidelines.

D Wear the appropriate clothing, gloves, eyewear and respirator.

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor air ventilation, open flames or sparks can cause a hazardous condition and
result in fire or explosion and serious injury.

D Ground the equipment and the object being sprayed. See Ground the System on page 6.

D If there is any static sparking while using the equipment, stop spraying immediately. Identify and

correct the problem.

D Provide fresh air ventilation to avoid the buildup of flammable vapors from solvent or the fluid being

sprayed.

D Do not smoke in the spray area.

D Extinguish all open flames or pilot lights in the spray area.

D Do not turn on or off any light switch in the spray area while operating or if fumes are present.

D Electrically disconnect all equipment in the spray area.

D Keep the spray area free of debris, including solvent, rags, and gasoline.

D Do not operate a gasoline engine in the spray area.

EQUIPMENT MISUSE HAZARD

INSTRUCTIONS

Equipment misuse can cause the equipment to rupture, malfunction or start unexpectedly and result in
serious injury.

D This equipment is for professional use only.

D Read all instruction manuals, tags, and labels before operating the equipment.

D Use the equipment only for its intended purpose. If you are uncertain about usage, call your Graco

distributor.

D Do not alter or modify this equipment. Use only genuine Graco parts and accessories.

D Check the equipment daily. Repair or replace worn or damaged parts immediately.

D Do not exceed the maximum working pressure of the lowest rated system component. This equip-

ment has a 7400 psi (50.8 MPa, 510 bar) Maximum Working Pressure.

D Use fluids or solvents which are compatible with equipment wetted parts. See the Technical Data

section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.

D Route the hoses away from the 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 Use only Graco approved hoses. Do not remove hose spring guards, which help protect the hose

from rupture caused by kinks or bends near the couplings.

D Wear hearing protection when operating this equipment.

D Comply with all applicable local, state and national fire, electrical and other safety regulations.

RECOIL HAZARD

Due to the very high fluid pressure, a strong recoil action will 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.

System Requirements

WARNING

INJECTION HAZARD

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

The equipment must have a bleed-type master air
valve (pneumatic pumps only) and a fluid drain
valve. These accessories help reduce the risk of
serious injury from injection, splashing in the eyes
or on the skin, or moving parts, when adjusting or
repairing the pump or gun.

1. The bleed-type master air valve relieves air
trapped between this valve and the pneumatic
pump after the air regulator is shut off. Trapped air
can cause the pump to cycle unexpectedly.

Ground the System

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding could cause static
sparking, which could cause a fire or
explosion. To reduce the risk of property
damage or serious injury, ground the

pump and all other equipment used or
located in the spray area. Also read FIRE OR
EXPLOSION HAZARD on page 4.

Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Also
follow the grounding instructions provided in your
pump or sprayer manual. The gun obtains grounding
through connection to a properly grounded fluid hose
and pump or sprayer.

How to Use the Gun Trigger Safety

1. To lock the gun trigger safety, turn the safety to a
right angle with the gun body. See Fig. 1.

2. To unlock the gun trigger safety, push the safety
out and turn it parallel with the gun body. See
Fig. 1.

2. The fluid drain valve assists in relieving fluid pres­sure in the displacement pump, hose and gun;
triggering the gun to relieve pressure may not be
sufficient.
