EQUIPMENT MISUSE HAZARD

General Safety

Misuse of the spray equipment or accessories, such as over

pressurizing, modifying parts, using incompatible chemicals

and fluids, or using worn or damaged parts, can cause them to

rupture and result in fluid injection, splashing in the eyes or the

skin, or other injury, or fire, explosion or property damage.
Never alter or modify any part of this equipment; doing so could

cause it to malfunction.
Check all spray equipment regularly and repair or replace worn

or damaged parts immediately.
Always wear protective eyewear, gloves, clothing and respira-

tor as recommended by the fluid and solvent manufacturer.

System Pressure

This sprayer can develop 3000 psi (210 bar) 

Maximum Working

Pressure. Be sure all spray equipment and accessories  used

are rated to withstand the this pressure. Do not exceed the

maximum working pressure of any component or accessory

used in the system.

Fluid and Solvent Compatibility

All chemicals used in the sprayer are chemically compatible

with the wetted parts shown in the 

Technical Data

 on the back

cover. Always read the chemical manufacturer’s literature be-

fore using them in this sprayer.

Hazard of Using Fluids Containing Halogenated

Hydrocarbons

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 chemical

reaction, with the possibility of explosion, which could cause

death, serious injury and/or substantial property damage.
Consult your fluid suppliers to ensure that the fluids being used

are compatible with aluminum and zinc parts.

FIRE OR EXPLOSION HAZARD

Static electricity is created by the flow of fluid through the pump

and hose. If every part of the spray equipment is not properly

grounded, sparking may occur , and the system may become

hazardous. Sparking may also occur when plugging in or un-

plugging a power supply cord or using a gasoline engine.

Sparks can ignite fumes from solvents and the fluid being

sprayed, dust particles and other flammable substances,

whether you are spraying indoors or outdoors, and can cause

a fire or explosion and serious injury and property damage.
If you experience any static sparking or even a slight shock

while using this equipment, 

stop spraying immediately

.

Check the entire system for proper grounding. Do not use the

system again until the problem has been identified and cor-

rected.

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. Be sure to ground all of this

spray equipment:
1. 

Sprayer:plug the power supply cord, or extension cord, each

equipped with an undamaged three-prong plug, into a prop-

erly grounded outlet. Do not use an adapter. All extensions

cords must have three wires and be rated for 15 amps.

2.

Fluid hoses: use only grounded hoses with a maximum

f

500 ft (150 m) combined hose length to ensure grounding

continuity. See 

Hose Grounding Continuity 

below.

3.

Spray gun: obtain grounding through connection to a prop-

erly grounded fluid hose and sprayer.

4.

Object being sprayed: according to local code.

5.

Fluid supply container: according to local code.

6.

All solvent pails used when flushing, 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.

7.

To maintain grounding continuity when flushing or relieving

pressure, always hold a metal part of the gun firmly to the side

of a grounded metal pail, then trigger the gun.

Flushing Safety

Reduce the risk of fluid injection injury

, static sparking, or

splashing by following the flushing procedure given on page 7

of this manual. Follow the 

Pressure Relief Procedure

 on page

2, and remove the spray tip before flushing. Hold a metal part

of the gun firmly to the side of a grounded metal pail and use the

lowest possible fluid pressure during flushing.

HOSE SAFETY

High pressure fluid in the hoses can be very dangerous. If the

hose develops a leak, split or rupture due to any kind of wear,

damage or misuse, the high pressure spray emitted from it can

cause a fluid injection injury or other serious injury or property

damage.

All fluid hoses must have strain reliefs on both ends!

 The

strain reliefs help protect the hose from kinks or bends at or

close to the coupling which can result in hose rupture.
Tighten all fluid connections securely before each use. High

pressure fluid can dislodge a loose coupling or allow high pres-

sure spray to be emitted from the coupling.
Never use a damaged hose. Before each use, check the entire

hose for cuts, leaks, abrasion, bulging cover , or damage or

movement of the hose couplings. If any of these conditions ex-

ist, replace the hose immediately. Do noT try to recouple high

pressure hose or mend it with tape or any other device. A re-

paired hose cannot contain the high pressure fluid.

Handle and route hoses carefully. Do not pull on hoses to move

equipment. Keep hoses clear of moving parts and hot surfaces

of the pump and gas engine. Do not use fluids or solvents which

are not compatible with the inner tube and cover of the hose. Do

not expose Graco hoses to temperatures above 180

 F (82

 C)

or below –40

 F (–40

 C).

Hose Grounding Continuity

Proper hose grounding continuity is essential to maintaining a

grounded spray system. 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 re-

sistance limits. Use a resistance meter in the appropriate range

for your hose to check the resistance. If the resistance exceeds

the recommended limits, replace it immediately

.  An  un-

grounded or poorly grounded hose can make your system haz-

ardous. Also read

United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards –

particularly the General Standards, Part 1910, and the Construction Standards, Part 1926 – should be consulted.
