MOVING PARTS HAZARD

Moving parts can pinch or amputate your fingers or other

body parts. KEEP CLEAR of moving parts when starting or

operating the sprayer.  Follow the

 Pressure Relief Proce-

dure 

on page 3 before checking or servicing any part of the

sprayer, to prevent it from starting accidentally.

EQUIPMENT MISUSE HAZARD

General Safety

Any misuse of the spray equipment or accessories, such as

overpressurizing, modifying parts, using incompatible chemi-

cals and fluids, or using worn or damaged parts, can cause

them to rupture and result in fluid injection, splashing in the

eyes or on the skin, or other serious bodily injury, or fire, ex-

plosion 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 respi-

rator as recommended by the fluid and solvent manufacturer.

System Pressure

This sprayer can develop 

195 bar (2750 psi) 

maximum

working pressure

.

 Be sure that all spray equipment and ac-

cessories used are rated to withstand this pressure. DO NOT

exceed the maximum working pressure of any component or

accessory used in the system.

Fluid and Solvent Compatibility

BE SURE that all fluids and solvents used are chemically

compatible with the wetted parts shown in the 

TECHNICAL

DATA

 on page 39. Always read the fluid and solvent manu-

facturer’s literature before using them in this sprayer.
Do not use 1,1,1-trichloroethane, methylene chloride, other

halogenated hydrocarbon solvents or fluids containing such

solvents in this equipment, which contains aluminum and/or

zinc parts. Such use could result in a serious chemical reac-

tion, with the possibility of explosion, which could cause death,

serious bodily injury and/or substantial property damage.

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 bodily injury

or property damage.

All fluid hoses must have spring guards on both ends!

Spring guards 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 pressure 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

exist, replace the hose immediately. DO NOT try to recouple

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

repaired 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 hose to tempera-
tures 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 resis-

tance, contact the hose supplier or manufacturer for the maxi-

mum resistance limits. Use a resistance meter in the appro-

priate range for your hose to check the resistance. If the

resistance exceeds the recommended limits, replace it imme-

diately. An ungrounded or poorly grounded hose can make

your system hazardous. Also read 

FIRE OR EXPLOSION

HAZARD.

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 unplugging a power supply cord. Sparks can ignite

fumes from solvents and the fluid being sprayed, dust parti-

cles and other flammable substances, whether you are

spraying indoors or outdoors, and can cause a fire or explo-

sion and serious bodily injury and property damage. Plug the

sprayer into a grounded outlet at least 20 ft. (6 m) from the

sprayer.
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 in-

structions for your area and type of equipment. BE SURE to

ground all of this spray equipment:
1.

Sprayer: plug into a properly grounded outlet. Do not use

an adapter. Extension cords must have three wires and

be rated for at least 15 amps.

2.

Fluid hoses: use only grounded hoses with a maximum of

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

continuity. See 

Hose Grounding Continuity

.

3.

Spray gun: obtain grounding through connection to a

properly 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 pa-

per or cardboard, which interrupts the grounding continu-

ity.

7.

To maintain grounding continuity when flushing or reliev-

ing 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

15 of this manual. Follow the 

Pressure Relief Procedure

 on

page 3, 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.

IMPORTANT

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.
