WARNING

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 4 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.

MOVING PARTS HAZARD

Moving parts can pinch or amputate your fingers.

Keep clear of all moving parts when starting or operating the pump.

Before servicing the equipment, follow the Pressure Relief Procedure on page 4 to prevent the

equipment from starting unexpectedly.

WARNING

INSTRUCTIONS

EQUIPMENT MISUSE HAZARD

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

This equipment is for professional use only.

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

Use the equipment only for its intended purpose. If you are not sure, call your distributor.

Do not alter or modify this equipment. Use only genuine Graco parts.

Check equipment daily. Repair or replace worn or damaged parts immediately.

Do not exceed the maximum working pressure of the lowest rated system component. Refer to the

Technical Data on page 9 for the maximum working pressure of this equipment.

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.

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.

Do not use hoses to pull equipment.

Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose

Graco hoses to temperatures above 82C (180F) or below –40C (–40F).

Do not lift pressurized equipment.

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

Wear ear protection when operating this equipment.

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.

If there is any static sparking or you feel an electric shock while using this equipment, stop spray-

ing 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.

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually

relieved to prevent the system from

starting or spraying accidentally. To

reduce the risk of an injury from accidental spray

from the gun, 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 nozzle.

1. Engage gun safety latch.

2. Turn ON/OFF switch to OFF.

3. Unplug power cord.

4. Disengage gun safety latch. Hold metal part of gun

against grounded metal pail and trigger gun into

pail to relieve pressure.

5. Engage gun safety latch.

6. Open any fluid drain valves in system. Leave drain

valve open until ready to dispense again.

Cleaning and Inspecting Parts

Clean and inspect parts. Pay particular attention to the

ball seats in the intake valve and piston, which must

have no nicks or wear, and to the inside of the cylinder

and the outside of the piston rod, which must not be

worn or scratched. Replace worn or damaged parts.

WARNING

COMPONENT RUPTURE HAZARD

Do not clean or wipe the piston valve

threads. Cleaning the piston valve

threads could destroy the plastic patch

and cause the piston valve to come loose during

operation, causing pump bursting and possible

serious bodily injury.

Fig. 7. Unscrew piston valve from piston rod. Clean

and inspect parts. The piston has a plastic sealing

patch. Do not remove the patch. The patch allows four

disassembly/assembly procedures before it is

necessary to apply Loctiteto the threads.

and leather (218) packings (note orientation) on piston

rod. Install female gland (217). Install backup washer

(216) and u-cup (209) (note orientation) on piston

valve (210). The special sealing patch on piston valve

threads is good for four repackings. Use Loctiteon

piston valve threads after four repackings.
