operating

equipment.

FLUID INJECTlON HAZARD

G e n e r a l S a f e t y

Airless spray equipment generates very high fluid pressure.

Spray from the gun, leaks or ruptured components can inject fluid through your skin and into your body and cause extreme- ly serious bodily injury, including the need for amputatlon.

Also, fluid injected or splashed into the eyes can cause serious damage.

Spray Tip Safety

Use extreme caution when cleaning or changing spray tips. If the spray tip clogs while spraying, engage the gun safety latch immediately. ALWAYS follow the Pressure Relief Pro- cedure. below, and then remove the spray tip to clean it.

NEVER wipe off build-up around the spray tip until pressure is fully relieved and the gun safety latch is engaged.

NEVER point the spray gun at anyone or at any part of the body. NEVER put hand or fingers over the spray tip. NEVER try to "blow back" paint; this is NOT an air spray gun.

ALWAYS have the tip guard in place on the spray gun when spraying.

* .

Pressure Relief P r o c e d u r e

To reduce the risk of serious bodily injury, including injection; splashing in the eyes; or injury from moving parts, always follow this procedure whenever you shut off the spray equip- ment, when checking or servicing any part of the spray system, when installing, cleaning or changing spray tips. and whenever you stop spraying.

ALWAYS follow the Pressure Relief Procedure. below. before cleaning or removing the spray tip or servicing any system equipment.

NEVER try t o stop or deflect leaks with your hand or body.

Be sure equipment safety devices are operating properly

M e d i c a l A l e r t - A i r l e s s S p r a y Wounds

If any fluid appears to penetrate your skin. get EMERGENCY

MEDICAL CARE A T ONCE, DO NOT TREAT AS A

SIMPLE CUT. Tell the doctor exactlywhatfluid was injected.

Note to Physlclan: Injection in the skin is a traumatic in- jury. It Is lrnponent t o treat t h e injury surgically as soon e8 possible. Do not delay treatment to research toxicity.

Toxicity is a concern with some exotic coatings injected directly into the blood stream. Consultation with a plastic surgeon or reconstructive hand surgeon may be advisable.

1. Engage the gun safety latch.

2. Shut off the power supply t o the pump and close the bleed- type master air valve (required in the system).

3. Disengage the gun safety latch.

4. Hold a metal part of the gun firmly to the side of a ground- ed metal pail, and trigger the gun into the pail to relieve

"rL9911re~

5. Engage the gun safety latch.

6. Open the pump fluid drain valve (required in the system), having a container ready to catch the drainage.

7. Leave the drain valve open until you are ready t o spray again.

If you suspect that the spray tip or hose is completely dogged, or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip or hose.

S p r a y Gun Safety D e v i c e s

Be sure all gun safety devices are operating properly before each use. Do not remove or modify any part of the gun; this can cause a malfunction and result in serious bodily injury.

EQUIPMENT MISUSE HAZARD

l

Safety Latch

Whenever you stop spraying, even for a moment, always engage the gun safety latch in the closed or ON SAFE posi- tion, making the gun inoperative. Failure to engage the safety latch can result in accidental triggering of the gun. See Fig 1,

page 4.

G e n e r a l S a f e t y

Any misuse of the spray equipment or accessories, such as overpressurizing. modifying parts, using incompatible chemicals and fluids, or using worn or damaged parts, can cause them t o rupture and result in injection or other serious bodily injury, fire, explosion or propem damage.

NEVER alter or modify any part of this equipment; doing so could cause it to malfunction.

Diffuser

The gun diffuser breaks up spray and reduces the risk of injec- tion when the tip is not installed. Check diffuser operation regularly. Follow the Pressure Relief Procedure. below, then remove the spray tip. Aim the gun into a grounded metal pail, holding the gun firmly to the pail. Using the lowest possi- ble pressure, trigger the gun. If the fluid emitted is not diffused into an irregular stream, replace the diffuser immediately.

CHECK all spray equipment regularly and repair or replace worn or damaged parts immediately.

Read and follow the fluid solvent manufacturer's literature regarding the use of protective clothing and equipment.

Tip Guard

ALWAYS have the tip guard in place on the spray gun while spraying. The tip guard alerts you to the injection hazard and helps reduce, but does not prevent, accidentally placing your fingers or any part of your body close to the spray tip.

S stem P r e s s u r e

DE NOT exceed 36w 1252 bar1 MAXIMUM WORKING

PRESSURE to the gun. Be sure ail accessory items and system components are rated t o withstand the pressures developed. NEVER exceed the pressure rating of any compo- nent in the system.

Trigger Guard

NEVER operate the gun with the trigger guard removed. The trigger guard reduces the risk of accidentally triggering the gun if it is dropped or bumped.

Fluid C o m p a t i b i l i t y

BE SURE that all fluids and solvents used are chemically corn- patible with the w m e d parts shown in the Technical Data on the back cover. Always read the manufacturer's literature before using a fluid or solvent in the system.

FIRE OR EXPLOSION HAZARD

Static electricity is created by the high velocity flow of fluid through the pump and hose. If every part of the spray equip- ment 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-particles and other flammable substances, whether you are spraying indoors or outdoors, and can cause a fire or ex- plosion and serious bodily injury and property damage. Do not plug in or unplug any power supply cords in the spray area when there is any chance of igniting fumes still in the air.

If you experience any static sparking or even a slight shock while using this equipment, STOP SPRAYING IM-

MEDIATELY. Check the entire svstem for oositive oround- ing. Do not use the system again until the pioblem h i s been identified and corrected.

Grounding

To reduce the risk of static sparking, ground all the spray equipment used or located in the spray area. CHECK your local electrical code and your equipment's individual instruc- tion manuals for detailed oroundino instructions for vour area and type of equipment a d a l l of ihis spray equipment:

1. Pump or sprayer: as instructed in your separate pump or sprayer manual.

2. Air compressor or hydraulic power supply: according to local code.

3. Fluid hoses: use only grounded hoses with a maximum of

5M) feet (150 m) combined hose length t o ensure ground- ing continuity. Refer to Hose Grounding Continuity.

4. Spray gun: obtain grounding through connection to a properly grounded fluid hose and sprayer or pump.

5. Fluid supply container: according t o local code.

6. Object being sprayed: according to local code.

7. A l l solvent pails used when flushing, according to local code. Use only metalpails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity.

8. To maintain grounding continuity when flushing or reliev- ingpressure, always hold a metal part of the gun firmly to the side of a metal pail, then trigger the gun.

Flushing S a f e t y

Before flushing, be sure the entire system and flushing pails are properly grounded. Refer to Grounding, above. Follow the Pressure Relief Procedure on page 2, and remove the spray tip from the gun. Always use the lowest possible fluid pressure. and maintain firm methl-to-metal contact between the gun and a grounded metal pail during flushing to reduce the risk of injection injury, static sparking and splashing.

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 an injection injury or other serious bodily injury or pro- perly damage.

ALL FLUID HOSES MUST HAVE SPRING GUARDS O N

BOTH ENDS1 The 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 en- tire 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 t o recouple high pressure hose or mend it with tape or any other device. A repaired hose cannot contain the high pressure fluid.

MOWING PARTS HAZARD

Moving parts can pinch or amputate your fingers or other body parts. KEEP CLEAR of moving parts when starting or operating your system. Disconnect the power source and relieve pressure by following the Pressure Rellef Procedure

on page 2 before checking or servicing your system t o prevent

the pump from cyciing accidentally.

TERMS

WARNING: Alerts user to avoid or correct conditions that could cause bodily injury.

HANDLE AND ROUTE HOSES CAREFULLY. DO not pull on hoses to move equipment. 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 temperatures above 1 W F

(82OC) or below -4O'F (-40°C).

Hose G r o u n d i n g Continuity

Proper hose grounding continuity is essential t o maintaining a grounded spray system. Check theelectrical resistanceof your air and 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 resistance limits. Use a resistance meter in the ap- propriate range for your hose to check the resistance. If the resistance exceeds the recommended limits, replace it im- mediately. An ungrounded or poorly grounded hose can make your system hazardous. Also read FIRE

HAZARD, above.

OR EXPLOSION

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 1928-should be consulted.

INSTALLATION

NOTE:

Numbers in parentheses in the text refer to the reference numbers in the drawings.

WARNING

Be sure your system has valve and

a

bleed-type master air

a

fluid drain valve. These two ac- cessories help reduce the risk of serious bodily in- jury, including fluid injection; splashing in the eyes; or injury from moving parts, If you are ad- justing or repairing the pump or gun.

1. The b/eed-type master eir valve relieves air trap; ped between this valve and the pump after the air regulator is shut off. Trapped air can cause the pump to cycle unexpectedly.

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

J

1. Before installing the spray tip, start the pump and flush it according to the instructions supplied with your pump or sprayer.

2. Follow the Pressure Relief

Procedure on page 2.

OPERATION

WARNING

To reduce the risk of serious bodily injury, in- cluding fluid injection or splashing in the eyes or on the skin, always follow the Pressure Relief Pro-

cedure on page 2

before checking, servicing, in- stalling, removing, changing or cleaning spray tips or any part of the gun or system.

Whenever you stop spraying for a moment, engage the gun safety latch. See

Fig 2.

1. Start the pump. Adjust the fluid pressure's0 the spray is completely atomized. Always use the lowest pressure necessary to get the desired results.

Higher pressure may not improve the spray pattern and will cause premature tip and pump wear.

2. If adjusting the pressure does not give a good spray pattern, try another tip size. Be sure to relieve pressure completely before changing tips.

3. Use a full-open, full-close trigger action. Hold the gun about 14 in. (350 mml from and at right angles to the work surface. Don't swing the gun in an arc.

Practice to find the best length and speed of stroke.

Adjust the Spray Pattern

1. To adjust the spray pattern direction, follow the

Pressure Relief

Procedure on page 2.

Engage the

safety

latch and loosen the tip guard retaining nut.

Turn the spray tip so the groove is horizontal for a horizontal spray pattern, and vertical for

a

vertical pattern.

2. The spray tip orifice size and spray angle determines the coverage and size of pattern. When more coverage is needed, use a larger spray tip rather than increasing fluid pressure.

3. With the gun safety latch engaged, unscrew the tip guard (3) (21 in the nut of the tip guard and screw the assembly firmly onto the gun. Tighten with a wrench. See Fig 1.

NOTE:

Failure to install the tip gasket (2) will result in leaking.

4. Strain.the fluid you are spraying if it contains par- ticles which could clog the spray tip.

Cleaning end Clearing the Spray Tip

WARNING

To reduce the risk of

a

fluid injection or splashing in the eyes or on the skin, DO NOT hold your hand, body, or a rag in front of the spray tip when cleaning or checking

a

clogged tip. Always point the gun toward the ground or into

a

waste con- tainer when checking to see if the spray tip is cleared.

DO NOT try to "blow back" paint; this is NOT an air spray gun.

A

DO NOT wipe fluid build-up off the gun or spray tip until pressure is relieved. See the Pressure

Relief Procedure on page

2.

Clean off the front of the tip frequently during the day's operation and at the end of the work day. Always follow

the Pressure Relief Procedure on page 2.

Then use a solvent soaked brush to clean the spray tip and to keep
