General Safety

This is a high pressure dispensing gun. Fluid dispensed under high pressure could be injected through your skin and into your body. This could cause extremely serious bodily injury, including the need for am- putation. Also, fluid injected or splashed into the eyes or onthe skin can cause serious damage.

NEVER point gun at anyone or at any part of the body.

NEVER put hand or fingers over the nozzle.

NEVER try to stop or deflect leaks with your hand or body.

NEVER tty to ‘blow back” paint; this is NOT an air spray gun.

ALWAYS follow the Pressure Relief Procedure, at right, before cleaning or removing the nozzle or servicing any system equipment.

Medical Alert - Airless Spray Wounds

If any fluid appears to penetrate your skin, get EMERGENCY MEDI-

CAL CARE AT ONCE. DO NOT TREAT AS A SIMPLE CUT. Tell the doctor exactly what fluid was injected.

It is important to treat the injury surgically as soon as possible. Do not delay treafment to research loxicity. Toxicity is a concern with some exotic coatings injected directly inlo Ihe blood stream. Consultation with a plasticsurgeon or reconstruc- tive hand surgeon may be advisable.

Safety Latch

Whenever you stop dispensing, even for a moment, always fully release the trigger. This engagesthe gun’s safety latch and makesthe gun inop- erative. Failure to setthe safety latch can result in accidental triggering of the gun.

EQUIPMENT MISUSE HAZARD;:;i.- : ,. ~:::j:ili;i

Spray Nozzle Safety

Use extreme caution when cleaning or changing the nozzle. If the nozzle clogs while dispensing, fully release the trigger immediately.

ALWAYS follow the Pressure Relief Procedure, below, and then re- move the nozzle to clean it.

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

Pressure Relief Procedure

To reduce the risk of serious bodily injury, including fluid injection, splashing in the eyes or on skin, or injury from moving parts, alwaysfol- low this procedure whenever the dispensing equipment is shut off. when checking or servicing any part of system, when installing, clean- ing or changing nozzles and whenever you stop dispensing.

1. Fully release the gun trigger to set the safety latch.

2. Disconnect the power source.

3. Hold a metal part of the gun firmly to the side of a grounded metal waste container. Disengage the safety latch by pushing the latch in as you trigger the gun to relieve fluid pressure.

4. Fully release the gun trigger to set the safety latch.

5. Open the pump drain valve to help relieve fluid pressure in the pump, hose and gun. Triggering the gun to relieve pressure may not be sufficient. Have a container ready to catch the drainage.

8. Leave the drain valve open until you are ready to dispense again.

If you suspect that the nozzle or hose is completely clogged or that pressure has not been fully relieved after following the steps above,

VERY SLOWLY loosen the hose end coupling and relieve pressure gradually, then loosen completely. Now clear the nozzle or hose obstruction.

General Safety

Any misuse of the dispensing equipment or accessories, such as over- pressurizing. modiina hark. using incomoatiblechemicals and fluids, br using w&n or d&nag’ed parts, can caus’e them to rupture and result in serious bodily injury, including fluid injection and splashing fluid in the eyes or on the skin, or in fire, explosion or property damage.

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

CHECK the gun and all dispensing equipment regularly and repair or replace worn or damaged parts immediately.

Read and follow the fluid and solvent manufacturer’s literature regard- ing the use of protective eyewear, gloves, clothing, respirator and other equipment.

MOVING PARTS HAZARD ‘. :. ...:’

Moving parts can pinch or amputate your fingers or other body parts.

. . .

System Pressure

DO NOT exceed 6000 psi (415 bar) MAXIMUM WORKING PRESSURE to the spray gun. Be sure that all dispensing equipment and accesso- ries are properly rated to withstand the pressures developed by your system. NEVER exceed the maximum working pressure of any compo- nent or accessory used in your system.

Fluid Compatibility

BE SURE all fluids and solvents used are chemically compatible with the

“Wetted Parts” shown in the TECHNICAL DATA on the back cover.

Always read the fluid and solvent manufacturer’s literature before using any fluids or solvents in your system.

2 307-004

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 mis- use, the high pressure spray emitted from it can cause a fluid injection injury or other serious bodily injury or property damage.

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 imme- diately. DO NOTtryto 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. Do not use fluids or solvents which are not oompat- ible with the inner tube and cover of the hose. DO NOT expose hose to extreme temperatures; check with your hose supplier to determine temperature tolerances.

Fluid l-lose 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 resistance 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 immedi- ately. An ungrounded or poorly grounded fluid hose can make your system hazardous. Also read FIRE OR EXPLOSION HAZARD, above.

Static electricity is created by the flow of fluid through the pump and hose. If every part of the equipment is not properly grounded, sparking may occur, and the system may become hazardous. Sparks 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 pumping in- doors or outdoors, and cause a fire or explosion, 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 feel even a slight shock while using this equipment. STOP SPRAYING IMMEDIATELY. Check for proper grounding of the entire system. Do not use the system again un- til the cause of the problem is identified and corrected.

Grounding

To reduce the risk of static sparking, ground the pump and all other equipment used or located in the dispensing area. CHECK your local electrical code for detailed grounding instructions for your area and type of equipment and be sure to groundall of the following equipment:

1. Pump: ground the pump by connecting a grounding wire (12 ga minimum) from the pump’s grounding lug to a true earth ground.

3. Air compressor or hydraulic power supply: ground according to local code manufacturer’s recommendations.

5.

6.

7.

2.

4. a.

Fluid hoses: use only grounded hoses with a maximum of 509 feet

(150 m) combined hose length to ensure grounding continuity.

Refer to Hose Grounding Continuity, above.

Dispensing gun: obtain grounding through connection to a prop- erly grounded fluid hose and pump.

Fluid supply container: according to local code.

Object being sprayed: according to local code.

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 cardboard, which inter- rupts the grounding continuity.

To maintain grounding continuity when flushing or relieving pres- sure, always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.

FlUshlnQ Safety

Before flushing, be sure the entire system and flushing pails are prop- erly grounded. Refer to Grounding, above. Always use the lowest pos- sible fluid pressure, and maintain firm metal-to-metal contact between the gun and the grounded metal pail during flushing to reducethe risk of fluid injection injury, static sparking and splashing.

Ventilate the Spray Area

To prevent hazardous concentrations of toxic and/or flammablevapors. spray only in a properly ventilated spray area.

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.
