Personal Safety To prevent injury follow these instructions.

� Do not operate or service equipment unless you are qualified.

� Do not operate equipment unless safety guards, doors, or covers areintact and automatic interlocks are operating properly. Do not bypass ordisarm any safety devices.

� Keep clear of moving equipment. Before adjusting or servicing movingequipment, shut off the power supply and wait until the equipmentcomes to a complete stop. Lock out power and secure the equipment toprevent unexpected movement.

� Relieve (bleed off) hydraulic and pneumatic pressure before adjusting orservicing pressurized systems or components. Disconnect, lock out,and tag switches before servicing electrical equipment.

� While operating manual spray guns, make sure you are grounded.Wear electrically conductive gloves or a grounding strap connected tothe gun handle or other true earth ground. Do not wear or carry metallicobjects such as jewelry or tools.

� If you receive even a slight electrical shock, shut down all electrical orelectrostatic equipment immediately. Do not restart the equipment untilthe problem has been identified and corrected.

� Obtain and read Safety Data Sheets (SDS) for all materials used.Follow the manufacturer’s instructions for safe handling and use ofmaterials, and use recommended personal protection devices.

� Make sure the spray area is adequately ventilated.

� To prevent injury, be aware of less-obvious dangers in the workplacethat often cannot be completely eliminated, such as hot surfaces, sharpedges, energized electrical circuits, and moving parts that cannot beenclosed or otherwise guarded for practical reasons.

High-Pressure Fluids High-pressure fluids, unless they are safely contained, are extremelyhazardous. Always relieve fluid pressure before adjusting or servicing highpressure equipment. A jet of high-pressure fluid can cut like a knife andcause serious bodily injury, amputation, or death. Fluids penetrating theskin can also cause toxic poisoning.

If you suffer a fluid injection injury, seek medical care immediately. Ifpossible, provide a copy of the SDS for the injected fluid to the health careprovider.



The National Spray Equipment Manufacturers Association has created awallet card that you should carry when you are operating high-pressurespray equipment. These cards are supplied with your equipment. Thefollowing is the text of this card:

WARNING: Any injury caused by high pressure liquid can be serious. Ifyou are injured or even suspect an injury:

� Go to an emergency room immediately.

� Tell the doctor that you suspect an injection injury.

� Show him this card

� Tell him what kind of material you were spraying

MEDICAL ALERT—AIRLESS SPRAY WOUNDS: NOTE TO PHYSICIAN

Injection in the skin is a serious traumatic injury. It is important to treat theinjury surgically as soon as possible. Do not delay treatment to researchtoxicity. Toxicity is a concern with some exotic coatings injected directly intothe bloodstream.

Consultation with a plastic surgeon or a reconstructive hand surgeon maybe advisable.

The seriousness of the wound depends on where the injury is on the body,whether the substance hit something on its way in and deflected causingmore damage, and many other variables including skin microflora residingin the paint or gun which are blasted into the wound. If the injected paintcontains acrylic latex and titanium dioxide that damage the tissue’sresistance to infection, bacterial growth will flourish. The treatment thatdoctors recommend for an injection injury to the hand includes immediatedecompression of the closed vascular compartments of the hand to releasethe underlying tissue distended by the injected paint, judicious wounddebridement, and immediate antibiotic treatment.

Fire Safety To avoid a fire or explosion, follow these instructions.

� Ground all conductive equipment. Use only grounded air and fluidhoses. Check equipment and workpiece grounding devices regularly.Resistance to ground must not exceed one megohm.

� Shut down all equipment immediately if you notice static sparking orarcing. Do not restart the equipment until the cause has been identifiedand corrected.

� Do not smoke, weld, grind, or use open flames where flammablematerials are being used or stored.

� Do not heat materials to temperatures above those recommended bythe manufacturer. Make sure heat monitoring and limiting devices areworking properly.



Fire Safety (contd)

� Provide adequate ventilation to prevent dangerous concentrations ofvolatile particles or vapors. Refer to local codes or your material SDSfor guidance.

� Do not disconnect live electrical circuits when working with flammablematerials. Shut off power at a disconnect switch first to preventsparking.

� Know where emergency stop buttons, shutoff valves, and fireextinguishers are located. If a fire starts in a spray booth, immediatelyshut off the spray system and exhaust fans.

� Shut off electrostatic power and ground the charging system beforeadjusting, cleaning, or repairing electrostatic equipment.

� Clean, maintain, test, and repair equipment according to the instructionsin your equipment documentation.

� Use only replacement parts that are designed for use with originalequipment. Contact your Nordson representative for parts informationand advice.

Halogenated Hydrocarbon Solvent Hazards Do not use halogenated hydrocarbon solvents in a pressurized system thatcontains aluminum components. Under pressure, these solvents can reactwith aluminum and explode, causing injury, death, or property damage.Halogenated hydrocarbon solvents contain one or more of the followingelements:

Element Symbol Prefix

Fluorine F “Fluoro-”

Chlorine Cl “Chloro-”

Bromine Br “Bromo-”

Iodine I “Iodo-”

Check your material SDS or contact your material supplier for moreinformation. If you must use halogenated hydrocarbon solvents, contactyour Nordson representative for information about compatible Nordsoncomponents.

Action in the Event of a Malfunction If a system or any equipment in a system malfunctions, shut off the systemimmediately and perform the following steps:

� Disconnect and lock out system electrical power. Close hydraulic andpneumatic shutoff valves and relieve pressures.

� Identify the reason for the malfunction and correct it before restarting thesystem.
