3 7- and 10-Inch Air Motors with Air Valve 1 afety Qualified Personnel Intended Use Regulations and Approvals Read and follow these safety instructions. Task- and equipment-specific warnings, cautions, and instructions are included in equipment documentation where appropriate. Make sure all equipment documentation, including these instructions, is accessible to persons operating or servicing equipment. Equipment owners are responsible for making sure that Nordson equipment is installed, operated, and serviced by qualified personnel. Qualified personnel are those employees or contractors who are trained to safely perform their assigned tasks. They are familiar with all relevant safety rules and regulations and are physically capable of performing their assigned tasks. Use of Nordson equipment in ways other than those described in the documentation supplied with the equipment may result in injury to persons or damage to property. ome examples of unintended use of equipment include using incompatible materials making unauthorized modifications removing or bypassing safety guards or interlocks using incompatible or damaged parts using unapproved auxiliary equipment operating equipment in excess of maximum ratings Make sure all equipment is rated and approved for the environment in which it is used. Any approvals obtained for Nordson equipment will be voided if instructions for installation, operation, and service are not followed.

4 2 7- and 10-Inch Air Motors with Air Valve Personal afety 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 are intact and automatic interlocks are operating properly. Do not bypass or disarm any safety devices. Keep clear of moving equipment. Before adjusting or servicing moving equipment, shut off the power supply and wait until the equipment comes to a complete stop. Lock out power and secure the equipment to prevent unexpected movement. Relieve (bleed off) hydraulic and pneumatic pressure before adjusting or servicing 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 to the gun handle or other true earth ground. Do not wear or carry metallic objects such as jewelry or tools. If you receive even a slight electrical shock, shut down all electrical or electrostatic equipment immediately. Do not restart the equipment until the problem has been identified and corrected. Obtain and read Material afety Data heets (MD) for all materials used. Follow the manufacturer s instructions for safe handling and use of materials, 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 workplace that often cannot be completely eliminated, such as hot surfaces, sharp edges, energized electrical circuits, and moving parts that cannot be enclosed or otherwise guarded for practical reasons.

5 7- and 10-Inch Air Motors with Air Valve 3 High-Pressure Fluids High-pressure fluids, unless they are safely contained, are extremely hazardous. Always relieve fluid pressure before adjusting or servicing high pressure equipment. A jet of high-pressure fluid can cut like a knife and cause serious bodily injury, amputation, or death. Fluids penetrating the skin can also cause toxic poisoning. If you suffer a fluid injection injury, seek medical care immediately. If possible, provide a copy of the MD for the injected fluid to the health care provider. The National pray Equipment Manufacturers Association has created a wallet card that you should carry when you are operating high-pressure spray equipment. These cards are supplied with your equipment. The following is the text of this card: WARNING: Any injury caused by high pressure liquid can be serious. If you are injured or even suspect an injury: Go to an emergency room immediately. Tell the doctor that you suspect an injection injury. how him this card. Tell him what kind of material you were spraying. MEDICAL ALERT AIRLE PRAY WOUND: NOTE TO PHYICIAN Injection in the skin is a serious traumatic injury. It is important to treat the injury surgically as soon as possible. Do not delay treatment to research toxicity. Toxicity is a concern with some exotic coatings injected directly into the bloodstream. Consultation with a plastic surgeon or a reconstructive hand surgeon may be 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 causing more damage, and many other variables including skin microflora residing in the paint or gun which are blasted into the wound. If the injected paint contains acrylic latex and titanium dioxide that damage the tissue s resistance to infection, bacterial growth will flourish. The treatment that doctors recommend for an injection injury to the hand includes immediate decompression of the closed vascular compartments of the hand to release the underlying tissue distended by the injected paint, judicious wound debridement, and immediate antibiotic treatment.

6 4 7- and 10-Inch Air Motors with Air Valve Fire afety To avoid a fire or explosion, follow these instructions. Ground all conductive equipment in the spray area. Use only grounded air and fluid hoses. Check equipment and workpiece grounding devices regularly. Resistance to ground must not exceed one megohm. hut down all equipment immediately if you notice static sparking or arcing. Do not restart the equipment until the cause has been identified and corrected. Do not smoke, weld, grind, or use open flames where flammable materials are being used or stored. Do not heat materials to temperatures above those recommended by the manufacturer. Make sure heat monitoring and limiting devices are working properly. Provide adequate ventilation to prevent dangerous concentrations of volatile particles or vapors. Refer to local codes or your material MD for guidance. Do not disconnect live electrical circuits while working with flammable materials. hut off power at a disconnect switch first to prevent sparking. Know where emergency stop buttons, shutoff valves, and fire extinguishers are located. If a fire starts in a spray booth, immediately shut off the spray system and exhaust fans. hut off electrostatic power and ground the charging system before adjusting, cleaning, or repairing electrostatic equipment. Clean, maintain, test, and repair equipment according to the instructions in your equipment documentation. Use only replacement parts that are designed for use with original equipment. Contact your Nordson representative for parts information and advice.

7 7- and 10-Inch Air Motors with Air Valve 5 Action in the Event of a Malfunction Halogenated Hydrocarbon olvent Hazards Do not use halogenated hydrocarbon solvents in a pressurized system that contains aluminum components. Under pressure, these solvents can react with aluminum and explode, causing injury, death, or property damage. Halogenated hydrocarbon solvents contain one or more of the following elements: Element ymbol Prefix Fluorine F Fluoro- Chlorine Cl Chloro- Bromine Br Bromo- Iodine I Iodo- Check your material MD or contact your material supplier for more information. If you must use halogenated hydrocarbon solvents, contact your Nordson representative for information about compatible Nordson components. If a system or any equipment in a system malfunctions, shut off the system immediately and perform the following steps: Disconnect and lock out system electrical power. Close hydraulic and pneumatic shutoff valves and relieve pressures. Disposal Identify the reason for the malfunction and correct it before restarting the system. Dispose of equipment and materials used in operation and servicing according to local codes.

8 6 7- and 10-Inch Air Motors with Air Valve Description This section contains basic information about the air valve and air motors. 7- and 10-inch air motors, when joined to various hydraulic sections (pumps), create different hydraulic output ratios. The installation and operation of the air motors and air valves are dependent upon the other components they are to be used with. Refer to Table 1 to determine your pump ratio using the air motor and hydraulic section size.
