Safety Information Warning: when using tools, basic safety precautions should always be followed to reduce the risk of personal injury and damage to equipment. Read all instructions before using this tool. 1. Keep work area clean. Cluttered areas invite injuries. 2. Observe work area conditions. Do not use machines or power tools in damp or wet locations. Don’t expose to rain. Keep work area well lit. Do not use electrically powered tools in the presence of flammable gases or liquids. 3. Keep children away. Children must not be allowed in work area. Do not let them handle machines, tools or extension cords. 4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit rust. Always lock up tools and keep them out of reach of children. 5. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger industrial tool. The tool will perform better and more safely at the rate for which it was intended. Do not modify this tool or used for a purpose for which it was not designed. 8192106manual 10/19/07 11:23 AM Page 3 6. Dress properly. Do not wear loose clothing or jewellery as they can be caught in moving parts. Protective, electrically non-conductive clothes and non-skid footwear are recommended when working. Tie back long hair. 7. Use eye, face and ear protection. Always wear ANSI approved impact safety goggles. Wear a full face shield if you are producing metal filings or wood chips. Wear an ANSI approved dust mask or respirator when working around metal, wood and chemical dusts and mists. Wear ANSI approved earplugs. 8. Do not over reach. Keep proper footing and balance at all times. Do not reach over or across running machines. 9. Maintain tools with care. Keep tools clean and in good condition for better and safer performance. Follow instructions for lubricating and changing accessories. Inspect tool fitting sand hoses periodically and, if damaged, have them repaired by an authorized technician. The handles must be kept clean, dry and free from oil and grease at all times. 10. Disconnect power. Disconnect from air pressure source when not in use. 11. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are removed from the tool or machine work surface before connecting it. 12. Avoid unintentional starting. Be sure that the butterfly throttle switch is in the neutral, OFF position when not in use and before attaching to pressure source. Do not carry the tool with a finger near or on the switch. 13. Stay alert. Watch what you are doing and do not operate any tool when you are tired. 14. Check for damaged parts. Before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not use the tool if the butterfly throttle switch does not function properly. 8192106manual 10/19/07 11:23 AM Page 4 15. Guard against electric shock when working on electrical equipment, such as your air compressor. Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures. 16. Replacement parts and accessories. When servicing, use only identical replacement parts. Only use accessories intended for use with this tool. 17. Do not operate tool if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgement or reflexes are impaired while taking drugs. If there is any doubt, do not operate the tool. 18. Use proper size and type of air pressure line and fittings. The recommended air line for this tool is 3/8" I.D. with up to 90 PSI. 1/4" NPT air inlet is the recommended size. 19. Maintenance. For your safety, service and maintenance should be performed regularly by a qualified technician. 20. Maintain a proper regulator and moisture trap in the air line at all times. Note: Performance of this tool may vary depending on variations in local air pressure. Warning: The brass components of this product contain lead, a chemical known to the state of California to cause birth defects (or other reproductive harm.) Unpacking Examine the condition of the impact wrench. If any parts are missing or broken, please contact your nearest Princess Auto location. 8192106manual 10/19/07 11:23 AM Page 5 Operation 1. Install a standard 1/4" air connector (not included) to the air inlet (36.) First wrap the threaded portion of the air connector with pipe thread seal tape. Tighten securely. 2. Attach a standard quick connector (not included) to the 3/8" air pressure source hose. Attach the air hose to the impact wrench. Note: If not using an automatic in line oiler, add a few drops of air tool oil to the air inlet before attaching the air hose. Add a few more drops of oil after every hour of continual use. 3. Set the air pressure regulator on the air compressor to 90 PSI. Warning: Do not exceed the recommended pressure of 90 PSI. Damage to the tool, and potential personal injury or property damage may result. 4. Check the air line and its connections for air leaks. If there are any, repair them before using the tool. Note: Turn off the air compressor and disconnect the air pressure hose before changing sockets or making any adjustments to this tool. Severe injury or property damage may otherwise result. Warning: This tool generates considerable torque when in use. Always hold the tool with both hands when using, and brace yourself to resist the torque which will be delivered to the work piece. 5. Select the appropriate size 3/8" drive impact socket (not included) for the job. Push and snap the socket onto the anvil (9). Note: Impact sockets must be rated for 9,000 RPM or greater. 6. Set the direction of the air impact wrench to Forward or reverse as in the figure below. By moving the throttle lever “butterfly”(5) to the right, the tool is set to operate forward. The amount of torque can be controlled by rotating the regulator (38). There are settings from 1 to 8, indicating increasing torque. Rock the throttle lever butterfly to the left to reverse the direction of the tool. 8192106manual 10/19/07 11:23 AM Page 6 Note: Forward refers to clockwise rotation, and reverse refers to counterclockwise rotation of the anvil. Note: The actual torque delivered at each setting will depend on the air pressure supplied to the tool. Test the actual torque by tightening a nut or bolt at each setting, then observing the resultant torque with a mechanical torque wrench (not included.) 7. If installing a nut or bolt, set it as tight as possible by hand before tightening with the impact wrench. 8. Place the socket (not included) over the fastener. 9. Grip the impact wrench tightly with both hands, and press the throttle lever butterfly to the right. The tool will operate and tighten the fastener. 10. When the fastener is tightened, release the throttle lever butterfly and remove the tool from the fastener. 11. If possible, check the actual torque with a mechanical torque wrench. 12. To remove a fastener, press the throttle lever butterfly to the left. The tool will loosen the fastener. Note: always check to ensure thread direction of any fastener before attempting to install or remove it. 13. When finished with the tool, turn off the air compressor and disconnect the air hose. Put the impact wrench away in a safe storage area. Maintenance 1. The impact wrench should be kept clean and dry. 2. When not in use, store the tool is a suitable place where it will not be exposed to water, corrosive material, or being knocked about. 3. If not using an inline oiler, inject a few drops of air tool oil into the air inlet of the tool and the oiler screw (3) port after every hour of continuous use. 4. If the tool looses power or air leaks are noticed, take it to a certified technician for servicing. All repairs should be performed by a qualified service technician. 8192106manual 10/19/07 11:23 AM Page 7 Parts List No. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21.
