Safety Warnings and Precautions WARNING: When using tool, 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 lighted. Do not use electrically powered tools in the presence of flammable gases or liquids. 3. Keep children away. Children must never be allowed in the 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 out of reach of children. 5. Do not force tool. It will do the job better and more safely at the rate for which it was intended. Do not use inappropriate attachments in an attempt to exceed the tool capacity. 6. 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. There are certain applications for which this tool was designed. Do not modify this tool and do not use this tool for a purpose for which it was not intended. SKU 42947 For technical questions, please call 1-800-444-3353. Page 7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts. Protective, electrically non-conductive clothes and non-skid footwear are recommended when working. Wear restrictive hair covering to contain long hair. 8. Use eye 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 a NIOSH-approved dust mask or respirator when working around metal, wood, and chemical dusts and mists. 9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across running machines. 10. Maintain tools with care. Keep tools sharp and clean for better and safer performance. Inspect tool cords periodically and, if damaged, have them repaired by a qualified technician. 11. Disconnect power. Unplug motor when not in use. 12. Avoid unintentional starting. Be sure the switch is in the Off position when not in use and before plugging in. Do not carry any tool with the unit plugged in. 13. Stay alert. Watch what you are doing, use common sense. 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 any switch does not turn On and Off properly. 15. Guard against electric shock. 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. Use of any other parts will void the warranty. Only use accessories intended for use with this tool. Approved accessories are available from Harbor Freight Tools. 17. Do not operate tool if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not operate the tool. 18. Use proper size and type extension cord. If an extension cord is required, it must be of the proper size and type to supply the correct current to the tool without heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the tool. This tool requires use of an extension cord of 0 to 15 amps capability (up to 50 feet), with wire size rated at 16 AWG. Longer extension cords require larger size wire. If you are using the tool outdoors, use an extension cord rated for outdoor use (signified by “WA” on the jacket). 19. Maintenance. For your safety, service and maintenance should be performed regularly by a qualified technician. Note: Performance of this tool may vary depending on variations in local line voltage.

Warning: The warnings, cautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator. Vibration Hazard This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury: 1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical check-ups to ensure medical problems are not being caused or worsened from use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, nervous system disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any medical or physical symptoms related to vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible. 2. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury. 3. Wear suitable gloves to reduce the vibration effects on the user. 4. Use tools with the lowest vibration when there is a choice between different processes. 5. Include vibration-free periods each day of work. 6. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work. 7. To reduce vibration, maintain the tool as explained in this manual. If any abnormal vibration occurs, stop use immediately. REV 07j SKU 42947 For technical questions, please call 1-800-444-3353.
