Do not operate tools and equipment in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools and equipment create sparks which may ignite flammables. 3. Keep bystanders, children, and visitors away while operating tools and equipment. Distractions can cause you to lose control. Protect others in the work area. Provide barriers or shields as needed. 4. Stay alert. Watch what you are doing, and use common sense when operating a power tool. Do not use tools and equipment while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury. 5. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. 6. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations. 7. Use safety equipment. Always wear ANSI approved safety impact goggles, safety shoes/boots, and heavy duty work gloves when using this product. 8. Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. 9. Store idle tools and equipment out of reach of children and other untrained persons. Tools and equipment are dangerous in the hands of untrained users. 10. Maintain tools with care. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired. 11. If damaged, have the tool serviced before using. Check for loose screws, misalignment or binding of moving parts, loose mounting, cracked or broken parts, low hydraulic oil level, and any other condition that may affect its safe operation. Many accidents are caused by poorly maintained tools. 12. Tool service must be performed only by qualified repair personnel.

Do not exceed the maximum lift capacity (3 Tons / 6,000 pounds) for this Floor Jack. Overloading the Jack could cause serious personal injury and/or property damage. 2. The Floor Jack is designed for intermittent use only. Do not use the Jack to support a vehicle over extended periods of time. The duration of the lifting job should be kept as short as possible. 3. Maintain labels and nameplates on the Floor Jack. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement. 4. Prior to using the Bottle Jack, make sure to read and understand all warnings, safety precautions, and instructions as outlined in the manufacturer’s instruction manual for the vehicle (or object) you will lift. 5. When lifting only one wheel, make sure to support the load immediately with one jack stand (not included) placed under the side of the vehicle being lifted. Align the saddle of the jack stand directly under the vehicle’s seam or a recommended lifting point. 6. When lifting the entire front end or rear end of a vehicle, make sure to support the load immediately with two jack stands. Align the saddles of the jack stands directly under the vehicle’s frame or recommended lifting points. Also make sure the jack stands are adjusted at the same height. 7. Make sure the Floor Jack is used only on a dry, oil/grease free, flat, level, ground surface capable of supporting the weight of the vehicle being lifted and any additional tools and equipment. 8. Do not work under the vehicle without properly supporting the vehicle with jack stands. Make sure the load and jack stands are stable before getting under a vehicle.

Always use the Floor Jack as far away from the roadside as possible. 11. Do not use the Floor Jack with the vehicle’s engine running. Make sure to place the vehicle’s transmission in “Park” (if automatic) or “1st Gear” (if manual). Then set the emergency brake, and block the tires opposite the tire being lifted. 12. Industrial applications must follow OSHA requirements. 13. Always keep hands, fingers, and feet away from all moving parts of the Floor Jack when applying or releasing a load. Remain clear of the vehicle being raised or lowered. People and animals should be kept at a safe distance when using the Jack. 14. Use extreme caution when applying or releasing a load. Never allow the load to suddenly release. Slowly and carefully apply and release the load. 15. Do not allow anyone in the vehicle while using the Bottle Jack. Keep all bystanders a safe distance away from the vehicle. 16. Never leave the Floor Jack unattended when the Jack is under a load. 17. Never support both ends of the vehicle at the same time. 18. Before lowering the Floor Jack, make sure tool trays, jack stands, and all other tools and equipment are removed from under the vehicle. 19.
