Specification:Material: Steel, N42 Magnet, Rubber, AlloyColor: YellowProcess: Coating, GalvanizingAssembly Required: YesMax. Lifting Capacity: 40 kg/880 lbsOperating Temperature: -40~80℃/-40~176 ℉Gross Weight: 21 lbs Product Size: 8.1*3.3*3.7 inHandle Length: 8.3 inPackage Included:1 * Magnetic Lifter1 * Handle1 * Hex Key1 * English ManualNotes:1. Please clean the surface of the steel plate before use to prevent the magnetic force from decreasing. Please do not use the product on a rough surface.2. Please do not control the handle without a steel plate under the magnetic lifter.3. There are strict requirements on the thickness of steel plate when lifting by the magnetic lifter. For example, when the magnet lifter adsorbs round steel, the adsorption capacity produced by the same magnetic force is about 30% of the flat workpiece, but the maximum is not more than 50%.4. Please note that the lifter should not be used at the edge of the lifter or vertically, and the centerline of the lifter should coincide with the centerline of the lifting object (i.e. balanced lifting).5. It is strictly forbidden to overload (beyond the parameter range) during the lifting process, and it is strictly forbidden to have people under the lifting object, and the operator needs to keep a sufficient safety distance from the lifted object.6. The lifted object should be kept basically stable in the lifting, and impact and large shaking are strictly prohibited.7. The ambient temperature of the product should not exceed 176 ℉, and it is strictly forbidden to contact objects higher than 176 ℉.8. Please read the operating manual completely before use.
