•Storage Conditions:Store the jack in a dry, dust-free place. Avoid exposure to direct sunlight and rain.
•Pre-Use Inspection:Clean the jack thoroughly before use.Check the piston movement and ensure all components are flexible and undamaged.Verify that the hydraulic fluid is clean and free from contaminants.
•Placement and Support:Place the jack on a flat, solid surface. On soft ground, use a pad to increase the contact area.Place a wooden board between the jack and the object to prevent damage and slippage.
•Load Capacity:Do not exceed the rated capacity of the jack.Do not extend the handle or use multiple people to apply pressure.Ensure the lift height does not exceed the marked limit on the cylinder or piston. If no markings are present, do not lift higher than three-quarters of the screw thread or oil plug height.
•Operation Safety:Initially lift the object slightly to check the stability of the base and the vertical alignment of the jack.If the jack is not stable or aligned, lower it and reposition before continuing.As the object rises, place safety boards or iron plates underneath to prevent sudden drops due to oil leakage.When lowering the jack, slowly open the release valve to allow the piston to descend gradually. Avoid sudden drops to prevent damage to internal components and potential injury.
•Multiple Jacks:If using multiple jacks simultaneously, ensure they are uniformly controlled and descend at the same rate to avoid tilting and accidents.Consider using a central oil pump for synchronized operation if possible.
