Sealey 3000CXD.V6 Instruction Manual

Ensure the jack is placed on a solid, level surface and position it under the vehicle's designated lifting points, typically found in the owner's manual or near the vehicle's frame.
The maximum lifting capacity of the Sealey 3000CXD.V6 Trolley Jack is 3 tonnes.
Check for proper placement under the lifting point, ensure the release valve is closed, and verify that the hydraulic oil level is adequate. If issues persist, inspect for airlocks in the hydraulic system.
Check the hydraulic oil level every six months or before each use if the jack is used frequently. Top up with the recommended oil if necessary.
Use only high-quality hydraulic jack oil. Avoid using brake fluid, alcohol, glycerin, detergent motor oil, or dirty oil.
To bleed air, open the release valve and pump the handle several times without load. Close the valve and test the jack's lifting action.
Regularly check for oil leaks, clean the jack after each use, store it in a dry location, and lubricate moving parts periodically.
This could be due to a worn or damaged seal. Inspect the seals and replace them if necessary. Also, ensure there are no airlocks in the system.
While the trolley jack can lift heavy objects, it is specifically designed for vehicles. Ensure any object lifted is stable and within the jack's weight capacity.
Ensure the handle is fully inserted and secure. If the issue persists, check for obstructions or damage to the pump mechanism.
