Setup

1. Unpacking: Carefully remove the jack and all accessories from the packaging. Inspect for any shipping damage.
2. Handle Assembly: Insert the two-piece handle into the handle socket on the jack. Secure it if there's a locking mechanism (refer to specific model design).
3. Bleeding the Hydraulic System (Initial Use):
   • Turn the release valve (usually at the base of the handle socket) counter-clockwise one full turn to open it.
   • Pump the handle 10-15 full strokes to remove any air from the hydraulic system.
   • Turn the release valve clockwise to close it.
   • Test the jack by lifting it to its full height and then lowering it. Repeat if necessary until smooth operation is achieved.
4. Check Oil Level: With the jack fully lowered and on a level surface, remove the oil filler plug. The oil level should be just below the filler hole. Add hydraulic jack oil if needed. Replace the plug securely.

Operating Instructions

Lifting a Vehicle:

1. Prepare the Vehicle: Park the vehicle on a hard, level surface. Engage the parking brake and place wheel chocks on the wheels that will remain on the ground.
2. Position the Jack: Locate the vehicle's designated lifting points (refer to your vehicle's owner's manual). Position the jack directly under the lifting point, ensuring the rubber pad or adapter is securely placed on the jack saddle.
3. Lift the Vehicle: Close the release valve by turning it clockwise until it is tight. Pump the jack handle to raise the vehicle to the desired height.
4. Secure with Jack Stands: Immediately place appropriately rated jack stands under the vehicle's designated support points. Slowly lower the vehicle onto the jack stands by gradually turning the release valve counter-clockwise. Ensure the vehicle is stable on the jack stands before performing any work.

Lowering a Vehicle:

1. Raise Slightly: If the vehicle is on jack stands, slightly raise the vehicle with the hydraulic jack to remove the load from the jack stands.
2. Remove Jack Stands: Carefully remove the jack stands from under the vehicle.
3. Lower the Vehicle: Slowly turn the release valve counter-clockwise to gradually lower the vehicle to the ground. Ensure the descent is controlled.
4. Remove Jack: Once the vehicle is fully lowered, remove the jack.
