Setup

1. Unpacking: Carefully remove the jack and all components from the packaging.
2. Handle Assembly: Insert the handle into the handle socket on the jack. Ensure it is securely seated and locked into place if a locking mechanism is present.
3. Bleeding the Hydraulic System (Initial Use):
   • With the jack fully lowered, open the release valve by twisting the handle counter-clockwise.
   • Pump the handle several times to circulate the hydraulic fluid and remove any trapped air.
   • Close the release valve by twisting the handle clockwise.
   • Test the jack by lifting it to its maximum height and then lowering it. Repeat if necessary until operation is smooth.

Operating Instructions

Lifting a Vehicle:

1. Preparation: 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. Positioning the Jack: Locate the manufacturer-recommended lifting points on the vehicle. Position the jack's saddle directly under the lifting point.
3. Lifting: Close the release valve by twisting the handle clockwise until it is tight. Pump the handle to raise the jack. The double piston pump allows for quick lifting.

4. Using Jack Stands: Once the vehicle is at the desired height, immediately place appropriately rated jack stands under the vehicle's designated support points. Slowly lower the vehicle onto the jack stands using the release mechanism.
5. Removing the Jack: Once the vehicle is securely supported by jack stands, fully lower the jack and remove it from under the vehicle.

Lowering a Vehicle:

1. Preparation: Ensure the area around the vehicle is clear.
2. Re-engage Jack: If the vehicle is on jack stands, raise the vehicle slightly with the floor jack so the jack stands can be safely removed.
3. Controlled Lowering: Slowly twist the handle counter-clockwise to open the release valve. The unique "lift & twist" controlled lowering system allows for precise and controlled descent. Do not open the valve too quickly, as this can cause the vehicle to drop rapidly.

4. Complete Lowering: Continue to lower the vehicle until it is fully on the ground.
5. Remove Jack: Once the vehicle is fully lowered, remove the jack.

Maintenance

Regular maintenance ensures the longevity and safe operation of your jack.

• Cleaning: Keep the jack clean and free of dirt, grease, and debris. Wipe down the hydraulic ram and other moving parts after each use.
• Lubrication: Periodically lubricate pivot points and wheel axles with light machine oil.
• Hydraulic Fluid: Check the hydraulic fluid level regularly. If low, add high-quality hydraulic jack oil. Do not use brake fluid or motor oil. To check/add fluid:
  • Ensure the jack is fully lowered.
  • Locate the oil filler plug (refer to diagram in product manual if available).
  • Remove the plug and check the fluid level. It should be just below the filler hole.
  • Add fluid slowly until the correct level is reached.
  • Replace the filler plug securely.
• Storage: Store the jack in a clean, dry place with the ram fully retracted to prevent corrosion and extend seal life.
• Inspection: Before each use, inspect the jack for any signs of damage, wear, or leaks. Pay close attention to welds, wheels, and hydraulic hoses.
