2. Safety Instructions
Always prioritize safety when operating hydraulic lifting equipment. Failure to follow these instructions may result in serious injury or property damage.
- Read the Manual: Before operating the jack, thoroughly read and understand all instructions and warnings in this manual.
- Maximum Capacity: Never exceed the maximum rated lifting capacity of 2 tons (2000 kg).
- Stable Surface: Use the jack only on a hard, level, and stable surface capable of supporting the load. Avoid soft ground or uneven surfaces.
- Use Jack Stands: After lifting a vehicle, always support it immediately with appropriate jack stands before performing any work. Never rely solely on the hydraulic jack for support.
- Clearance: Keep hands, feet, and other body parts clear of moving parts and the area under the lifted load.
- Vehicle Stability: Ensure the vehicle is in park (or gear for manual transmission), the parking brake is engaged, and the wheels not being lifted are chocked.
- Regular Inspection: Inspect the jack for damage, leaks, or wear before each use. Do not use a damaged jack.
- Proper Storage: Store the jack in a clean, dry place, fully lowered, when not in use.

4. Setup
Follow these steps for initial setup before first use.
- Handle Assembly: Insert the smaller section of the operating handle into the larger section, ensuring it clicks securely into place. Then, insert the assembled handle into the jack's pump mechanism.
- Bleeding the Hydraulic System (Initial Use): To ensure proper operation, it is recommended to bleed any air from the hydraulic system before first use. To do this, open the release valve by turning the handle counter-clockwise. Pump the handle several times to its full extent. Close the release valve by turning the handle clockwise. The jack should now be ready for use.

5. Operating Instructions
Always follow safety guidelines before and during operation.
- Prepare the Vehicle: Park the vehicle on a hard, level surface. Engage the parking brake and place the transmission in park (or first gear for manual). Chock the wheels that will remain on the ground.
- Position the Jack: Locate the manufacturer-recommended lifting points on your vehicle. Position the jack saddle directly under the lifting point. Ensure the jack is stable and not at an angle.
- Lift the Vehicle: Close the release valve by turning the operating handle clockwise until it is firm. Pump the operating handle up and down to raise the jack saddle. Continue pumping until the vehicle is lifted to the desired height. Do not lift higher than necessary.
- 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 operating handle counter-clockwise to open the release valve. Once the vehicle is securely resting on the jack stands, remove the hydraulic jack.
- Lower the Vehicle: When work is complete, carefully raise the vehicle slightly with the hydraulic jack to remove the jack stands. Once jack stands are removed, slowly open the release valve by turning the operating handle counter-clockwise to lower the vehicle completely to the ground. Remove the jack once the vehicle is fully lowered.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your hydraulic jack.
- Hydraulic Fluid: Check the hydraulic fluid level periodically. If low, refill with a high-quality hydraulic jack oil. Do not use brake fluid or other non-specified fluids.
- Lubrication: Lubricate all moving parts, such as pivot points and wheels, with light machine oil as needed.
- Cleaning: Keep the jack clean and free from dirt, grease, and debris. Wipe down the ram and pump mechanism after each use.
- Storage: Store the jack in a dry, protected area, fully lowered, to prevent corrosion and damage.
7. Troubleshooting
Refer to this section for common issues and their potential solutions.
- Jack does not lift or lifts slowly:
- Check hydraulic fluid level and refill if necessary.
- Bleed air from the hydraulic system (refer to Section 4).
- Ensure the release valve is fully closed.
- Jack lowers too quickly or does not hold load:
- Ensure the release valve is fully closed.
- Check for hydraulic fluid leaks. If a leak is present, discontinue use and seek professional repair.
- Internal seal failure may require professional service.
- Difficulty moving the jack:
- Check wheels for obstructions or damage.
- Lubricate wheel axles if necessary.
If problems persist after attempting these solutions, contact a qualified service technician for assistance.
