Safety Information
WARNING: Failure to heed these warnings may result in personal injury and/or property damage.
- Read and understand all instructions and warnings in this manual before using this product.
- Do not exceed rated capacity. The jack's capacity is 3.5 tons (7,000 lbs).
- Use only on a hard, level surface. Avoid using on asphalt or soft ground, which may not support the load.
- This is a lifting device only. Immediately after lifting, support the vehicle with appropriate jack stands. Do not work under a vehicle supported only by a jack.
- Center the load on the saddle. Off-center loads can cause the jack to tip.
- Do not move the vehicle while it is on the jack.
- Wear ANSI-approved safety goggles and heavy-duty work gloves during use.
- Keep hands and feet clear of the jack's moving parts and the vehicle's wheels.
- Ensure the vehicle's parking brake is engaged and wheels are chocked before lifting.
- Do not modify the jack. Any modifications can compromise safety and void the warranty.
- Inspect the jack before each use. Do not use if any parts are damaged, bent, or cracked.
- California Proposition 65 Warning: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
Components
Familiarize yourself with the main components of your hydraulic floor jack:
- Lifting Arm: The primary moving component that raises and lowers the saddle.
- Saddle: The circular pad at the top of the lifting arm, designed to contact the vehicle's lifting point.
- Handle Socket: Where the two-piece handle is inserted.
- Release Valve: Controls the lowering of the jack. Turning it counter-clockwise lowers the jack.
- Piston Pump: The hydraulic mechanism that generates lifting force.
- Foot Pedal: Allows for quick lifting of the saddle to the vehicle's lifting point without pumping the main handle.
- Frame: The main body of the jack, providing structural support.
- Casters (Wheels): Steel wheels for easy maneuverability. Two swivel casters at the rear and two fixed casters at the front.

Setup
Before first use, perform the following steps:
- Unpacking: Carefully remove the jack and all components from the packaging. Inspect for any shipping damage.
- Handle Assembly: Insert the two-piece handle into the handle socket. Ensure it is fully seated and secured.
- Bleeding the Hydraulic System (Initial Setup):
- With the jack in the fully lowered position, locate the release valve.
- Turn the release valve counter-clockwise one full turn to open it.
- Pump the handle vigorously 10-15 times to purge any air from the hydraulic system.
- Turn the release valve clockwise to close it.
- Test the jack by lifting and lowering it a few times to ensure smooth operation.
Operating Instructions
Always follow safety guidelines before and during operation.
- Preparation:
- Park the vehicle on a hard, level surface.
- Engage the vehicle's parking brake.
- Place chocks on the wheels that will remain on the ground.
- Consult your vehicle's owner's manual for recommended lifting points.
- Positioning the Jack:
- Ensure the release valve is fully closed by turning it clockwise.
- Roll the jack under the vehicle, aligning the saddle directly under the designated lifting point.
- Use the foot pedal to quickly raise the saddle until it makes contact with the vehicle's lifting point.

- Lifting the Vehicle:
- Pump the handle up and down to raise the vehicle to the desired height.
- Lift only high enough to place jack stands.
- Securing the Vehicle:
- Once the vehicle is lifted, immediately place appropriately rated jack stands under the vehicle's designated support points.
- Slowly open the release valve by turning it counter-clockwise, allowing the vehicle to rest securely on the jack stands.
- Remove the hydraulic jack.
- Lowering the Vehicle:
- Ensure the area around the vehicle is clear.
- Reposition the jack under the lifting point.
- Slightly raise the vehicle off the jack stands.
- Remove the jack stands.
- Slowly turn the release valve counter-clockwise to lower the vehicle to the ground in a controlled manner.
- Once fully lowered, remove the jack.
Maintenance
Regular maintenance ensures the longevity and safe operation of your jack.
- Lubrication: Periodically lubricate all moving parts, including the pivot points, casters, and handle mechanism, with light machine oil.
- Hydraulic Fluid: Check the hydraulic fluid level every 6 months. To check, fully lower the jack, remove the oil filler plug, and ensure the fluid is level with the bottom of the filler hole. Use only high-quality hydraulic jack oil. Do not use brake fluid or motor oil.
- Cleaning: Keep the jack clean and free of dirt, grease, and debris. Wipe down the piston rod to prevent contaminants from entering the hydraulic system.
- 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, leaks, or wear. Pay close attention to welds, casters, and the hydraulic cylinder. If any damage is found, do not use the jack and have it repaired by a qualified technician.
