Safety Information
WARNING: Failure to follow these instructions may result in serious injury or property damage.
- Always read and understand the entire manual before operating the jack.
- Do not exceed the rated capacity of 3 tons (6,000 lbs).
- Use only on a hard, level surface.
- Always use jack stands to support the vehicle immediately after lifting. The jack is a lifting device only, not a vehicle support device.
- Ensure the vehicle is in park (or gear for manual transmission) and the parking brake is engaged. Block wheels that are not being lifted.
- Center the load on the saddle. Off-center loads can cause the jack to tip.
- Keep hands and feet clear of moving parts and the area under the vehicle.
- Do not modify the jack or use it for purposes other than its intended use.
- Wear appropriate personal protective equipment, such as safety glasses.
- Inspect the jack before each use for any damage, leaks, or loose parts. Do not use if damaged.
- Lower the load slowly and carefully.
Setup and Initial Preparation
Before using your BIG RED T830025-1 floor jack, ensure it is properly assembled and prepared.
- Connect the Handle: Insert the two handle sections together. Place the assembled handle into the handle socket on the jack.
- Secure the Handle: Turn the handle clockwise until it is fully tightened and secured in the socket. This also closes the release valve for lifting.
- Purge Air from Hydraulic System (Bleeding):
- With the jack fully lowered, remove the oil filler plug (if present, refer to diagram in full manual).
- Pump the handle rapidly 10-15 times without a load.
- Replace the oil filler plug. This helps remove any trapped air.

Operating Instructions
Follow these steps for safe and effective operation of your floor jack.
Lifting a Vehicle:
- Prepare the Vehicle: Park the vehicle on a hard, level surface. Engage the parking brake and place the transmission in park (or lowest gear for manual). Block the wheels that are not being lifted.
- Position the Jack: Roll the jack under the vehicle, positioning the saddle directly under the manufacturer's recommended lifting point. Consult your vehicle's owner's manual for proper lifting points.
- Raise the Vehicle: With the handle fully tightened clockwise (release valve closed), pump the handle up and down to raise the saddle. Continue pumping until the vehicle is lifted to the desired height.
- Install Jack Stands: Immediately after lifting, place appropriately rated jack stands under the vehicle's frame or designated support points. Ensure the vehicle is securely resting on the jack stands before performing any work.
- Slightly Lower Jack: Once jack stands are in place, slowly turn the handle counter-clockwise to slightly lower the jack until the vehicle's weight is fully supported by the jack stands. The jack should remain in contact with the vehicle as a secondary safety measure.
Lowering a Vehicle:
- Raise Vehicle Slightly: Pump the jack handle a few times to lift the vehicle slightly off the jack stands.
- Remove Jack Stands: Carefully remove the jack stands from under the vehicle.
- Lower Vehicle: Slowly turn the handle counter-clockwise to open the release valve. The vehicle will begin to lower. Control the lowering speed by adjusting how much you turn the handle.
- Remove Jack: Once the vehicle is fully lowered to the ground, remove the floor jack.

Maintenance
Regular maintenance ensures the longevity and safe operation of your floor jack.
- Lubrication: Periodically lubricate all moving parts with light machine oil.
- Hydraulic Oil Level: Check the hydraulic oil level every three months. 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 high-quality hydraulic jack oil if needed. Do not overfill.
- Cleaning: Keep the jack clean from dirt, grease, and corrosive materials.
- Storage: Store the jack in a dry, protected area with the ram fully retracted to prevent rust and seal damage.
- Inspection: Before each use, inspect for any signs of damage, leaks, or wear. Pay close attention to welds, wheels, and the hydraulic cylinder.
