This image highlights the quality aspects of the jack stands' construction. It shows four key elements: Robotic Welding for accuracy, Powder Coating for resistance to elements, the use of Heavy Duty Steel for durability, and the Pyramidal Structure design for inherent strength.

3. Setup and Assembly

The TCE AT43002AU jack stands come pre-assembled and ready for use. Before first use, and periodically thereafter, inspect each stand for any signs of damage, wear, or deformation. Ensure all components are securely in place and functioning correctly.

1. Unpack: Carefully remove the jack stands from their packaging.
2. Inspect: Check for any shipping damage. Verify that the ratchet bar moves freely and the locking pin is present and functional.
3. Familiarize: Understand the operation of the ratchet bar and the double locking pin before placing any load on the stands.

4. Operating Instructions

Follow these steps for safe and effective use of your TCE jack stands:

1. Prepare the Vehicle: Park the vehicle on a hard, level surface. Engage the parking brake and block the wheels that will remain on the ground.
2. Lift the Vehicle: Use a suitable vehicle jack to lift the vehicle to the desired height. Refer to your vehicle's owner's manual for proper jacking points.
3. Position Jack Stands: Place the jack stands directly under the vehicle's designated support points (e.g., frame rails, axle housing). Ensure the stands are centered and stable.
4. Adjust Height: Raise the ratchet bar to the desired height. The sawtooth design allows for quick adjustments. Ensure both jack stands are set to the same height.
5. Engage Double Lock: Insert the removable locking support pin through the appropriate hole in the main column and the ratchet bar. This provides an additional layer of security.
6. Lower Vehicle onto Stands: Slowly and carefully lower the vehicle onto the jack stands. Ensure the vehicle's weight is fully supported by the stands before removing the jack.
7. Verify Stability: Gently rock the vehicle to confirm it is stable and securely resting on both jack stands.
8. Removal: To remove the vehicle, reverse the process. Lift the vehicle slightly with the jack, remove the locking pins, lower the ratchet bars, and then remove the jack stands. Finally, lower the vehicle completely to the ground.

5. Maintenance

Proper maintenance ensures the longevity and safe operation of your jack stands:

• Regular Inspection: Before each use, inspect the jack stands for cracks, bends, corrosion, or any other damage. Pay close attention to welds, the ratchet bar, and the locking pin. Do not use damaged jack stands.
• Cleaning: Keep the jack stands clean and free of dirt, grease, and debris. Wipe down with a clean cloth after use.
• Lubrication: Periodically apply a light coat of general-purpose grease or oil to the moving parts of the ratchet mechanism to ensure smooth operation.
• Storage: Store jack stands in a dry, clean area, away from moisture and corrosive materials. Store them in a retracted position to minimize exposure of the inner components.

6. Troubleshooting

If you encounter issues with your jack stands, consider the following:

• Stands Not Holding Height:
  • Ensure the ratchet bar is fully engaged in a tooth.
  • Verify the locking support pin is correctly inserted.
  • Check for damage to the ratchet teeth or the locking pin. If damaged, discontinue use.
• Difficulty Adjusting Height:
  • Clean any dirt or debris from the ratchet mechanism.
  • Apply a light lubricant to the moving parts.
  • Ensure no load is on the stand when attempting to adjust height.
• Stands Wobble or Are Unstable:
  • Ensure the ground surface is hard, flat, and level.
  • Verify the vehicle's weight is evenly distributed on both stands.
  • Check for any bent or damaged legs or base. If damaged, discontinue use.
