How to Use the COATS QC20 Clamps for Accurate Alignments

Performing precise wheel alignments starts with the right tools—and COATS delivers with the QC20 Tire Clamps designed for use with the CWA 6500 3D Aligner. These specialized clamps improve accuracy, simplify the setup, and enhance your shop’s efficiency when used correctly. This step-by-step guide will help you understand when and how to use the QC20 clamps for optimal alignment results.

Choosing the Right Clamp: QC20 vs. Traditional

When it comes to choosing between QC20 and traditional clamps, the tire’s size and sidewall construction are key deciding factors.

• QC20 Clamps are ideal for low-profile tires (60 series and under).

• For tires above 60 series or those with floppy sidewalls, traditional clamps are often more effective and secure.

Understanding this distinction helps ensure both the accuracy of the alignment and the safety of the setup.

Preparing for Installation: Tire Pressure First

Before installing any clamps, it’s essential to:

• Adjust the tire pressure to the manufacturer’s recommended specifications.

• Ensure the tire is in optimal condition to receive the clamp without causing deformation or misreading during alignment.

This step is crucial for accurate compensation and alignment.

How to Install and Adjust the QC20 Clamps

Installing the QC20 clamps is straightforward but must be done with attention to detail:

1. Adjust the clamps to grip securely around the tire.

2. Ensure the clamp is parallel to the lift platform.

3. Turn the wheel until the clamp is tight and secure.

4. Activate the clamping lock switch to hold the clamp in place.

🔒 Tip: Once the clamp is in position, avoid disturbing or repositioning it—any shift can result in incorrect alignment readings.

Setting the CWA 6500 to QC20 Mode

Before beginning the alignment process, make sure your CWA 6500 aligner is set to QC20 mode. To verify:

• Look for the clamp icon at the bottom of the aligner screen.

• Click or confirm the icon to enable QC20 compatibility.

Failing to enable the correct clamp mode can compromise the accuracy of your alignment results.

Recompensating After Lifting or Lowering

If the vehicle is lifted or lowered at any point during the alignment procedure:

• Recompensate the vehicle before continuing.

• This ensures the aligner accounts for any movement or shifting caused by changes in height or position.

Skipping this step can lead to errors in readings and misalignments.

Using Split Roll Mode with QC20 Clamps

When using split roll mode, avoid pushing or pulling directly from the tire:

• Never roll from the tire with QC20 clamps attached.

• Ideally, push the vehicle from the rear to prevent clamp movement.

Following proper handling techniques maintains the accuracy of your alignment process and protects your equipment from unnecessary stress.
