What are the operating steps for a wheel alignment instrument?

Below are the operating procedures for a wheel alignment instrument: 1. Check whether there are gaps or damages in the vehicle's suspension device, wheel bearings, steering system, etc. The maximum allowable tread depth difference for tires on the same axle is 2mm. The tire inflation pressure should comply with regulations. The vehicle should be equipped with full weight. 2. Drive the vehicle onto the four-post lift and stabilize it, ensuring the vehicle's center aligns with the lift and turntable center. Check and, if necessary, modify the vehicle specifications. 3. Operate strictly according to the steps displayed by the alignment instrument, with no omissions allowed. For example, perform wheel deviation compensation and tire inspection as required. 4. The adjustment of each wheel's alignment parameters (toe-in, camber angle) should comply with the requirements of the respective vehicle model's "service manual." Any parameters that do not meet the specified requirements should be adjusted (except for those that cannot be adjusted on the original vehicle).
When operating a wheel alignment machine, my usual steps are as follows: First, inspect the vehicle's suspension and tire conditions to ensure there is no damage or low tire pressure, as these could affect the results. Then, attach the wheel alignment clamps to each wheel and tighten them securely with clamping screws to prevent any looseness. Next, drive the vehicle onto the alignment platform, park it steadily, and engage the handbrake. Start the computer system, input the vehicle model year and parameter settings, and the machine will automatically calibrate. Once the screen displays the current angle data, I compare it with the standard values to check for deviations in camber, caster, and toe-in/toe-out. Begin adjustments by loosening bolts with a wrench, fine-tuning the tie rods or steering arms, and then lock them in place once aligned. Finally, rescan to confirm all data falls within the green zone, and conduct a test drive to ensure smooth steering. After each alignment, I remind customers to schedule regular wheel alignments to prevent uneven tire wear, improve fuel efficiency, and ensure safer, worry-free driving.
Operating the wheel alignment machine requires a step-by-step approach: First, check if the tire pressure is normal, as different vehicles have varying requirements—only standard pressure ensures accurate measurements. Next, attach the sensors to the wheel hubs, ensuring each one is securely clamped without any wobbling. Drive the vehicle onto the platform and park it steadily, then power on the machine and launch the software, inputting the specific model to select preset values. The measurement process then begins, with the screen displaying real-time parameters like camber, caster, and toe angles, while I record any deviations. During adjustments, follow the instructions to loosen bolts, adjust the length of the tie rods or the position of the steering knuckle, and tighten them while monitoring the data changes. After verification, run another test to ensure the data meets the standards. I always pay attention to equipment maintenance, such as cleaning the sensors to avoid misreadings. The entire process demands meticulousness—otherwise, improper adjustments can lead to steering wheel misalignment or accelerated tire wear. I often advise friends to get an alignment every 20,000 kilometers to catch minor issues early.
