1. Turn the lower arm adjusting screw to make the wheels move left and right; 2. Adjust the lower arm wheel side screw to make the wheel move inward; 3. Adjust the bolt connecting the shock absorber and the claw, and adjust the inclination angle; 4. If it exceeds the adjustment limit, it can be replaced with eccentric screws; 5. The tire inclination can be adjusted to the normal position by using eccentric screws. The function of camber angle of wheel is to distribute the dynamic bearing center between wheel and ground reasonably, so as to improve the service life of mechanical parts and reduce tire wear.
