Mount the four alignment heads securely to the wheel rims. The system will automatically detect them. Roll the vehicle back and then forward slightly to settle the suspension, then apply the brakes as instructed. The 3D cameras capture the positions of the heads, and within seconds, you’ll see live readings for front and rear toe, camber, and caster. The display clearly shows current measurements versus target specifications in an easy-to-read color-coded format (often red for out-of-spec, green for in-spec).

Step 4: Advanced Techniques

For experienced users, the system offers advanced functions like set-back measurement, thrust angle alignment for the rear axle, and detailed printout customization for customer reports. You can also create custom alignment specifications for modified vehicles. Utilizing the multi-screen sync feature to display readings on a large wall-mounted monitor can greatly improve communication with a technician making the adjustments.
