The required (minimum) special tools are designated category A and B, and ensure the proper completion of routine maintenance and repair jobs. These tools must therefore be available in all Mercedes‑Benz workshops, regardless of size, performing such work.

Optional Special Tools

C - for component repairs.

The optional tools designated category C are recommended in addition to the required (minimum) tools, depending on the type and extent of the unit overhauls. These tools are also to accommodate large scale mechanical repair jobs. Their purchase is advised by MBUSA (but not required) and depends on the types of jobs performed by specific workshops.
