Using the Bosch ITSA12B is easy. First, insert the 1/4' hex shank into your impact driver. Then, attach the 1/2' socket to the other end of the adapter. You're all set to tackle high - torque tasks. When using it, don't use excessive force beyond its capacity to avoid breakage. For maintenance, keep it clean after each use. Wipe off any dirt or debris. You can also store it in a dry place to prevent rust. This will help the adapter last longer and keep performing well.
