# Attaching and balancing the tool when mounted on a bench

Do not use SMC 200 and SMC 300 with a bench stand.

1. Adjust the height of the arm relative to the work piece. It is recommended to mount the arm attachment at the same height as where the torque is applied.

   - SMC 12/25 (M6) - 10 Nm

   - SMC 50/100 (M8) - 24 Nm

4. Install the set screw on the tool holder and tighten it to 2.5 Nm.
