Stihl MS 441 Specifications Tightening Torques

DG screws are used in the polymer and light-alloy components. These screws form a permanent thread when they are installed for the first time. They can be removed and installed as often as necessary without detrimentally affecting the strength of the screwed assembly, providing the specified tightening torque is observed. For this reason it is essential to use a torque wrench when making adjustments from the Stihl MS 441 Specifications.
