PROBLEM

Show/hide table

The 4D-1836 Secondary Engine Shutdown Switch needs to be replaced on certain 325D, 330D, M325D L MH, M325D MH Excavators. The existing shutdown switch can be accidently activated by a falling rod used for locking the batteries compartment door. If the engine is shut down while the machine is used with a magnet attachment, the load that is carried can be dropped which may cause serious injury.
