General Overhaul for motor-driven units
The validated, national accident prevention regulations must be observed and the measures to reach "safe
working periods (S.W.P.)" according to FEM 9.755.
After the "theoretical working time D" has been elapsed, the owner/user must take motor driven devices out
of operation and effect a General Overhaul.
Further use of the equipment is only allowed after a licensed qualified person has proofed
that further use is possible without doubt
and
the conditions for further use have been determined
These conditions have to be written down in the test book.
The owner/user is responsible to make sure that these conditions are observed.
