STARTING OF COMBUSTION ENGINES (starting of free-piston combustion engines F02B 71/02 ; starting of gas-turbine plants F02C 7/26); STARTING AIDS FOR SUCH ENGINES, NOT OTHERWISE PROVIDED FOR [2013‑01]
NOTE
-
Attention is drawn to the notes preceding class F01.

The starting of engines which are not explicitly stated to be combustion engines will be classified in this subclass insofar as their starting is equivalent to that of combustion engines.
