4.12 ENGINE START-UP FROM EXTERNAL POWER SUPPLY
If the engine cannot be started from storage batteries due to their discharged state, it is per-
mitted to start the engine from an external power supply of from storage battery of another
tractor.
CAUTION!
In case of engine start-up from storage battery of another tractor, it is
necessary to strictly obey the following rules:
1. Start the engine up with switched off battery master switch of the tractor, which en-
gine is to be started from an external power supply. It is necessary to switch on the
battery master switch immediately upon the start of a steady operation of the engine
being started.
2. Engine of the tractor, which accumulator is used as an external power supply, shall
be shut off.
A failure to obey these rules can lead to increased discharge of storage battery

tor.
