Engine heating
P15N055
Do further heating of the engine when driving. Heating engine by lengthy idle run or abrupt
revolutions increase is harmful to the engine. If the temperature of coolant has not reached 45°C, do
not overcome engine revolutions over 2,000 rpm.
Error signalling
Indication of the limitation of the engine power and engine revolutions
Errors arising during tractor operation are indicated by
switching the corresponding signal lamp, acoustic signal
and error message in the instrument panel display.
If the error is indicated, the signal lamp still glows, even
though the display is switched to the next display.
If the error is not eliminated or the indicated state has not
returned to a normal state:
the corresponding signal lamp glows
when the tractor is switched off, the key in the switch box
is moved to position I and then the engine is started, the
corresponding signal lamp is switched on again and the
error message runs through the display.
1 - The signal lamp of a serious defect of the system (red).
2 - The signal lamp of a less serious defect of the system
(orange).
3 - Operational protection signal lamp (blue).
4 - Gearbox malfunction signal lamp (dark red). It glows
together with any of the signal lamps indicating errors, as
long as the error relates to the gearbox or the system of
travelling clutches.
More information in chapter Instrument panel.
