The key symbol in the upper position
– the lights and illumination are switched off.
The key symbol in the lower position
– the end marker lights switched on.

– Cooling fluid temperature gauge with built-in alarm signaling of the maximum limit
temperature value:
for
ЯМЗ-238НД5 engines – 100°С.
Within the temperature range of 90...99°С it is allowed to admit flashing of the temperature
gauge indicator lamp.
Cooling fluid working temperature:
for
ЯМЗ-238НД5 engines – 75...100°С.
Do not permit the engine operation on load at the cooling fluid temperature below 70°С.
40
– Alarm signaling switch
It is designed for simultaneous switching on the left and right turn signals in the flashing mode in
case of sudden stop of the tractor on the surfaced portion of the road. Switching-on is
performed by pressing the button. In doing so, the indicator lamp built into the switch button will
come on.
41
– Oil pressure indicator in the engine with built-in alarm signaling of the minimum
limit pressure value
The oil pressure in the mainline of the unit of heated
ЯМЗ-238НД5 engine shall be within the
range of 0.45
–0.6 MPa, (4.5–6 kgf/cm
2
) at the nominal rotational speed. The oil pressure at the
minimum rotational speed with
ЯМЗ-238НД5 engine shall not be less than 0.08 MPa
(0.8 kgf/cm
2
).
A short-term lighting of the built-in indicator lamp of the emergency oil pressure of the engine at
minimum rotational speed with the engine being heated.
