The lamp comes on when the oil temperature in the hydraulic system reaches the critical value.
26
– Indicator lamp of oil level fall in the tank of hydraulic system for control over turns
and service equipment
The lamp comes on when the oil level falls below the critical value. Short-
term “flashing” of the
indicator lamp is allowed in case of travelling over road irregularities causing fluctuations of the
oil levelin the hydraulic tank.

– Switching-on of the end marker lights
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.
39
– Cooling fluid temperature gauge with built-in alarm signaling of the maximum limit
temperature value
for OM457LA (Mercedes) engine
– 95°С.
Cooling fluid working temperature:
for OM457LA (Mercedes) engine
– 90...95°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 OM457LA (Mercedes)engine shall be
within the range of 0.25
–0.5 MPa (2.5–5.0 kgf/cm
2
) at the nominal rotational speed and not less
than 0.05 MPa (0.5 kgf/cm
2
) at the minimum rotational speed.
42
– Indicator lamp of the emergency oil level of the engine (red)
43
– Indicator lamp of the engine stop demand (red)
The red-colored indicator lamps come up at the emergency values of the following parameters:
engine shaft rotational speed;
engine oil level;
