2.6.3 The scale of the gauge indicating fuel volume in the tank 6 (figure 2.6.1) has the
divisions “0-1/4-1/2-3/4-1”. A signal lamp 5 (orange color) is built in the gauge scale, which
lights up when fuel volume in the tank drops below 1/8 of the total tank volume.
ATTENTION: DO NOT LET THE TANK BECOME EMPTY (THE GAUGE POINTER IS IN
THE ZONE OF ORANGE COLOR)!

6.4 The gauge scale of engine coolant temperature 8 has three zones:
- working – from 80 to 105 °
С
(green color);
- informational – from 40 to 80 °
С
(yellow color);
- emergency – from 105 to 120 °
С
(red color);
An emergency temperature lamp (red color) 7 is built in the scale, which operates in
two modes:
- lights up and operates in a flashing mode with coolant values from 109 up to and in-
cluding 112 °
С
.
- glows in a continuous mode with coolant temperature values from 113 °
С
and higher.
2.6.5 The oil pressure gauge scale in the engine lubricating system 9 has three zones:
- working – from 100 to 500 kPa (green color);
- emergency (two) – 0 to 100 kPa and from 500 to 600 kPa (red color).
A signal lamp of emergency oil pressure drop 10 (red color) is built in the gauge scale,
which lights up when the pressure drops below 100 kPa.
ATTENTION: WHEN THE COLD ENGINE IS STARTED THE PRESSURE CAN BE 600 kPa
and HIGHER!
ATTENTION: IF THE EMERGENCY PRESSURE LAMP IS ON WITH THE ENGINE RUNNING,
IMMEDIATELY STOP THE ENGINE AND ELIMINATE THE FAILURE!
2.7 Pilot lamps unit
2.7.1 General information
The pilot lamps unit 15 (figure 2.1.1) includes three lamps. The allocation scheme is
presented in figure 2. 7.1.
1 – pilot lamp to indicate that the air cleaner filter is clogged to the max. (orange color);
2 – pilot lamp to indicate emergency oil pressure drop in the system of hydrostatic power
steering (red color); 3 – pilot lamp to indicate operation of heating plugs (orange color)
Figure 2.7.1 – Pilot lamps unit
The operating principle of the pilot lamps of CLU is the following:
- pilot lamp 1 to indicate that the air filter is clogged to the max. (figure 2.7.1) lights up
when the max. permissible level of filter dirtiness is exceeded and the filter requires cleaning;
- pilot lamp 2 to indicate emergency oil pressure drop in the system of hydrostatic
power steering lights up when the oil pressure in the system of hydrostatic power steering
drops below 0,08 MPa (periodic lighting up of the lamp 2 with engine minimal speed is as-
sumed – when revolutions are increased the lamp 2 shall go out);
- pilot lamp to indicate operation of heating plugs 3 indicates heating plugs operation
(functioning algorithm of the pilot lamp indicating heating plugs operation is provided below).
