Instrument Cluster
The device incorporates six indicators (5,
6, 7, 8, 9, 10) together with the signal
lamps (6a, 7a, 8a, 9a, 10a).
GB Oil Pressure Gauge (5)
The gauge scale has three zones:
– operating: from 800 to 1500 kPa
(8…15 kgf/cm
2
);
– non-operating (2 off): from 400 to 800
kPa (4…8 kgf/cm
2
) and from 1500 to
1800 kPa (15…18 kgf/cm
2
).
Pneumatic System Air Pressure
Gauge (6)
The gauge scale has three zones:
– operating: from 500 to 800 kPa (5…8
kgf/cm
2
);
– non-operating (2 off): from 0 to 500
kPa (0…5 kgf/cm
2
) and from 800 to
1000 kPa (8…10 kgf/cm
2
).
The gauge scale is provided with a red
pilot lamp (6 а) which lights up when the
pressure in the pneumatic system drops
below 500 kPa (5 kgf/cm
2
).
Fuel-Level Gauge (7)
with an amber
reserve fuel lamp (7а). The gauge scale
has the following marks: “0 – 1/4 – 1/2 –
3/4 – 1”.
Voltage indicator (8)
The device indicates SB voltage on a
shut down engine, when the starter
key (2) is in position “I”. When the engine
is running, the indicator shows the volt-
age at the alternator terminals. A red pi-
lot lamp (8a) is built into the voltage in-
dicator (8). It lights up, if no charging of
an auxiliary storage battery occurs.
IMPORTANT! If the voltage indicator
(8) shows no charging of the storage
batteries, check the condition and
tension of the alternator driving belt.
The voltage indicator scale has the fol-
lowing zones:
