2.6 Instrument board
Instrument board 13 (figure 2.1.1) includes six gauges with five signal lamps as
shown in figure 2.6.1.
1 – gauge to indicate oil pressure in the transmission system; 2 – signal lamp of emergen-
cy air pressure in the pneumatic system; 3 – gauge to indicate air pressure in the pneu-
matic system; 4 – pilot lamp of additional accumulator battery charge (not used); 5 – volt-
age gauge; 6 – signal lamp of reserve fuel volume in the tank; 7 – gauge to indicate fuel
volume in the tank; 8 – signal lamp of emergency temperature of engine coolant; 9 –
gauge to indicate temperature of engine coolant; 10 – gauge to indicate oil pressure in the
engine lubrication system; 11 – signal lamp of emergency oil pressure in the engine lubri-
cation system;

2.6.1 The gauge of oil pressure in the transmission hydraulic system 1 (figure 2.6.1) indi-
cates oil pressure in the hydraulic system of friction clutches control in tractor transmis-
sion.
The scale of oil pressure gauge has three zones:
- operating — from 800 to 1500 kP
а
green color);
- emergency (two) — from 0 to 800 kPa and from 1500 to 1800 kPa (red color).
Normal operating oil pressure in the hydraulic system of the transmission is from 900 to
1100 kPa.
2.6.2 The scale of the gauge of oil pressure in the pneumatic system has three zones:
- operating – from 500 to 800 kPa (green color);
- emergency (two) — from 0 to 500 kPa and from 800 to 1000 kPa (red color).
Signal lamp 2 (red color) is built in the gauge scale which lights up when the pressure in
the pneumatic system drops below 500 kPa.
2.6.3 Voltage gauge 5 (figure 2.6.1) indicates accumulator batteries voltage with the
engine stopped when the key of starter and instruments switch (figure 2.2.2) is set in posi-
tion “I”. With the engine running the voltage gauge indicates voltage on generator termi-
nals.
