– The air pressure gauge in the first circuit of the pneumatic system with built-in alarm
signaling of the minimum limit value of 0.45 MPa (4.5 kgf/cm
2
)
The air pressure in the pneumatic system of brakes in the process of operation shall be equal to
0.65
–0.8 MPa (6.5–8 kgf/cm
2
).
16
– Engine hour meter / voltmeter
The instrument shows the number of engine hours during the first 3...5 s after switching on the
battery master switch.
In the course of operation the instrument reading range shall be 22.8
–30.0 V. The increase or
decrease of readings indicate afault of the generator or voltage regulator.
17
– Keylock switch of the starter and instruments
The lock has the following positions:
zero position (fixed)
– the key is inserted vertically;
first position (fixed)
– the key is turned in the clockwise direction. Power is supplied to the
generator excitation winding;
second position (non-fixed)
– with the key being turned further in the clockwise direction
power is supplied to the generator excitation winding, voltage regulator and starter drive
relay. In case of the key being released from this position, it will return to the first position;
third position (fixed)
– the key is turned in anticlockwise direction from the zero position.
This position is provided at the operation of the radio equipment on the tractor.
18
– Indicator lamp of accumulator charge
The lamps comes on when there is no charging current from the generator.
25
– Indicator lamp of oil overheating of the hydraulic system
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.
36
– 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.
