- turn the key of starter and instruments switch from “0” to position “I”. This will trigger
the following:
1) on tractors with instrument board with castable panel, the tachospeedometer dis-
play will reveal the total engine operation time in hours; also, within not more than one sec-
ond, both annunciators of rear PTO scale range and all segments of rear PTO scale will turn
on, and the needle of engine rpm indicator will deflect from the initial position (alternatively,
within not more than one second, the needle will “shake” over the zero mark of the indicator)
– this confirms the workability of LED annunciators and needle indicators.
On tractors with instrument board with molded panel, within not more than one sec-
ond, both annunciators of rear PTO scale range and all segments of rear PTO scale will turn
on, and the needles of speed and engine rpm indicators will deflect from the initial position
(alternatively, within not more than one second, the needles will “shake” over the zero mark
of the indicator) – this confirms the workability of LED annunciators and needle indicators.
2) On the pilot lamps units, pilot annunciator lamp of parking brake engagement will
activate in blinking mode with the frequency of 1 Hz (on tractors with instrument board with
molded panel, pilot annunciator lamp of parking brake engagement will activate in blinking
mode with the frequency of 1 Hz on the integrated indicator); and the pilot lamp of HSC
emergency oil pressure will light up. The instrument board will light up the pilot lamp of
emergency oil pressure in the system of engine lubrication (and a buzzer will sound), the
pilot lamp of emergency air pressure in the pneumatic system (if it is below the permissible
minimum), pilot lamp of reserve volume in fuel tank (if the fuel in tanks in on reserve volume).
3) Two seconds after shifting the starter and instrument switch key from position 0
into position I, the pilot annunciator lamp of heating plugs operation will light up on the pilot
lamp unit.
- after the pilot lamp of HP operation changes from the continuous glowing mode to
the blinking mode with a frequency of ≈ 1 Hz, start the engine by depressing the clutch pedal
and turning the key of the starter and instruments switch from position I (Instruments ON)
into position II (engine start). If HP activation is not required, turn the key of the starter and
instruments switch from position “I” (instruments are turned on) to position “II” (engine start)
within less than 2 seconds. In this case, the heating plugs do not turn on and the HP pilot
lamp does not light up.
- hold the key of the starter and instruments switch until the engine starts up, but not
longer than for 15…20 seconds; if the engine has not started up, perform another start-up
not sooner than after one minute;
- after the engine has started, release the clutch pedal, check the operation of all
pilot lamps and readings of the instruments (coolant temperature, oil pressure in the engine,
battery charge, etc.). After the pilot lamp of emergency oil pressure in the engine goes out,
the buzzer will turn off. Let the engine run at 100050 rpm until the pressure stabilizes in the
operating range.
- adjust, if necessary, the position of water radiator shutter for maintaining normal tem-
perature mode.
