3.2 Tractor use
3.2.1 Boarding the tractor
The tractor is boarded through the cab left door. A foot step is provided for making tractor
boarding more convenient.
3.2.2 Engine start and preparation for it
To start the engine of tractor “BELARUS-2122.6”, do the following:
-
engage the tractor parking brake;
-
if required, fill in fuel and bleed the fuel delivery system to remove air from it;
-
set the handle for fuel feed control into the position that corresponds to the minimum fuel
supply to the engine;
-
make sure that the electronic pedal of fuel feed control is in its initial position and it is not
affected by physical influence. Do not press the fuel feed control pedal when starting the
engine;
-
set the handle for rear PTO drive activation into the position “PTO drive off”;
-
the handles for RLL control shall be in the middle position;
-
set the lever shifting GB ranges into a neutral position;
-
turn on the accumulator battery switch;
-
turn the key of the starter and instruments switch from “0” position into position “I”;
By doing this:
1) On the integrated indicator both RPTO scale range annunciators and all RPTO scale
segments turn on for not more than one second, and the needles of engine speed and rpm
indicators deviate from their initial positions (or the needles “shake” on indicator zero marks for
not more than one second) – it confirms LED annunciators and needle indicators workability.
2) All LED annunciators and indicators in CECS light up within about two seconds, a digi-
tal indicator displays figure “8”, an audible annunciator gets activated – operability of LED an-
nunciators, indicators and audible annunciator is confirmed. Then LED indicators and annun-
ciators, a digital indicator and an audible annunciator pass to the operating mode – annuncia-
tors for zero gear (gear “0”), FPTO and RPTO switching off remain on, an indicator for gear
shifting mode displays a moderate operation mode and a digital indicator indicates figure “0”.
The rest of LED annunciators and an audible annunciator get switched off.
3) All LED annunciators in ECP light up within about two seconds, an audible annunciator
gets activated – operability of LED and audible annunciators is confirmed. Then LED annun-
ciators and an audible annunciator pass to the operating mode – only one of annunciators for
activation of fuel supply electronic control pedal remains switched on (reverse or forward
travel, for the reason of reversing control station absence on “BELARUS-2122.6” these an-
nunciators have no information value), an audible annunciator gets switched off.
4) The information screen displays a company logo for several seconds – it confirms
workability of the screen. Then in case there are no failures in the EECS operation, the infor-
mation screen functions in the operating mode – it displays actually measured parameters of
the engine. If failures are detected, the information screen produces an acoustic signal, and a
brief description of the detected failures appears on the screen. The detected faults shall be
eliminated before the engine start. If the level of AdBlue reagent is lower than 28% of the tank
filling volume for SCR liquid, a corresponding symbol appears on the monitor in a flashing
mode. It is required to refill AdBlue reagent into the tank for SCR liquid before engine start.
5) A pilot lamp of emergency oil pressure in HSC lights up on the pilot lamp unit. A signal
lamp of oil emergency pressure in the engine lubrication system (and a buzzer sounds), a sig-
nal lamp of air emergency pressure in the pneumatic system (if it is below the accepted value),
a signal lamp of fuel reserve capacity in the tank (when reserve volume of fuel remains in the
tank), control lamp of additional AB charging with 24V voltage light up on the dashboard. A pi-
lot signal annunciator of the engaged parking brake turn on in a flashing mode with 1 Hz fre-
quency on the integrated indicator.
6) A pilot lamp that indicates heating plug operation lights up on the pilot lamp unit.
