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-922.6", 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 mini-
mum 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 PTO drive control handle in position "PTO off";
- set the rear PTO drive switch handle in the neutral position and the rear PTO acti-
vation button in position "PTO off";
- the handles of the hydraulic system valve group control shall be in "neutral" posi-
tion, the handles for RLL control shall be in the middle position, the switch of the
rear axle DL shall be in "off" position;
- set the levers shifting GB gears and 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) The engine control system panel carries out self-check. If there are no errors in the
system operation, the fault testing annunciator on the engine control system panel shall light
up and go out - it confirms the annunciator lamp workability and its correct connection to the
tractor on-board system. If any errors are detected, the testing annunciator provides a light
code of the fault. The detected faults shall be eliminated before the engine start.
3) 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 in-
formation screen functions in the operating mode – it displays actually measured parame-
ters of the engine. If failures are detected, the information screen produces an acoustic sig-
nal, 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 moni-
tor in a flashing mode. It is required to refill AdBlue reagent into the tank for SCR liquid be-
fore engine start.
4) 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 signal 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). A pilot signal annunciator of the engaged parking brake turn on in
a flashing mode with 1 Hz frequency on the integrated indicator.
5) A pilot lamp that indicates heating plug operation lights up on the pilot lamp unit.
- after the heating plug pilot lamp goes out, start the engine, for which:
1) Depress the clutch pedal;
