4.4 Tractor run-in

4.4.1 Technical maintenance before tractor run-in

Before placing a new tractor in operation do the following:
- wash the tractor, remove preservative lubricant (if any on the tractor);
- carefully inspect the tractor, check it for completeness and availability of instruction
manuals;
- remove accumulator batteries, set them into working condition and mount back;
- check threaded jounts for tightness and tighten if necessary;
- check oil level in the engine oil sump, in the transmission, in FDA case, in cases of
FDA wheel-hub drives and, if necessary, add as per section 6 "Technical maintenance";
- drain the available fuel out of the fuel tank and fill the fuel tank with new settled
fuel: in winter – winter grade, in summer – summer grade;
- check the level of braking fluid in tanks of main cylinders of hydrostatic drives of
clutch and working brakes and if necessary add as per section 6 "Technical maintenance";
- check the level of braking fluid in the compensation chamber of the clutch main
cylinder and of the brake main cylinder on the reverse of clutch and brake control and, if
necessary, add as per section 6 "Technical maintenance";
- fill the engine cooling system with cooling fluid to the beginning of a damping cage
of the extension tank;
- check and, if necessary, set a desired pressure in tyres according to table 4.3;
- make sure there are protective guard shields (for RPTO, FPTO, etc.);
- carry out operations in shift-time technical maintenance of the engine, listed in the
engine operation manual;
- check engine running, operability of lighting and warning devices, action of brakes
and steering control, and also check functioning of the other systems and units of the trac-
tor over control and measuring instruments;
Before starting to run in, check tightness of nuts attaching rear wheels to the hub
and also nuts attaching front wheels to FDA drive flanges. The tightening torque shall
make 700 to 750 N·m.
4.4.2 Tractor run-in
ATTENTION: FIRST 30 HOURS OF TRACTOR OPERATION HAVE GREAT IN-
FLUENCE ON OPERATIONAL PARAMETERS AND LIFE SPAN OF THE TRACTOR.
YOUR TRACTOR WILL FUNCTION PROPERLY FOR A LONG TIME PROVIDING YOU
CARRY OUT THE RUN-IN CORRECTLY AND PERFORM OPERATIONS IN TECHNICAL
MAINTENANCE IN TERMS SPECIFIED IN SECTION 6 "TECHNICAL MAINTENANCE"!
ATTENTION: IT IS OBLIGATARY THAT YOU CARRY OUT TRACTOR RUN-IN
FOR 30 HOURS! LOAD THE TRACTOR UP TO 80 % OF ITS RATED POWER BEFORE
THE FIRST TECHNICAL MAINTENANCE (TM-1) (125 HOURS)!
Carrying out the 30-hour run-in follow the below instruction:
- constantly inspect instrument indications, operation of lubrication system, cooling
system and power supply system. Control levels of oil and fluids in refill capacities;
- check outer fastening links for tightness and tighten them;
- do not overload the engine, avoid engine smoking and speed decrease. The fea-
tures of overload are sharp decrease of speed, smoking and absence of engine reaction to
increase of fuel feed. Operation at high gear under load results in excessive wear of fric-
tion parts of the engine;
- tractor operation at lower gear under small load and with increased speed of the
engine will result in fuel overconsumption. Right selection of the gear for each specific
condition of operation ensures fuel economy and reduces engine wear-out;
- avoid prolonged engine operation without load in a mode of max. or min. speed of
the engine;
