all tractor control levers shall admit fixing in the corresponding positions;
in case of accident or excessive increase of the engine crankshaft speed, immediate-
ly stop the fuel feed by pulling the engine shutdown handle (for the tractors with
YaMZ and TMS engines) or by switching off the ignition (tractors with Mercedes en-
gine);
do not permit engine operation under load at the cooling fluid temperature below
70
°С;
In case of the engine oil and cooling fluid temperature rising above the permissible
value, stop the tractor and set the minimum engine crankshaft speed; continue travel-
ing when the normal values are achieved;
in order to avoid overheating of the cooling fluid, it is necessary to see for the ab-
sence of clogging of the water radiator plates. To this end, when working in dusty
conditions, it is necessary to perform radiator blowdown every shift with compressed
air under the pressure of 5...7 kgf/cm

during every shift or (in case of contamination
not removable by purging) rinse the radiator core with water under 5…7 kg/cm
2
pres-
sure as per cl. 7.5.4.
tractor brakes shall be in good working order. When braking the tractor traveling over
dry and hard ground using the service brake, the braking distance shall not exceed
13 m at the speed of 8.33 m/s (30 km/h) and 6.5 m at the speed of 20.2 km/h. The
brake pedal being fully depressed shall not bump up against the cabin floor;
it is not allowed to drive the tractor under facilities with the driving clearance height
below 4 metres;
when turning, select the speed providing for a safe traffic.
IT IS PROHIBITED
to enter
tight turns at a gear exceeding the first gear of the fourth mode;
in the course of tractor traveling with the pressure in tyres below 170 kPa (1.7
kgf/cm
2
), the speed shall not exceed 5.56 m/s (20 km/h);
IT IS PROHIBITED
to use parking brake when moving.
IT IS PROHIBITED
to tow the tractor by suspension unit.
during motion down the slope,
IT IS PROHIBITED
to use coasting;
see for the absence of leaks of cooling fluid, oil, fuel, electrolyte; in case of a leak be-
ing detected, eliminate it;
regularly clean the tractor from dust and dirt, check the tractor configuration, reliability
of all outer fasteners;
