NOTICE TO OPERATOR!
Before proceeding to work on your tractor please thoroughly read this instruction and
operating manual for the engine installed on your tractor. Strictly follow the operation
and maintenance guidelines.
IT IS PROHIBITED to work on the tractor without fire-extinguishing means. The tractor shall be
equipped with fight-fighting inventory including a fire-extinguisher and a shovel.
IT IS PROHIBITED to work on the tractor with faulty devices.
IT IS PROHIBITED to use parking brake during motion.
IT IS PROHIBITED to tow the tractor by the mounted equipment.
IT IS PROHIBITED to fill the engine cooling system and heating system with water.
IT IS ABSOLUTELY PROHIBITED to switch on the heater without cooling fluid.
IT IS PROHIBITED to openplugs of the tank filler and expansion tank or unscrew the steam-air
valve at the cooling fluid temperature over 70°С.
IT IS PROHIBITED to work on the tractor with faulty steering control, brake system, electrical
lighting and alarm signaling.
IT IS PROHIBITED to use fuses, which are not conformant by the nominal value to the electrical
diagram value.
IT IS PROHIBITED to use coasting during motion down the slope.
IT IS PROHIBITED to be under the tractor when the engine is operating.
IT IS PROHIBITED to work on the tractor at the voltage being above the voltage regulator level
set in accordance with the ambient temperature in order to avoid an explosion of storage
batteries.
IT IS PROHIBITED to operate the engine with unpressurised air feed channels from the air
cleaner to the engine and dust suction from the air cleaner.
IT IS ABSOLUTELY PROHIBITED to work with clogged or ice-covered net of the air intake pipe
cover and without free discharge of gases from the exhaust pipe.

REMINDER FOR OPERATOR
Before proceeding to work on the tractor
please thoroughly read the operating
instruction for the tractor paying special
attention to the “Safety requirements”
section.
To ensure safe work on the tractor, at first
get familiarized with the requirements set
forth in this section and further strictly fulfil
them, especially the following:
During turns select the speed providing
safe traffic. IT IS PROHIBITED to make a
sharp turn at the gear being higher than the
first gear of the fourth mode.
When working on slopes exercise caution,
carefulness in tractor driving and meet the
following conditions:
–do not shut off the engine and do not
change gears modes on steep ascents and
descents;
–when overcoming an ascent requiring
actuation of both axles, perform actuation of
the rear axle beforehand;
–during motion down the slope IT IS
PROHIBITED to use coasting;
–it is allowed to work across the slope (the
slope angle shall not exceed 5°) only with
the “slow”position of the mode change lever
and avoid sharp turns and passing
obstacles.
In crossing dams, dikes and bridges, make
sure of the possibility of driving and use only
low gears.
Crossing trenches, hillocks and other
obstacles with mounted implements should
be performed at the right angle at a low gear
avoiding sharp jogs and large rolls of the
tractor.
The motion of tractor train at maximum
speed (27 km/h) is allowed only on roads
with dry hard pavement.
When using the tractor for hauling
operations on snowy, overmoistened and
other roads with a low adhesion coefficient
as well as on slopes, turns, hillsides, during
glaze ice, etc., perform motion at low gears,
do not admit sharp braking and turns.
When moving on slipperyroads it is
recommended to drive the tractor train
“stretched out”–to this end, brake the
hooked-up vehicle first by means of a hand
brake valve and then use the tractor brakes.
During motion IT IS PROHIBITED to use
the parking brake and during hauling
operations use the hand fuel feed lever.
The travelling speed of the tractor with
mounted implementsshall not exceed 15
km/h in motion over an even road and 10
km/h in motion over a bumpy road or off-
road.
In tractor motion with the pressure in tyres
below 1.7 kgf/cm2, the speed shall not
exceed 20 km/h.
