Safety requirements during
operation and maintenance of
electrical equipment
44. To avoid damaging the semicon-
ductor devices and resistors,
comply with the following precau-
tions:
• Do not disconnect the storage bat-
tery while the engine is running.
This will cause a peak voltage in
charging circuit and lead to imme-
diate damage to the diodes and
transistors;
• Do not disconnect electric wires
until the engine is stopped and
electric switches are in the “OFF”
position;
• Do not cause a short circuit by the
wrong connection of electrical
wires. A short circuit or reverse
polarity will cause damage to the
diodes and transistors;
• Do not connect a storage battery
into the electrical equipment sys-
tem until it has been checked for
correct voltage and terminals po-
larity;
• Do not check for current flow by
means of spark test as it will im-
mediately result in transistors
breakdown;
• It is prohibited to switch off the
battery disconnect switch when
the engine is running;
• It is prohibited to operate the trac-
tor without storage battery.
Hygienic requirements
• Daily fill the thermos with fresh
clean drinking water;
• First-aid kit should be completed
with bandages, iodine tincture, ammo-
nia spirit, borated petrolatum, sodium
carbonate, menthol valerate and anal-
gin;
• Use cab natural ventilation or cab
air heating and cooling unit according to
operation conditions.
• If the time of continuous tractor op-
eration during a work shift exceeds 2,5
hours it’s necessary to use personal
noise protection equipment according
to GOST 12.4.051-87 (earplugs, anti-
phons).
Fire safety requirements
1. The tractor should be equipped with
firefighting equipment – shovel and
fire-extinguisher. It’s prohibited to
operate the tractor without fire-
extinguishing means.
2. Never refuel the tractor when the en-
gine is running.
3. Do not smoke while refueling the
tractor.
4. Never fill the tank fully. Leave place
for fuel expansion.
5. Never add petrol or mixtures to the
diesel fuel. Such combinations may
enhance the fire or explosion hazard.
6. Places of tractors parking, storage of
fuel and lubrication materials should
be plowed around with a strip having
at least 3 m width and provided with
fire-extinguishing means.
7. Refuel the tractors with fuel and lu-
brication materials by mechanized
method with the engine shut down.
Use lighting at night. It is not recom-
mended to fill in fuel tanks with the
help of buckets.
8. When performing repair operations in
the field with the application of elec-
tro-gas welding clean parts and as-
sembly units from plant remains.
9. Prevent collector and muffler pollu-
tion with the dust, fuel, straw, etc.
10. Prevent straw reeling on the rotat-
ing parts of machines aggregated
with the tractor.
11. When washing parts and assembly
units with kerosene or gasoline take
