Section A. Safety precautions
Belarus – 90/92 – Operating manual
13
• Keep tractor and its equipment,
especially brakes and steering
equipment, in operable condition for the
safety of your own and people around.
• Do not make any alterations to the
tractor or its individual components
without approval of your dealer and
manufacturing works.
Safety requirements in operating
and maintaining electrical
equipment
• To avoid damage of semiconductor
devices and resistors take the following
precautions:
- do not disconnect SB terminals with
running engine. This will result in peak
voltage in the charge circuit and
inevitable damage of diodes and
transistors;
- do not disconnect electrical wiring
until the engine is shut down and all
electrical switches are off;
- do not cause short-circuit due to
wrong wiring connection. Short-
circuiting or wrong polarity will cause
damage of diodes and transistors;
- do not connect SB to the electrical
equipment system until polarity of
terminals and voltage is checked;
- do not check electric current ‘by spark”,
as this will immediately lead to
transistors’ break-down.
Hygiene requirements:
• During continuos work during the shift
for over 2.5 hours, it is necessary to use
individual noise protection means under
GOST 12.4.051-87 (earplugs,
earphones)
Fire safety requirements
• Tractor has to be equipped with
firefighting equipment – a shovel and
fire extinguisher. It is prohibited to
operate the tractor without firefighting
equipment.
• Sites of tractors’ parking and storage
of fuels and lubricants must be plowed
around for a 3m width at least and
equipped with fire fighting means.
• Do not allow staining of collector and
muffler with dust, fuel, straw, etc.
• Do not allow winding of straw on
rotating parts of machines ganged up
with tractor.
• When washing parts and assembly
units with kerosene and gasoline, take
measures to prevent inflammation of
washing liquid vapors.
• Do not allow tractor operation in fire
hazardous place places with hood and
other protective devices being taken off
the heated engine parts.
• Do not use open flame for heating oil
in the engine pan and burning stains in
the radiator core.
• When flame source appears, cover it
with sand, canvas cloth, sacking or some
other tight cloth. Use carbon-dioxide fire
extinguisher. Do not pour water on
burning fuel.
• Avoid highly inflammable materials
close by outlet manifold and muffler
when the engine is running.
• When harvesting hay or straw,
working in the places with enhanced fire
hazard, use at the exhaust system
the
spark blowouts completed with muffler
or separately.
