Perform engine start-up at negative ambient temperatures according to the guidelines set forth
in Item 4.12.
After engine start-up, before taking off:
a) give the engine operate during4 min, gradually increasing the crankshaft rotational
speed;
b)
IT IS PROHIBITED
to load the engine for full power at the cooling fluid temperature
below 70°С;
c) make sure of normal operation of the hydraulic system for control over turns and
brakes;
d) if it is supposed to operate the hydraulic system for control over mounted implements,
then prepare it for operation. To this end, run the system during 3
–4 min gradually
increasing the crankshaft rotational speed, then perform several switching-on operations
for “Lifting” and “Forced lowering” and make sure of normal operation of the system.
In order to decrease the rotational speed when the engine is in operation, open the air bleeding
valve and, after air pressure drop to the nominal value (the pressure regulator has been
warmed up with passing air flow), close the valve.
Maintain the storage batteries in the charged state avoiding their discharge more than by 25%.
Remove the storage batteries from the tractor in the following cases:
a) at the ambient temperature of minus 25
–30°С with an interruption in operation for more
than 24 hours;
b) at the ambient temperature below minus 30°С with an interruption in operation for 10
hours. Perform storage of batteries according to the operating instruction (
“Lead starting
storage batteries
”).
Protect the storage batteries taken off from the ingress of dirt and metal things onto terminals
and electrical connection areas.
In order to prevent the engine overrun
IT IS ABSOLUTELY PROHIBITED
to pour hot water
over the high-pressure fuel pump before the start-up. In the process of the whole period of
operation
IT IS PROHIBITED
to wash the fuel pump with water under pressure.
At the end of working shift drain the sludge from fuel filters and fuel tank as well as condensate
from air cylinders; fully fill the fuel tank with fuel. The engine shutdown handle shall be
advanced.
To provide trouble-free operation of the tractor braking system at negative ambient
temperatures, open the disconnecting valves of connecting head after completion of work and
bleed air in order to remove condensate from the system.
