6.7 WINTER OPERATION FEATURES
It is recommended to combine the preparation for winter operation and the execution of M-
AW (autumn-winter) with regular M-2 or M-3.
In order to ensure trouble-free operation of the tractor in winter season, timely replace the
summer oil and fuel grades with winter ones according to the lubrication table and appendix
6 (“Filling tanks”). Preliminarily wash up the fuel tank.
To maintain tractor systems in good working order during a long-term outage of tractors in
the autumn-winter period, upon expiry of 2 or 3 weeks of tractor outage it is recommended to
check tractor system functioning in travel within 60 minutes at all GB modes and gears in se-
quence.
Start up the engine at negative ambient temperatures as per guidelines set forth in Item 4.12.
After engine start-up, before taking off:
a) let the engine operate for 4 min, gradually increasing the crankshaft rotation rate;
b)
IT IS PROHIBITED
to load the engine for full power at the cooling fluid tempera-
ture 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 linkage control, then prepare it
for operation. To this end, run the system for 3-4 min, gradually increasing the crank-
shaft rotation rate, then perform several system activations for LIFTING and FORCED
LOWERING and make sure of normal operation of the system.
Maintain storage batteries in the charged state avoiding their discharge by more than 25%.
Remove 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
