• As soon as the glow plug pilot lamp
starts flashing, turn the starter switch
key into “II” position. As this takes
place, an engine start pilot lamp lights
up (amber). Should the starter fail to
start with the key turned into “II” posi-
tion, and the pilot lamp is running in a
flashing mode at low frequency (about
1.5 Hz), it means that the GB handle
is not in the neutral position or, possi-
bly, the engine start interlock circuit is
open. Blinking of the pilot lamp at
higher frequency (about 3 Hz) signals
about a fault in the phase winding of
the alternator (“W” terminal).
Hold the key in the II position until the
engine starts, but no longer than for 15 s.
If the engine fails to start, repeat the pro-
cedure after not less than 30…40 s. If
the engine would not start after three at-
tempts of starting, then locate and elimi-
nate the trouble.
• With the engine running, check all the
pilot lamps for proper operation and
instrument readings (coolant tempera-
ture, oil pressure in the engine and the
GB, storage batteries charging, etc.).
Let the engine run at 1000 rpm until
the pressure is stabilized within the
operating range.
IMPORTANT! Your tractor is equipped
with a turbocharged engine. The op-
eration of the turbocharger at high ro-
tational speed requires reliable lubrica-
tion when starting the engine. When
starting the engine for the first time or
after a long-term storage, resort to
cranking the shaft by the starter for
about 10 s with the fuel feed shut off to
ensure the lubrication of the turbo-
charger bearings. Let the engine run
idling for 2…3 min before putting it un-
der load.
Starting the Engine at Low Tempera-
tures (+4° С or below)
IMPORTANT! To avoid any damage in
the power train, never push or pull the
tractor to start the engine by towing.
• Turn the starter switch key to its “I”
position (i.e., the glow plugs). As this
takes place, the pilot lamp on the pilot
lamp block lights up to signal that the
glow plugs are ON.
• Hold the key in this position. When the
lamp starts flickering, the engine is
ready for starting up;
• Turn the starter key to its “II” position
and follow the above instructions for
the engine start procedure under
normal conditions. On starting the
engine, the pilot lamp goes out and
the audible signalling turns off.
To start the engine at ambient tempera-
tures below minus 20 ° C, it is a good
practice to use a special circulatory
heater for coolant in conjunction with
starting the preheating means.
The installation of the circulatory heater
is shown in the figure.
NOTE: The circulatory heater of cool-
ant should only be used for cooling cir-
cuits filled up with antifreeze.
At settled low temperatures, use winter-
grade oils (if no winter-grade motor oil is
available, the use of a mixture of summer
