WARNING
1. Failure-free functioning of the engine and its long operating life
depend directly on their correct handling. Therefore carefully read this manual
before starting the operation.
2. During the engine break-in period its mating parts become
aligned, therefore further working efficiency largely depends on how strictly
the rules specified in the NEW ENGINE BREAK-IN section have been
followed.
3. It is forbidden to use fuels, lubricants or coolants which are not
specified in this Manual.
4. After start-up the engine must be warmed up to the operating
temperature of 80-100oСunder load. Do not warm up the engine by letting it
run at minimum idle speed for a long time. As soon as the engine starts
reacting to a change in the fuel supply and the break system operating
pressure becomes normal, gradually increase the rpm up to the average
operating value and start moving the vehicle in low-range gears. Running the
engine at full load before it is warmed up to the operating temperature must
be avoided.
5. Do not increase the engine speed abruptly immediately after the
cold start because cold oil reaches the crankshaft and the turbocharger
bearings quite slowly which may cause the engine failure. Do not run the
engine idle for a long time during warm-up or vehicle stops.
6. The coolant temperature at the working engine outlet must range
from 80°C to 100ºC. A short-time (up to 10 min.) increase in the coolant
temperature up to 105ºC is acceptable.
7. When operating the engine, follow the readings of the instruments
and take measures as described in “Checking Engine Operation” section of
this Manual.
8. To avoid the turbocharger failure, the engine must work for 2-3
minutes at medium idle before stopping.
9. To avoid failure, it is strictly forbidden to activate the starter
on the running or still running engine.
10. When operating the engine, observe the data shown on display.
11. Technical maintenance of the engine must be performed in
accordance with the TECHNICAL MAINTENANCE section.
