PREPARATION FOR DAILY START-UP
1. Make sure there is enough fuel in the tank.
2. Check the oil level in the engine sump; if necessary pour
fresh oil up to the top level mark.
3. Check for the coolant level in the cooling system.
4. Fill the engine fuel supply system with fuel by means of a
hand fuel pump.
5. By visual examination check for leakage the pipelines and
components of the lubrication, fuel supply and cooling systems.
Engine cold start without air preheating depends on the type of
the engine oil used (See Operational Substances Section). At ambient
temperature up to 10º
С below zero the engine operating on the
specified oils, with the starter fed by the battery having overall
capacity of not less than 190 Ah, with the clutch pedal fully depressed
must be easily started-up without using starting aids.
With SAE 15W-40 and SAE 15W-30 oils the engine can be
started-up at ambient temperature up to –20

С and higher; with SAE
10W-40 and SAE 10W-30 oils – up to –25

С and higher; with SAE
5W-30 oils — up to –30

С and higher, with electric heating provided
by the four glow plugs installed at the intake manifold entrance.
At ambient temperatures lower than above-mentioned, it is
necessary to warm up the engine by an engine start heating device in
accordance with the vehicle operation manual.
