4.4 Precautions for running in cold environments

Fuel: Choose a grade of diesel fuel depending on the environmental temperature.

Lubricating oil: Choose lubricating oil of different viscosities depending on the seasons.

Coolant: Add antifreeze additive into the cooling system and choose the coolant of differ-
ent grades depending on the ambient temperature.

Start: The auxiliary starter can be adopted if necessary in winter. After starting the engine,
only operate the engine with load when the oil pressure and water temperature are nor-
mal.

Before the cold season begins, be sure to check the electrolyte liquid level, viscosity and
battery voltage. If the engine is not going to be operated for a long time and under very
low temperatures, the battery should be removed and stored in a warmer room.

Shut-down of the engine: When shutting down the engine in a cold climate, unload the
engine first and then run the engine at idling speed for 1 to 2 minutes. And then stop the
engine after the water and oil temperatures decrease. The coolant with antifreeze addi-
tives should not be drained out after shutdown. Otherwise, open the drain valve or plug on
the engine body, oil cooler cover, and radiator and water inlet pipe to drain the coolant
completely to prevent the engine from being frost cracked.
