Notice
1.
Before the first use, the engine should go through a 50h trial run. For more
information, refer to the running-in requirements.
2.
After the cold start, the engine should slowly increase the speed. Don’t let the
engine run at idle speed for a long time or suddenly speed up. After running with
heavy load, do not immediately stop. It is necessary to idle for 5-10 min at low
speed.

It is prohibited to work without air filters which could prevent air from entering
the cylinder without being filtrated. The air filter should be regularly maintained
or replaced, otherwise power reduction, parts wearing and other problems would
happen.

Please select specified grades of fuel and oil and use the special and clean
containers. The fuel and oil should be filtrated with the strainer before being
added.

If the diesel engine fails to start within 15s, repeat after at least 2 min.

It is prohibited to fill the diesel engine with water rather than antifreeze, which
could greatly reduce the engine life and leads to damage of the after-treatment
system and other parts.

Before the start, please ensure the antifreeze, urea solution and oil are at the
proper levels.
8.
The strainer of urea solution tank must be cleaned regularly, otherwise the OBD
system will giving alarm.

When the vehicle is parked for a long time and the ambient temperature is lower
than the freezing point of antifreeze, it is necessary to drain the water out
through the discharge valve of the air compressor.
