Foreword
Series Yangdong multi-cylinder diesel engines are ideal power units for light vehicle,
agro motor, small tractor, air conditioner in bus, generator set, water pumps, fire-fighting
pumps and engineering machinery.
The normal and reliable operation and long service life of the engine depend not only
on the manufacturing quality, but also on the reasonable operation and correct
maintenance.
In order to provide the detailed description and instruction of this engine for operators
to manipulate it correctly in short time, we offer this manual which briefly describes the
performance of series Yangdong diesel engines to operators, maintenance workers and
relevant mangers.
Since the construction of this engine is subject to frequent improvement and
development during production and practice, it is possible that the engine supplied is
somewhere not exactly the same as one described herein. Please pay attention to that
when reading the manual.

lube oil with stipulated number according to the instruction.
2,It is strictly forbidden to leak out from an intake system (air filter, pipelines and connecting
components)
3, It is strictly forbidden to have hard water (well water or spring water)as cooling water, if necessary
to apply the hard(water),soften it first.
4, It is strictly forbidden to start under the circumstances of lack of lube oil or water
5, It is strictly forbidden to operate at overload or under other conditions against the rules
6, It is strictly forbidden to regulate the fuel injection pump at will
7, It is strictly forbidden to change the diameter of the pulley
8,To control the starting time(less than 15 seconds) and the starting interval(more than 2
minutes)strictly
9, It’s must to maintain the diesel engine technically in the allotted time
10, Ambient temperature under 0℃, discharge all the coolant to prevent frostbite after stop
