OPERATION NOTE
Using the improper type lubricating oil will burn out the inner part of the
engine, even cause the engine to wear rapidly. And the service life of the
engine will be also shortened.
3.1.3 Cooling water
Be sure to adopt tap water as cooling water.
[
]
OPERATION NOTE
Be sure to add anti-rusting or anti-freeze solution to the cooling water.
Add anti-freezing solution to the cooling water in winter, otherwise, the
frozen water may damage the cooling water system.
A. Anti-rusting solution:
Be sure to use the superior quality anti-rusting solution. But do not use it in winter
because it may freeze when the air temperature is low. Its standard mixing ratio is
6%.
B. Anti-freezing solution:
Be sure to use the superior quality anti-freezing solution. However, it's not
necessary to use it with anti-rusting solution simultaneously. This kind of solution
can be added to cooling water in all seasons. Its mixing ratio is 30%~55%.

OPERATION NOTE
If the mixing ratio of anti-freezing solution is too low, cooling water will
freeze in low temperature, which causes damage or rust to the water pipe.
If the mixing ratio of it is too high, the engine performance will be
decreased.

Use the commercial available anti-freezing solution with the mixing ratio
recommended by manufacturer, meanwhile, it must be replaced every year.
8.2 The adjustment of the injection timing
In order to obtain the most economical fuel consumption ratio and better running
performance, the injecting ahead angle should be set properly. The adjustment
method of KM376QC/ KM376ZQC ahead angle should be as followed:
(1) Crank the crankshaft to make crankshaft lies on the 30 spot NO.1 cylinder (In
other word, it's the injection pump bolt fan mark)
(2) Loosen the mounting nuts in the fuel injection pump and the bolts in the
supporting plate of the fuel injector rear end until the fuel injection pump can
revolve. Then keep the fuel injection pump toward the inner surface to the bottom.
(3) Install the lever-type micrometer calipers in the front end of the fuel injection
pump, and let the pointer needle point at naught.
(4) Crank the crankcase to make NO.1 cylinder of the engine stay at upper dead
center of the compression stroke.
(5) Turn the injection pump toward outside surface slowly until the reading of the
meter is 0.97
0.03mm.
(6) Check the meter again. (Crank the crankcase to position 1, watch the reading
of meter whether reset to naught position. Then crank the crankcase until it
reaches the upper dead center, check the meter reading whether is 0.97
0.03mm. If the reading is right, the adjustment is completed. If the reading isn't
right, repeat the above adjusting steps.)
(7) Tighten loosened nuts and bolts above mentioned.
