3.2 Preparation before starting
3.2.1 Add the lubricating oil
(1) The amount of the lubricating oil added should flush with height of the
lubricating oil level in the oil sump. Put the engine on a level surface at first, then
check the oil level.
(2) The lubricating oil level in the oil sump should between the lower and upper
marked line of the oil stick.

OPERATION NOTE
The lubricating oil level in the oil sump should between the lower and
upper marked line of the oil stick. If the lubricating oil is not enough, it will
damage the engine easily. However, if excessive, the lubricating oil will spill
over from the air opening hole.
3.2.2 Refill the fuel tank
(1) Add the fuel to the fuel tank.
Add the fuel without containing dirt and water. To prevent the fuel from overfilling
during the running course, the amount of the refilled fuel should be 90% of the fuel
tank capacity.
DANGER
Make certain whether the type of the fuel refilled is right or not. If improper
fuel is added, it will cause the fire. If the fuel is overfilled, wipe it up at once.
(2) Eliminate the air in the fuel system
When refill the fuel at first time or refuel the tank normally as required, you should
eliminate the air in the fuel line which begins from the fuel tank, though water-oil
separator or fuel filter or primary oil delivery pump, to the fuel injection pump.
If the air mixes with the fuel in the fuel line, the fuel injection pump won't provide
the high-pressure fuel for the fuel injector, and the engine can't start also.
This product adopts the VE distributor pump, and the lubricating and cooling of the
VE distributor pump relies on the fuel. So if the fuel is cut off, it will result in
damage of VE distributor pump.
8. THE ADJUSTMENT OF THE TECHNICAL DATA
KM376 series engines are different from the general-use diesels in the structure.
In order to ensure maintenance quality, please read this additional section
carefully.
8.1 The adjustment of valve clearance
The valve clearance refers to the cam surface the clearance of inlet valve should
be 0.25 mm in cold condition, and that of the exhaust valve should be 0.30 mm. In
hot condition, the clearance of inlet valve should be 0.30 mm, and that of the
exhaust valve should be 0.35mm. If the clearance is improper, make it reach to
the standard by adjusting the shim thickness.
8.1.1 The measurement of the clearance
Measure the clearance using the ruler as shown in the figure 8-1
(1) Measure the clearance in cold condition.
(2) The rabbet in the cam should be toward up.
8.1.2 The selection of the adjusting shim clearance
T = T +(A'-A)
2
1
T the thickness of the shim replaced
2:
T the thickness of the shim measured
1:
A': the metrical value A: the standard value
8.1.3 The replacement of the adjusting shim
Press the valve tappet down using the special tools, and get out the shim used for
the measurement, then replace the shims that need to install to primary position.
