z
Never
let impurities enter when changing and adding fuel.
z
Strictly choose the fuel brand according to this manual.
z
The fuel may be frozen at low temperatures (particularly temperatures lower than -15 ). So it is
℃
necessary to change the kind of fuel according to the ambient temperature.
z
Always
fill the fuel tank full after operating to prevent the water, which is condensed by the
moisture in the air, from entering the fuel tank.
z
If the engine fails to suck fuel or the filters have been just replaced, drain out the air in the circuit.
2.1.2 Coolant
z
Use clean and soft water, rain or tap water as coolant. Well water and spring water can be used as
coolant after soft processing and precipitation to avoid causing scale which can influence the
performance of dispelling the heat.
z
If the engine overheats, add coolant until the engine cools down completely.
z
Add coolant to specified level. If the level is too low, it will cause the overheating of the engine
system and the corrosion of the cooling system.
z
Add antifreeze to coolant if ambient temperature is lower than 0 . Drain the coolant out after
℃
working (please refer to
CHAPTER III 3.5.3 Operation in Cold Weather
and refill oil
before next working if there is no antifreeze in the coolant.
z
Antifreeze is flammable. Keep fire away when adding the antifreeze.
z
Never
use 100% antifreeze as coolant. Refer to the following table to select the mixing
proportion.

2.1.3 Lubricant
z
Lubricant is used to reduce noise and prevent wear on the joint surfaces.
z
Joints not included in the manual (connectors, jointing sleeves) are treated during overhaul. So
they do not need be lubricated. When some parts become inflexible because of long-term
operation, it is necessary to add lubricant.
