VISCOSITY RECOMMENDED AMBIENT TEMP
0W-30 -35℃~0℃
5W-40 -25℃~30℃
15W-40 -15℃~40℃
20W-50 0℃~50℃
NOTICE
• The engine oil filled by the factory is generally
CH-4 with viscosity 15W-40, suitable for regions
with ambient temperature range of 15℃~40℃. If
the operating ambient temperature is outside of
the range, please change the engine oil as
appropriate.
• The muti-grade engine oil can provide excellent
lubrication under high-temperature operating
condition, reduce the sediments, and improve the
engine low-temperature start performance and
durability.Also, the multi-grade engine oil plays an
important role in fullfilling the machine with the
emission standards.
• Do not mix the engine oils of different grades.
• It is recommended that the sulphated ash content
not exceed 1%, otherwise it will damage the air
valve or piston, and lead to excessive
consumption of engine oil.
• The use of high-quality engine oil in conjunction
with suitable oil filter and change interval is very
critical to maintaining engine performance and
extending service life. If the oil or oil filter is not
changed as recommended, there will be
sediments, contaminants or wear incurred which
will shorten the engine service life.
INSPECTING FUEL LEVEL
NOTICE
Make sure to shut down the engine before
inspection.
Keeping the diesel fuel at an appropriate level is vital to
maintaining the engine performance and extending
service life. An inappropriate fuel level will bring
damage to the engine parts and lead to improper
functioning of the machine.
1. Open the rear right door of chassis, and locate the
fuel tank.
2. Inspect the fuel level to ensure it is within the
marking range of sight gauge.
Figure 5-2
3. If the fuel level is below the MIN position, add fuel
before resuming work.
4. Ensure the fuel tank body and ports are free of
leakage.
5. The engine must be off when adding fuel.
6. Open the cap of fuel tank, add fuel as needed.
Never overfill the tank, it is recommended to add to
50%–100% of the tank capacity.
