This machine uses diesel oil as the fuel, and the diesel
oil filled in the factory is generally 0# diesel, which is
suitable for use in areas with ambient temperature
above 4℃ (39.2℉). The diesel oil has been basically
emptied when the machine leaves the factory, and the
user needs to fill diesel oil with appropriate grade ac-
cording to the ambient temperature and emission regu-
lations. The following table shows the recommended
ambient temperature for different grades of diesel oil:

NOTICE
Please go to a certified gas station to purchase
qualified fuel oil. It is recommended prepare an oil
storage tank with fuel filter and store the fuel oil in the
tank for more than two days to precipitate impurities
and water before use.
Engine Oil
The engine oil filled in the factory is generally 15W-40
oil of CJ-4 grade, which is suitable for use in areas with
temperature range of -15℃ ～40℃ (5～104℉). If the
ambient temperature is beyond the applicable range,
please select other appropriate engine oil.
The ambient temperature varies from region to region,
please choose the oil viscosity grade that suits your re-
gion according to the recommendations in the table
below.

Coolant
The coolant filled in the factory is generally -18℃ pre-
mixed coolant, which is suitable for use in areas with
ambient temperature above -18℃ (-0.4℉). If the ambi-
ent temperature is beyond the applicable range, select
other appropriate coolants.
The environment temperature varies from region to re-
gion, so please choose the coolant applicable to your re-
gion according to the recommendations in the table
below.
