NOTICE
• The diesel has been drained off before delievery,
so the customer should add diesel of appropriate
grade to suit the operating ambient temperature
and the governing emission regulations.
• Do not add mixed diesel of different grades.
• The light fuel may affect the fuel economy or
damage the combustion components.
• It is recommended to use the diesel with sulphur
content less than 5000ppm.
• It is recommended to use the diesel with min.
cetane number of 45 in operating temperatures
below 0℃ and min.cetane number of 40 in
operating temperatures over 0℃. When the
cetane number of the diesel in use is less than the
recommended number,it may lead to startup
failure, instable running or large amount of white
smoke.
• The max cloud point and pour point of the diesel
must be 6℃ less than the lowest operating
ambient temperature.
EXPLOSION ADN FIRE HAZARD
• Do not mix the diesel with
gasoline, alcohol or their mixture.
• Do not add diesel when the
engine is running.
DAMAGED MACHINE HAZARD

tolerance match of the diesel
injection system, it is critical to keep
the fuel clean and free of dirts or
water. The dirts or water entering the
combustion system can cause
severe damage to the fuel pump and
injectors.
