NOTICE
• The diesel has been drained off basically before
delivery, 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.
• Light fuels 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 at operating temperatures
below 0℃ and min. cetane number of 40 at
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
mixtures.
• Do not add diesel when the
engine is running.
DAMAGED MACHINE HAZARD
Due to the extremely accurate tolerance
match of the diesel injection system, it is
critical to keep the fuel clean and free of
dirt or water. The dirt or water entering
the combustion system can cause
severe damage to the fuel pump and
injectors.
INSPECTING ENGINE OIL
LEVEL
NOTICE
Turn off the engine before inspection.
An appropriate engine oil level is vital to maintaining the
engine performance and extending its service life,
otherwise the engine parts will be damaged. Through
daily check, the inspector can know about the changes
in engine oil level which may indicate a system distress
with the engine.
1. Turn the ground/platform select switch to ground
control position.
2. Pull out the emergency stop button at ground
controller to ON position.
3. Turn the FE/DC mode select switch at ground
controller to FE mode position.
4. Flip the engine start switch and idle the engine for 2
minutes.
5. Switch off the engine, and 5 minutes later open the
turntable cover on the right side.
6. Remove the engine dipstick to inspect the engine
oil level.
7. The engine oil level should be within the FULL and
ADD marks.
