Lowest temperature -14℃ or higher
-35#
Lowest temperature –29℃ or higher
-50#
Lowest temperature -44℃ or higher
NOTICE
• The diesel fuel in the tank has been drained off
basically before delivery, so customers should
add diesel fuel of appropriate grade according to
the operating ambient temperature and the
governing emission regulations.
• Do not add mixed diesel fuels of different grades.
• Light fuels may affect the fuel economy or
damage the combustion components.
• It is recommended to use the diesel fuels with
sulphur content less than 5000ppm.
• It is recommended to use the diesel fuels 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 fuel 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
fuel must be 6℃ less than the lowest operating
ambient temperature.
EXPLOSION AND FIRE HAZARD
• Do not mix the diesel fuel with
gasoline, alcohol or their
mixtures.
• Do not add diesel fuel 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. Any dirt or water entering
the combustion system can cause
severe damage to the fuel pump and
injector.
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.
2. Pull out the emergency stop button at ground
controller to ON position.
3. Turn the key switch at ground controller to ON
position.
4. Move the engine start switch and idle it 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.
8. Add engine oil as needed. Do not overfill. It is
recommended to use engine oil equivalent to or
higher than CJ-4 with viscosity grade of 15W-40.
