OPERATION UNDER SPECIAL
CONDITIONS
Operation under extreme cold conditions
If the machine is working in extremely cold weather, it is nec-
essary to adopt protective measures to guarantee the normal
operation. The following detailed inspection can ensure the ma-
chine to work normally in cold temperature.
1.
Check whether the cooling system has used proper an-
ti-freeze fluid under extreme low temperature. Carefully
check cooling system and record the leakage situations.
2.
Keep the battery fully charged to prevent from freezing. If
you add water into the battery, run the engine for at least
one hour to make it mixed with electrolytes.
3.
Keep the engine in the optimal conditions to realize the
easy start and operation in unfavorable weather.
4.
Select proper engine oil according to the temperature. For
more information see "Lubrication and specifications" in
Engine Manual.
5.
Ensure the fuel tank is fully filled with fuel at any time.
Drain out the condensates in the fuel tank before opera-
tion. Check fuel tank the filter element, drain out the con-
densates in it (e.g., wax-like substance), and ensure the
freezing point of the used oil is lower than the lowest ambi-
ent temperature.
6.
Perform the full lubrication for the machine according to
the instructions in Section 4 of "Maintenance Period Chart"
and to the lubrication diagram attached on the machine.
7.
Start the engine to make it reach the normal temperature
before working with load.
A. When the machine is in idle state, if the mud and ice
are attached on the running components, please heat
to melt the frozen substances.
B. Be careful to operate the hydraulic components until
they reach the temperature at which they can normally
work.
C. Check all machine control device and/or functions to
ensure the normal operation.
8.
Put a backup external air filter in the cab to replace the fro-
zen components in case.
9.
Perform auxiliary startup in cold weather, see Section "Start
in Cold Weather" in this Manual.
10. In order to prevent from icing, remove all mud, snow and
ice. If possible, use canvas to cover the machine, and pre-
vent the canvas edges from being frozen onto the ground.
