2. If no permanent anti-freezing fluid is used, be sure to fully drain the water in the
cooling system, clean up the cooling system, and then fill the new coolant.

If the loader is working in extremely cold weather, protective measures shall be taken to
ensure the normal operation. The following detailed inspection can ensure the normal
operation of the loader
at
low temperature.
1. Inspect whether correct anti-freezing agent has been added into the cooling system.
Carefully inspect the cooling system, and record the leakage.
2. Keep the battery fully charged so as to prevent
it
from getting frozen. If water is filled
into the battery, be sure to make the engine run for
at
least one hour, so as to realize
the full mixing between water and electrolyte.
3. Maintain the engine
at
the best state, so as to ensure that
it
can be started up easily
under adverse weather conditions.
4. Select the engine oil of appropriate specification on the basis of the temperature.
5.
It
shall be ensured that the fuel tank is always filled with fuel. Before operating the
loader, discharge condensate from the fuel tank. Maintain and repair the fuel tank filter
element, discharge the wax-like condensate, and ensure that the cloud point o f the
fuel used is lower than the lowest ambient temperature.
6. In accordance with the “ Table of Maintenance Interval ” as given in this Manual and the
lubrication figure printed on the loader, fully lubricate the loader.
7. Start up the engine, and make
it
reach the normal operating temperature before the
commencement of any loaded work.
1) When the engine is running
at
idle speed, if
it
is found that there is mud or ice on
any moving part, be sure to thaw such mud or ice with heat before the loader is
operated.
2) Carefully operate the hydraulic part, until the normal operating temperature is
reached.
3) Inspect all control devices of the loader, and ensure that they work normally.
8. Be sure to place a standby external air filter in the cab, so as to facilitate the
replacement of any part which is frozen or affects the breathing of engine.
9. Under cold weather, the start aid shall be sued. Please refer to the contents of
“ Startup of Engine ” relating to start up under cold weather.
10. In order to prevent freezing situation, clear away all mud, snow and ice. If possible,
cover the loader with canvas, and prevent the edge of the canvas from being frozen to the
