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 of 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
ground.
4.7.2 OPERATION UNDER EXTREMELY HOT WEATHER
The continuous operation at high temperature may get the loader overheated. If
necessary, monitor the temperature of engine and gearbox, and stop the loader so as to
cool them down.
1. Inspect and maintain the fan and radiator from time to time. Inspect the level of
coolant in the radiator. Inspect whether the dust, sand and insect which may block up
the cooling pipeline is accumulated on the radiation fin.
①
At high temperature, the generation of scale in the cooling system may be
accelerated. The anti-freezing fluid shall be replaced each year, so as to remain its
function as a corrosion inhibitor.
②
If necessary, clean up the cooling system on a regular basis, so as to ensure that
the pipeline is clean and clear. Don’t use the water which is excessively alkaline,
otherwise the scale and rust may appear more easily.
