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 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 “Start
up 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.
