Precautions of working in cold or high temperature area
1. Working in cold weather
The cold weather may cause some trouble, so the protection is very
important at this time. Avoiding the machine to be badly damaged, if
maintain machinery adequately, it will extend machinery life.
1) Electrical system: keep the battery clean and charge fully. Check
the cable and joint, clean the joint then apply a layer of grease at
it to prevent it from rusting
2) Lubricants: apply the lubricant moderate in viscosity at every joint.
Please use the recommended lubricant fit for this machine.
3) Fuel system: check if the fuel supply is suitable for the cold
climate at that time, and change into fuel in low viscosity.
Check if there is water in the fuel system. In cold weather,
moisture content will gather in the fuel box, so check whether
there is moisture content in the fuel filter once working every 50
hours each time. If there’s no water inside, extend the inspection
cycle, or else, check the oil tank.
4) Cooling system: before operating the machine in cold weather, it
is necessary to check the coolant if it is mixed at a suitable
proportion, and the coolant must be the right one which is fit for
the environment temperature.
5) Work equipment: before starting the engine, put the throttle lever
in low idle, start the machine slowly, then stop traveling to
operate the work equipment for about 10mins or till every
hydraulic cylinder working normally.
2. Working in hot weather
To avoid the machine is damaged, follows these rules:
1) Make sure the quantity of liquid coolant in radiator is normal
2) Before the hot weather coming, check the radiator and change
the coolant if necessary.
3) Removing the dirty and fouling on the surface of radiator and
engine.
4) Check the fan belt.
5) Use the lubricant in moderate viscosity.
6) In the cooling system, use the appropriate mix of coolant.
7) In the condition of the large dusty environment, air filter should be
often checked.
