Operation & Maintenance Manual──LG956L Wheel Loader
necessary to change the kind of fuel according to the ambient temperature.
z Always fill the fuel tank full after operating to prevent the water, which is condensed by the
moisture in the air, from entering the fuel tank.
z If the engine fails to suck fuel or the filters have been just replaced, drain out the air in the circuit.
z Always use glycol type engine antifreeze as coolant..
z If the engine overheats, add coolant until the engine cools down completely.
z Add coolant to specified level. If the level is too low, it will cause the overheating of the engine
system and the corrosion of the cooling system.
z Antifreeze is flammable. Keep fire away when adding the antifreeze.
z When adding antifreeze, select different types of antifreeze according to the condition of
circumstance, the recommended range to select is:
If the ambient temperature ≥-15℃ use -25#
If the ambient temperature ≥-25℃ use -35#
If the ambient temperature ≥-35℃ use -45#
z Lubricant is used to reduce noise and prevent wear on the joint surfaces.
z Joints not included in the manual (connectors, jointing sleeves) are treated during overhaul. So
they do not need be lubricated. When some parts become inflexible because of long-term
operation, it is necessary to add lubricant.
z Remember to wipe off the overflow lubricant when adding it.
2.1.4 The Storage of Oil and Fuel
z Prevent water, dirt or other impurities from mixing with the oil.
z Follow the rule, first in first out, to maintain oil quality during long-term storage (Use the oil with
the longest shell life).
z Filters are extremely important safety components. They can prevent impurities in the fuel from
entering important equipment and causing problems. Replace all filters periodically. For the
maintenance cycle, refer to 3 CONTENT OF MAINTENANCE, in this chapter. Replace filters
at shorter intervals when the machine works in a severely bad environment.
z Never try to clean paper filter elements and use them again. Always replace them with a new
z When replacing the oil filters, check whether there are some metallic particles adhering to the old
