Operation & Maintenance Manual──LG958L/LG959 Wheel Loader
z
Strictly choose the fuel brand according to this manual.
z
The fuel may be frozen at low temperatures (particularly temperatures lower than -15℃). So it is
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.
2.1.2 Coolant
z
In order to avoid causing scale which can make the radiator stop or influence the performance of
dispelling the heat, please always use glycol type engine antifreeze as coolant about Shandong
Lingong stated in whole year. Strictly forbid to use water as to coolants.
z
Use Engine antifreeze of glycol type 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 the antifreeze choose different model according to the ambient temperature.
recommend range:
If the ambient temperature ≥-15℃ use -25#
If the ambient temperature ≥-25℃ use -35#
If the ambient temperature ≥-35℃ use -45#
2.1.3 Brake fluid
z
Never mix the brake fluid with different brands. If you want to replace new oil that is different
from the used one, drain the used brake fluid radically, and conduct a feasibility test before
replacement, or the problems caused by the replacement of brake liquid will lead to the failure of
brake and cause accidents. SDLG Construction Machinery Co., Ltd. will not be responsible for
the results.
z
In order to maintain and use your machine, please use the specified brake fluid according to the
requirements of SDLG.
2.1.4 Lubricant
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.
