Operation & Maintenance Manual──LG956L Wheel Loader 107 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 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# 2.1.3 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. 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). 2.1.5 Filters 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 one. z When replacing the oil filters, check whether there are some metallic particles adhering to the old |
