Operation & Maintenance Manual──LG936L Wheel Loader 72 3. The loader must be maintained and lubricated periodically. 4. Drive the loader until the brake pressure reaches 0.4MPa after the engine starts. 5. Put some hot water or vapor in front of the engine for preheating it. Preheat the engine until 30~40 ℃ before starting if the environmental temperature is lower than -5 . ℃
6. There is no need to stop the machine or step on the brake pedal in changing the forward levers during driving. When changing the speed from low to high, release the accelerator a little and operate the Gear Control Lever at the same time, and step on the accelerator; when changing the speed from high to low; release the accelerator first and then change the transmission slowly. 7. After the lift-arm and bucket are moving to the required position, release the control valve lever to the middle position. 8. Change the forward or backward driving direction after stopping the loader. 9. Full load work is allowed until the water temperature of the engine is above 60 and the ℃ mobile temperature of the engine is above 50 . But the water temperature of ℃ the engine should not be over 95 and the mobile temperature of ℃ the engine should not be over 120 , ℃ otherwise stop the loader to cool it. 10. Never lift the bucket to the highest position to transport material. The lower hinge of the lift arm should be 400 ~ 500mm above the ground to ensure stable driving during the transporting process. 11. A diesel engine is used in the machine. The power of the diesel engine will go down as the altitude, environmental temperature and relative temperature goes up. So please pay attention to the environmental conditions and calculate the real power under the current environmental condition according to the power correcting table in Diesel Engine Usage and Maintenance User Manual . 3.2 Starting 3.2.1 Check before Starting z Check the bottom and surrounding of the machine to see whether there are lost of bolts, dirt, oil, coolant leak, or broken parts. Check the status of accessories and hydraulic parts. z Check before Starting: Check the fuel in the fuel tank. Refer to 3.6.2 Adding Fuel to Fuel Tank in this chapter. Check the hydraulic oil in hydraulic oil tank. Refer to 3.6.5 Adding Oil to Hydraulic Oil Box in this chapter. |
