z  After dumping, use the bucket to level equipment (if assembled). Rear tilt bucket to level position, 

and operate the working equipment control handle to allow the lift arm to lower to prepare for 

next operation. 

(5)  Pushing Operation 

Level the bucket to the ground, and push the accelerator to 

move forward. If there is blockage during moving, raise the 

lift arm a little and move forward continuously. When 

operating the lift arm to lift or lower, operate the control 

lever between lifting and lowering operation. Never use the 

lever at the raising or lowering position to ensure pushing the bucket smoothly. 
 

 

 

 

 

 

(6)  Striking Operation 

Tilt the bucket to let the blade touch the ground. 

For hard ground, put the lift arm control lever in the 

float position; for soft ground, put the lift arm control 

lever in the neutral position. 

Use reverse gear to strike the ground with blade. 

 

(7)  Towing Operation 

!  

WARNING

 

Before towing, the tires must be blocked by the parking brake to 

prevent the machine from rolling. 

During towing, be careful to prevent severe and fatal injury. 

z  If possible, the engine of the towed machine should keep the engine running to ensure braking 

and turning is possible. 

z  If the towed machine engine can not start, disassemble the front and rear transmission axle. If the 

machine can not turn, disassemble the steering cylinder. 

z  The connection hole of the rear frame at the inner side of the rear wheel can only be used for 

!

 

NOTICE

 

Watch the torque converter oil temperature gauge all the time 

during a pushing operation. If the temperature is too high, stop 

the machine to let it cool down and then continue to work.

lifting and binding, but not for towing. 

z  If there is no braking system for the towed machine, never use soft towing but use fixed towing 

or use towing bar. Connect the towing bar to the towing pin at the back of the loader. 

z  If there is no braking system on the towed machine, no one is allowed to stay on it. 
z  Check whether the towing rope and towing pin are strong enough to suffer the weight of the 

towed machine. If machine will pass over clay ground or go up a slope, two towing ropes and 

towing pins should suffer at least 1.5 times the weight of the towed machine. 

z  Try to decrease the towing angle of the towing rope to ensure that the angle between the towing 

rope and the towed machine is within 30°. The height of the towing points of the two machines 

should be close. 

z  The connection between the towing equipment and the machine should be strong. 
z  The weight of the towing machine should be heavier than the towed one, and have enough 

traction power and braking power to be able to pull or brake two vehicles going up and down a 

slope. 

z  When towing the machine down a slope, the machine should have sufficient traction power and 

braking power. Another towing machine should be used to pull at the back side to prevent the 

towed machine from losing control or turning over. 

z  Start to tow and brake gently, at the low speed, and turn on the warning flash lamp. 
z  The speed for towing the loader should be within 10 km/h. Try to tow the machine to the nearest 

repairing garage. If the distance is longer than 10 km or the towing speed faster than 10 km/h, the 

front and rear transmission axle must be disassembled or put the loader on towing truck for 

transportation. 

 

3.5.3 Operation in Cold Weather 

Attention for cold weather 

If the temperature is very low, the engine will be difficult to start. And the radiator may be frozen, so 

please do as follows: 

z  Use fuel with low viscosity, and add antifreeze into the hydraulic oil and lubricant and coolant. 

Refer to 

CHAPTER IV 2.2.1 Selection Table of Fuel, Coolant and Lubricant

, for 

the details of using oil. 

z  Attentions for using antifreeze: 

1.  Do not use antifreeze containing formaldehyde, ethanol or propanol. 

2.  Never use any waterproofing agent independently or together with antifreeze. 

3.  Never use antifreeze with different trademarks together. 

Operation & Maintenance Manual──LG956L Wheel Loader 

 89

4.  Replace antifreeze with the proper ratio according to the requirements. Please refer to 

CHAPTER IV 2.1.2 Coolant

 

!    

NOTICE

 

Keep away from fire when adding antifreeze. 

 

z  Attentions for using the storage battery: 

1.  If the temperature goes down, the capacity of the storage battery will go down too. If the 

charging ratio of the storage battery is low, the electrolytes may be frozen. Please ensure the 

charging ratio is near 100% and try to preserve heat, so that it is easy to start the next day. 

2.  If the storage battery is frozen, never charge the battery or start the engine. Refer to 

CHAPTER I 8.16 Maintenance of Storage Battery

, to disassemble the battery 

and put it into a hothouse or warm water (NEVER let water enter the battery). Warm it to 

15  slowly, otherwise 

an explosion may occur. 

3.  Please use an anti-alpine storage battery in an anti-alpine area. 

z  Follow-up after every working day: 

In order to prevent the materials from freezing on the machine which may affect it working the next 

day, please do as follows: 

1.  Completely clean the silt and water on the machine to prevent silt, water or snow entering the 

sealed parts which may freeze or break the sealed parts. 

2.  Park the machine on the dry and hard ground. If that is impossible, park the machine on a 

wooden board, which can prevent the tires from freezing on the ground. 

3.  The capacity of storage battery will obviously go down in cold weather. So cover it or move 

the storage battery to a warm place, and install it the next day. 

4.  When the temperature is below 0  and there is no antifreeze in coolant

 water, please open 

the water drain valves located at the bottom of the water tank and the engine. Then drain all 

the coolant water in the evaporators of the cooling system and the air-condition system (if 

assembled) to prevent cold cracks. If antifreeze is added, please follow the rules on the 

nameplate of the antifreeze. 

 

 

After cold weather: 

After the weather is warm, the relative parts should use the proper engine oil, fuel and hydraulic oil 

that are appropriate for the temperature.

3.6 Oil and Fuel Supply 

3.6.1 Engine Oil Supply of Engine 

 Oil Level Checking 

!  

NOTICE

 

An oil level check must be executed 15 minutes before engaging the 

engine, or after stopping the engine.

 

z  Park the machine on level ground, and put the transmission lever in the neutral (“N”) position. 

Pull the brake valve manual control handle or press the parking brake switch to brake, and put 

blocks in front and back of tires. 

z  Open the side door on the right side of the engine cover. 

z  Pull the dipstick out, and wipe it clean with a cloth. Insert the dipstick back, and pull it out again 

to check the oil level (at least twice). 

„  Weichai WD10G220E13 engine: The oil level is normal if the oil level is between ‘H’ and 

‘L’ limit; If the level is lower than the ‘L’ limit, oil should be added by the oil adding port. 

 

„  Shangchai C6121ZG50B engine: The oil level is normal if the oil level is between ‘Still 

full’ and ‘Adding oil’ limit at the still side of the dipstick; If the level is lower than the 

‘Adding oil’ limit, oil should be added by the oil adding port.
