z  There is an indicator on the cover of the battery. The green light means it can be used, the black 

light means it should be charged, and the white light means it should be replaced. Replace with a 

new battery after the white light indicator. 

z  Routinely recharge the battery if the battery lacks electric power during use to prevent the 

capability of battery sulfate going down. 

z  If the battery is installed, disassemble it and put it in a dry and well ventilated place if it is not 

used for long time (generally more than 15 days). Recharge the battery every 3~6 months (based 

on whether the indicator is black or not). 

8.17 Charging of Storage Battery 

Explosion may occur if the storage batteries are charged in the wrong way. So follow the storage 

battery instructions in this user manual. Do as follows: 

z  Charge with constant voltage is recommended: 

¾  Complementary charge: charge 16 hours at 16.0 Voltage (max current is less than 25A) 

¾  Normal charge: charge 24 hours at 16.0 Voltage (max current is less than 25A). 

z  Connect the positive pole of the charging machine with the negative pole of the storage battery, 

and then connect the negative pole of the charging machine with the positive pole of the storage 

battery. Never reverse. 

z  Examine the vent of the battery to prevent blockage, otherwise it may explode. 

z  Lower the charging voltage or current if the electrolytes are over 45℃  to prevent spurt out of 

electrolytes due to high temperatures. 

z  Never overcharge during use or charging to prevent early invalidation due to water loss, grid 

increasing and diachylon dropping. 

 

8.18 Starting to Use Voltage-Raising Method   

The wrong connection of voltage-raising cable may lead to fire, so please do as follows:   

z  Two operators are needed to start voltage-raising start (one sits on the operator seat). 

z  Two machines are not allowed to touch when one is starting. 

z  Turn off all the starting switches of the normal machine and the broken machine when connecting 

the voltage-raising cable. 

z  Connect the positive (+) cable first when the voltage-raising cable is connected. Cut off the

negative or ground (-) cable first when the voltage-raising cable is removed. 

z  Connect the ground cable to the frame of the broken machine. Connection should be as far as 

possible away from the storage battery. 

z  Do not let the voltage-raising cables touch each other or let the clamp touch the machine when 

the voltage-raising cable is removed. 

 

8.19 Maintenance and Storage of Tires 

8.19.1 Maintenance of Tires 

z  The Explosion of a tire can push the parts, such as tire, rim and driving axle, as far as 500m or 

more. The explosion and the particles can lead to severe injury, even death, so please keep the 

pressure of the tire at the normal level. Inflation pressure should not surpass the standing value. 

The inflation pressure is shown in 

CHAPTER II - 8 TECHNICAL PERFORMANCE 

& PARAMETERS

.

 

z  Driving at high speeds increases the temperature, and therefore, the pressure. Never try to reduce 

the pressure, but reduce the speed to cool the tire. Continuous high speed driving can lead to over 

heating and tire explosion. 

z  Stand at the back of the tire, and stand as far as possible away from the tire when adjusting the 

pressure of the tire. 

z  Check the tire and rim every day for cracks or bubbles. Never operate in a low pressure 

condition. 

z  Check that the bolt and nut of the rim are in place. Check whether the torque of the nut satisfies 

the suggested value of the factory. 

z  Never stand in the front or the rear of the rolling direction of the tire. Check the tire from the side. 

If disassembling one tire lock the other tires. 

z  Take care when welding near a tire, which can cause explosion of the tire. 

z  Only a trained person with a professional license can repair a tire and rim using specific tools and 

following the proper steps.   

z  Use the uniform tire with the same standard and same flower pattern for replacement.

8.19.2 Storage of Tires 

z  It is the basic rule that tires should be stored in a warehouse. No one 

can enter without permission. Put a fence around and hang a “No 

Enter” sign if the tires are stored outside the warehouse. 

z  Store the tires in a dry and clean place. Water can oxidize a tire, and 

dirt and oil can erode a tire. No light, heat insulation or ventilation 

are needed for storage. Cover the tires with a canvas, plastic or 

other anti-dust cloth. The wrong storage method can greatly reduce 

the quality and life of tires. 

z  Stand the tire on level ground and use a wedge to lock it to prevent it falling down. The quality 

may be reduced if the tire is laid on its side. The tire should be rotated (90°) once per month at 

least. 

z  Please stand aside if a tire starts to fall down. Never try to hold a tire since the tires for 

engineering mechanisms are generally very heavy, and you may be seriously hurt. 

8.20 Waste Materials 

Do as follows to prevent pollution: 

z  Never dump waste oil under ground or into the river 

z  Contain the oil vented from the machine in a container; never dump the oil directly onto the 

ground. 

z  Obey the relative rules and laws when dealing with harmful materials such as grease, fuel, 

coolant, solvent, filter and storage battery. 

 

9 SAFETY TRANSPORTATION 

9.1 Assemble and Disassemble the Machine 

z  Keep the engine speed low during loading and unloading the machine. 

z  Load and unload machine on level ground and remain at a safe distance off the road. 

z  Secure the tires well during loading and unloading the machine to make sure it will not move. Put 

a cushion under the gangway. 

Operation & Maintenance Manual──LG936L Wheel Loader

z  Slope boards should be strong enough with sufficient length and width to form a safe slope. The 

angle with the ground should not be larger than 15°. Keep a safe distance between slope board 

and board, board and machine. 

z  Make sure the height of the two sides of the board is uniform to ensure firm orientation. 

z  Keep the board surface clean, free of lubricant, oil, ice and loose materials. Clean the dirt off the 

tires. 

z  Never turn around on the slope board. If it is necessary, turn outside the board and then drive 

back. 

z  Lock the direction mechanism after assembly, wedge the tires and tie the machine tightly with 

cords. 

9.2 Transportation on the Ground 

z  Obey the rules about weight, height, width and length prescribed by national and local laws for 

transporting the machine using a tow truck. Obey the traffic rules. 

z  Know the weight, height, width and length of machine regulation before deciding the transport 

routine. 

z  Know the allowed limit of weight bearing when passing bridges or private buildings. Obey the 

relative rules when driving on the public roads. 

z  The machine may be unloaded when using other transportation. Please contact Shandong 

Lingong Construction Machinery Co. Ltd. or their accredited representative. 

9.3 Lifting 

Use the hook of the front and rear frame to transport the 

machine to ship or train. 

Select proper lifting equipment according to the weight 

of the loader, otherwise it is dangerous to surpass the 

weight limit. 

z  Notices for lifting: 

‹  Make sure the loader is in the transporting state. 

The front and rear frame should be in the middle 

position. Lock the machine using the lock bar to prevent rotation of the front and rear frame
