z  Please use the repair tools correctly; do not use broken or low quality tools. 

z  Lower the working equipment completely to the ground, stop the engine, push the parking brake 

switch,

 

and wedge the tire during repairs to prevent bodily injury.   

z  Obey the rules of warning labels. Pay attention to the important notices on the label on the 

machine and obey the rules. Add a new one or clean the label if it is lost or dirty. 

z  Attach the label of “No Operation” or other warning label to the switches or control board 

during repairs. Never let other people operate or start the engine to prevent injury or death. 

z  Fuel, mobile oil, grease and an oily cloth are dangerous materials which should be kept away 

from fire or flame. Do not pile oily cloths anywhere because it may self-ignite.

the handrail around and put the “No Enter”warning 
label to prevent people from entering without 
permission. 

z  No people are allowed to get close to the machine or 

accessories without permission. 

z  Keep the working area clean and tidy, without 

flammable materials around to prevent fire or 
slippage. 

z  Lock the front and rear frames with a safety bar to 

prevent rotation before examination and repair. 

z  Make sure all the levers (or handles) are in the 

neutral position and use the necessary equipment to 
support the life-arms cylinder and tilting oil cylinder 
to prevent the working equipment from falling if you 
have to examine and repair when the bucket is 
lifting. 

8.2 Working in a Close Area 

Exhaust gas from the engine may cause disease or death. If working in a close area, use releaser to 

release the exhaust gas in the area. If there is no releaser, please open the door. 

8.3 Maintenance of Frames During Jacking up 

z  When jacking up the frame, do not let anyone enter the other side of the frame.

8.6 Maintenance While the Engine is Working   

Routine maintenance of the machine should never be done while the engine is working. When it is 

necessary, please follow the rules below: 

z  Assign an operator to sit on the seat to ensure all the 

maintenance people can have contact with him so he 

can prepare to shut the engine when requested. 

z  Never touch a high temperature part such as tail pipe 

and silencer to prevent injury. 

 

z  Be careful if the repair space is near the rotation part.   

z  Do not touch any lever (or handle). If necessary to 

touch it, warn the others to go to a safe place. 

z  Never let any tool or body part touch the fan leaf or fan belt. Otherwise serious hurt may occur. 

z  Do not make adjustments unless fully trained to do so. 

 

8.7 Do Not Let Anything Fall into the Inner Part of the Machine   

z  When opening the examination window and the oil filling port of the oil tank, make sure that 

nothing (such as nuts, bolts, cotton yarn or tools) falls into the inside of the machine. If it happens, 

the machine may be disabled. Pick out the fallen pieces safely.   

z  Do not carry any unnecessary tools or parts in your pockets during examination of the machine. 
 

8.8 Cleaning 

z  Wear the anti-slide shoes to prevent sliding when cleaning the machine. Wear protective clothes 

when using high pressure water to clean the machine. 

z  Clean routinely to prevent dirt or mud splashing into the eyes or slippage caused by oil on the 

machine. 

z  Do not use a flammable scour when cleaning the machine. 

z  Shut the engine to clean the inner part of the machine, put all the levers (or handles) in the neutral 

position, push the parking brake switch and keep it in the braked position. 

z  Do not let water enter an electric part (such as sensor, wire connector) or operator cab. If so, the 

Operation & Maintenance Manual──LG936L Wheel Loader

operation may be disabled and the electric circuit may be damaged. 

z  Wear protect clothes and glasses when using compressed air to clean the filter mesh. 
 

8.9 Heavy Materials 

z  Wear protect clothes, safety glasses and safety helmet and put a copper bar between the hammer 

and the part being hit. 

z  Eyes may be damaged by flying hard particles, such as pin and bearing when hit by a hammer. 

z  Use tools and heavy materials carefully. Prevent them falling down. 
 

8.10 Welding Repair 

Electric welding requires a special technique, proper equipment and place. No person is allowed to 
weld without a license. Escaped gas and damaged electric wires are potential problems during 
welding. Obey the following: 
z  Switch off the electricity in the terminals for storage to prevent explosion. 
z  For loaders with ZF controlling units, disconnect the wire nipples on the computer control panel, 

to protect the computer control panel from being burnt out by the impulse current generated in 
welding. After repairing, do connect the wire nipples on the computer control panel according to 
requested, or the machine will not work. 

z  Clean the paint at the welding site to prevent the production of harmful gas. 
z  Avoid welding on the hydraulic equipment or pipe, or places nearby. Flammable steam and 

sparks may be generated.   

z  Cover the rubber, wire or pressure pipe and use 

anti-fire plate during welding because a spark may 
cause a sudden crack or shatter the insulating tape. 

 
 
 
 
z  Be careful when welding near tires, which may cause 

a thermal explosion. 

z  Wear protective clothes during welding. 
z  Keep the welding area ventilated. 
z  Clean up the flammable materials and check the fire extinguisher.
