LG936L Wheel Loader. Service manual - part 7

Operation & Maintenance Manual──LG936L Wheel Loader

z Never drive the machine near hanging things or close to a deep ravine. The machine weight or

vibration may cause the ground to collapse, and result in the machine turning over.

z Assemble anti-fall and anti-turn operator cab when working in an area where there is danger of

falling stone and machine turnover.

z Continual rainy weather, earthquake and explosions can cause dangerous working conditions.

Operate carefully in these cases.

z Drive at a low speed, prevent starting, braking or turning suddenly, and use the tire chain on a

snowy road. Brake alternately. Lower the bucket to touch the ground to brake if necessary.

z The load should be decreased to prevent slippage when driving on snowy ground because the

adhesive force may change greatly in the piled snow.

z The road shoulder and other road conditions can not be seen under the snow, so take care with the

snow shovel.

5.8 Driving Safely on the Ramp

z Turnover or slippage may occur when driving on an abrupt hill, dyke or ramp.

z The bucket should be 200mm ~300mm above the ground when driving on an abrupt hill, dyke or

ramp. Lower the bucket and touch the ground to help brake or prevent turn over in emergency

conditions.

z Do not turn on the ramp. Do not drive across the

ramp or change direction which may turn over the

machine.

z Never turn on the ramp until on the level ground. Slow down and a use small turning angle when

working on an abrupt hill, dyke or ramp.

z Go up and down the ramp rather than drive through alleyway or footpath.

z Choose proper gears before going down the slope and never change the speed during going down

the slopes.

z Do not suddenly brake on the ramp because the center of gravity is on the front tire or rear tire.

z Use gear I when driving on the ramp with a full load. Go forward when driving up the ramp, go

backward when driving down the ramp. Never turn around.

z Brake slowly when driving down the ramp; do not set the gearshift control lever in the position of

the neutral gear

z Go down the ramp slowly; never stop the engine.

z If the engine stops on the ramp (slope is less than 15°)，step on the brake padel immediately and

lower the bucket to the ground to help brake, use the parking brake, put the gear control lever in

the neutral position, and then restart engine.

z When driving with a load, the bucket should face the

high direction of the ramp at all times, which means

go up forward and go down backward.

5.9 Towing

△

WARNING

Injury, even death may occur if the disabled machine is towed

incorrectly.

z Follow the direction in

CHAPTER III – 3.5.2 (7) Towing

, a dangerous contion may be

caused by using the wrong method.

z Wear gloves to deal with a tightwire.

z Before preparation for the towing confirm the signals with other people.

z Please contact Shandong Lingong Construction Machinery Co. Ltd. or their accredited

representative if the engine does not start or the brake system has problems.

z Please tow the machine on level ground; it is

dangerous to tow on a ramp.

z If a disabled machine is towed by an other machine,

the tightwire should be strong enough to pull the

weight of the towed machine. The tightwire with

wring or radius reduction can not be used.

z People are not allowed to go between two machines

when the machines are connected.

z Do not stand on the towing steel wires or tightwires.

z Keep the hook of the towing machine and the towing parts in a horizontal line.

6 SAFETY OPERATION

6.1 Keep Good Operation Habits

z Always be seated with the safety belt locked during

operation. The machine in operation should always

be controlled by the operator.

z Operate the control lever of the working equipment

properly to prevent misoperation.

z Examine and listen to the exceptions carefully, and report immediately. Do not repair while in

operation.

z An overload is dangerous. Shandong Lingong

Construction Machinery Co. Ltd assumes no

resposibility for the injury or damage induced by

overload.

z It is dangerous to hit any object at a high speed.

Damage may be done to the loaders, the goods and
the operator.

z Keep perpendicular during loading and unloading

materials. If working in a side direction, the steering
cylinder and differential carriers may be damaged,
and the machine may be unbalanced.

z Confirm the ambient conditions and the operation

before driving to load and unload materials.

z Check the status of the working area before entering

a narrow passageway such as tunnel,

overbridge and

garage. Take care with the working devices during
operation.

z Operate down wind in strong windy weather.

Operation & Maintenance Manual──LG936L Wheel Loader

z Be careful when the lift arm reaches the upper limit.

Loading in the upper limit position may cause
destabilization of loader. So the driving speed should
be slow and the bucket should tilt forward slowly.

z When unloading to the truck or tipper, make sure the

bucket does not hit the truck or tipper. Do not allow

antone to stand under the bucket or to let the bucket

go over the cab of the truck.

z When driving backwards, ensure visibility of what is

behind you.

z Install lighting systems during dark conditions. And

stop work when there is smoke, fog, sand, or dust

which affects visibility.

z When working at night, please make sure:

Proper lighting system is installed.

Fuction light works normally.

To carefully estimate the height and distance of

objectives.

Keep alert and stop the engine and examine the

environment and the machine frequently.

z Make sure that every bridge is strong enough to let

the machine pass.
