z Operating methods
a) Refrigeration
First-time use, turn the air volume and power switch to high gear after the engine started,
turn the temperature control switch to refrigeration. Turn the air volume to obtain low,
middle and high volume of air.
b) Heating
Turn the temperature control switch to the state of off, open the hot water valve the air
volume and power switch, warm air blow constantly. Turn the air volume and power switch
to obtain low middle and high volume of air.
c) Power
indicator
lamp
If the system in a normal energizing the power indicator lamp will come on. If the
refrigeration indicator lamp comes on,
the compressor starts working for the refrigeration of
air conditioning.
Notice:
Avoid the temperature control switch 3 is always in the coolest position and the air volume
and power switch 2 is in the fan low gear (L position), in order to prevent the evaporator
from frosting.
Avoid the sun shining directly in summer.
Please shut the door and window of cab when using the air conditioning; shut the heat source
valve when using for refrigeration; shut the temperature control switch for refrigeration when
using for heating in winner.
Clean the condenser periodically using compress air and cold water, but not using hot water

or steam.
Run the compressor once a week when the refrigeration isn’t used in winner for 1min to
maintain the air conditioning in normal state.
1.2.10 Adjustment of Cab’s Seat
△
!
WARNING
z When adjusting the cab’s seat, park the machine in a safe
place and stop the engine.
z Adjust the cab’s seat before starting operation or replacing
the operator.
z
Make sure that you can depress the brake pedal completely
when your back is against the seat backrest.
z Weight Adjustment
The weight adjustment handle is in the middle of seat bottom.
Turn the handle clockwise to reduce the damping stiffness and
turn anticlockwise to increase the damping stiffness. Rotate the
damping stiffness adjust handle A by hand according to the
operator’s weight until feel comfortable.
z Fore-and-Aft Adjustment
This handle is on the left bottom side of the seat. Pull the
fore-and-aft handle B and move the seat forward or backward to
the desired position; it will lock automatically after pushing it
down.
z Backrest Angle Adjustment
Put the backrest angle adjust handle C upward to pull the backreat until the angle is comfortable. The
backrest angle is locked when loose the handle.
z Height Adjustment
There are three positions for the height of seat, and the operator can adjust according to the need.
During adjusting, set the base under the seat by two hands and draw up forcibly and stably. When the
cracking sound is sounded, please loose your hands, then the seat will fix in this position. Adjust the
position of seat to the highest position and draw up forcibly, and then press down, the seat will fall to
the lowest position.
z Headrest Height Adjustment
Set the headrest of seat by two hands, and then draw up or press down forcibly to adjust the height of

headrest.
1.2.11 Use of Safety Belt
If the safety belt is assembled on the seat, please tie it when operating the machine. Before using
safety belt, please check the degree of wear and firm. Replace it if it is necessary.
Adjust the length of safety belt before using to make sure the safety belt can be used for safety
guarantee and comfort. Move the position of lock on the safety belt to adjust the length of safety belt.
The clamper of the safety belt is at the right side of seat, and put the lock into the opening of clamper
to jam the lock. There is a red button on the side of opening of clamper. Press the button and the lock
will jump out from the clamper. Before using the safety belt, please check the clamper of safety belt
whether lock and loose normally.
1.2.12 Rearview Mirror
Rearview mirrors are on the left and right sides outside the cab and left upper inside the cab. Before
starting work, the rearview mirror must angle be adjusted for a good rear.
1.2.13 Key
This loader equips two key for every using condition:
z The key of left and right doors of cab.
z The starting switch key for engine.
z The key of left and right doors of engine hood.
z The key of left and right otter boards of engine hood.
z The key for adding fuel port of fuel box.
2 RUN-IN PERIOD OF NEW MACHINE
A new machine must have a run-in period first to increase the load step by step from free rotating; so
that each part of the machine can be have full run-in period for increasing the life of the machine. It
needs 60 hours to train the new machine, and operate follows:
z Run the machine in neutral at low-speed to preheat the engine.
z Never accelerate the engine suddenly in the preheating period.
z Never start, accelerate, turn or brake suddenly except in an emergency.
z When the loader is working without a load, the gearshift should be used from low speed to high
speed at each level accordingly. Turn left, right or brake steadily in the process of driving.
z In the period of run-in, all speeds including forward and reverse should be adjusted.
z It is better to load bulk materials in the period of run-in. Do not operate the loader too hard or too
rudely. The load should be less than 70% of the standard load, and the speed should be better less
Operation & Maintenance Manual──LG936L Wheel Loader
71
than 70% of the maximum speed limit.
z Pay attention to the lubricating condition; routinely add and change the lubricant according to
rules.
z Pay attention to the temperatures of the gearbox, torque converter, front and rear frame, rim and
brake drum. Once they are overheating, find the reason and repair it.
z Check the fastening conditions of the bolts and nuts.
Do the following maintenance after 10 hours of run-in time on the new loader:
z Check the fastening status of bolts and nuts of all parts, but especially the bolts of diesel engine
cylinder cover, vent-pipe bolts, front and rear frame bolts, rim bolts, transmission axle bolts and
connection bolts.
z Clean the raw and essential engine oil filter and fuel filter.
z Check the tension status of the belts of fan, electrical machine and air condition compressor
z Check the capacity of the storage battery electrolyte and its reserves, and fasten the connect
poles.
z Check the oil level of the gearbox. Please refer to
3.6.3 Adding Oil to Gearbox
in this
chapter.
z Check the seal of the hydraulic system and braking system.
z Check the connection and sensitivity of all control levers.
z Check the temperature and the connections of the circuit system, the power supply of electrical
machine, gauge, light and lamps and turning signals.
z Open the air storage tank to drain water.
The following maintenance should be done after the run-in period of new machine:
z Clean the filter at the bottom of the gearbox and the oil filter cartridge of the torque converter.
z Check the oil returning filter cartridge of the hydraulic oil tank.
z Change the engine oil. Please refer to
3.6.1 Fuel Supplying of Engine
in this chapter.
3 OPERATION AND USE OF LOADER
3.1 Notices for Usage
1. The diesel must be cleaned and deposited more than 72 hours before it is to be used. The
trademark should suit the rules.
2. Transmission oil for the gearbox, torque converter, and the hydraulic oil for hydraulic system
