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 2 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.

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.

Operation & Maintenance Manual──LG936L Wheel Loader

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 Fuel Supply of Engine

Fuel Level Checking

①

△

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 parking brake switch, 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).

Operation & Maintenance Manual──LG936L Wheel Loader

Yuchai YC6B125-T10 engine: If the oil level is lower than the ”L” line, oil should be added

by the oil adding port; It is a suitable oil level if it is between the “L” and the “H” line.

Weichai TD226B engine: If the oil level is lower than the ”L” line, oil should be added by

the oil adding port; It is a suitable oil level if it is between the “L” and the “H” line.

Dongfeng Cummins 6BT5.9 engine: If the oil level is lower than the adding oil graduation

line, oil should be added by the oil adding port. If it is higher than the oil full graduation line

(FULL), check the problem and solve it. It is a suitable oil level if it is between the adding

oil graduation line and the oil full graduation line (FULL).

z Lay back the dipstick, close the side door on the cover of engine. For choosing the appropriate oil

please refer to

CHAPTER IV 2.2 Oil Selection

Engine Oil Replac

②

ement

z Park the machine on level ground, and put the transmission lever in neutral position. Pull the

parking brake switch and put the blocks in the front and back of the tires. Start the engine and run

at idle status until the oil temperature reaches 20℃～40 , then stop the engine.

℃

z Rotate the oil drain plug and let the oil flow out

and hold it in a container.

z After the oil is released completely, rotate the oil

drain plug back and open the right side door of

engine cover; add prescribed engine oil (about

12L) from oil inlet of engine. Run the engine at

idle status, check whether the oil filter and oil

releasing plug are leaky.

z After the engine was stopped for 15 minutes, let

the engine oil flow back to the oil pan, and check

the engine oil level of the engine again.

Engine oil Filter Replac

③

ement

z Clean the area near the engine oil filter. Disassemble it with filter elements spanner.

Assemble

z Add diesel oil full in the filter element and smear engine oil on the rubber seal ring.

z Tighten 3/4~1 cycles after the seal ring connects with the base.

z Start the engine and check whether the seal ring is seal. If not, disassemble the filter element and

check the sealing surface.

△

NOTICE

z After changing the filter elements, the engine must run in the idle

status at least 1 minute to ensure the engine is lubricated

sufficiently before working.

Over tight mechanical rotation could damage the screw thread or

filter element sealing.
