Preparative for vehicle operation start up:
Check daily, before turning engine on:
1. Check oil level of the engine
The warning “Engine oil pressure” is displayed as a signal
item on the combination instrument when the oil pressure
is too low, the alarm buzzer sounds, the warning light
STOP comes on, stop the engine and check engine oil level
at the dipstick. Provide immediately for the oil
replenishment to its correct level.
The oil level should always be checked with the vehicle
parked on level ground, before starting the engine up, or at
least 5 minutes after having shut it down.
Open the engine compartment hood.
Take out the oil dipstick, and clean it with a clean cloth
without loose threads, and put it back into its place fitting it
in completely.
Once again pull out the dipstick and check the oil level.
a. The oil should not exceed the maximum level.. drain
the excess.
b. If the oil is at operational level, do not add more oil to
the crankcase.
c. If the oil is at or below the minimum level, add the
same type and brand of oil to the crankcase as that
already there, until reaching the maximum level..
After the checking, replace and fit the dipstick completely
back into its place.
If the oil level is checked after the engine has been run for
a period of time, then it should take at least five minutes
before the measure to ensure the oil back flow to the oil
sump in full.

2 Check level of the coolant
The coolant level is automatically monitored.
If coolant level gets too low，the digital indicator
displays a driver information on the combination
instrument. In this case, park vehicle in a safe place as
traffic conditions permit, stop engine and visually
check the coolant level.
Check the coolant level only when the engine doesn’t
work and its temperature is below 50℃.
The anti-freezing rust-inhibiting engine coolant level
can be observed from the observe pipe.
The coolant level should be between the maximum
level (MAX.) and minimum (MIN.) level indicators in
the compensation tank.
If it is necessary to add coolant to the system:
a. Place the heating system command in the position
of maximum heating potency.
b. Add the coolant to the system up until the
maximum level indication. Only use coolant
which is recommended.
c. The compensation tank cover should not be
opened when temperature of the coolant is still
high to avoid being scalded Place the lid on the
system and turn it to the limit.
d. Pressure valve of the compensation tank should be
opened when adding the coolant to eliminate air in
coolant pipeline of the diesel engine.
e. Run the engine for a short time at varied rotations.
f. Stop the engine and check the coolant level.
If necessary add more coolant to the system
Anti-freeze and antirust solution (mixture of glycol and water) should be added to cooling system from
time to time to avoid sediment, frost, oxidation and increase boiling point.
Note: When adding coolant, please choose the same model to avoid sediment. If coolant is degenerative,
replace it immediately.

3 Fuel pre-filter with water separator (drain accumulated water)
Draining accumulated water
On a daily basis, check the lower cup of the water separator. If there is water in the cup, unscrew the
draining plug one or two turns, to drain the accumulated water.
After draining the water, tighten the draining plug correctly.
When the accumulation of impurities in the lower cup is noticed, take the vehicle to a workshop to carry
out its cleaning.
Changing the fuel pre-filtering element
The fuel filtering element should be changed periodically,
at the intervals recommended in the maintenance manual.
If however, the filtering element is easily saturated
needing substitution at very short intervals, this is an
indication of the accumulation of impurities in the
interior of the fuel tank, and the cleaning of the latter
should be carried out.
In order to change the fuel filter element, take the
vehicle to a Dealer or a King-Long Workshop.
Fuel system discharge
Activate the manual pump until feeling resistance on
pumping.
Start up the engine without accelerating. If the engine
does not start running in 20 seconds, interrupt the startup
and wait at least one minute before trying again.
If the engine insists on not working, repeat the discharge
operation.
Leave the engine running for about a minute to
completely eliminate the air from the system by way of
the auto-discharge system.
In order to reduce environment pollution problems, do
not drain the residues accumulated in the water separator
directly into Nature (rivers, lakes or soil). The drained
residues should be collected in appropriate containers
and taken to receiving centers to have proper final
destination (see local legislation).

5. Vehicle lighting, intermittent lights and brake lights
Check all instruments and indicator lamps for normal, especially the head lamp, the turning lamp, the brake
lamp, the reversing lamp and the danger alarm lamp.
Check the bulb and the switch for their damage. To carry out the lamp substitution, hands should be very
clean. If possible handle new lamps with tissue paper.
Clean the external of all instruments and indicator lamps to ensure clear indication.
Attention!
The traffic laws regulate the location, lighting intensity, and color of the lenses and the quantity of
lanterns for each type of vehicle. The King-Long vehicles leave the factory in strict obeyance of these
specifications. Traffic safety depends on these factors; therefore do not change the place of the lanterns.
Substitute the damaged lanterns only for other original ones. Remember that a change of lantern colors
can confuse other motorists and result in serious accidents. Avoid unnecessary lantern adaptations.
When substituting lamps, use the same type and potency as the original lamps. Do not carry out any
lamp adaptation in the headlights, as this will affect their adjustment and performance, putting the
vehicle traffic safety at risk.
On a regular basis revise the illumination system, keeping it always in perfect working conditions

6. Check the level of AdBlue and the daily maintenance of SCR system
(1) Check the level of AdBlue.
When the vehicle key rotate the ON position, the LED
screen of combination instrument will display the
remain volume of the AdBlue, please see the right
diagram.
The AdBlue consumption is 5 percent of the fuel
consumption. If the remain volume of AdBlue is less
than 12%, the lamp 1 will flash and you need add
AdBlue. If the remain volume of AdBlue is less than 6%,
this lamp will light and the power of engine will be
declined forcibly. This will cause the emission
substandard and it is not good to engine.
(2) The daily maintenance of SCR system
Please add the AdBlue when it is insufficiency. Ensure the AdBlue meet the requirement. Check the SCR
system is well enough and has no leaking before driving. There is obvious add mark in AdBlue tank. If
add substandard AdBlue, must stop the vehicle right now and clean the AdBlue tank, re-filling the
qualified AdBlue. The air filter should be clean and replace regularly.

2. Pneumatic pressure
The air pressure gauge indicates the reserve pressure individually for the front and rear service brake
circuits.
The reserve air pressure in each brake circuit must be sufficient for the correct operation of the brake
system.
The STOP warning light comes on in case of low brake pressure in the service brake circuits.
Attention!
If the driver information indicator displays the warning “brake pressure” and the STOP warning light
comes on with the engine running, it will be an indication that the air pressure is excessively low. Do not
drive the vehicle if the air pressure gauge displays low air pressure in one or both brake circuits, as the
service brake could fail to result in serious accident.

c. Red zone – engine overspeed range (risk of
immediate engine damage)
Always observe tachometer while driving the vehicle.
Whenever possible keep engine running within the
economical range.（green zone）
On downgrade, select an adequate gearbox speed and monitor vehicle speed to avoid engine operating in
the danger range (red zone).
When the exhaust-brake is operating on down grades, select an adequate gearbox speed to keep engine
speed within efficient exhaust-brake operation （yellow zone）.
Always avoid engine over revving (red zone), as engine operation in this speed range can give rise to a
immediate engine damage or seriously jeopardize its durability.
The yellow range with red reticle can be used occasionally when the exhaust-brake needs to be used at its
efficiency limit, however, at risk of engine durability. Therefore, do not operate in this range in a normal
or usual way.

Control periodically, at least once a week:
1. Check tire for abrasion and pressure and tire nut for fixture
The vehicle’s safety and performance depend considerably on the state of the tires, reason why they
should be checked daily.
Before driving a vehicle, check charging pressure of tire for normal, tire for damage, tire nut for fixture.
Note: At initial 50km, please tighten tire nuts of new vehicle to specified torque in appendix.
Tire pressure
Keep the tires always correctly calibrated. The inflation pressure should be checked with the tires cold at
least once a week.
After driving the vehicle for some time, the tires heat and in consequence of the heat, the inflation
pressure increases. Never, under any circumstance, empty heated tires to reestablish the recommended
inflation pressure.
The pressure difference between the assemble tires on the same axle should not be superior to 0.1 bar.
Wheel hubs
Keep them always clean, eliminating eventual mud or other dirt adherence. Substitute the damaged and/or
deformed hubs. The utilization of refurbished hubs is not recommended.
Wheel nut
Without fail re-tighten the wheel fastening nuts of new vehicles after running 50km.
The wheel fastening nuts should be retightened, crosswise, in turns, observing the recommended
tightening torque according to the type of fastening nut. If a torque meter is not available, tighten the nuts
strongly, using the vehicle tools without additional levers.

2. Air cleaner (activate the dust discharge valve to loosen accumulated dust)
The maintenance of the air cleaner is made up of the
substitution of the filtering elements and should be
done only when the maintenance indicator indicates
the saturation of the element.
The cleaning of the main and safety filtering elements
is not recommended. The re-utilization of the filtering
elements can result in deficient filtering of the air and
cause serious damage to the engine.
When washing the engine, conveniently protect the air
inlet with a plastic or similar material to avoid the
infiltration of water to the air filtering element. After
washing the engine, remove the protection from the air
inlet.
Periodically press the dust discharge valve with your
hand, in order to incomplete the dust which possibly
be caught in the internal part maintaining them clear.
At the same time, check clip connecting rubber hose
of air intake system with steel tube in case of dust
entering air intake system due to looseness and
decrease in engine life.
The air cleaner restriction is electronically controlled.
If the indication of saturated air cleaner appears in the
display of digital indicator in combination instrument,
send the vehicle to a King-Long Dealer or authorized
workshop to inspect and clean the air intake system
and substitute the main filtering element.
Indication
The main filtering element of the air filter should be substitutes after maximum 2 years use.
The safety filtering element (optional) should be changed at every third main filtering element
substitution, or after maximum 2 years of use.

Inspection every two weeks before and after driving
Power steering
Ensure that all the maintenance service jobs on the steering
system be carried out at the intervals recommended in the
maintenance manual to guaranty total efficiency and safety.
If any working abnormality in the steering is noticed,
immediately supply the necessary repairs.
The habits of forcing the steering too far against wheel
obstacles and of activating the steering while the vehicle is
stopped are harmful to the steering system and should be
avoided.
In emergencies, in the case of damage to the power steering
system, the steering may be used without hydraulic help,
however, in this condition there will be more steering wheel
play and the steering will become noticeably “heavier”. Drive
the vehicle very carefully and take it to an authorized
King-Long Dealer or Workshop to re-establish the correct
working order of the steering system.
Important: In the case of damage to the hydraulic steering
pump or of the total loss of fluid from the hydraulic system,
we recommend that the vehicle is not driven further than
50KM in order to avoid further damage to the steering system
components.
Power steering fluid level
The power steering fluid level should be checked while the
engine is running at idle and the fluid is hot. Run the engine at
idle gear and turn the steering from side to side various times
to heat the steering system fluid.
Check the level through the inspect window of the container.

General state and tension of drive belts
Check the tension of engine belt, fan belt and compressor belt, if loose, tension it; if damaged, replace it.
Do not start up the engine without the drive belts. In the case of one of the belts breaking, immediately
stop the engine and have a new belt put in.
The checking, adjustment or substitution of the drive belts should be carried out with the engine shut
down.
Check cross plane of the belt for no cracks. Crackle in the transverse direction (along the belt width
direction) is acceptable while that in longitudinal direction and transverse crack cross is unacceptable.
Please replace the strap in case of abrasion or chip dropping off.
Too tight or too loose belt would make against proper operation of engine. Press belt to check tension.
Please refer to the manual book of engine assembly for detailed adjusting method and tension of belt.
The poli-V belts demand technical knowledge, therefore we recommend that this job, when necessary, be
carried out at a King-Long authorized Dealer or Workshop.
Fan drive belts
If it is necessary to replace the fan drive belts in emergency situations, adjust their tension in such a way
that upon pressing them with one’s thumb in the middle of the distance between the pulleys, a defection
of approximately 20mm is observed. Loosen fastening nut of intermediary pulley before turning the
adjusting bolt. After adjusting fan belt tension, tighten the fastening nut of intermediary pulley firmly.

Engine start up and shut down
Procedures for engine start up
Activate parking brake.
Place the gear box lever in neutral. Start up is not possible in gear position.
Turn the ignition key into start position.
Start up without stepping on the accelerator. If the engine does not work after about 20 seconds, interrupt
the start up process and wait at least 15 seconds before activating start again. To repeat start up, it is
necessary to turn the key back to the off position.
Let the ignition key loose as soon as the engine starts running.
The engine rotation adjusts itself automatically in accordance with the coolant temperature alteration.
After engine start up, the vehicle can be put immediately into operation.
Note：
a. The engine should be running at low middle speed for 3-5 minutes on every day's first starting before the
driving.
b. Never race the engine without warming up. During cold start, increase engine speed slowly and do not
make engine run at maximum speed until water temperature of engine reaches to 70°C. At any time, do not
make engine run at high speed under no load.
c. Never make engine run at idle speed for more than 10 minutes.
d. The oil pressure should be displayed on the dashboard in 15 seconds after the engine is started, otherwise,
stop engine to check..
e. If parking brake indicator lights, indicating that parking brake has not be released.
Attention!
If on starting up the engine, the engine oil pressure indicator continues indicating low pressure, this means
that the engine running order is in danger. Immediately shut down engine, find and correct the failure.

Engine shut down
Loosen accelerator pedal.
Place the gear box lever in neutral position and apply the parking brake.
Turn the ignition key to the off position, without accelerating.
Note: After engine runs at heavy loading, temperature of cooling water is higher than 90ºC, so do not stop
engine at once. The stalling should be made only after the engine has been running for a period of time and the
water temperature lowed to the normal range. The parking brake is achieved by setting the hand brake handle
on the control position after the stalling. The shift should be switched to the neutral position and power supply
shut down. Please make necessary inspection of engine and then troubleshoot.
Cautions
Cautions during the winter operation
① Please add long life coolant to cooling system.
② After parking, please exhaust water in air tank in time.
③ Before winter comes, please check level of battery electrolyte, specific gravity and voltage.

Starting the vehicle
The vehicle could only be started when braking system pressure has reached 5kg/cm2 above and each
instrument and indicator lamp is on the proper condition, and the coolant temperature exceeds 60℃ as well
as the parking brake has been released after the engine is started. Please make the startup in shift I.
On normal running condition:
Pointer of oil gauge should be between 0.2 and 0.4Mpa（2-4kg/cm
2
）.
Pointer of water temperature gauge should be between 83℃ and 95℃.
Pointer of barometer should be between 0.55 and 0.8 Mpa（5.5-8kg/cm
2
）
After the vehicle starting, gear shifting should be made step by step and timely. The clutch pedal should not be
released abruptly to impulse the starting when the vehicle is stuck in the mud or can not start on a spoil road.
The following problems should also be paid attention to during the driving
① If abnormal noise or odor occurs, please stop vehicle to check.
② Abrupt acceleration or emergency braking should be avoided as might.
③ Don't put foot on the clutch pedal during the driving.
④ Avoid engine overspeed. When driving long downhill, engine may overspeed easily after gearshift, at
this time, pay attention to apply exhaust brake or retarder and service brake to ensure engine run at
specified speed.
⑤ During driving downhill, never stop engine, otherwise, resulting in low pressure in brake pipeline
and power steering gear failure.
During normal running condition, the pointer of water temperature gauge should be under the red sign that
indicated the vehicle is on normal condition, if the pointer is on “H” indicate it is abnormal.

Parking the vehicle
The parking brake should be always applied when the vehicle is parked.
Additionally, in some countries, it is determined by law that a vehicle parked on a slope must have at least
one of its wheels wedged, to prevent its accidental moving.
In this case, always keep an appropriate wedge available for this purpose aboard the vehicle.
When parking on public highways, obey the legal determinations as far as the use of parking lights or
reflecting panels.
Parking brake handle
Pushing forward the brake handle is of driving state.
Pushing backward the brake handle is of parking state.
Always activate the parking brake when the vehicle is
parked.
Besides activating the parking brake, when parking on
upward or downward slopes, wedge one of the vehicle
wheels to avoid the accidental moving of the vehicle.
Application
Attention!
On applying the parking brake, always check the
locking of the lever in the total braking position, on
the contrary, the lever may return automatically to the
brake off position.
Pull back the parking brake valve lever in such a way
that the lever is locked in total braking position. The
parking brake warning light should light up.
Note:
In emergencies, with the possible failure of the service
brake, the parking brake can be used as an emergency
brake. In this case, slowly pull the parking brake lever
allowing for a progressive braking without abruptly
locking the wheels.
