There is such noise as

Notice: the braking materials
may generate the natural noise
and heat during friction, and
thus emit the energy. Therefore,
it is normal to have the
screaming noise. These
phenomena will be more serious
under the condition of frigidity,
torridity, and over humidity,
snowing and mud. the

occasionally will not lead the
fatal brake trouble nor reduce

SR-14Steering SystemPower Steering (On-Vehicle Inspection)
Change of power steering liquid
1. Tear down the oil-returning hose from the oil cup to
drain the liquid into the container;
2. Run the engine in the idle status, and rotate the
steering wheel toward the max rotating angle for
several times in right or left direction while draining the
liquid, until the oil in steering liquid is drained up.
3. Turn off the engine.
4. Connect the oil-returning pipe and inject the new
power steering liquid in the liquid tank;
Hydraulic oil type: No.8 Liquid drive oil (Q/SH003.01.012-88)
5. Start the engine, and make it running in the idle status.
Rotate the steering wheel to the max rotating angle repeatedly
several times, meanwhile, supplement new power steering
liquid in the liquid tank until there is no foam or turbidities in
the liquid tank, and the oil indicating lamp reaches the marked
range when the engine is turned off.
6. Tighten the liquid tank cover
7. Exhaust the air in the power steering system;
Ai-r bleeding in power steering system
1. Check the liquid level height in the liquid tank
Check the liquid level and, if needed, supplement the liquid.
2. Start the engine in the idle status and rotate the
steering wheel repeatedly to the max rotating angle
several times.
3. Turn off the engine and connect the ethane pipe and
bleeding plug.
4. Start the engine and rotate the steering wheel
repeatedly to the max rotating angle several times.
5. Locate the steering wheel at the intermediate position.

If there is diode in the circuit, connect the two leads in reverse
polar and make another inspection. When the cathode lead (-)
is connected with the positive (+) side of diode, and the
positive (+) lead should be connected with the cathode (-) lead
of diode, the diode should conduct, while the two leads
connected to the reverse polar, the diode should not contact.
Remark: the specification may be not same due to different
testing meter types; therefore, the application instruction for
testing meter should be referred before the inspection.
Check the light emitting diode (LED) according to the same
approach for diode inspection.
Remark:
The testing meter should be used the one with 3V voltage or the
one has larger resistance than that in circuit.
If no suitable testing meter is applied, the voltage of accumu-
lator may be added to check the LED to see whether it is
lighted.
(c) Use the voltage or ohmn meter with high-impedance
(min voltage of 10 KV) to diagnose the failure in electric
circuit. Body Electric SystemBrief Introduction0

Check to see whether there is short circuit
(a) Tear down the burned fuse and remove all loads from
the fuse.
(b) Connect the testing bubble at the fuse position;
(c) Verify the situation of testing bubble position:
For example:
Put the ignition switch of SW atON position;
Put the ignition switch of SW and SW1 atON position;
Put the ignition switch of SW, SW1 and Relay at
ON position (which connects with the relay), and put
SW2 at OFF) position (or disconnect the SW2).
(d) Disconnect or re-connect the plugging elements when
observing the testing bubble. In case the testing bubble
keeps lighting, which shows there is short circuit between
the plugging elements; if the testing bubble extinguishes,
there is short circuit between the plugging elements.
(e) Shake the trouble wire alongside the body to locate the

AC-2Air Conditioning SystemIntroduction
In case the liquid refrigerant enters into the eye or touches the
skin, the following measures shall be taken:
Wash the part where is touched by the refrigerant with a
great deal of water.
Coat the skin with the clean Vaseline.
See the doctor or go to the hospital for treatment; and
Do not try to cure it yourself.
General Introduction
1. Take notice when handling refrigerant General Introduction
(a) Do not handling with refrigerant in the closed room or
near to open fire.
(b) Safety goggles shall be worn when handling
(c) Be careful to avoid the liquid refrigerant from entering
into your eye or touching you skin.
waterair
dust
ÅçåÇÉåëÉêplug
2. Take notice when changing the parts of refrigerant pipes:
(a) The refrigerant shall be exhausted gradually before
changing.
(b) The dismantled parts shall be covered with plug right
away so as to prevent the water or dust from entering into
the system.
(c) Do not store the condenser or liquid tank under the
condition that the plug has been uncovered. and
(d) Refrigerant shall be exhausted before installing the new
condenser, because the refrigerant, if not exhausted, will
eject out in gaseous form with the lubricant oil when the
plug is moved away.
3. Take notice when fastening the connection parts:
(a) Spread a little lubricant oil at the matching position of the
O-type ring to fasten the connection and avoid of gaseous
refrigerant leakage.
(b) Fasten the nut with two spanners so as to avoid of the pipe
deformation.
AC-3Air Conditioning SystemIntroduction
(c) Tighten the O-ring matching position or the threaded position
to the specified moment.
4. Take notice when connecting measuring meter at branch pipes:
(a) Connect the end of filling hose with high speed joint to the
filling valve of compressor.
(b) Letter D marked on the compressor near the auxiliary valve
represents the side of high voltage while S means the side of
low voltage, which shall be looked out when connecting the hose.
(c) Fasten the bolts by hand, and
(d) In order to prevent the hose from loosing, lubricant oil shall not
be spread at the connection position.
Remarks: after connecting the measuring meter on branch pipes to
the refrigerant container (repairing tank), the air in the hose shall be
exhausted up.
5. Take notice when vacuumizing:
After vacuumizing for 20 min, maintain the container at certain
pressure to ensure that all air in it is exhausted up, and another
inspection shall be made to see whether there is leakage.
6. Take notice when handling with the refrigerant container
(repairing tank):
(a) Do not heat it.
(b) Store the container at the place where temperature is under 40
(c) In case of heating the repairing tank with hot water, care shall
be paid to the valves at the top of tank, do not dip them into the
water, or the water will penetrate into the cooling system.
(d) The empty repairing tank is forbidden to reuse.
8. Take notice when using the high-pressure air cylinder type
inspecting device:
(a) In case the open fire is used, it is the first to ensure before using
there is no flammable material around.
(b) Be careful because toxic gas will be produced when the
gaseous refrigerant meets with the open fire. 7. Take notice in the A/C operation or when adding the liquid
refrigerant:
(a) In case the gaseous refrigerant in the cooling system is
insufficient, which can lead to the compressor burns out, and
such accidents shall be avoided.
(b) If the valve on the side of high pressure is uncovered, the
refrigerant will flow in the reverse direction, which may lead
to the break of the repairing tank, therefore, only valves on the
side of low pressure are allowed to open or closed.
(c) If the repair tank is laid in reverse direction, and the refrigerant
is added in liquid status, the liquid refrigerant will be
compressed, which may lead to failure of the compressor,
therefore, refrigerant shall be inflated in the gaseous status.
(d) Be careful not over-inflate the gaseous refrigerant, otherwise,
such failures as insufficient cooling, increase of oil consuming
or over heat of engine will be followed.

Gearbox
Three-grade maintenance for gearbox
1. Grade I maintenance for gear box
Grade I maintenance: Check the lubricant level to see whether the lubricant level is in alignment with the lower edge of oil
filler; if the lubricant is lower than the oil filler lower edge, add the lubricant; or the insufficient lubricant will lead to the poor
lubrication or burn-out of bearing and teeth; while the over-high lubricant will cause the overheating and oil leakage.
2. Grade II maintenance for gear box
Grade II maintenance: The gear box of a new vehicle should be maintained by exchanging the lubricant during the
first grade II maintenance and should be washed with kerosene; and the lubricant quality should be checked in the
grade II maintenance in later time, if the lubricant is diluted, gumming or over-dirty, it should be changed.
3. Grade III maintenance
The gearbox should be disassembled for inspection, washing and oil change.
Notice: As the new vehicle is in the running-in status, the gearbox should be maintained by exchanging lubricant
after the vehicle covers 1500 km,
