Introduction
Principal of Power Steering
The power steering is a kind of hydraulic device that use
the engine power to steer. The engine drive the power
steering oil pump to generate the hydraulic pressure, which
actuates the piston in steering gear, so that the worm shaft
can provide to the piston with a supplementary force, which
has relation with the pressure actuated on the piston.
Therefore, pressure increase is required if larger steering
force is needed, and the pressure variation is accomplished
through the control valve.
Intermediate position (forward straightly)
The liquid from the power steering oil pump is sent to
the control valve, which, if locates at the intermediate, will
allow the liquid to pass and enter into the drain outlet, finally
return the pump. At this time, it is difficult to increase the
pressure; meanwhile, due to the equal pressures at the both
sides of the power piston, it cannot move toward either side.
Steering time
When the steering drive shaft move toward either side,
the control valve will move together with it, in case one oil
passage is shut off, meanwhile open the other larger, the
liquid flow variation will increase the pressure, as result, the
unequal pressure at both sides of piston will make the piston
move toward the side of smaller pressure, therefore, the
liquid is pressed in the pump through the control valve.

6. Exhaust the air in steering system:
(a) Loosen the bleeding plug;
(b) Screw up the bleeding plug when there is no air bubble
exhausted from the pipeline.
Notice: take care not let the ethane pipe slide from the
bleeding plug, because the liquid is high in temperature
and pressure.
7. Check to see whether there is air bubble or turbidities
in the oil cup, and ensure the liquid level will not
exceed the max value when the engine stops,
Measure the liquid height under the condition of engine running,
then turn off the engine and measure the liquid height again.
In case any problem is found, repeat the approaches of (5) and
(6) in Power Steering Liquid Change. If the problem still
exists, repair the power steering oil pump.

Introduction
(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.
