The micro CPU will provide the normal information if it
checks each unit in the normal situation. And the
operators can execute the balance operation. When
balancing, MCPU can control the rotation of the
balancer tester main shaft through the drive interface.
The unbalance signal sensed by balance sensor is sent
to the micro-processor port through A/D converter. CPU
will integrated analyze the unbalance signal and angle
signal to calculate the unbalance value and display the
value through the LED unit. We can realize the
man-machine talk through keyboard and LED.

necktie, long hair, loose clothing. The operators should
stand beside the machine when operation the machine.
Keep from the unauthorized personnel.
5.1.7 Before balancing, you must confirm the
installation of the wheel suitable. Before rotation, be
sure the nut turn 4turns around the thread shaft and
firmly locked on the main shaft.
GENERAL CONDITIONS OF USE
The wheel balancers described in this manual must be
used exclusively to measure the extent and position of
car wheel unbalances, within the limits specified in the
technical data section. Furthermore, models equipped
with motors must be provided with a suitable guard.
Any use other than
those described in this manual is to be considered
improper and unreasonable.
Do not start the
machine without the wheel locking equipment.
Protective hood
plays the role of prevention and safety.
Do not clean or
wash the wheels mounted on the machine with
compressed air or jets of water.
Get to know your
machine. The best
way to prevent
accidents and obtain top performance from the
machine is to ensure that all operators know how the
machine works.
Learn the function
and location of all the controls.
Carefully check that
all controls on the machine are working properly.

6.3.2 MOUNT WHEEL
Preparation before test:Check and clean the dust and
mud and if there are foreign bodies, such as metal
and stone, clipped on the surface of the tire. And also
check the air pressure of the tire is according with
the specified value. Check if there are deformation on
the rim positioning surface and installation hole.
Check if there are any foreign bodies in the tire. Take
off the original weight.
The installation methods of the wheel : Positive
positioning, negative positioning & flange disk when
handling the middle and big sizes of tires. You can
select the methods according to the different
conditions.
6.3.2.1 SMALL CAR WHEEL POSITIVE POSITION
Positive positioning is the normal method. It is featured
with simple and quick operation. It is mainly suitable to
the common steel rim and aluminum alloy rim with
small deformation.

weight adding position will be indicated.
6.4.7Rotate the wheel, when the left side positioning
lamp all light, at this moment, the highest position is the
inner unbalance position and when the right side
positioning lamp all light, at this moment, the highest
position is the outer unbalance position.
6.4.8 Add the corresponding weight at the unbalance
point and start test again until the balance of the tire.
1. When start the machine, use hand to pull the wheel
to help it start rotation, especially to the relative
bigger tire, to prolong the working life of the motor.
2. Check if there are any mistakes on the dimension.
3. Check if the balance methods meet the
configuration of the rim and select the balancer
most easily to balance.
4. Check if the quick lock nut tight or not.
5. When the balance ends, remove the tire. Pay
attention to handle it with gentle and avoid
knocking the main shaft.
6. When clipping the weight. Use the hammer to clip
the weight on the rim without too much force. Do
not knock the main shaft hardly to avoid damaging
the sensor. The position to add the Weight should
be free from the grease and should be dry.
6.5 RESIDUAL UNBALANCE VALUE DISPLAY
The minimum value of the standard weight is 5g so if
the weight you use is less than 5 g, the wheel balancer
will not display the value and only displays the state of
“00”. When you need to display the residual unbalance
value, you should press
and the display will
immediately display the inside or outside unbalance
value of less than 5g. The maximum residual
unbalance value is 4 g.
corresponding key to select the balance mode. When
you switch on the machine the machine will automatic
enter into the dynamic balance mode and no need to
select.
Dynamic—clip the weight on both side of
rim (dynamic balance test once start )
Static—use this mode when there can not
add weight on both sides
Mot—optional for balancing the motorcycle
When balance the motorcycle, you need the
special motorcycle adaptor accessory and
with the assistance of the extension scale to measure
Di, Br and Di. Input the measure value into the Di, Br
and Di display window. The input method is similar to
the parameter input of the car.

ALU mode and the configuration of the aluminum alloy
rim is similar to the above standard ALU1\ALU2\ALU3,
you can get relative accurate balance effect. If the
section of the tire similar to the one given be the

and weight of the weight. General speaking, 1~2 times
of adjustment can reach relative satisfactory balance
effect.
