6.3 BASIC OPERATION
6.3.1 Switch on the main switch on the left side of the machine，the display will display
[888]-[708][Uer]-[2.140] and then[ 0]-[ 0]（it will display [0.00]-[0.00] in ounce state）
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.
Main shaft wheel（direction of the rim installation surface is inside）cone quick nut

17
6.3.2.2
When the deformation of the outside of the wheel, adopt this method to positioning to grantee
the accurate positioning of the steel rim inner hole and main shaft. It is suitable to the steel rim,
especially the thick ALU
Main shaft lower spring suitable cone wheel bowl quick nut
6.3.2.3 FLANGE DISK POSITIONING（OPTIONAL）
Suitable to the big tire assemble
Main shaft flange disk（fixed on the main shaft）wheel cone quick nut
NOTE:The choice on the cone should be adapted to the rim center hole and pay attention
to its direction. Or it will cause the inaccurate measurement.
6.4 INPUT VALUE
6.4.1 Input DIS（Distance）
Pull the scale to the inner position to add the weight and press the key to

18
input the DI value into the display. At this moment, the display will display[DIS]：[XXX]，And the
default system is mm.
6.4.2 Input Br (RIM Breadth) Value
Use the Br measurement caliper to measure the Br of the rim, press the key to
input the Br value into the display. At this moment, the display will display [Br. ]：[XXX]. and the
default system is inch.
6.4.3 Input the DiA(Diameter)Tire Diameter Value
After confirming the rim diameter, press the key to input the rim diameter into
the display. At this moment, the display will display [Dia ]：[XXX]. and the default system is
mm.
6.4.4 UNIT CONVERSION：
①The unit conversion of the Br of the rim from inch to mm:
Normally, the display of Br should be in inch. When you need the unit of the display to be mm,
you can use the key to realize the unit conversion from inch to mm.
②The unit conversion of the DIA of the rim from inch to mm:
Normally, the display of D should be in inch. When you need the unit of the display to be mm,
you can use the key to realize the unit conversion from inch to mm.
After unit conversion, the unit of the display values of rim Br and D value, but when you switch
off and then on the wheel balancer, the unit will be still inch.
③The unit conversion from gram to ounce：
Normally, the unit of the unbalance value is gram (g). If you want to make the ounce (Oz) to be
the unit, you can execute the g/Oz conversion. The unit of the displayed unbalance value is
gram（g）. The way to realize the unit conversion from gram to ounce is to press
6.4.5 When press the start key，the wheel balancer starts to run. A few seconds later, the
machine automatically stops. The machine can also start by lowering down the protective hood
which can be set by the program.
6.4.6 DISPLAY UNBALANCE VALUE
When the spin ends, the display will display the inner and outer

19
unbalance value of the rim. Use your hand to pull the wheel. When all the positioning lamps
light inside and outside light, the 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.
Attention：
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. Check if the balance methods meet the
configuration of the rim and select the balancer most easily to balance.
3. Check if the quick lock nut tight or not.
4. When the balance ends, remove the tire. Pay attention to handle it with gentle and avoid
knocking the main shaft.
5. 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.
6.6 BALANCE MODE SELECT
Press the corresponding
key to choose the balance mode. If all the lights not light up, it is the dynamic mode.
DYNAMIC—clip the weight on both sides of rim（dynamic balance test once start）
STATIC—Stick the weight in centre
MOT—optional for balancing the motorcycle
When balancing motorcycle wheels, you require the (optional) motorcycle adaptor accessory
MJ-II. With the assistance of the extension scale to measure Di, Br and Di. Input the measure

20
value into the Di, Br and Di display window. The input method is similar to the parameter input
of the car.
