1.4.Ready to balance a wheel
NOTE: Calibration is required when the wheel balancer is first put into
operation at a fixed location, after it is moved to a new location or when
the technician suspects the machine of providing incorrect values or
when main components have been replaced. It is recommended to
perform a calibration every 3 month, but especially while having
enormous possible changes of temperature during the seasons. See the
detail procedure in the calibration section.
1.4.1. MOUNTING A WHEEL ONTO THE SPIN SHAFT
Select the correct size centering-cone diameter
that will ensure the wheel rim is tightly secured
(no wobble) to the thread shaft. Insert the
centering-cone to the spin shaft and partially
through the center hole of the rim. Please pay
attention use cones and quick hub wing nut in the
different fields of application!
Below are some of the different methods for the
quick hub wing nut wheel mounting, choose the
proper one in your
application.
1.4.2. BACK CENTERING-CONE MOUNTING
Most of original equipment rims and steel rims can be handled by
using this procedure. The wheel is back-cone-centered, centering-
cone from the INNER side of the hub.

www.astontechusa.com
10
Aston Magnetic Levitation Wheel Balancer AWB-139ML User’s Manual
1）Make sure the pressure cup is attached to the quick hub wing
nut.
2）Select the centering-cone that best fits the center hole in the
rim. Slide the centering-cone over the thread shaft with the
larger diameter towards the flange, small diameter joining the
center hole of the rim.
3）Lift the wheel onto the thread shaft and center it onto the
centering-cone. Make sure to position the INNER side of the
wheel rim against the flange and cone.
4）Mount the quick hub wing nut with pressure cup onto the
thread of the spin shaft and tighten it firmly against the rim.
The quick hub wing nut should engage the threads for at least
three full turns.
NOTE ： Use the nylon spacer between rim and pressure
cup to protect custom wheel finishes.
1.4.3. FRONT CENTERING-CONE MOUNTING
A wheel should only be centered with this method when the
type of the INNER surface of the rim is not convenient to
provide an accurate centering seat.
1）Make sure the pressure cup is NOT attached to the
quick hub wing nut.
2）Lift the wheel onto the threaded spin shaft and slide it
back against the shaft flange. Make sure to position the
INNER side of the wheel rim against the flange.
3）Slide the centering-cone onto the shaft into the middle of the
wheel rim. It is necessary to lift the wheel to get the centering-
cone placed in the center hole.
4）Fit the quick hub wing nut without pressure cup onto
the spin shaft. Tighten it securely against the centering-
cone. The hub wing nut must engage the threads for at
least three full turns.

STEP 3: Press the SPL key, the wheel rotates slowly, the OUTER (right) weight positioning
bars are fully illuminated OUTER as the wheel stop at the (right) correction weight
position OUTER (TDC of the rim).
STEP 4: Apply a balancing weight with displayed amount to the OUTER (right) plane in the
position onto the rim at TDC (12 o'clock).
（SPL might locate at a position very close to TDC due to wheel weight deviation. Slightly rotate
the wheel forwards or rearwards until you get the buzzer sound.）
Press key C to exit the SPL program.
E After balance weights applied on the wheel, lower the protection hood, and proceed a test
wheel spin to check the balancing result. The result shall be zero on both weight display
windows if correct weights are applied to the correct positions.
Press <T Key to read the precise unbalance value.
**************************************************************************************
➢During applying weights to verify the wheel balance, positioning error might happen, and
a few degrees error might cause a residual unbalance as large as 5-10 grams, especially in
case of large unbalance.
➢In practical wheel balancing operations, available counter weights are 5 grams
increments, i.e. 5, 10, 15...60 grams etc. However, an actual unbalance results might be
any grams in between, for example, when there is a 23 grams unbalance in actual, and the
program will suggest 25 grams to balance it.

www.astontechusa.com
18
Aston Magnetic Levitation Wheel Balancer AWB-139ML User’s Manual
➢The facts described above might cause an unsatisfied balancing result, if such cases happen,
it is recommended to remove the applied weights from the rim and redo the balancing.
Always check if the balancing weights (clip-on or stick-on weights) are securely applied onto
the rim. A weight not fitted securely might come off as the wheel rotates and causes dangers.
**************************************************************************************
1.6.2 Standard ALU Programs
With the rated wheel data A, W and D entered, there are 5 standard ALU modes rated available,
the different possibilities of weight application have been considered. All standard ALU
programs provide correct unbalance values while maintaining the rated geometric data A, W
and D setting of the alloy wheel.
STANDARD ALU Programs

balancing.
STEP 3: Search weight as per the procedures described in the section of standard dynamic
balancing.
STEP 4: Apply balancing weights as per the selected ALU program illustrated.
STEP 5: Proceed a test spin to check the balancing correction result
⚫Laser pointer for ALU-1
For the models with laser pointer, ALU-1 program will relocate the
weight form top position (12 o’clock) to bottom position (6
o’clock). As the weight point reaches to the correction angular
position, the laser light will project on the wheel, where indicates
the correction weight to be stick on.
******************************************************************************
Some slight residual unbalances may remain at the end of the test spin due to the considerable
difference in shape that may be found on rims with same rated dimensions. Therefore, if the
standard ALU programs are not giving a satisfied balancing result, choose the variable plane
program ALU-S to have correct balancing.
******************************************************************************
1.6.3 ALU-S Program (VARIABLE PLANE PROGRAM)
This program makes it possible to apply adhesive weights in
user selected positions. It is used for maximum precision
balancing of light alloy rims that require both weights for inner
and outer planes to be applied on the inside surface of the rim.
Press ALU keys enter the programs until the light over the mark "ALU-S" illuminates, as illustrated,
3 lights on the balancing mode indicator are illuminated.
⚫WHEEL GEOMETRIC DATA ACQUISITION
Geometric data relating to the actual balancing planes rather than the rated wheel data (A, W and D
as in standard dynamic and standard ALU programs) must be entered. The balancing planes where
the adhesive weights are to be applied may be selected by user according to the specific shape of
the rim.
