READ ALL INSTRUCTIONS
1. Eye and face protection recommendations:
“Protective eye and face equipment is required to
be used where there is a reasonable probability of
injury that can be prevented by the use of such
equipment.” O.S.H.A. 1910.133(a) Protective gog-
gles, safety glasses, or a face shield must be pro-
vided by the owner and worn by the operator of
the equipment. Care should be taken to see that
all eye and face safety precautions are followed by
the operator. ALWAYS WEAR SAFETY GLASSES.
Everyday glasses only have impact resistant
lenses, they are not safety glasses.
2. Be sure that wheels are mounted properly, the hub
nut engages the arbor for not less than four (4)
turns, and the hub nut is firmly tightened before
spinning the wheel.
3. Read and understand this manual before operat-
ing. Abuse and misuse will shorten the functional
life.
4. Be sure the balancer is properly connected to the
power supply and electrically grounded.
5. Do not operate equipment with a damaged cord or
if the equipment has been dropped or damaged –
until it has been examined and repaired by a quali-
fied serviceman.
6. Do not let cord hang over edge of table, bench, or
counter or come in contact with hot manifolds or
moving fan blades.
7. If an extension cord is necessary, a cord with a cur-
rent rating equal to or more than that of the equip-
ment should be used. Cords rated for less current
than the equipment may overheat. Care should be
taken to arrange the cord so that it will not be
tripped over or pulled.
8. Keep guards and safety features in place and in
working order.
9. Wear proper clothing. Safety toe, non-slip
footwear and protective hair covering to contain
hair is recommended. Do not wear jewelry, loose
clothing, neckties, or gloves when operating the
balancer.
10. Keep work area clean and well lighted. Cluttered
and/or dark areas invite accidents.
11. Avoid dangerous environments. Do not use power
tools or electrical equipment in damp or wet loca-
tions, or expose them to rain.
12. Avoid unintentional starting. Be sure the balancer
is turned off and power disconnected before serv-
icing.
13. Disconnect the balancer before servicing.
14. Use only manufacturer’s recommended acces-
sories. Improper accessories may result in per-
sonal injury or property damage.
15. Repair or replace any part that is damaged or worn
and that may cause unsafe balancer operation. Do
not operate damaged equipment until it has been
examined by a qualified service technician.
16. Never overload or stand on the weight tray or any
part of the balancer.
17. Do not allow untrained persons to operate machin-
ery.
18. To reduce the risk of fire, do not operate equip-
ment in the vicinity of open containers or flamma-
ble liquids (gasoline).
19. Adequate ventilation should be provided when
working on or operating internal combustion
engines.
20. Keep hair, loose clothing, fingers, and all parts of
body away from moving parts.

Important: Always read and follow the instructions. • v
Owner’s Responsibility
To maintain machine and user safety, the responsibil-
ity of the owner is to read and follow these instruc-
tions:
• Follow all installation instructions.
• Make sure installation conforms to all applicable
Local, State, and Federal Codes, Rules, and
Regulations; such as State and Federal OSHA
Regulations and Electrical Codes.
• Carefully check the unit for correct initial function.
• Read and follow the safety instructions. Keep them
readily available for machine operators.
• Make certain all operators are properly trained,
know how to safely and correctly operate the unit,
and are properly supervised.
• Allow unit operation only with all parts in place and
operating safely.
• Carefully inspect the unit on a regular basis and
perform all maintenance as required.
• Service and maintain the unit only with authorized
or approved replacement parts.
• Keep all instructions permanently with the unit and
all decals/labels/notices on the unit clean and visi-
ble.
• Do not override safety features.
Operator Protective Equipment
Personal protective equipment helps make tire serv-
icing safer. However, equipment does not take the
place of safe operating practices. Always wear durable
work clothing during tire service activity. Loose fitting
clothing should be avoided. Tight fitting leather gloves
are recommended to protect operator’s hands when
handling worn tires and wheels. Sturdy leather work
shoes with steel toes and oil resistant soles should be
used by tire service personnel to help prevent injury in
typical shop activities. Eye protection is essential dur-
ing tire service activity. Safety glasses with side
shields, goggles, or face shields are acceptable. Back
belts provide support during lifting activities and are
also helpful in providing operator protection.
Consideration should also be given to the use of hear-
ing protection if tire service activity is performed in an
enclosed area, or if noise levels are high.

Operating the Balancer
Mounting Wheel on Balancer Shaft
Select the most appropriate mounting method for the
wheel you are balancing. Using the proper method
ensures secure mounting and safe balancer operation,
and prevents damage to the wheel.
On most wheels, the inner side of the wheel hub
usually has the most uniform surface for wheel bal-
ancing. Always center the wheel by the most uniform
shaped side of the hub to achieve the most accurate
balance.
Regardless of mounting type, always make sure that
the wheel is forced firmly against the shaft faceplate
and that the hub nut engages the threaded shaft for at
least four complete turns. To assist in centering the
wheel properly, rotate the wheel and the shaft while
tightening the hub nut.
Failure to tighten the hub nut properly may
result in the wheel dismounting, causing
personal injury and property damage.
Standard Back Cone/Collet Mounting
Most original equipment and steel wheels can be
mounted properly using this method. The wheel is cen-
tered on a cone from the inner side of the hub.
1. Select the cone/collet that best fits the center hole
in the wheel. Slide the cone/collet onto the shaft with
the large end towards the cone spring.
2. Lift wheel onto the shaft and center it on the
cone/collet.
3. Attach the pressure cup to the hub nut.Install
the Hub nut assembly onto the shaft and tighten
it securely against the wheel. The wheel must be
forced firmly against the faceplate. The hub nut
must engage the threads for at least four full
turns.
Note: Use a nylon spacer (protective ring) to protect
cus-tom wheel finishes.
Note: If the hub nut will not tighten completely, use
the front cone mounting method.

Optional Front Cone/Collet Mounting
A wheel should be centered by the outer side of the
hub only when the inner surface will not provide an
accurate surface to center on.
1. Select the cone that best fits the center hole in the
wheel.
2. Lift the wheel onto the shaft and slide it back
against the shaft faceplate.
3. Slide the cone onto the shaft and into the center
of the wheel. You will need to lift the tire to seat the
cone in the center hole.
4. Install the hub nut (without pressure cup) onto the
shaft. Tighten it securely against the cone. The hub nut
must engage the threads for at least four full turns.
Note: If the hub nut will not tighten completely
because of a lack of threads, use an additional cone as
a spacer between the mounting cone and the hub nut.
The wheel must be forced firmly against the faceplate.
Note: Do not front cone chrome or clad wheels.

permit the hub nut to engage at least four turns of the
shaft, this alternate method should be used.
1. Place the cone spring onto the balancer shaft with
the large end towards the faceplate.
2. Select the cone/collet that best fits the center hole
in the wheel. Slide the cone/collet onto the shaft with
the large end towards the faceplate.
3. Lift wheel onto the shaft and center it on the cone/
collet.
4. Use the small nylon spacer (no-mar ring) or a cen-
tering cone/collet to press against the outer wheel hub.

HIDE THE ADHESIVE WEIGHTS (Behind Spoke)
Behind Spoke is only possible in the event of static unbalance or ALU external side and is used to hide any
adhesive weights correcting unbalance behind the rim spokes.
.
1. Perform an unbalance measurement spin.
2. Position the static unbalance or outside ALU in the correction position
3. Bring one of the spoke at 12 o’clock and press
4. Turn the wheel in the unbalance rotation direction indicated on the display until the second spoke is at
12o’clock and press the button.
5. Now, turn the wheel to the correction positions indicated by the LEDs and correct the value displayed.
The Autolock function should lock 2 the two locations for correct weights. To return to the normal unbalance
indication, press
AUTOMATIC MINIMIZATION OF STATIC UNBALANCE
This program is designed to improve the quality of balancing without any mental effort or loss of time by the operator.
In fact by using the normal commercially available weights, with pitch of 5in every 5g, and by applying the two
counterweights,which a conventional wheel balancer rounds to the nearest value, there could be a residual static
unbalance of up to 4 g. The damage of such approximation is emphasized by the fact that static unbalance is cause of
most of disturbances on the vehicle. This new function, resident in the machine, automatically
indicates the optimum entity of the weights to be applied by approximating them in an “intelligent” way
according to their position in order to minimize residual static unbalance.
Set the first split unbalance to correction position 1
