IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
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. Do not disable hood safety interlock system, or in
any way shortcut safety controls and operations.
3. 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.
4. Read and understand this manual before operat-
ing. Abuse and misuse will shorten the functional
life.
5. Be sure the balancer is properly connected to the
power supply and electrically grounded.
6. 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.
7. Do not let cord hang over edge of table, bench, or
counter or come in contact with hot manifolds or
moving fan blades.
8. 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.
9. Keep guards and safety features in place and in
working order.
10. 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.
11. Keep work area clean and well lighted. Cluttered
and/or dark areas invite accidents.
12. Avoid dangerous environments. Do not use power
tools or electrical equipment in damp or wet loca-
tions, or expose them to rain.
13. Avoid unintentional starting. Be sure the balancer
is turned off and power disconnected before serv-
icing.
14. Disconnect the balancer before servicing.
15. Use only manufacturer’s recommended acces-
sories. Improper accessories may result in per-
sonal injury or property damage.
16. 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.
17. Never overload or stand on the weight tray or any
part of the balancer.
18. Do not allow untrained persons to operate machin-
ery.
19. To reduce the risk of fire, do not operate equip-
ment in the vicinity of open containers or flamma-
ble liquids (gasoline).
20. Adequate ventilation should be provided when
working on or operating internal combustion
engines.
21. Keep hair, loose clothing, fingers, and all parts of
body away from moving parts.
22. Use equipment only as described in this manual.
23. Use only manufacturer’s recommended attach-
ments and accessories.

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.

Balancing Modes
A variety of wheel configurations can be balanced
using this wheel balancer. Read through this section, it
will help in determining which mode and options are
best suited for certain wheel assemblies. Refer to
pages 2 - 8 to balance the wheel, for measurement,
and, weight placement techniques. Refer to pages 9 -
11 for Control Panel functions.
Remember: As with any balancing procedure, first
remove any weights attached to the wheel, inspect the
tire and wheel, and use the most appropriate balancer
mounting method before beginning.
Dynamic Modes
Choose a dynamic balance to balance a wheel using
two planes for correction. Direct Select™ the weight
option that best fits the available weight locations.
Clip-on Weights - The default; used for most pas-
senger and light truck tire assemblies using the most
common location for corrective weights. Clip-on
weights are placed on the inner and outer rim flanges.
Have the following items handy: appropriate style
clip-on weights.
Direct Select Weight position Clip 1
and Clip 2 (weight LEDs illuminate). At
these locations place the corrective
weight amount at top-dead-center.
Tape-A-Weights®and Hidden Tape-A-Weights®-
Used when one or both clip-on weight locations are
not possible or desired. Select the weight location(s)
that best fits the rim configuration.
Have the following items handy: appropriate style
clip-on weights and Tape-A-Weights™.
Direct Select Weight position Clip 1 or T1 - Tape and
T2 - Tape, T3 - Tape or Clip 2 (LEDs illuminate). At all
locations, except T-2 Tape, place the corrective weight
amount at top-dead-center. If the T2 - Tape weight loca-
tion is selected, the balancer activates its Laser Guided
Operation™ feature (see page 7).
Static Modes
Choose a static balance for wheel assemblies that
are not possible to balance dynamically or for narrow
wheels. For example, a motorcycle wheel that has a
small wheel width.
Have the following items handy: an appropriate
wheel assembly mounted on the balancer and a selec-
tion of weights.
When in static mode,
the only active Direct
Select Weight location
is Clip 1 or T2 - Tape.
Select the weight location(s) that best fits the rim con-
figuration.
At the Clip 1 location, place the corrective weight
amount at top-dead-center. If the T2 - Tape weight loca-
tion is selected, the balancer activates its Laser Guided
Operation™ feature (see page 7).
EconoBalance™ Mode
EconoBalance is an alternate approach to balancing a
tire and wheel assembly. The technology seeks first to
eliminate the static imbalance in a wheel assembly
then, based on several parameters, calculates the min-
imum amount of corrective weight needed to bring
dynamic imbalance within acceptable limits.
Balancing wheel assemblies using EconoBalance
often results in the application of less corrective
weight. In addition to the potential direct savings in
wheel weights, there is a potential productivity savings
due to a reduction in the number of “re-spins” neces-
sary to achieve an acceptable balance condition.
For additional information, see Balance Options on
page 11.
Special Modes
Choose a special mode option for the following spe-
cial type wheel assemblies.
Behind Spoke (T2 - Tape Mode Only) - Used to bal-
ance with two adhesive weights located behind the
spokes in the outer correction plane.
Only use the Direct
Select Weight position
Clip 1 or T1 - Tape and
T2 - Tape (LEDs illumi-
nate). When the T2 -
Tape weight location is selected, the balancer activates
its Laser Guided Operation™ feature (see page 7).

Important: Always read and follow the information box instructions. • 13
Begin by following the Laser Guided Operation™ pro-
cedure, steps 1 through 4 on page 7.
1. When the unbalance is displayed, rotate the wheel
until the left plane center bar blinks. Attach the left
plane corrective weight at top-dead-center.
2. Next, rotate the wheel until the right plane center
bar blinks and the two bars on either side blink.
Note: The laser locator dot will stop blinking.
3. Select the BEHIND SPOKE mode option.
Important: Be sure that the Spoke 1 and Spoke 2
locations are on either side of the original right plane
corrective weight location, as shown in figure 14.
4. Rotate the wheel toward front so the laser locator
dot is behind the first spoke; press SPOKE 1 (LED illu-
minates).
5. Rotate the wheel toward rear so the laser locator
dot is behind the second spoke; press SPOKE 2 (LED
illuminates). Now at the spoke 2 location, the right
plane center bar stops blinking and the two bars on
either side blink.
Note: The laser locator dot will stop blinking.

Original Right Plane Weight Location
6. Center and attach the spoke 2 right plane correc-
tive weight at the laser locator dot location (see figure
10 page 7).
7. Next, rotate the wheel toward the spoke 1 location
until the right plane center bar stops blinking and the
two bars on either side blink.
Note: The laser locator dot will stop blinking.
8. Center and attach the spoke 1 right plane correc-
tive weight at the laser locator dot location (see figure
10 page 7).
9. Respin tire/wheel to check balance.
Patch Weight Balance - Use a static patch weight bal-
ance when there is a very large unbalance in a tire
assembly or if a very large tire has a large unbalance. A
weighted balance pad (patch weight) is placed inside the
tire in the center to compensate for the large unbalance.
Direct Select Weight position Patch
Static (weight LED illuminates). At this
location place the corrective weight
amount at top-dead-center.
Have the following items handy: measuring tape and
various patch weight sizes.
Note: Before proceeding with Patch Weight Balance,
it is recommended that you use the Match Balance
(Optimization) procedure first, see page 16, in order to
use the smallest patch weight.
The Patch Weight Balance involves the loos-
ening of tire beads and the inflation of a tire.
Training is necessary in tire changer opera-
tion and understanding the dangers
involved during bead seating and tire infla-
tion before attempting this stage of the
Patch Weight Balance procedure. Read the
operators manual supplied with the tire
changer and consult a supervisor.
The patch weight balance steps are as follows:
1. Direct Select Weight position PATCH STATIC. The
balancer automatically sets itself for a STATIC balance.
2. Measure the outside tire
diameter, see figure 15, and enter
this diameter manually using the
keypad.

3. Move the offset arm tip to the inside of rim to set
weight location. Wait for beep.
4. Spin the wheel.
5. Rotate the wheel until the center weight position
LED bar is blinks. Next, mark the tire and rim at 12
o’clock. Then remove the wheel assembly from the
machine.
6. Disassemble the tire and rim. Place patch weight
in the tire at location marked on the tire. Reassemble
tire and rim matching the marks on the tire and rim.
7. Complete by balancing the wheel assembly fol-
lowing normal procedures.

Mounting Wheel on Spindle
Shaft
Avoid back injury, seek assistance when lift-
ing heavy tire/rim assemblies onto the bal-
ancer 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.
Standard Back Cone 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. Place the cone spring onto the shaft with the large
end towards the faceplate.
2. Select the cone that best fits the center hole in the
wheel. Slide the cone onto the shaft with the large end
towards the cone spring.
3. Lift the wheel onto the shaft and center it on the
cone.
4. Attach the pressure cup to the hub nut and install
the assembly onto the shaft. Tighten securely.

Standard Front Cone 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.
Figure 17 - Front Cone Mounting
Alternate Mounting
If the wheel has a protruding outer hub which will not
permit the use of the pressure cup, or the cup will not
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 shaft with the large
end towards the faceplate.
2. Select the cone that best fits the center hole in the
wheel. Slide the cone onto the shaft with the large end
towards the cone spring.
3. Lift the wheel onto the shaft and center it on the
cone.
4. Use the small nylon spacer (no-mar ring) or a cen-
tering cone to press against the outer wheel hub.
5. Install the hub nut (without the pressure cup) onto
the shaft. Tighten securely.

Match Balance (Optimization)
The Match Balance (Tire/Rim Weight Optimization)
procedure is used to determine the best mating of tire
and rim that will result in the least amount of total
unbalance of the assembly. It requires two spins and
two rotations of the tire on the rim. Match Balance
may be needed when:
• The customer complains of ride problems.
• The balancer calls for Total Static weights in excess
of 3 ounces (85 grams) on passenger car tires.
Note: A high unbalance may indicate the improper
mounting of the assembly on the balancer, or a rim
that is out of round or misformed, or a tire with a bub-
ble or other problem. If the unbalance is excessive, it
may be prudent to replace the rim, the tire, or both. If
either is replaced, do not continue with Match Balance.
Balance the new tire and rim and evaluate the read-
ings.
Match Balance Mode
If you choose to use Match Balance to correct for a
condition, such as a large static unbalance, then follow
the information box instructions for the MATCH
BALANCE procedure as outlined in the following
steps.
Note: Use this procedure only after the wheel has
spun and the corrective weight amount is displayed.
Note: Use the total static display option. See BAL-
ANCE OPTIONS, page 11, for further details.
1. Press and hold the SHIFT key and press 5 to select
the Match Balance mode. A “1” will appear in the right
plane weight display.
2. Raise the hood and rotate the wheel until the valve
stem is at top-dead-center. Mark the tire sidewall at
the valve stem.
3. Press 1 on the control panel; a “2” will appear in
the right plane weight display.
4. Remove the wheel assembly from the balancer.
The Match Balance involves the loosening
of tire beads and the inflation of a tire.
Training is necessary in tire changer opera-
tion and understanding the dangers
involved during bead seating and tire infla-
tion before attempting this stage of the
Match Balance procedure. Read the opera-
tors manual supplied with the tire changer
and consult a supervisor.
5. Using a tire changer, rotate the tire 180 degrees on
the rim.
6. Remount wheel assembly on the balancer. Press 2
on the control panel; a “3” will appear in the right plane
weight display.
7. Lower the hood and press START. The wheel spins.
8. When the wheel stops spinning, raise the hood
and rotate the wheel until the valve stem is at top-
dead-center.
9. Press 4 on the control panel.
Weight amounts appear on the control panel. The
amount in the left plane weight display is the weight
imbalance for the rim. The amount in the right plane
weight display is the weight imbalance for the tire. Use
these weight amounts to determine the suitability of
the rim or tire.
Note: If either the rim or the tire weight amount is
close to zero or zero then using Match Balance will not
affect the total unbalance of the assembly.
10. Rotate the wheel until the right weight position
LED flashes. Mark the tire at top-dead-center.
11. Remove wheel assembly from balancer.
The Match Balance involves the loosening
of tire beads and the inflation of a tire.
