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 goggles, safety glasses, or a face shield must be provided 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 operating. 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 qualified 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
current rating equal to or more than that of the
equipment 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 locations, or expose them to rain.
13. Avoid unintentional starting. Be sure the balancer
is turned off and power disconnected before servicing.
14. Disconnect the balancer before servicing.
15. Use only manufacturer’ s recommended accessories. Improper accessories may result in personal 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 machinery.
19. To reduce the risk of fire, do not operate equipment in the vicinity of open containers or flammable liquids (gasoline).

Owner’ s Responsibility
To maintain machine and user safety, the responsibility of the owner is to read and follow these instructions:
• 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 visible.
• Do not override safety features.
Operator Protective Equipment
Personal protective equipment helps make tire servicing 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 during 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 hearing protection if tire service activity is performed in an
enclosed area, or if noise levels are high.

Balancing Using Direct Select™
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 1 - 7 to balance the wheel, for measurement
and weight placement techniques. Refer to pages 8 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 Balancing
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 passenger 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 locations 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 (weight locations illuminate). At all locations, except T-2 Tape, place the corrective weight amount at top-dead-center. If the T2 Tape weight location is selected, the balancer activates its Laser Guided Operation™ feature (see page 6).
Static Balancing
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 selection of weights.
When in static mode,
the active Direct Select
Weight location is Clip
1 or T2 - Tape. Select
the weight location(s)
that best fits the rim configuration.
At the Clip 1 location, place the corrective weight
amount at top-dead-center. If the T2 - Tape weight location is selected, the balancer activates its Laser Guided
Operation™ feature (see page 6).
Note: If using a patch weight, refer to Patch Weight
Balance, page 13.
Special Balancing Modes
A special balancing mode is required for the following
methods.
EB (if available, model number supports EB) - 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 minimum amount
of corrective weight needed to bring dynamic imbalance within acceptable limits.
Balancing wheel assemblies using EB 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” necessary to achieve an
acceptable balance condition.
To enable the EB function, press and hold the SHIFT
key and press 0, then press 71 to toggle the EB mode
ON or OFF (software version 2.0.1.6 and forward). The
default is OFF.
For additional information, see Direct Select™ Weight
Placement Location on page 11.
Behind Spoke (T2 - Tape Mode Only) - Used to balance 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 (weight loca-
tions illuminate). When
the T2 - Tape weight location is selected, the balancer
activates its Laser Guided Operation™ feature (see
page 6).
Begin by following the Laser Guided Operation™ pro-
cedure, steps 1 through 4 on page 6.
1. When unbalance is displayed, rotate wheel until
inboard center bar blinks. Attach inboard corrective
weight at top-dead-center.
2. Next, rotate wheel until the outboard 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 outboard corrective weight location, as shown in figure 15.
4. Rotate the wheel toward front so the laser locator
dot is behind the first spoke; press SPOKE 1 (indicator
illuminates).
5. Rotate the wheel toward rear so the laser locator
dot is behind the second spoke; press SPOKE 2 (indicator illuminates). Now at the spoke 2 location, the
outboard center bar stops blinking and the two bars on
either side blink.
Note: The laser locator dot will stop blinking.
Figure 15 - Spoke 1 And Spoke 2 Locations On Either Side
Of Original Outboard Weight Location
6. Center and attach the spoke 2 outboard corrective
weight at the laser locator dot location (see figure 11
page 6).
7. Next, rotate the wheel toward the spoke 1 loca-
tion until the outboard 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 outboard corrective
weight at the laser locator dot location (see figure 11
page 6).
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 location 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 loosening of tire beads and the inflation of a
tire. Training is necessary in tire changer
operation and understanding the dangers
involved during bead seating and tire inflation 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 16, and enter
this diameter manually using the
keypad.
Figure 16 - Measure Outside Tire Diameter
3. Spin the wheel.
4. Rotate the wheel until the center weight position
bar blinks. Next, mark the tire and rim at 12 o’ clock.
Then remove the wheel assembly from the machine.
5. 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.
6. Complete by balancing the wheel assembly fol-
lowing normal procedures.

Mounting Wheel on Spindle
Shaft
Avoid back injury, seek assistance when lifting heavy tire/rim assemblies onto the 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 balancing. 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
centered 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 18 - 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 bubble 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
readings.
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
outboard 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 outboard 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 operation and understanding the dangers
involved during bead seating and tire inflation before attempting this stage of the
Match Balance procedure. Read the operators 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 outboard
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 topdead-center.
9. Press 4 on the control panel.
Weight amounts appear on the control panel. The
amount in the inboard weight display is the weight
imbalance for the rim. The amount in the outboard
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 outboard weight posi-
tion bar 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.
Training is necessary in tire changer operation and understanding the dangers
involved during bead seating and tire inflation before attempting this stage of the
Match Balance procedure. Read the operators manual supplied with the tire changer
and consult a supervisor.
12. Using a tire changer, rotate the tire until the mark
is aligned with the valve stem.
13. Remount the wheel assembly on the balancer.
14. Press NEXT or START to exit Match Balance. Select
a balancing mode and balance the wheel assembly.

Calibration
Machine Calibration
Important: Be sure to use the correct calibration
weight amount: a 4-ounce calibration weight in ounce
mode or a 100-gram calibration weight in gram mode
Important: Starting with software revision 2.0.1.9,
the factory default is set for a 4-ounce calibration
weight amount for both the ounce and the gram
weight measurement modes. Therefore, for Machine
Calibration, only the 4-ounce calibration weight is necessary regardless of the weight measurement mode
setting.
To use a 100-gram calibration weight amount, when
first prompted to use the 4-ounce weight in calibration
mode, press the gram/oz key (SHIFT 9) to toggle from
4.00 to 100. Once set, the balancer retains this new
default preference in memory.
Important: Starting with software revision 2.0.1.6,
the user is only required to enter the D dimension.
Note that prior software versions still require that the
user enter all the DIMS (A, W, and D wheel dimensions).
1. Mount a 16-inch steel tire/wheel assembly on the
balancer. A balanced tire/wheel is required.
Note: Position wheel so that no weights are on either
flange at the top-dead-center location. Turn the
machine OFF then ON.
2. Press and hold the SHIFT key and press 1 to select
the CAL MACHINE mode.
3. Enter the D dimension.
4. Lower the hood and press START.
5. After spin, raise the hood. Rotate wheel until the
outboard center bar blinks; attach calibration weight to
the outside flange at top-dead-center.
Figure 20 - Calibration Weight On Outside Flange At TopDead-Center
6. Lower the hood and press START.
Important: It is critical that the inner weight be
placed accurately to achieve proper calibration. If the
calibration weight is not moved from the outside
flange directly across to the inside flange, an inner
weight placement error will occur. To correct, follow
the information box instructions.
7. After spin, raise the hood. Rotate wheel until the
inboard center bar blinks; move and attach the calibration weight to the inside flange at top-dead-center.
Figure 21 - Calibration Weight Moved (Directly Across) To
Inside Flange
8. Lower the hood and press START.
9. Calibration complete. Press NEXT.
Arm Calibration
Important: Always perform the Arm Calibration
immediately after Machine Calibration. The balancer
software will not permit it otherwise.
During Machine Calibration, the balancer software
calculates both the A and W dimensions. The Arm
Calibration gives the balancer software a reference
point to the edge of the faceplate and home position.
When the user enters the A dimension from the arm
rod, it calculates the difference from the machine calibration A and uses that as a factor for the manual A
entry. Arm calibration also gives the D dimension a reference point from home position.
Note: Starting with software revision 3.0.0.0, CdE
will not appear in the INBOARD weight display and the
user is no longer required to enter the Code 96. Note
that prior software versions still require that the user
enter the Code 96 at the CdE prompt to access the
Arm Calibration mode.
1. Complete the Machine Calibration procedure (see
page 17).
2. Press and hold the SHIFT key and press 3 to select
the CAL ARM mode.
18 • Important: Always read and follow the information box instructions.
3. Bring the tip edge of the arm precisely to the outer
edge of the faceplate and hold it there while pressing
the NEXT key. (If necessary to reach the faceplate
accurately, loosen the calibration wheel temporarily.)
4. With the arm still at the edge of the faceplate,
enter the A dimension shown on the arm rod. Press
the NEXT key.

5. Move the arm to its home position and press the
NEXT key.
6. Move the arm to the clip-on weight location on the
rim flange and hold it there while manually entering the
D dimension. Press the NEXT key.
7. While still holding the arm at the clip-on weight
position on the wheel, enter the dimension read off
the arm rod. Press the NEXT key.
8. Return the arm to home position; calibration is
complete.
Important: To redo the Arm Calibration procedure,
press and hold SHIFT and press 0, then press 19 to
bypass the Machine Calibration requirement. Always
use the same wheel assembly that was used during
the machine calibration or else the calibration will not
be correct.
Maintenance Instructions
The balancer requires only minor maintenance to
keep the unit operating properly.
1. Keep the display clean and clear. Use a damp
cloth. Do not use cleaners or solvents which leave oily
or filmy residues behind.
2. Keep the adapters, cones, faceplate, threaded
shaft, pressure cup, and hub nut clean. Grease and dirt
buildup will cause inaccurate balancing and premature
wear. Clean these items at least once a day with a
vaporizing solvent.
3. Clean weight tray and any accessory posts, pegs,
or storage shelves with a vaporizing solvent. Weights
stored in a dirty tray may pick up grease and dirt which
may keep them from securely attaching to the wheel.
Use common sense, this is an electrical
device. Exposing the balancer to water,
either by hose or bucket, or by exposure to
rain or snow, may cause risk of shock or
electrocution to operator or bystanders.
Place, store, and operate the balancer only
in a dry, sheltered location.
Do not hose down with water or bucket
wash the balancer. Extensive damage to the
balancer will result. Sensitive electronic
components, wiring harnesses, and other
devices housed in the balancer are not
intended to be exposed to water.
4. Keep the area around and under the balancer
clear. Remove any tools or other items that are leaning
against the balancer. Remove any items that may
cause the balancer to not sit level. Be particularly cautious of new or used wheel weights on the floor, as
they may cause personal injury due to falls.
5. Use only COATS
®
accessories. Accessories from
other manufacturers may not fit or function properly,
and may damage the balancer.
6. To replace Arm Laser battery, remove cover (fig.

Diagnostic Procedures
After Balance Vibration Problems
If vibration is still present after balancing the wheels
and driving the vehicle on smooth pavement, remove
the wheels and recheck the balance. If a wheel is out
of balance the cause maybe:
• Wheel was not mounted/centered correctly on the
balancer.
• A weight has come off the wheel (possibly the
wrong clip style). Remove the other weights from
the wheel and rebalance.
• Foreign material inside the tire. Remove the tire
from the wheel, remove the foreign material, and
remount. Remove wheel weights and rebalance
the wheel.
• Stones or other foreign objects caught in the tire
tread or rim. Remove the objects. Check and rebalance if needed.
If the balancer still indicates the wheels are balanced
to within 0.05 ounces on both inner and outer displays,
the problem is not in the balance of the wheels. Check
the following possible sources of vibration:
• Tire pressure. Bring all tires up to the recommended PSI.
• Radial or lateral runout in the tire or wheel. Replace
the damaged part.
• Unbalance in wheel covers or trim rings. Remove
the wheel covers or trim rings and test drive. If the
vibration is gone, remove the shaft and use an
appropriate adapter to mount the wheel to the balancer. Balance the wheel with the wheel cover or
trim ring attached to the wheel.
• Incorrectly mounted tire and wheel. Remount correctly.
• Damaged wheel bolt holes. Replace wheel.
• Worn universal joints. Replace as required.
• Drive shaft unbalance or damaged. Balance, repair,
or replace.
• Unbalance in brake rotor(s) or drum(s).
• Suspension out of alignment. Align the vehicle and
replace any damaged or worn parts.

as noted below.
A factory trained COATS®Service Technician must
perform the install, setup, and initial test procedures
on your wheel balancer. Do not attempt to install and
setup the unit yourself. Accurate and reliable operation
of your unit depends on proper installation. Please contact COATS®directly at 1-800-688-9240 for the
Certified Service Partner nearest you.
Connect to Power
Your factory trained COATS®Service Technician
should do the final check to verify the power installation before connecting the balancer to a power supply.
Failure due to improper power connection may void
the warranty.
Floor and Space Requirements
The balancer must be located on a flat floor of solid
construction, preferably concrete. The balancer must
sit solidly on its three feet. If the balancer is not level,
does not sit solidly on its three feet, or is placed on an
unstable floor, the balancer will not function properly
and may produce inaccurate balance readings.
Do not operate the balancer while it is on the pallet.
Select a location for the balancer that provides a
level, solid floor, and adequate clearance around and
above the balancer. Make sure the location selected
has enough room above and behind the unit so the
hood can be raised completely. The location must also
provide working room for mounting and removing
wheels. Make sure the area has adequate lighting.
