IMPORTANT SAFETY 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.
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).
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.

Owner’s Responsibility
To maintain machine and user safety, the responsibility
of the owner is to read and follow these instructions:
Definitions of Hazard Levels
Identify the hazard levels used in this manual with the
following definitions and signal words:
• 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.

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.

Set-up Instructions
Receiving
The shipment should be thoroughly inspected as soon
as it is received. The signed bill of lading is acknowledgement, for the carrier, of receipt in good condition
of the shipment covered by our invoice.
If any of the goods called for on this bill of lading are
shorted or damaged, do not accept them until the carrier makes a notation of the shorted or damaged goods
on the freight bill. Do this for your own protection.
NOTIFY THE CARRIER AT ONCE if any hidden loss or
damage is discovered after receipt and request him to
make an inspection. If the carrier will not do so, prepare
an affidavit to the effect that you have so notified the
carrier (on a certain date) and that he has failed to
comply with your request.
IT IS DIFFICULT TO COLLECT FOR LOSS OR DAMAGE AFTER YOU HAVE GIVEN THE CARRIER A CLEAR
RECEIPT.
File your claim with the carrier promptly. Support
your claim with copies of the bill of lading, freight bill,
invoice, and photographs, if possible.
Electrical Requirements
See serial tag for the appropriate power requirements
of your machine.
Always have a qualified electrician install the proper
receptacles in accordance with state and local codes.
Air Supply Connection
The wheel balancer requires a minimum 8 CFM clean/
dry air source at 115 PSI. This system is only intended
for operation of the spindle with pneumatic locking. The
connection fitting is located at the back of the machine.
At least 8 Kg/cm2 (~ 0.8 MPa; ~ 8 BAR; ~ 115 PSI)
pressure is needed for correct operation of the release
device.
Although COATS responsibility ceases upon delivery
of the shipment to the carrier, we will gladly assist
in tracing lost shipments. Our willingness to assist in
every possible manner does not make COATS responsible for collection of claims, or replacement of lost or
damaged materials.
2 • Important: Always read and follow instructions.

Machine Set-up
CAUTION
Do not use the control panel, control panel
base, accessory storage, faceplate, hood or
shaft to lift the balancer.
CAUTION
Do not attempt to install and set-up the unit
yourself. Contact COATS as noted below.
A factory trained COATS Service Technician must perform the install, set-up, 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.
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.

Using The Offset Arm
Use the offset arm gauge to automatically measure
the distance from wheel to machine and the wheel
diameter at the point of weight application. Also, use
the offset arm for the correct positioning of weight
application on the inside rim as indicated by the balancer instructions. When not in use or when prompted
by the balancer instructions, store the offset arm in the
home position as shown in figure 5.
Using The Laser Locator
If a hidden weight (Tape-A-Weight®) location is
selected, use the laser locator (figure 5) to point to the
hidden weight location.
If, due to a fault in the machine, the wheel keeps
spinning permanently, switch off the machine at the
master switch or by unplugging the plug from the
power supply. Wait until the wheel stops, or actuate the
positioning pedal before opening the wheel guard.
Positioning Pedal
In the standard version, the pedal controls a mechanical brake which facilitates positioning and holding the
wheel in place for corrective weight application.
In the pneumatic version, the pedal engages/releases
the pneumatic sleeve. The pedal has two positions: the
upper position releases the pneumatic sleeve; the lower
position engages the pneumatic sleeve to mount the
wheel onto the pneumatic shaft.
Auto Wheel Lock Feature (PL Version Only)
Once the assembly is rotated to the weight application
position, it will lock in place to assist in weight placement. Simply apply additional force and the lock will
release to allow movement to the next weight position.
Note: For best performance, choose an outboard
weight position as deep into the rim as wheel allows.

Mounting Wheel On 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, on standard units,
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.

Setting Wheel Dimensions (DIM)
Wheel Data Entry
Before a wheel can be balanced, wheel dimensions
must be entered into the computer.
Definition of Dimensions (DIM)
W = Width
The width of the wheel at the rim flanges, measured
with the calipers or width sonar as shown in figure 17.
D = Diameter
The diameter of the wheel as indicated on the tire.
A = Offset
The distance measured from the balancer (“0” on offset arm) to inner plane of the rim (inner weight location).
1. To automatically enter A & D dimensions, pull the
offset arm out and up against the wheel at the appropriate weight placement location; hold it still and wait for
the deep or the display to change.
Figure 13- Dimensions Screen
Note: When the offset arm is pulled out from home
position, the dimensions screen is automatically
selected.
Figure 11 - W, D, and A Tire Dimensions
Note: Only use calipers provided by the wheel bal-
ancer manufacturer because others may not be the
same.
Note: A thick flange, on some aluminum wheels, can
effect the measured diameter. For example, a 16-inch
rim can have a measured diameter of 15.5-inches.
A2 = Offset
The distance measured from the balancer (“0” on
offset arm) to outer plane of the rim (outer weight location). Used only for adhesive weight location.
D2 = Diameter
The diameter as measured at the A2 weight location.
Used only for adhesive weight location.
Note: If the acoustic signal is enabled, the acquisition
of the dimensions is accompanied by a BEEP.
Note: When the computer acquires the wheel dimen-
sions it is indicated by the correction weight symbol,
which changes from blue to red.
Automatic A & D Measurement Methods:
• For Clip 1 data entry, move the arm from home posi-
tion and place the offset arm up against the wheel
flange in either position 1 or 2, as shown in figure 14.

Balancing A Wheel
A variety of wheel configurations can be balanced
using this wheel balancer. Read through this section,
it will help in determining which balancing options are
best suited for certain wheel assemblies.
Dynamic Balancing
Choose a dynamic balance to balance a wheel using
two planes for correction. Select the weight option that
best fits the available weight locations on the rim.
Clip-on Weights - The standard default; used for most
passenger tire/wheel assemblies using the most common location for corrective weights. Clip-on weights
are placed on the inner (inboard) and outer (outboard)
rim flanges.
Static Balancing
Choose a static balance to balance a wheel using one
plane for correction. Place the single corrective weight
at top-dead-center (12 o’clock) on either flange, at the
center of the rim channel, placed inward either side, or
split on either sides.
ALUS (Aluminum Wheels) - To balance aluminium
wheels you usually use a self-adhesive weight location
that is positioned differently from the clip-on weight
position(s) used in standard balancing. Be sure to use
the appropriate wheel data entry method since the
balancer calculates out of balance values based on the
wheel dimension measurements (DIM) entered for the
tire/wheel assembly.
Figure 16 - Dynamic Balance Weight Locations
Note: When the machine is switched on, a standard
dynamic balance using clip-on weight locations is the
default setting.
Figure 17 - Static Balance Weight Locations
Note: When in static mode, you only need to input the
DIAMETER wheel measurement.
Important: If you decide to use the rim channel for
corrective weight placement, remember you may need
to adjust the DIAMETER measurement input. Typically
you would make it 2 or 3 inches less than the actual tire/
wheel diameter.
18 • Important: Always read and follow instructions.

weight locations. Arrows appear that are useful for positioning the corrective weight at the application point.
If the out-of-balance is less than the chosen threshold
value, - - - appears instead of the out-of-balance value
to indicate, on that particular side, that the wheel is in
tolerance.

Match Balance (Optimization)
WARNING
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.
Match Balance (Optimization)
The symbol is displayed automatically for static
out of balance exceeding 30 grams (1.1 oz.)
Use the Match Balance (Tire/Rim Weight Optimization) program to determine the best mating of tire and
rim that will result in the least amount of total out of
balance of the assembly. It requires two spins and two
rotations of the tire on the rim. Match Balance may be
needed when:
Important: A high out of balance 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 out of balance 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.
If you choose to use Match Balance to correct for a
condition, such as a large static out of balance, then
follow the on-screen 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: Presetting of tolerance on the machine. There is
no general rule concerning acceptability of a Max True
Runout Limit (see Balancing Set-up) value. As a first
approximation we consider it correct to use a threshold
of 1 to 1.5 mm.
The much enlarged figures show the outer tire surface
and axis of wheel rotation.

• The customer complains of ride problems.
• The balancer calculates a high out of balance.
• The balancer calls for Total Static weights in excess

Press + and follow the on-screen
instructions.
Figure 24 - Runout Measurements
Fig. A - shows measurement of the total Peak-to-Peak
runout defined as maximum radial deviation of the tire
surface.
Fig. B - shows measurement of the runout of the
1st harmonic, i.e. the eccentricity of that circle which
“recopies” the tire shape, by averaging the local deviations of the tire from the round shape.
Obviously the P.P. measurement is normally greater
than that of the 1st harmonic. Tire manufacturers normally supply two different tolerances for the two eccentricities. The radial and lateral runout measurements
are automatically carried out after the out of balance
measurement without having to go into particular procedures. Remember to position the sonar sensors in
front of the surface to be measured before pressing the
button.

The maximum limit of the first harmonic can be
set (MAX. TRUE RUNOUT LIMIT). When this limit is
exceeded, the wheel balancer displays a warning and
diagnostic frame indicating an eccentricity condition
that needs to be corrected.

Figure 32 - Set Dimension
Machine Calibration
For machine calibration, proceed as follows:
1. Mount an average size wheel with steel rim. Es.:
6" x 15" (± 1")
2. Preset the wheel dimensions with GREAT CARE.
3. Follow the on-screen instructions.
Note: You can change the calibration weight from 40
to 100 g (1.40 to 4.00 oz)
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 0.01 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.
• Out of balance 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 out of balance or damaged. Balance,
repair, or replace.
• Out of balance in brake rotor(s) or drum(s).
• Suspension out of alignment. Align the vehicle and
replace any damaged or worn parts.

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.
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
other manufacturers may not fit or function properly,

WARNING
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.
CAUTION
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.
Important: Always be sure to remove the wheel
assembly from the pneumatic shaft before disconnecting the air supply from the machine.

Glossary
ALUS -Alloy wheel mode that typically requires the
use of one or two adhesive weights for correction.
Balancer Flange – Disk that mates with the disk of
the wheel mounted to the balancer. The flange also
serves to keep the wheel perfectly perpendicular to its
axis of rotation.
Balancing Cycle – Sequence of operations performed
by the user and the machine, beginning from the start
of the wheel spin to the time that the wheel is braked to
a standstill after the out of balance signals are acquired
and the relative values calculated.
Centering – Procedure for positioning the wheel on
the spindle shaft with the aim of ensuring that the
rotational axis of the wheel is aligned with the center
of the shaft.
Centering Flange (accessory) – Device serving to
support and center the wheel. Also keeps the wheel
perfectly perpendicular to its axis of rotation. The centering flange is mounted to the balancer shaft by means
of its center hole.
Cone – Conical components with center hole. When
inserted on the spin shaft, serves to center wheels with
centre holes whose diameter is between maximum and
minimum values.
Dynamic Balancing – Operation in which out of bal-
ance is corrected by the application of two weights, one
on each side of the wheel.
Self-calibration – A procedure whereby suitable cor-
rection coefficients are calculated by starting from
known operating conditions. Self-calibration improves
the measurement precision of the machine by correcting, within limits, calculation errors that may arise due
to alteration of the machine’s characteristic over the
course of time.
Spin – Procedure starting from the action that causes
the wheel to rotate and the successive free rotation of
the wheel.
Hubnut – Device for clamping the wheel to the bal-
ancer. The hubnut features elements for engaging to the
threaded hub and lateral pins that are used to tighten it.
Static Balancing – In static balancing only the static
component of out of balance is corrected. This is
achieved by fitting a single weight, usually at the
center of the rim channel. The accuracy of this system
increases as the width of the wheel decreases.
Threaded Hub – Threaded part of the shaft that is
engaged with the hubnut to clamp the wheel. This
component is supplied disassembled from the machine.
Out of balance – Non-uniform distribution of the
wheel mass that results in the generation of centrifugal
force during rotation.
