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).
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:
• 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.

Power Switch
The ON/OFF decal, see figure 4, indicates the location of the ON/OFF switch at the back of the balancer.
The circuit breaker reset button is also at this location.
Air Gauge Panel (If equipped)
NEVER exceed tire manufacturer’s recommended air pressure. Tires can explode,
especially if inflated beyond these limits.
Keep hands, arms, and entire body back
from inflating tire. Avoid distraction during
inflation. Check tire pressure frequently to
avoid over inflation. Excessive pressure can
cause tires to explode, causing serious
injury or death to operator or bystander.
Do not lower the hood with the clip-on air
chuck attached to the tire’s valve stem. With
the hood start feature ON, the tire will start
rotation causing damage to the wheel and
balancer and possible personal injury.
As shown, the wheel balancer is equipped with the
capability to adjust the air pressure of the tire. The
INFLATE push button supplies air through the hose
and clip-on air chuck located at the wheel guard. When
the chuck is attached to the valve stem, air pressure is
indicated on the gauge. Excess pressure can be
reduced using the MANUAL TIRE BLEED VALVE. See
figure 4.

ALU modes - Select the MODE option for the
modes menu. All the ALU modes are dynamic balance.
Choose the option that best fits the available weight
locations.
- ALU-1
- ALU-2
- ALU-3
- ALU-4
Have the following items handy: an appropriate
wheel assembly mounted on the balancer and Tape-AWeights™. You must use the appropriate measurement and weight placement technique for each plane
selection (page 7) to balance the wheel.
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.
Select the MODE option for the modes menu
and then select the STATIC MODES option .
Choose the option that best fits the available weight
locations.

Patch Weight Balance - Use a static patch weight balance 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.
- PATCH TYPE WEIGHTS (static)
- DIAMETER ↑
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 Optimization
(Match Balance) procedure first, see page 18, 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. Measure the out-
side tire diameter, see
figure 26, and enter this
diameter manually on
the patch menu screen,
DIAMETER option .
Figure 26 - Measure Outside Tire Diameter
2. Select PATCH option . The balancer automati-
cally sets itself for a STATIC balance.
Figure 27 - Patch Screen
3. Move the offset arm tip to the inside of rim to set
tape-a-weight™ location. Wait for beep.
4. Spin the wheel.
5. Align the on-screen arrows. Next, mark the tire 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

Additional Options
Be aware of the following options that appear on
selected screens. Press the numbered key that corresponds with the key icon for each additional option
described below.
OZ/g - toggle between ounce or gram weight
measurements. Note that this option appears on
the weight placement screen (profile view) after
the wheel has been spun.
Spoke -To balance with adhesive weights located
behind the spokes in the outer correction plane.
The spoke balance steps are as follows:
1. Begin by balancing the wheel assembly following
normal procedures for either the ALU-1 or ALU-2
mode.
2. When the unbalance is displayed, attach the left
side corrective weight.
3. Next, select SPOKE option .
4. Rotate the wheel to position the right side yellow
marker (ball) until it turns green. Select NEXT option
.
5. Rotate tire toward you until the first spoke is at 12
o’clock or TDC. Hold location and press .
6. Rotate tire away from you (past unbalance point)
until the next spoke is at 12 o’clock or TDC. Hold location and press .
7. Observe, by rotating the tire, that there are now
two hidden weight locations located behind the two
specified spokes (3D mode), See figure 28. Use the
offset arm to attach the two right side corrective
weights.
Figure 28 - Spoke Weight Placement Screen
Unspoke - If you decide not to use the spoke
option, press this option. Only one right side
marker (ball) will display.
L.T. - For one spin only, press this to change the
weight roundoff from 0.25 oz. to 0.5 oz. and
reduced measured width 1/2-inch Note that this
Light Truck option shows up after taking a dimension reading with the offset arm.
Figure 29 - The L.T. Icon Indicates Weight Roundoff Change
Econo Balance Mode (if available, model number supports EB) -
Toggle the Econo Balance Mode
ON or OFF.
Set to OFF.
EB (Econo Balance) 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 minimum amount of corrective weight
needed to bring dynamic imbalance within acceptable
limits.
Balancing wheel assemblies using EB mode often
results in the application of less corrective weight. In
addition to the potential productivity savings due to a
reduction in the number of “re-spins” necessary to
achieve an acceptable balance condition.

Matching
A matching procedure may involve 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 a
matching procedure. Read the operators
manual supplied with the tire changer and
consult a supervisor.
Typically, if the static limit unbalance is exceeded, the
operator will choose Optimization (Match Balance) to
correct the situation.
To view the Static-on-Screen™ value, press the
key, select the SPECIAL FUNCTIONS option , and
set the STATIC UNBALANCE DISPLAYED option
to ON. The Static-on-Screen™ reading, see page 9, will
appear in the upper left-hand side of the screen.
Optimization (Match Balance)
The 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. Optimization 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 optimization. Balance
the new tire and rim and evaluate the readings.
If you choose to use Optimization to correct for a con-
dition, such as a large static unbalance, then select the
key for the menu screen, and then select the
OPTIMIZATION (MATCH BALANCE) option .
Follow the on-screen instructions for the TIRE/RIM
WEIGHT OPTIMIZATION procedure as outlined in
the following steps.
Figure 30 - Tire/Rim Weight Optimization Screen
Note: Use this procedure only after the wheel has
spun and weights are displayed.
1. Rotate arrow on faceplate to 12 o’clock. Place a
mark (backside of the wheel) on the rim at 12 o’clock.
Press the NEXT option .
2. Remove the wheel assembly from the balancer.
3. Using a tire changer, rotate the tire 180 degrees
on the rim.
4. Replace wheel assembly on balancer and align the
faceplate arrow with the mark on rim. Lower the hood
and press the NEXT option . The wheel spins.
5. Rotate the wheel until a red box appears at the
yellow arrows. Put a second mark (frontside of wheel)
on the rim at 12 o’clock.
6. Rotate the wheel until a red box appears at the
green arrows. Put a third mark (frontside of wheel) on
the tire at 12 o’clock. Press the NEXT option .
Note: The rim unbalance and tire unbalance values
are displayed on the screen.
7. Remove wheel assembly from balancer.
8. Using a tire changer, align the mark on the rim
with mark on the tire.
9. Replace the wheel assembly on the balancer.
Align the faceplate arrow with the previous mark (backside) on the rim to check improvement or just continue
with step 10.
10. Press NEXT option and balance the assembly

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. Select the cone that best fits the center hole in
the wheel. Slide the cone onto the shaft with the large
end towards the faceplate.
2. Lift the wheel onto the shaft and center it on the
cone.
3. 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 34 - 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. Select the cone that best fits the center hole in
the wheel. Slide the cone onto the shaft with the large
end towards the faceplate.
2. Lift the wheel onto the shaft and center it on the
cone.
3. Use the small nylon spacer (no-mar ring) or a cen-
tering cone to press against the outer wheel hub.
4. Install the hub nut (without the pressure cup) onto
the shaft. Tighten securely.

sensor (option): the number decreases when a surface
is brought closer to the sensor device.
E (Vco I) - Piezo Output.
F (Diam) - Check for correct operation of the diame-
ter gauge; the number increases when the offset arm
is rotated outward.

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 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.

Maintenance
Instructions
The balancer requires only minor maintenance to
keep the unit operating properly.
1. Keep the display clean and clear. Use a vaporizing
cleaner only. 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 the weight tray, accessory posts, pegs, and
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.
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.
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.
4. Clean the sensor unit(s) using only a soft, water-
dampened cloth (not wet). Do not use solvents as they
may damage the white sensor area.
5. Keep the area around the balancer clear. Remove
any tools or other items that are leaning against the
balancer. Keep the area under the balancer clear.
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.
6. Use only COATS®accessories. Accessories from
other manufacturers may not fit or function properly,
and may damage the balancer.

Installation 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.
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.
Electrical Requirements
The wheel balancer requires a 115 VAC, 60HZ, singlephase power. Plugs into standard 15 amp outlet.
Always have a qualified electrician install 3-prong
receptacles in accordance with state and local codes.
Some special order wheel balancers may require different voltages. See serial tag for the appropriate
power requirements of your machine.
Setup
Do not use the monitor, monitor base,
accessory storage, faceplate, hood or shaft
to lift the balancer.
Do not attempt to install and setup the unit
yourself. Contact COATS
®
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.
Air Supply Connection
The wheel balancer requires a minimum 2 CFM air
source at 60 PSI. This system is only intended for
adjusting the inflation of tires.
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.

Glossary of Terms
BDC - an acronym for bottom-dead-center, also
referred to as the 6 o’clock position.
Dynamic Balance - balancing a wheel using two
planes for correction. Dynamic balance means the
wheel is in balance when in motion about its rotational
axis. Also, a wheel is statically balanced when dynamically balanced. However, a wheel that is statically balanced is not necessarily dynamically balanced.
Hub Centric - refers to mounting and means the
wheel is centered to the vehicle by the center hole on
the wheel and the pilot on the vehicle axle. The maximum clearance between the wheel’s center hole or
bore and the axle pilot is between 0.0015 and 0.006
normally.
Inner Plane - the closest corrective weight location
from the balancer.
Lug Centric - refers to mounting and means the
wheel is centered by the studs and nuts mounted on
the axle of the vehicle. This is the least desirable way
to mount a wheel; very difficult to maintain the wheel
centering on the vehicle axle.
Offset Arm - pivoting arm that measures A & D
wheel dimensions.
A - distance measured from the balancer
(“0” on the offset arm) to the inner plane of
the rim (inner weight location).
D - diameter of the wheel at the weight
location, which is not always the same as
the bead seat diameter that determines tire
diameter.
W - width between the inner and outer
planes.
Outer Plane - farthest corrective weight location
from the balancer.
Static Balance - balancing a wheel with only a single
corrective weight or splitting two weights at the same
radial location.
TDC - an acronym for top-dead-center, also referred
to as the 12 o’clock position.
Weight Planes - the location for corrective weights.
