“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. Be sure that wheels are mounted properly, the hub
nut engages the arbor for not less than four (4)
turns, and the hub nut is firmly tightened before
spinning the wheel.
3. Read and understand this manual before operating. Abuse and misuse will shorten the functional
life.
4. Be sure the balancer is properly connected to the
power supply and electrically grounded.

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.

Operating the Balancer
Wheel Mounting
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.
Failure to tighten the hub nut properly may
result in the wheel dismounting, causing
personal injury and property damage.
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.
Back Cone Mounting
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 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.
Note: Use a nylon spacer (no mar ring) to protect custom wheel finishes.
4. Thread the hub nut onto the shaft, and tighten it
against the wheel. The wheel must be forced firmly
against the faceplate. The hub nut must engage the
threads for at least three full turns.
Note: If the hub nut will not tighten completely, use
the front cone mounting method.
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.
Front Cone Mounting
1. Select the cone that best fits the center hole in the
wheel.
2. Lift the wheel onto the shaft and slide it back
against the shaft faceplate.
3. Slide the cone onto the shaft and into the center
of the wheel. You will need to lift the tire to seat the
cone in the center hole.
4. Install the hub nut (without pressure cup) onto the
shaft. Tighten it securely against the cone. The hub nut
must engage the threads for at least three full turns.
Note: If the hub nut will not tighten completely
because of a lack of threads, use an additional cone as
a spacer between the mounting cone and the hub nut.
The wheel must be forced firmly against the faceplate.

Self-Calibration
For machine self-calibration proceed as follows:
- Fit a wheel with steel rim of average dimensions on
the shaft. Example 6" x 14" (± 1")
- Preset the exact dimensions of the wheel mounted.
IMPORTANT !! Presetting of incorrect dimensions
would mean that the machine is not correctly calibrated, therefore all subsequent measurements will be
incorrect until a new self-calibration is performed with
the correct dimensions!!
- Perform a spin under normal conditions.
- Add a 4.00 oz (ounce mode) or 100 gr. (gram mode)
calibration weight on outside in any angular position.
- Shift the caibration weight straight across to the
inside; keeping the same angular position.

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 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.
5. Use only COATS®accessories. Accessories from
other manufacturers may not fit or function properly,
and may damage the balancer.
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 0.10 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

Installation Instructions
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.
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.

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
Space Requirements
Unpacking the Unit
1. Remove the shipping carton from the pallet.
2. Remove all loose parts and accessories packed
around the unit.
Remove Balancer from Pallet
3. Remove the shipping bolts that hold the balancer
to the pallet.
Do not use the control panel, control panel
base, accessory storage, faceplate, hood or
shaft to lift the balancer.
Use help to remove the balancer from the
pallet. The unit is heavy and the weight is
not evenly distributed. Dropping the unit
may cause personal injury or equipment
damage.
4. Lift the balancer off the pallet and place it in its
operating location.
5. Install and tighten the threaded stud into the end
of the motor shaft.
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.
Initial Testing
1. Plug the unit into an appropriate power outlet. If
the circuit breaker for the outlet is off, turn it on.
2. Turn the balancer on. The power switch is on the
back of the unit.

Hood Installation
1. Install plastic bushing on end of hood tube.
2. Insert hood tube through hole and slide through
hood mounting bracket. The bushing will only fit one
way due to its molding.
3. Install second plastic bushing on the end of the
hood tube protruding from the bracket.
4. Slide on the stop ring. The set screws may need to
be loosened to install slide ring. Adjust the stop ring so
the notch is parallel to the floor when the hood is in the
down position.
5. Install the plug in the end of the hood tube.
6. Tighten the set screws to secure stop ring in
place.
7. Raise the hood.
8. Install hood spring. This attaches to the cam studs
on the hood bar and mounting bracket.
9. Lower the hood.
10. Screw on hood switch with two screws. The
height of the switch will need to be adjusted to ensure
the switch button is up when the hood is down. The
switch button should fit neatly in the cutout of the stop
ring.
11. Connect the switch wiring end to the three-
prong connector on the back panel of the chassis.
12. Test the hood switch with the auto spin feature
to ensure proper installation. If problems check the
height of the hood switch button for proper operation.
