Safety
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.
Failure to follow danger, warning, and caution instructions may lead to serious personal injury or death to operator or
bystander or damage to property. Do not
operate this machine until you read and
understand all the dangers, warnings and
cautions in this manual. For additional
copies of either, or further information,

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 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 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 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 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 attachments.

Before You Begin
Receiving
The shipment should be thoroughly inspected as
soon as it is received. The signed bill of lading is
acknowledgement, by 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 balancer requires a 220 VAC, 60Hz, three-phase
power supply with 20 amp fuse or circuit breaker, or a
220 VAC, 60 Hz, single-phase power supply with 20
amp fuse or circuit breaker.
The three-phase balancer is equipped with an
approved cord and a 4-prong grounding plug to fit a
Hubbell 2420 or Bryant 71520 grounding receptacle
(not included).
The single-phase balancer is equipped with an
approved cord and a 3-prong grounding plug to fit a
Hubbell 2320 or Bryant grounding receptacle (not
included).
The receptacles should be installed by a qualified
electrician in accordance with state and local codes.

Installation and Setup
A factory trained COATS®Service Technician must perform the
install, setup, and initial test procedures on your 950, 1025,
1050, or 1055 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 3
feet. If the balancer is not level, does not sit solidly on its 3 feet,
or is placed on an unstable floor, the balancer will not function
properly and will produce inaccurate balance readings.
The balancer is not designed to be bolted down, nor will it
function properly if left on the pallet.
Select a location for the balancer that provides a level, solid
floor, and adequate clearance around and above the balancer
(Figure 1). 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.
Unpack and Setup the Unit
1. Remove the carton from the pallet.
2. Remove the shipping bolts in the three support feet.
3. Cut the strap holding the hood in shipping position.
Do not use the control pod, control pod arm, faceplate, hood or stub 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.
