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.
Read entire manual
before assembling,
installing, operating,
or servicing this
equipment.

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.

Installation and Setup
A factory trained COATS®Service Technician must
perform the install, setup, and initial test procedures
on your 6401 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 will produce inaccurate balance readings.
Do not operate the balancer when it is still bolted
down or 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.
Unpacking
Check carton and pallet for crushed corners, broken
slats, gouges, and punctures which may indicate hidden damage. Make a note of all external damage on
the receiving waybill. Freight damage is the responsibility of the delivering carrier.
Initial testing and training are provided by our
COATS®distributor.
Remove outer carton from pallet. Remove strapping
holding hood in shipping position. Locate and remove
accessories. Notify manufacturers representative of
any missing accessories that were ordered.
Perform HOOD AND POD SET-UP.
Remove the single lag bolt and loosen the two (2)
anchor bolts holding the balancer to the pallet. Locate
and install the top two (2) accessory pegs. Carefully
slide the balancer off the pallet and move to final location.
Do not use the control pod, control pod
arm, faceplate, hood or stub shaft to lift the
balancer.
