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.
22. Use equipment only as described in this manual.
23. Use only manufacturer’ s recommended attachments and accessories.
Important: Always read and follow the information box instructions. • iii
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.

already attached to the wheel.
4. Enter A & D wheel dimensions
using offset arm.
For Automatic Measurement — pull offset arm
out to the wheel, hold it still at clip-on weight
position against wheel flange, and wait for BEEP.
Return arm to home position.
Clip-on Weight Location — viewed on a cut-away
rim for clarification.
