IMPORTANT SAFETY 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.

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.

9. Keep guards and safety features in place and in
working order.

23. Use only manufacturer’s recommended attach­ments and accessories.

Owner’s Responsibility

To maintain machine and user safety, the responsibility

of the owner is to read and follow these instructions:

Definitions of Hazard Levels

Identify the hazard levels used in this manual with the

following definitions and signal words:

• 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

DANGER

Watch for this symbol:

DANGER

It Means: Immediate hazards, which will result in

severe personal injury or death.

WARNING

Watch for this symbol:

WARNING

It Means: Hazards or unsafe practices, which could

result in severe personal injury or death.

CAUTION

Watch for this symbol:

CAUTION

It Means: Hazards or unsafe practices, which may result

in minor personal injury or product or property damage.

• 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.

Watch for this symbol! It means BE ALERT! Your safety,

or the safety of others, is involved!

Important: Always read and follow the information box instructions. • iii

ÌBalancing Your First Tire

1. Turn the machine OFF then
ON (resets machine).

| Note: The machine wakes up using standard clip-

on wheel weight locations (Clip 1 & Clip 2) and
wheel dimensions.

2. Mount a tire/wheel on the bal­ancer that will use standard
clip-on wheel weights.

Use the most appropriate mounting method.

3. Always remove any weights
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.

Figure 1 - Clip-On Weight Location

8. Inboard center bar blinks.

Note: If an inboard corrective weight is not

required, the wheel will stop at the outboard cor­rective weight location, go to step 11.

9. Attach inboard corrective
weight.

Attach specified weight amount at top-dead-cen-

ter on inside flange of wheel.

10. Press NEXT; wheel rotates.

11. Outboard center bar blinks.

12. Attach outboard corrective
weight.

Attach specified weight amount at top-dead-cen-

ter on outside flange of wheel.

13. Lower the hood to respin the
tire/wheel and check balance.

The weight readings should now be 0.00.

Note: Throughout this manual tire dimensions are

referred to as A, W, and D, see figure 2.

Note the value entry of A & D dimension.

5. Enter Width wheel dimension.

For Manual Entry — Use plastic calipers to mea-

sure wheel width. Press W key. Use keypad to
enter Width value (between 2.0 and 20.0 inches).

For Automatic Measurement — Lower hood.

Note value entry of W dimension.

6. Lower the hood; wheel spins
and unbalances are measured
and displayed.

Figure 2 - A, W, and D Tire Dimensions

The corrective weight amount appears in the

weight display window for inboard and outboard
weight locations.

7. Raise hood after tire stops
rotating.

Note: Wait for wheel to stop before raising the

hood.

3D - Stop and Lock Feature

The balancer will stop the wheel on the inner plane
first if a weight is needed on the inner plane. If no
weight is needed on inner plane, the wheel will stop
at the outer plane first. If in fine balancing mode, the
wheel will stop at plane that calls for most weight.

2D - Stop Feature

At the completion of the balance cycle, the wheel
assembly will come to a complete stop; then the drive
will release the wheel. Then the operator can manually
index to the proper plane using the indexing guides on
the front panel.

Important: Always read and follow the information box instructions. • 3
