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.

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.

Control Panel Quick Reference Screen Saver Mode (Video)
By default, the 1250 video version wheel balancer is shipped with the screen saver mode set to dim the dis­play back light after a period of inactivity (20 minutes).
Press and hold the SHIFT key and press 0; then 18 to cycle through the screen saver modes. For each mode, the balancer will display a short demo of the active back light option. The mode options are as fol­lows:
In most cases, to reactive the back light, just mount­ing a wheel, rotating the wheel or pressing a key will provide the input to wake the balancer back up.
Weight Display and Weight Position Windows
Two weight display windows, one inboard and one outboard, are positioned above the wheel cross sec­tion diagram. After a wheel measurement cycle, the balancer calculates the corrective weight amount and indicates it in the appropriate display window. All weight readings are shown in ounces or grams.
The “ Total Static” window indicates the value of the total static unbalance. See MATCH BALANCE (Optimization) on page 16 for further details.
Located on either side of the wheel cross section dia­gram are the weight position bars, one inboard and one outboard. After a measurement cycle, rotate wheel until the center weight position bar blinks, indi­cating the correct weight placement position is at top­dead-center.
Note: When in laser mode (T2-Tape Laser Locator), special blinking bars appear on either side of the cen­ter bar to indicate the correct outboard weight place­ment position. Also remember that the laser beam dot will stop blinking when it is at the correct weight place­ment location.
Mode Indicators
The mode indicator will show whether the mode is
activated. Modes are as follows:
Operator A or Operator B - when illuminated, indi-
cates which operator memory is selected.
Match Balance - when illuminated, indicates that the
Match Balance (Optimization) mode is activated.

Balancing Using Direct Select™
A variety of wheel configurations can be balanced using this wheel balancer. Read through this section, it will help in determining which mode and options are best suited for certain wheel assemblies. Refer to pages 1 - 7 to balance the wheel, for measurement and weight placement techniques. Refer to pages 8 ­11 for Control Panel functions.
Remember: As with any balancing procedure, first remove any weights attached to the wheel, inspect the tire and wheel, and use the most appropriate bal­ancer mounting method before beginning.
Dynamic Balancing
Choose a dynamic balance to balance a wheel using two planes for correction. Direct Select™ the weight option that best fits the available weight locations.
Clip-on Weights -The default; used for most passen­ger and light truck tire assemblies using the most com­mon location for corrective weights. Clip-on weights are placed on the inner and outer rim flanges.
Have the following items handy: appropriate style clip-on weights.
Direct Select Weight position Clip 1 and Clip 2 (weight locations illuminate). At these locations place the corrective weight amount at top-dead-center.
Tape-A-Weights
®
and Hidden Tape-A-Weights®-
Used when one or both clip-on weight locations are not possible or desired. Select the weight location(s) that best fits the rim configuration.
Have the following items handy: appropriate style clip-on weights and Tape-A-Weights
®
.
Direct Select Weight position Clip 1 or T1 - Tape and T2 - Tape, T3 - Tape or Clip 2 (weight locations illumi­nate). At all locations, except T-2 Tape, place the cor­rective weight amount at top-dead-center. If the T2 ­Tape weight location is selected, the balancer acti­vates its Laser Guided Operation™ feature (see page 6).
Static Balancing
Choose a static balance for wheel assemblies that are not possible to balance dynamically or for narrow wheels. For example, a motorcycle wheel that has a small wheel width.
Have the following items handy: an appropriate wheel assembly mounted on the balancer and a selec­tion of weights.
When in static mode, the active Direct Select Weight location is Clip 1 or T2 - Tape. Select the weight location(s) that best fits the rim configuration.
At the Clip 1 location, place the corrective weight amount at top-dead-center. If the T2 - Tape weight loca­tion is selected, the balancer activates its Laser Guided Operation™ feature (see page 6).
Note: If using a patch weight, refer to Patch Weight Balance, page 13.
Special Balancing Modes
A special balancing mode is required for the following methods.
EB (if available, model number supports EB) - An alternate approach to balancing a tire and wheel assembly. The technology seeks first to eliminate the static imbalance in a wheel assembly then, based on several parameters, calculates the minimum amount of corrective weight needed to bring dynamic imbal­ance within acceptable limits.
Balancing wheel assemblies using EB often results in the application of less corrective weight. In addition to the potential direct savings in wheel weights, there is a potential productivity savings due to a reduction in the number of “ re-spins” necessary to achieve an acceptable balance condition.
To enable the EB function, press and hold the SHIFT key and press 0, then press 71 to toggle the EB mode ON or OFF (software version 2.0.1.6 and forward). The default is OFF.
For additional information, see Direct Select™ Weight Placement Location on page 11.
Behind Spoke (T2 - Tape Mode Only) - Used to bal­ance with two adhesive weights located behind the spokes in the outer correction plane.
Only use the Direct Select Weight position
Clip 1 or T1 - Tape and T2 - Tape (weight loca-
tions illuminate). When the T2 - Tape weight location is selected, the balancer activates its Laser Guided Operation™ feature (see page 6).
Begin by following the Laser Guided Operation™ pro-
cedure, steps 1 through 4 on page 6.
1. When unbalance is displayed, rotate wheel until
inboard center bar blinks. Attach inboard corrective weight at top-dead-center.
2. Next, rotate wheel until the outboard center bar
blinks and the two bars on either side blink.
Note: The laser locator dot will stop blinking.
3. Select the BEHIND SPOKE mode option.
Important: Be sure that the Spoke 1 and Spoke 2
locations are on either side of the original outboard cor­rective weight location, as shown in figure 15.
4. Rotate the wheel toward front so the laser locator
dot is behind the first spoke; press SPOKE 1 (indicator illuminates).
5. Rotate the wheel toward rear so the laser locator
dot is behind the second spoke; press SPOKE 2 (indi­cator illuminates). Now at the spoke 2 location, the outboard center bar stops blinking and the two bars on either side blink.
Note: The laser locator dot will stop blinking.
Figure 15 - Spoke 1 And Spoke 2 Locations On Either Side
Of Original Outboard Weight Location
6. Center and attach the spoke 2 outboard corrective
weight at the laser locator dot location (see figure 11 page 6).
7. Next, rotate the wheel toward the spoke 1 loca-
tion until the outboard center bar stops blinking and the two bars on either side blink.
Note: The laser locator dot will stop blinking.
8. Center and attach the spoke 1 outboard corrective
weight at the laser locator dot location (see figure 11 page 6).
9. Respin tire/wheel to check balance.
Patch Weight Balance - Use a static patch weight bal-
ance when there is a very large unbalance in a tire assembly or if a very large tire has a large unbalance. A weighted balance pad (patch weight) is placed inside the tire in the center to compensate for the large unbal­ance.
Direct Select Weight position Patch
Static (weight location illuminates). At this location place the corrective weight amount at top-dead-center.
Have the following items handy: measuring tape and
various patch weight sizes.
Note: Before proceeding with Patch Weight Balance,
it is recommended that you use the Match Balance (Optimization) procedure first, see page 16, in order to use the smallest patch weight.
The Patch Weight Balance involves the loos­ening of tire beads and the inflation of a tire. Training is necessary in tire changer operation and understanding the dangers involved during bead seating and tire infla­tion before attempting this stage of the Patch Weight Balance procedure. Read the operators manual supplied with the tire changer and consult a supervisor.
The patch weight balance steps are as follows:
1. Direct Select Weight position PATCH STATIC. The
balancer automatically sets itself for a STATIC balance.
2. Measure the outside tire
diameter, see figure 16, and enter this diameter manually using the keypad.
Figure 16 - Measure Outside Tire Diameter
3. Spin the wheel.
4. Rotate the wheel until the center weight position
bar blinks. Next, mark the tire and rim at 12 o’ clock. Then remove the wheel assembly from the machine.
5. Disassemble the tire and rim. Place patch weight
in the tire at location marked on the tire. Reassemble tire and rim matching the marks on the tire and rim.
6. Complete by balancing the wheel assembly fol-
lowing normal procedures.

Mounting Wheel on Spindle
Shaft
Avoid back injury, seek assistance when lift­ing heavy tire/rim assemblies onto the bal­ancer shaft.
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.
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.
1. Place the cone spring onto the shaft with the large
end towards the faceplate.
2. Select the cone that best fits the center hole in the
wheel. Slide the cone onto the shaft with the large end towards the cone spring.
3. Lift the wheel onto the shaft and center it on the
cone.
4. Attach the pressure cup to the hub nut and install
the assembly onto the shaft. Tighten securely.

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.
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.
Figure 18 - Front Cone Mounting
Alternate Mounting
If the wheel has a protruding outer hub which will not permit the use of the pressure cup, or the cup will not permit the hub nut to engage at least four turns of the shaft, this alternate method should be used.
1. Place the cone spring onto the shaft with the large
end towards the faceplate.
2. Select the cone that best fits the center hole in the
wheel. Slide the cone onto the shaft with the large end towards the cone spring.
3. Lift the wheel onto the shaft and center it on the
cone.
4. Use the small nylon spacer (no-mar ring) or a cen-
tering cone to press against the outer wheel hub.
5. Install the hub nut (without the pressure cup) onto
the shaft. Tighten securely.

Match Balance (Optimization)
The Match Balance (Tire/Rim Weight Optimization) procedure is used to determine the best mating of tire and rim that will result in the least amount of total unbalance of the assembly. It requires two spins and two rotations of the tire on the rim. Match Balance may be needed when:
• The customer complains of ride problems.
• The balancer calls for Total Static weights in excess of 3 ounces (85 grams) on passenger car tires.
Note: A high unbalance may indicate the improper
mounting of the assembly on the balancer, or a rim that is out of round or misformed, or a tire with a bub­ble or other problem. If the unbalance is excessive, it may be prudent to replace the rim, the tire, or both. If either is replaced, do not continue with Match Balance. Balance the new tire and rim and evaluate the readings.
Match Balance Mode
If you choose to use Match Balance to correct for a
condition, such as a large static unbalance, then follow
the information box instructions for the MATCH BALANCE procedure as outlined in the following steps.
Note: Use this procedure only after the wheel has
spun and the corrective weight amount is displayed.
Note: Use the total static display option. See BAL-
ANCE OPTIONS, page 11, for further details.
1. Press and hold the SHIFT key and press 5 to select
the Match Balance mode. A “ 1” will appear in the outboard weight display.
2. Raise the hood and rotate the wheel until the valve
stem is at top-dead-center. Mark the tire sidewall at the valve stem.
3. Press 1 on the control panel; a “ 2” will appear in
the outboard weight display.
4. Remove the wheel assembly from the balancer.
The Match Balance involves the loosening of tire beads and the inflation of a tire. Training is necessary in tire changer opera­tion and understanding the dangers involved during bead seating and tire infla­tion before attempting this stage of the Match Balance procedure. Read the opera­tors manual supplied with the tire changer and consult a supervisor.
5. Using a tire changer, rotate the tire 180 degrees
on the rim.
6. Remount wheel assembly on the balancer. Press 2
on the control panel; a “ 3” will appear in the outboard weight display.
7. Lower the hood and press START. The wheel
spins.
8. When the wheel stops spinning, raise the hood
and rotate the wheel until the valve stem is at top­dead-center.
9. Press 4 on the control panel.
Weight amounts appear on the control panel. The amount in the inboard weight display is the weight imbalance for the rim. The amount in the outboard weight display is the weight imbalance for the tire. Use these weight amounts to determine the suitability of the rim or tire.
Note: If either the rim or the tire weight amount is close to zero or zero then using Match Balance will not affect the total unbalance of the assembly.
10. Rotate the wheel until the outboard weight posi-
tion bar flashes. Mark the tire at top-dead-center.
11. Remove wheel assembly from balancer.

Calibration
Machine Calibration
Important: Be sure to use the correct calibration
weight amount: a 4-ounce calibration weight in ounce mode or a 100-gram calibration weight in gram mode
Important: Starting with software revision 2.0.1.9,
the factory default is set for a 4-ounce calibration weight amount for both the ounce and the gram weight measurement modes. Therefore, for Machine Calibration, only the 4-ounce calibration weight is nec­essary regardless of the weight measurement mode setting.
To use a 100-gram calibration weight amount, when first prompted to use the 4-ounce weight in calibration mode, press the gram/oz key (SHIFT 9) to toggle from
4.00 to 100. Once set, the balancer retains this new default preference in memory.
Important: Starting with software revision 2.0.1.6, the user is only required to enter the D dimension. Note that prior software versions still require that the user enter all the DIMS (A, W, and D wheel dimen­sions).
1. Mount a 16-inch steel tire/wheel assembly on the
balancer. A balanced tire/wheel is required.
Note: Position wheel so that no weights are on either flange at the top-dead-center location. Turn the machine OFF then ON.
2. Press and hold the SHIFT key and press 1 to select
the CAL MACHINE mode.
3. Enter the D dimension.
4. Lower the hood and press START.
5. After spin, raise the hood. Rotate wheel until the
outboard center bar blinks; attach calibration weight to the outside flange at top-dead-center.
Figure 20 - Calibration Weight On Outside Flange At Top­Dead-Center
6. Lower the hood and press START.
Important: It is critical that the inner weight be
placed accurately to achieve proper calibration. If the calibration weight is not moved from the outside flange directly across to the inside flange, an inner weight placement error will occur. To correct, follow the information box instructions.
7. After spin, raise the hood. Rotate wheel until the
inboard center bar blinks; move and attach the calibra­tion weight to the inside flange at top-dead-center.
Figure 21 - Calibration Weight Moved (Directly Across) To
Inside Flange
8. Lower the hood and press START.
9. Calibration complete. Press NEXT.
Arm Calibration
Important: Always perform the Arm Calibration
immediately after Machine Calibration. The balancer software will not permit it otherwise.
During Machine Calibration, the balancer software calculates both the A and W dimensions. The Arm Calibration gives the balancer software a reference point to the edge of the faceplate and home position. When the user enters the A dimension from the arm rod, it calculates the difference from the machine cali­bration A and uses that as a factor for the manual A entry. Arm calibration also gives the D dimension a ref­erence point from home position.
Note: Starting with software revision 3.0.0.0, CdE will not appear in the INBOARD weight display and the user is no longer required to enter the Code 96. Note that prior software versions still require that the user enter the Code 96 at the CdE prompt to access the Arm Calibration mode.
1. Complete the Machine Calibration procedure (see
page 17).
2. Press and hold the SHIFT key and press 3 to select
the CAL ARM mode.
18 • Important: Always read and follow the information box instructions.
3. Bring the tip edge of the arm precisely to the outer
edge of the faceplate and hold it there while pressing the NEXT key. (If necessary to reach the faceplate accurately, loosen the calibration wheel temporarily.)
4. With the arm still at the edge of the faceplate,
enter the A dimension shown on the arm rod. Press the NEXT key.
Figure 22 - While Holding Arm at Faceplate Edge, Enter A
5. Move the arm to its home position and press the
NEXT key.
6. Move the arm to the clip-on weight location on the
rim flange and hold it there while manually entering the D dimension. Press the NEXT key.
7. While still holding the arm at the clip-on weight
position on the wheel, enter the dimension read off the arm rod. Press the NEXT key.
8. Return the arm to home position; calibration is
complete.
Important: To redo the Arm Calibration procedure,
press and hold SHIFT and press 0, then press 19 to bypass the Machine Calibration requirement. Always use the same wheel assembly that was used during the machine calibration or else the calibration will not be correct.
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 and under the balancer
clear. Remove any tools or other items that are leaning against the balancer. 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.
6. To replace Arm Laser battery, remove cover (fig.

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 0.05 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 appropriate adapter to mount the wheel to the bal­ancer. Balance the wheel with the wheel cover or trim ring attached to the wheel.
• Incorrectly mounted tire and wheel. Remount cor­rectly.
• Damaged wheel bolt holes. Replace wheel.
• Worn universal joints. Replace as required.
• Drive shaft unbalance or damaged. Balance, repair, or replace.
• Unbalance in brake rotor(s) or drum(s).
• Suspension out of alignment. Align the vehicle and replace any damaged or worn parts.
