Operation of the BalancerNOTE: Read all instructions before proceedingwith operation of the balancer.WARNING: For operator safety pleaseread and follow the precautions outlinedon page 3 of this manual.All balancer functions are input into the main computerthrough the large easy to read touch panel. Althougheach wheel tire assembly differ in some ways all balancingjobs require basically the same procedure. Theorder of events to take place are:1. Inspection of the wheel/tire assembly2. Mounting wheel onto shaft or adapter3. Entry of wheel parameters4. Selection of Balancing Mode or placement5. Spinning the wheel6. Applying the recommended weight7. Check spin if desired8. Dismounting the wheelThe following operation instructions will follow the basicoutline above.Step 1: Check ListObserve Before Balancing Wheel1. Check for proper air pressure. If not correct, inflateto correct pressure.2. Check for any foreign material inside tire. If present,remove before balancing tire.WATER IS FOREIGN MATERIAL!3. Be sure tire and wheel are free of excessive dirt, rustand large stones. Use wire brush on back side of wheelif necessary.4. Remove old weights — old weights may be impropervalue or in wrong location.5. Be sure that the right size tire has been mounted onthe wheel.Step 2: Wheel MountingStandard Wheels (back cone mount)Nearly all standard wheels and many alloy wheels haveaccurately machined center holes, and they should bemounted with center cones. Accurate balancing dependson accurate mounting of the wheel and correctseating of the cone in the pilot hole to insure that thewheel is centered on the shaft.Mount the wheel as detailed below in Figure 1:1. Mount proper cone against spring plate.2. Mount wheel on shaft in the same manner as youwould on the car.3. Mount pressure ring on speed nut and place againstoutside of wheel.4. Tighten speed nut securely with both hands.NOTE: Some wheels not hub centric may require theuse of an optional lug adapter plate.* An adapter plateallows a wheel to be mounted using the lug holes as acenter reference.* Cone, retainer cup, and wing nut may not be neededif adapter plate is used to mount wheel to balancershaft. See page 14 for lug adapter detail.Proper Size ConeBackingCollarCaptiveCoil SpringShaftPressure CupSpeed NutFigure 1 - Standard back cone mountingWarningFailure to tighten wing nut securely mayresult in serious personal injury.Page 9

Press wheel width button .and enter the measured diameter directly usingthe numeric keypad or use the Quick Set methodby rotating the wheel assembly until the desirednumber appears in the width parameter window.Figure 46.0Page 11

Step 4: Spinning the WheelPress "ENTER" or lower the hood to spin. The machinewill spin the wheel assembly for several seconds.NOTE: The 7 Series Balancers feature selectable automaticspin. The shaft spins when the hood guard islowered or ENTER is pressed. Auto-spin can be disabledby pressing the keys "F6" and ENTER. Eachtime F6 is entered the autospin feature toggles on/off.Warning!! Do not attempt to bypass or disablethe built in hood guard safety features.These guards are for your safety.The computer calculates for imbalance and locationusing the current parameters and mode.The balancer will go into a brake cycle to stop the shaftfrom turning. When the shaft has come to a stop, thedisplay will read the required weight amount and positionto place them.After spinning, to recalculate the readings for a differentplacement, balancing mode, or displayed units, simplypress the desired button. See Figure 5.Note: If at any time the wheel/tire assembly measuresover a total of three (3) ounces imbalance on eitherplane, a "Match Balance" is recommended. See page16 for details.Step 5: Placing WeightView the weight amount and location windows. SeeFigure 6. Weight values are displayed for the chosenmode location. Lift the hood guard. Rotate the wheelassembly until the position indicator LED turns green.Select the correct type weight and place at the indicatedposition. Continue to rotate the wheel assemblyto the next indicated placement position. Lower thehood guard for a check spin if desired.Figure 5 -- To recalculate the weight amounts and locationsusing a different balancing mode or change toounces/grams, press the appropriate button. The balancerwill display the proper weight amount for thatposition or mode without respinning.Weight PositionWeight Amount1.25 .75Figure 6 -- LED Display indicates weight amountand position.WARNING!: Be sure to use the proper typeclip weights - using the wrong type clipweight may cause serious personal injuryor damage to property.Step 6: Dismounting the WheelWhen the balance is complete, remove the wheel assemblyfrom the balancer. Mount onto vehicle usingthe manufacturers suggested torque specifications.Use manufacturers suggested lug torque whenremounting wheel onto hub.Page 12

WHEEL MOUNTING -- Specialty WheelsMost special wheels can be accurately mounted andbalanced using a centering cone. When using centeringcones, be certain cone is properly seated in thewheel's pilot hole.To balance a wheel with a deep neck, the front conemounting method may be necessary. Mount the wheelas shown below in Figure 7:Mount the wheel as shown in Figure 14 and balance asa “Standard” wheel.1. Mount offset spacer against the balancer backingplate.2. Mount wheel onto balancer shaft.3. Select proper cone and mount onto shaft and intowheel center hole as shown in Figure 8.4 Tighten wing nut securely.1. Mount wheel onto the balancer shaft.2. Place the proper cone inside the protruding neck ofthe wheel.3. Remove the clamping cup from the wing nut. Placethe small spacer ring on the nut if needed. Tightenwing nut securely.Offset SpacerLarge Truck ConeWing NutProper Size ConeWing NutShaftBuddTypeWheelFigure 8 -- Mounting offset wheelsDeep Neck WheelFigure 7 -- Front coning for deep-neck wheelsWARNING!! Failure to tighten wingnut securely may result in serious personalinjury.Truck WheelsOffset and Ford/Dodge Pinned Dual Wheels UsingOptional Offset SpacerSome light truck wheels are “standard”, except thatthey have offset centers which may extend around thebacking plate. Under normal conditions no spacer isrequired because of the unique design of the balancingshaft and bearing housing. For unusual applications,an optional offset spacer may be used. See the “OptionalAccessories for Computer Wheel Balancers”catalog for the part number.Pinned WheelsFord E/F 350 Series and Dodge 350 Series 1-Tontrucks (also some Specialty vehicles, such as motorhomes, ambulances, emergency rescue, tow trucks,etc.) may have the safety pinned dual wheels installedon the rear axles.The Offset Spacer was designed to provide clearancefor the pin on these wheels, with a tapered inner lip toallow the clearance needed for the outside mountedcone to fit inside of it without binding. Mount thesewheels as in Figure 8.Patch BalanceSome larger light truck tires may require an excessiveamount of weight to balance. For this reason a patchbalance may be recommended. Patch balancing issimply affixing a stick-on weight designed for the purposeinside the tire body. Wheel/tire weight should beoptimized first using a Match Balance procedure. Secondperform the actual patch balance procedure. Finally,perform a standard two plane balance. Byperforming the above procedure the amount of exteriorweight placed will be minimum and maximize the tireperformance.Page 13

Balancing Alloy WheelsCustom aluminum and alloy wheels mounted on today's highperformance autos require a service technician to take severalprecautions. He must mount the rim in a manner in whichno damage will occur, and he must select the proper weightplacement location for the particular wheel. Due to the vastdiversity of rim designs, it is not feasible to list all possiblecombinations of rim edges and wheel weight clips. Inspectthe rim and available weights and use good judgement in yourselection. Weights should not interfere with any suspensionparts or make contact during rotation. If a weight does makecontact, use tape weights in an alternate location and selectan appropriate alloy mode.WARNING!! Use of improper weight clip attachmentcould result in personal injury or damage to property.Rim surfaces should be clean and weights should beattached securely.The John Bean 7 Series Balancers have an Alloy mode keypadfor selection of the proper location. See Figure 10. Notethat the key itself contains a placement representation of therim and the associated weight location. When an alloy selectionis made the weight mode indicator LEDs change accordinglyto represent the new location. Press whichever buttonclosely resembles the placement desired and the computercalculates the weight amounts and positions. The Mode keypadallows selection of:5 - Alloy 2 plane positions3 - Static/tape weight positions1 - Standard 2 plane dynamic1- Match Balance ModeALU-S MODEThis is a mode similar to the Alloy mode 1 and 2. The differenceis the distance and width parameters are accuratelydefined by the operator for a more exacting weight placement,therefore improving the likelihood of a single spin balance.Follow the procedures outlined below:1. Begin by pressing "F18" and ENTER, display should readAlu-ON. If not press "F18" and ENTER again.2. Select ALLOY 1 or ALLOY 2. The button LED's will blinkindicating the ALU-S mode is active.3. The display reads "d-1" on the left window and the currentdistance reading is in the right window.4. Determine the desired location of the tape-on weights.Using the distance gauge, measure the distance to thefirst (inside) weight location, see Figure 11. The value isrecorded automatically on the 7.6. Enter the numeric valuemanually for model 7.5.5. When the display reads "d-2", repeat step 4 above toenter the distance for the outer weight location plane.6. Enter the rim diameter. NOTE: Do Not make an entryfor the width value, this has been calculated usingthe distance values.7. Lower the Wheel Guard to begin the spin cycle.Figure 10 -- Mode Selection KeypadFigure 11Point of measurementcontactTouch gauge tipto rim as shown8. Rotate the wheel until the location for theinside weight is indicated.9. To accurately find the original location of theinside weight on the rim, pull out the distancegauge and observe the numberschanging in the distance parameter window.When the distance number reaches "0", youhave located "d1" inner weight position.Place the required weight. Repeat for "d2"for the outer weight. Perform a check spin.106Page 15

Multi-Operator ModeThe 7 Series balancers feature an "A/B" selector allowingselection of up to six different operating sessionsto be programmed concurrently. This handy featureallows up to six operators to balance independentlywhile the software "remembers" the wheel informationand the current balancing mode for each. As the "A/B"button is depressed (Figure 12), the memory togglesthrough each operator setup. The button LED displaywill indicate which operator is running. The currentoperator is also indicated on the weight amount LEDwindow as A, B, C etc. (Figure 13). All operator parametersare stored until the machine is powered down.Each time the balancer is turned on the balancer defaultsto the operator "A" mode. The display reads thecurrent operator at the beginning of each spin. Themaximum number of operators using the A/B modekey can be set by pressing "F71" and Enter. Press thedesired number of operators and enter.Stored Parameters (F80-83)This balancer is programmed to allow storage andretrieval of four sets of wheel parameters (Distance,Width and Diameter). This feature is especially usefulfor a shop that balances a large quantity of one typewheel. It may also be simultaneously used by fourindividual technicians by storing the parameters for fourvehicles. Program the balancer as followings:1 . Assign each of the following “F” codes to a particularwheel/Tire or to an individual technician.F 80 -- Technician #1 or wheel #1F 81 -- Technician #2 or wheel #2F 82 -- Technician #3 or wheel #3F 83 -- Technician #4 or wheel #42. Enter the wheel parameters (Distance, Width, andDiameter) in the normal manner.3. Press the assigned "F" Code, followed by pressingthe SPIN button. For example, press F 80 and SPIN.4. The display will change to the following:r = 0 S = 1(recall = 0 Store=1)5. This instructs the operator to press (1) one on thekeypad to "store" the parameters. The parameters aresaved until changed by entering and storing new parameters.Figure 12 -- Multi-operator selectorOPFigure 13 -- Operator is indicated each time theA/B button is pressed.Inch and MillimeterThe operator has the option of selecting parameterinput to be in inches or millimeters.The selector button displays 2 LEDs whichindicate the active mode. When inch modeis selected only parameters in inches canbe input. Metric values can only be entered when "MM"is selected.Ounce and GramOunce or gram can be selected for weightamount readings. Either mode offers equalaccuracy. Select the desired mode bypressing the ounce/gram button. An LEDdisplays the mode selected."F" / Lt TruckThe F/Lt Truck key is used for two functions-- as an activator for programmingFunctions (F-codes), and as the Light TruckMode key.Activate the Light Truck mode by pressing "F/Lt Truck"followed by any mode key.

Pressing "F" scrollsselection down to the next stored location. Press EN-TER to select desired parameters. Press (0) zero onthe keypad to RECALL.Page 18

Calibration of the Wheel ParameterEntry Gauge (F17)If the balancer has not been calibrated before or whenever thebalancer is serviced or relocated, the electronic distance gaugeassembly should be calibrated to maximize accuracy. The balancersystem features two methods of calibration, the first and mostaccurate is the three point F17 Parameter gauge calibration. Thesecond is a simpler and faster but not quite as accurate two pointcalibration, F12. We at John Bean suggest the three point calibrationin the interest of maximizing accuracy.TouchThree Point Calibration - Models 7.6 only1. Press "F-1-7" and "ENTER".2. The display will read "CAL DIS". Rotate the arm a few inchestoward the operator position. Move the gauge rod to the rear edgeof the backplate, make sure the arm touches the backing plate andthe locator ring rests on top of the backing collar. The display willread "CAL PEA" (Parameter Entry Arm) See Figure 14.3. When the display changes to "FLP PEA" flip the distance gaugearm down and touch the locator ring to the bottom of the backingcollar. See Figure 15. The machine will respond after a couple ofseconds then prompt you to return the distance gauge to its normalreturn position while reading "PEA RTN".4. When returned the display will then read "SLU PEA". Install theshaft calibration slug into the tapped hole on the outer edge of thebacking plate. See Figure 16. Rotate the plate and the gauge armto a point where the arm locator ring touches the end of the weight.After a two second pause in this position, the third dimension isentered automatically.5. When the display changes to "PEA RTN" again. Return thedistance gauge to its normal return position. Gauge calibration isnow complete, continue with calibration by performing the "F1"process outlined on page 20.Touch ringagainstbottom ofbacking platePlace ringedge to topof calibrationweightFigure 14Figure 15Figure 16TouchTouch171Manual Distance Calibration (F17) - (Model 7.5)To calibrate, press F17 and ENTER. Display reads "CAL DIS".Move the gauge rod toward the backplate, make sure the armtouches the backing plate. Read the value printed on the gauge rodlabel. Enter this value using the numeric keypad. Press ENTER.The calibration distance is now calibrated. See Figure 17 .Figure 17Page 19

Shaft Calibration of the BalancerThe balancer should be calibrated with scheduled frequency. It is recommended that the balancer becalibrated weekly, if not more often. The programmed calibration monitor will request the operator tocalibrate after every 1000 spins. When prompted, the display will read "Cal Due". Operator can chooseto temporarily bypass the calibration if desired by pressing "Cancel", the program will then allow youto proceed with operation as normal. In areas that have extreme temperature swings or humiditychanges between calibrations, we recommend daily calibration as this will maximize system accuracyunder fluctuating environmental conditions. The balancer should also be calibrated whenever servicework is performed or whenever the unit has been relocated.Calibration Procedure1 - Press F,1 and ENTER (the Green Key with the arrow).2 - The display will read "SLU OFF". Remove the calibrationweight, if installed and press Enter .3 - Lower hood or Press ENTER to initiate the balancerspin cycle.Figure 184 - The display will read "LF PLN". Install the calibrationweight in the threaded hole on the inside of the backing plate.Figure 18.5 - Press ENTER or lower the hood to initiate thebalancer spin cycle. Hood must be lowered to activate spincycle.6 - The shaft will brake to a stop. When the display changesto "rt PLN", attach the cylindrical calibration weight in thethreaded hole from the outside edge. Figure 19.Figure 197 - Press ENTER or lower the hood to initiate thebalancer spin cycle. Hood must be lowered to activate spin cycle.8 - Calibration is then verified by the computer and the display will read "CAL FIN", meaningCALibration is FINished.If the display reads "shf imb" meaning shaft is imbalanced, or If the display reads "CAL ERR" it is likelythat the calibration procedure was not followed correctly. If re-calibration is still unsuccessful contactyour John Bean Service Representative for service or technical assistance.Smart CalibrationThe Smart Calibration feature will automatically prompt a calibration every 1000 spins. Whencalibration is due, the balancer will display "CAL DUE". Press "Cancel" to continue operation until nextpower cycle or press "F1" to calibrate. Check "F72" for the current spin cycle count since last calibration.Page 20

Function or "F"-CodesThe 7 Series digital balancer features a set of programmable"F" codes for balancer control, function customizingand troubleshooting. Some "F" codes offer thesame control as front panel keys. Below is a listing ofthese codes. To select a code function press "F/LtTruck" followed by the desired number. Complete bypressing ENTER.CalibrationF0 - Recalculation without re-spin. Use this function tocompare weights used in various alloy modes.F1 - Weight measurement calibration, dual plane. Thisis the standard calibration process used to compensatefor mechanical and electric variables. See page 8 forinstructions.F17 - Distance gauge calibration. Any time the balanceris moved or serviced, the distance gauge should becalibrated. See Page 9 for instructions.F22 - Calibration Quick Check Feature for 7.6 unitsonly.

Maintenance and CareThe 7 Series balancers require a minimum amount ofcare. However, minor upkeep will prolong the life ofany piece of equipment.Always maintain the work area in a clean and clearmanner. Clutter has the tendency to attract undue dirtand dust. A clean and clear work area is safer.Periodically clean the display surfaces by wiping witha soft rag. Rag should be sprayed with an evaporatingcleaner. Never use a petroleum based cleaner or onewhich leaves an oily residue. Do not use brake cleaner!Maintain the weight tray and cone storage area in aclean clear manner. Occasionally clear out old and discardedweights and accumulated dirt/debris. Disposeof lead weights in a proper manner. Do not spray waterat and avoid splashing at this machine.Never allow unauthorized personnel to operate thebalancer.Do not use Non-John Bean recommended accessoriesand adapters. Tolerances and specifications maynot be to designed standards.Wipe the shaft threads and faceplate occasionally witha bristle brush followed by an oily rag.Calibrate the balancer in a consistent periodic manner.See page 9-10 for calibration instructions. Thebalancer will force a calibration every 1000 spins. Toview the cycle count press "F, 63 and ENTER".TroubleshootingShould you experience some difficulty, follow theseprocedures.Operation Problems:1. Assure proper voltage is supplied to the machine.Do not use extension cords rated for less current thanunit demands. See label on unit back panel for draw.Normally cord should be rated for at least 30 ampscontinuous.2. Inspect on/off switch - does it have the normal tactilefeel?3. Perform a complete calibration. A calibration willoften cure the problem or give a specific error message.Customer Complaint Problems:1. Inspect all surfaces of the shaft and shaft adapters.Note any undue wear, deformations, rust or fit.2. Wheels which have not been mounted according tothe rim design may not balance correctly. Try anothermounting method, or a different cone and rebalance.Make sure the wing nut is tight. Check for rim slippageon the shaft by marking wheel and shaft.3. Check for Wheel warpage or runout. Excessive rimor tire runout may require replacement.4. Inspect the vehicle for worn or loose suspensioncomponents which may lend to a rough or undesirableride.5. A bad vehicle alignment may create poor ride performance.6. Make sure your weight placement is correct.7. Wheel weights should be clean and free of nicks.8. Use the proper type wheel weight clips. Use of improperweights with a rim design may be hazardous topersonal health as well as property.9. The balancer may need to be mounted to a secureconcrete floor surface. There should be no adjacentvibrations which could be transmitted back to the machine.Look for large compressors, hammers, etc.If difficulty still exists -Before calling for serviceHave your balancer model number, serial number,name of business and your telephone number handy.Many times a problem can be corrected or identifiedover the telephone. If service is required, an Equi-ServeTechnician will be computer dispatched to your businessat your request.For USA Nationwide Equi-Serve Service call:1-800-362-8326(1-800-362-8326)or (501) 450-1500 Fax (501) 450-1585See the back of this manual for Worldwide John BeanService and Support locations.Page 22
