12 ? Visualiner 3-D Operator's Manual 1. INTRODUCTION The Visualiner 3-D TM is a revolutionary machine that uses 3-D computer modeling to produce accurate four-wheel alignment readings in less than 5 minutes. A Truly Innovative System Until now, wheel alignment required attaching four electronic measurement heads to the vehicle wheels. The measurement heads have had a data link by electrical wires or by infrared or radio frequency wireless transmission to the main processing computer. This allowed angular measurement of each wheel in relationship to gravity and the vehicle's axles. Using measurement heads required jacking the vehicle, rotation of the wheels for runout compensation, and jouncing of the suspension after lowering to achieve accurate measurements. Electronic measuring heads are subjected to a harsh environment on the vehicle -- dirt, water, vibrations, falling on the floor, etc. The sensors used inside the heads can be quite delicate, requiring frequent maintenance, calibration, or replacement. The electronics in the heads to support the sensors and communications link are subject to failure. With the Visualiner 3-D TM, there are no measurement heads. Instead, four targets are placed on the wheels, and two high-resolution cameras with specially designed lenses, located away from the vehicle, find the targets. From the information gathered by the cameras, the computer uses sophisticated 3-D modelling to calculate the position and orientation of each wheel. The unit then displays all wheel alignment angles in an innovative software format. The system is wireless between the rack, the wheel targets, and the control console. There is no jacking, runout compensation, or jouncing. The Visualiner 3-D TM has been made possible by the recent availability of very powerful cameras and microchips. Several chips are used in parallel to accomplish the high-speed and complex calculations necessary for image analysis. Many years of software development were necessary to achieve the required results. - Page 12 -

13 Visualiner 3-D Operator's Manual? Easy To Operate The Visualiner 3-D TM is the easiest to use computer aligner ever developed. During the alignment, screen navigation is automatic, with visual and text based prompts for the operator. All aligner operations can be performed using five function keys along the top of the keyboard. There are no electronic heads or cables, and no jacking of the vehicle is required. With the Visualiner 3-D TM... Targets are attached to the wheels Camera images of the targets are taken The vehicle is moved approximately 8" (20 cm) back and another set of images is taken The vehicle is moved approximately 8" (20 cm) forward and another set of images is taken. The computer then calculates the axis about which the wheels rotated. From this, the Visualiner 3-D TM calculates toe, camber, thrust angle, and setback. These readings are displayed on a unique, 3 dimensional screen where adjustments can be made. Adjustment help for each angle measured can be obtained as well. Steering angle measurements are easy -- simply begin to turn the wheel to the left. The software senses the turn and automatically switches to the Steering Angles Measurement screen. This screen is used to calculate caster, steering axis inclination, toe-out on turns, and maximum turn angle utilizing one turn left and right -- without touching the keyboard. Additional Visualiner 3-D TM functions are easily found in one spot called the Quick Access menu, always accessible by pressing the F4 function key. Major Features No electronic measuring heads, gauges, or gravity devices The Ultimate "Cordless" System No need to raise the vehicle to compensate for wheel runout -- very important on all wheel drive vehicles (i.e. Audi Quattro) and on stiff suspension vehicles (i.e. Mercedes, Lexus) for accurate readings Intuitive software -- no complex menu systems Fast acquisition of camber, toe, thrust angle, and setback values on all 4 wheels - Page 13 -

Caster, SAI, TOOT, and Maximum Turn Angle measured with one turn Direct measurement of Caster and SAI A level alignment rack is not required Extensive vehicle adjustment help graphics featuring VODI (Vehicle Orientation Directional Indicator) to help visualize adjustment location Aftermarket rear shim programs Jack and Hold mode for camber and caster corrections with the wheels unloaded 20 year alignment specification database Alignment History automatically saves every alignment to its database Printer and keyboard standard The Visualiner 3-D TM Four-Step Alignment Using 3-D modeling and sophisticated computing power, the Visualiner 3-D TM produces accurate alignment readings in four simple steps: 1. Drive the vehicle onto the lift and position on the turntables. 2. Mount the targets on the wheels. The monitor displays the status of each target and prompts you to proceed to the next step. 3. Roll the vehicle backwards about 8 inches (20 cm) until the display prompts STOP, and then forward returning to the turntables. This is all the computer needs to accurately calculate toe, camber, thrust angle, and setback for all four wheels, which is displayed on the monitor. 4. You can now print out a basic alignment report or measure Caster and Steering Axis Inclination (SAl), as well as Toe Out On Turns and Maximum Steering Angle if desired. Simply remove the turntable pins and rotate the steering wheel first in one direction, and then the other. The 3-D Aligner tells you where to stop, depending on which measurements you want. You can even get all four measurements in one side-to-side steering sequence. - Page 14 -

15 Visualiner 3-D Operator's Manual? 2. SYSTEM OVERVIEW Components The Visualiner 3-D TM consists of the following components: The Computer Console which houses the computer, a monitor, printer, and keyboard The Beam and End Pod assembly, which contains the two high resolution cameras and camera control electronics Four target and wheel clamp assemblies A Remote Display unit Accessories such as the steering wheel holder, the brake pedal depressor, adjustable wheel chock Software and User Interface The Visualiner 3-D TM screens provide the necessary information in a easy to understand, visually pleasing graphical format. Icons are used heavily, with text added when necessary for further explanation. Most software navigation during the alignment is automatic with clear prompts for the operator. The user interface screens can be grouped into four general categories: Vehicle identification screens Customer information screens Alignment screens Vehicle help screens These four groups of screens are linked by a powerful database contained within the software. Computer Console The Computer Console consists of the computer control system, the 17" SVGA monitor, the printer and keyboard, and provides a storage area on the side for the target and rim clamp assemblies (see Figure 1). Risk of electrical shock. There are high voltages present inside the Main Console unit. Service should be performed only by authorized personnel. See warning notice in safety section of this manual. Computer Control System The Visualiner 3-D TM uses a PC-based control system. The computer, which is located inside the lower cabinet, includes a Pentium CPU, a CD-ROM drive, a 3-1/2" floppy drive, a hard drive, and 16 megabytes of RAM. A keyboard is used for operator interface. The computer used in this product is specifically designed for this application. Do not upgrade or replace components, add peripherals, or tamper with settings. Doing so may render the unit inoperable. A 17" super VGA monitor prompts the operator and displays the alignment information. A high quality printer is used to print alignment results. Power Requirements The Visualiner 3-D is a highly sophisticated computer system that requires an adequate power supply. 1. The Visualiner 3-D camera power supply is selectable for 110/220 volt 50/60Hz single phase input power. This will be preset at the factory depending on where the aligner is to be shipped. The tolerance for incoming power is +10%. 2. The PC power supply is also selectable for 110/ 220 volt 50/60Hz. This is also preset at the factory. 3. Good earth ground is a requirement for proper operation and safety. Do not operate with a plug that has had the ground lug cut off. If an extension cord is required, use one of adequate size to handle the current demands. 4. As with all electronic equipment, we recommend the 3-D Aligner be protected from voltage spikes and using an appropriate surge protector on the incoming power line. For convenience, consider a power strip with surge protection built-in. These can be obtained from a computer or electronics supplier. - Page 15 -

16 ? Visualiner 3-D Operator's Manual Power Controls Main Console On/Off Switch (rear cabinet) Camera End Pods Monitor Beam Camera System On/Off Switch Printer Keyboard There are two (2) main power ON/OFF switches that must be turned on to initiate the system. The first, which powers the camera system, is located on the bottom right of the camera support beam, adjacent to the incoming power cord. The other powers the computer console, and is located on the rear of the mobile cabinet. User-replaceable fuses are adjacent to the power ON/OFF switches in both locations. These fuses protect both line inputs to the aligner. Note: It is recommended the camera power switch be turned on prior to powering the computer console. This insures the computer establishes communications with the camera system. The are also power switches located on the monitor and the computer (inside the lower cabinet) -- leave these ON at all times. Beam and End Pod Assemblies Clamp/Target Storage Lower Cabinet Door Figure 1 -- Visualiner 3-D Components The beam assembly is mounted on two column supports. The two end pod assemblies are mounted on either end of the beam assembly. Each end pod houses a high resolution camera, with an LED array around the perimeter of each camera lens. During an alignment, the LED s flash to assist the cameras during wheel target location and tracking. In addition to supporting the end pod assemblies, the beam assembly provides an enclosed route for the wiring between the cameras and the computer control system. Wheel Targets and Clamps The wheel targets are attached to wheel clamps for easy mounting on the wheels (see Figure 6 on Page 20). The front targets are smaller than the rear targets. The wheel targets have a special photo-reflective pattern on them and are protected by glass. The assemblies are passive and contain no electronics. Remote Display Unit The Remote Display is useful for making adjustments when it is difficult to see the monitor. Refer to Appendix A for instructions on Remote usage. - Page 16 -

17 Visualiner 3-D Operator's Manual? 3. GETTING STARTED Power On Sequence The Visualiner 3-D TM two main power switches are located on the bottom of the Camera Beam and on the back side of the Computer Console. Turn the camera beam power switch ON, then the computer console switch ON to begin the power-on sequence. Once the initial computer information is loaded, a "Start Menu" appears. This menu has selections for a variety of functions, most of which are for manufacturing and field service use. The Start Menu stays on-screen for 10 seconds -- if no keyboard keys are pressed. After 10 seconds the Visualiner 3-D TM software begins its loading process. If a key is pressed while the Start Menu is displayed, other functions on the menu can be activated. The first entry, Align Vehicle, exits the Start Menu and begins the alignment program. See Appendix D for details on Start Menu functions that may be useful to the operator. During software loading, the LED arrays in the end pod assemblies should illuminate, and after approximately 1 minute they should begin to flash. It takes less than two minutes for the Visualiner 3- D TM software to fully load. It is acceptable to leave the Aligner power ON throughout the work day, and turn it off at the end of the day. New Alignment Screen Figure 2 New Alignment Screen The New Alignment screen is displayed at the end of the Visualiner 3-D TM software power-on sequence (Figure 2). This screen is also displayed when Start New Alignment is selected from the Quick Access screen (Figure 3). The New Alignment screen is where each new wheel alignment is started. Quick Access Screen The Quick Access screen (Figure 3) is the Visualiner 3-D TM main navigation screen. This screen gives you access to all aligner functions. To get to this screen at any time, simply press the Quick Access (F4) function key. Use the up and down arrow keys to move the cursor around the icons. An Information Box at the bottom of the screen describes the icon's function. When the desired icon is highlighted, press the Select (Enter) key. The Exit (ESC) key will return you to the previously displayed screen. Figure 3 Quick Access Screen - Page 17 -

Note also that the keyboard's standard Enter keys and Up/Down arrow keys and have the same functions as F1-F3 respectively. Positioning the Vehicle on the Lift Proper vehicle positioning on the alignment lift is an important step for safety and accuracy. 1. Make sure the front turntable and rear slip plate locking pins are in place. Note: Steps 2-5 are recommended to make sure the front tires are placed in the center of the turntables. 2. Drive the vehicle onto the alignment lift and stop just before the turntables. Take care to insure the vehicle is centered on the runways. 3. Place the vehicle in park (or in gear on a standard transmission), turn the ignition off, and set the parking brake on. Place wheel chocks behind the tires to prevent rolling. - Page 18 -

19 Visualiner 3-D Operator's Manual? Failure to use the wheel chocks can allow the vehicle to roll off the rack/lift. 4. Position the turntables as needed to insure the tires will be centered. 5. Drive the vehicle forward onto the center of the turntables. Alternative Method: This method extends turntable life due to relief of load and stresses encountered when the brakes are applied (or acceleration on a FWD vehicle). 5A. Place the vehicle in neutral, release the parking brake, and pull or push the vehicle forward onto the turntables. Reposition the wheel chocks, place the vehicle in park, reapply the parking brake. To avoid personal injury or damage to property, follow the rack/lift manufacturer's operating and safety procedures. Figure 5 Position Vehicle on Turntables 6. Raise the alignment lift so that the targets, when attached, will be in the cameras' "field of view". Lower the lift onto its mechanical stops. 7. Place the transmission in neutral and release the parking brake just before beginning the rolling Vehicle Positioning process. Attach the Targets The targets are attached to the wheels using the self-centering wheel clamps. The large targets go on the rear wheels, the small targets on the front. They are interchangeable left to right. There are several methods of attachment depending on the wheel lip configuration. The integrated claws provide the versatility needed to grab virtually any wheel. The claws can be rotated to adjust for different wheel configurations. Claws may have sharp edges. To avoid personal injury, use caution when working with wheel clamps. The clamps should be installed in a straight-up vertical manner (knob at the top), unless low rear fender skirts prohibit this. For these vehicles, the rear target can be rotated 90 degrees on the clamp. - Page 19 -

20 ? Visualiner 3-D Operator's Manual Claws Tightening Knob Target To accomplish this, loosen the arm located on the back side of the target, then rotate the target as far as possible. Tighten the arm to secure the target, and mount the clamp horizontally on the wheel. Use the mounting method that provides the greatest security to keep the target from falling off the wheel. Most wheels can be grabbed from the outside in by placing the claws between the bead of the tire and the outside edge of the rim. Use the following steps: Figure 6 Clamp and Target Assembly 1. Extend the clamp outwards to a size larger than the rim by turning the knob counter clockwise. 2. Place the upper claws on the outside of the top of the rim. Push the claws in between the tire bead and the rim. It may be necessary to "pop" the upper clamp bracket with the palm of your hand to seat well. Note that it is not necessary for the clamp to be mounted perfectly vertical on the wheel. 3. Tighten the clamp by turning the knob clockwise until the lower claws engage the rim. 4. Push the lower claws into place. Again, it may be necessary to pop them in further for security. Continue tightening the knob until secure. 5. Test the security by pulling outwards on the clamp. If it comes off easily, reattach the clamp or select an alternative mounting method. To grab the wheel from the inside out using the outer lip of the rim, use the following steps: 1. Extend the clamp inwards to a size smaller than the rim by turning the knob clockwise. 2. Place the lower claws on the wheel lip at the bottom of the wheel. If a wheel weight is in the way, move the clamp slightly to clear the weight. It is not necessary to be perfectly vertical. 3. Tighten the clamp by turning the knob counter clockwise until the upper claws engage the rim. Continue to tighten until the clamp is secure. 4. Test the security by pulling outwards on the clamp. If it comes off easily, reattach the clamp or select an alternative mounting method. - Page 20 -

21 Visualiner 3-D Operator's Manual? 4. PERFORMING A WHEEL ALIGNMENT New Alignment Screen The New Alignment screen (Figure 7) is where all alignments begin. If the automatic customer and alignment history database is used, or if a customer printout is being made, start with New Customer. If no customer information is desired, move directly to Select Vehicle (page 22) for specification reference. Once the vehicle is selected, go to Align Vehicle to begin the alignment process (page 23). Inspect Vehicle generates a form used for manually checking the vehicle's suspension and steering. Customer Information Screen This screen is accessed by selecting New Customer from the New Alignment screen, or by selecting Customer Information from the Quick Access screen. The Customer Information screen (Figure 8) allows entry, storage, and editing of customer and vehicle specific information. This information is stored in a customer database, quickly accessible when the customer comes in for their next alignment. The customer database information is accessed by simply entering the vehicle licence number or the customer last name. The database allows multiple vehicles to link to a single name. Use the up and down arrow keys to move about the screen to the various fields. Use the keyboard to enter the customer information. The tab, backspace, and delete keys are also functional on this screen. The 6 icons along the bottom have the following functions: Vehicle Selection -- goes to the Vehicle Selection screen Delete Registration -- deletes the displayed customer record from the database Next Registration -- displays the next vehicle for this customer (if applicable) Next Name -- goes to the next customer name in the database Alignment History -- view the alignment history for the vehicle selected EXIT -- store information in the database Figure 7 New Alignment Screen Figure 8 Customer Information Screen The Make, Model, and Year fields cannot be changed from this screen. They are automatically updated by the Vehicle Selection screen. After - Page 21 -

22 ? Visualiner 3-D Operator's Manual entering the desired customer information, choose Vehicle Selection to proceed to enter the vehicle information. If the correct Make, Model, and Year is already displayed, select EXIT to proceed with the alignment. Vehicle Selection Screens Figure 9 Vehicle Make Selection The Vehicle Selection screen (Figure 9) is where the vehicle is chosen, and is the source of specifications for comparison to the measured values. Vehicle Selection is accessible from the Customer Information screen, or by choosing Select Vehicle from the Quick Access or New Alignment screens. First identify the vehicle by make, then model and year (Figure 10), and in some cases, by sub-model. Use the up and down arrow keys, or enter alpha characters to move to the correct vehicle information. When the desired information is highlighted, press the Select (Enter) key. When the Vehicle Selection sequence is complete the software exits to the point where the information entry was started. Figure 10 Vehicle Model and Year On some trucks, Vehicle Ride Height and/or Frame Angle entry screens (Figure 11) appear if required by the manufacturer to calculate proper camber and caster specifications. The screen illustrates where on the truck to make the required measurements. Make the entries on the screen according to measurements made on the vehicle. Figure 11 Ride Height Entry - Page 22 -

23 Visualiner 3-D Operator's Manual? Vehicle Positioning Sequence Select Align Vehicle from the New Alignment screen. The Target Acquisition screen (Figure 12) is displayed. This screen displays the status of each target and prompts the operator to proceed to the next step. The vehicle is then moved approximately 8" (20 cm) causing the targets to rotate about the spindle. The computer compares the initial target positions with the final target positions to calculate the axis of rotation for each wheel. When the Target Acquisition screen is first displayed, the cameras search for the wheel targets, and the graphic images of each wheel target are displayed in red. As the cameras locate each of the wheel targets, the target graphics change from red to blue. When all four wheel targets are located, the first Vehicle Positioning screen is displayed. Figure 12 Target Acquisition Screen The Vehicle Positioning screen displays orange arrows that prompt you to move the vehicle backwards, approximately 8 inches (20 cm). See Figure 13. Find a spot under the front of the car to push backwards. The graphic image on the screen follows the vehicle's movement as you roll the vehicle backward and the arrow decreases in size. Figure 13 Vehicle Positioning, Push Vehicle Back Too Far Back If the vehicle is moved too far in one direction, a red arrow will appear prompting you to move the vehicle the other direction a small amount. See Figure 14. Figure 14 Vehicle Pushed Too Far Back - Page 23 -

24 ? Visualiner 3-D Operator's Manual A small red STOP sign will prompt you when the necessary backward wheel rotation has been reached. See Figure 15. Hold the vehicle steady until the stop sign disappears. Figure 15 Stop and Hold Vehicle Steady When the aligner is ready, the screen displays a green arrow to prompt you to move the vehicle forward and return it to its starting position (Figure 16). Grab the vehicle where it is convenient and roll it forward onto the turntables where it began. Figure 16 Vehicle Positioning, Pull Vehicle Too Far Forward If the vehicle is moved too far forward, an arrow will appear directing you to move the vehicle back a small amount. See Figure 17. Figure 17 Vehicle Pulled Too Far Forward - Page 24 -

25 Visualiner 3-D Operator's Manual? A large red STOP sign will prompt you when the wheels have returned to their original start positions. Figure 18. Hold the vehicle steady until the stop sign disappears. Wheel Wobble Message The Visualiner 3-D TM may detect wheel wobble during positioning (Figure 19). The screen indicates which wheel wobbled. To ensure high accuracy, we recommend restarting the positioning sequence if wheel wobble is detected. Select the RESTART icon to return to the Target Acquisition screen to repeat vehicle positioning. If the CONTINUE icon is selected from the wheel wobble prompt, a warning message is displayed (Figure 20), with the same choices given. Here are some of the reasons for wheel wobble and tips for correction: Figure 18 Stop, Hold Vehicle Steady 1. When driving the vehicle onto the alignment lift it is possible you turned the steering wheel to get centered on the turntables. This causes stresses to be built up in the linkage. As the vehicle is rolled back and forth during positioning, these stresses relax and cause the wheel to wobble. If you know the vehicle was steered before it reached the turntables, roll the vehicle back and forth a few times before attempting the positioning sequence. 2. Make sure the wheels do not experience any external disruptions as they move. Check for a gap or depression between the front turntables and the runway surface. Check for items that may cause a bump as the wheels roll. Figure 19 Wheel Wobble Detected 3. Check the wheel clamp mounting to make sure the claws are secured onto the wheel. Any looseness could result in wobble. 4. Avoid jacking the vehicle prior to performing positioning. To check steering components, we recommend the "Dry Park Check" procedures (see Appendix C). If it is necessary to jack the vehicle, roll it back and forth a couple of times to allow the suspension to settle prior to the positioning sequence. 5. Make sure the front wheels are pointing straight ahead. If not, the wheels will tend to move towards the center position as the vehicle is rolled back and forth, causing the wobble message. Figure 20 Wheel Wobble Warning Message - Page 25 -

26 ? Visualiner 3-D Operator's Manual 6. Worn suspension or steering components, such as bad wheel bearings, worn tie-rod ends, a loose gearbox or rack and pinion, may cause the wheel to wobble as it rolls. 7. A vehicle with an excessive amount of rear toe (1 o or more) may experience wheel wobble due to excessive scrubbing forces. TIP: If a vehicle is encountered that gives repeated wheel wobble, use the Individual Wheel Positioning function (Page 39). Lock Brakes and Pull Turntable Pins Figure 21 Lock Brakes Screen When vehicle positioning is complete, a screen briefly appears telling you to install the brake pedal depressor and pull the turntable pins (Figure 21). Note: This screen prompt can be disabled in the User Preferences setup. Center Steering Figure 22 Center Steering When vehicle positioning is complete, the aligner checks the steering angle of the front wheels. If the wheels are not reasonably centered, the Centering Steering screen appears (Figure 22). Arrows adjacent to the steering wheel displayed in the lower portion of the screen prompt the correct direction to rotate the steering wheel in order to center the steering. The reason for centering the steering angle at this point of the alignment is to assure correct before front toe readings. Once the center position is attained, the screen will automatically exit. Once the wheels are turned straight ahead, the next screen to appear is either the Main Alignment screen or caster measurement screen, depending on the User Preference setup. Main Alignment Screen The Main Alignment screen is automatically displayed after the vehicle positioning sequence is successfully completed (Figure 23). From the readings taken during vehicle positioning, the aligner accurately calculates toe and camber for all four wheels, as well as thrust angle. This screen provides a graphical representation of the wheels with analog and digital alignment readings. In addition, the screen provides selectable icon fields. Figure 23 Main Alignment Screen See Page 31 for additional information on how to read, understand, and use the various functions on the Main Alignment screen. - Page 26 -

27 Visualiner 3-D Operator's Manual? Steering Angles Measurement Begin steering measurements from the Main Alignment screen by rotating the steering wheel in either direction. As you rotate the steering wheel, the Visualiner 3-D TM tracks the wheel targets. When the steering wheel is rotated more than 5 degrees, the Steering Measurement screen is automatically displayed. Seven steering measurement position icons are displayed across the top of the screen, three icons for right-turn measurements, three icons for left-turn measurements, and a center steering wheel icon (Figure 24). The icons indicate the steering positions for measuring caster and steering axis inclination (SAl) simultaneously, toe-out-on-turns (TOOT), and maximum steering angle. As you rotate the steering wheel toward each measurement position, a yellow cursor at the top of the screen tracks the wheel movement, and a red status bar appears below the desired icon. The left and right caster and SAl measurement positions are at approximately +10 and -10 degrees, while the TOOT positions are at approximately +20 and -20 degrees. The maximum steering angle positions vary, depending on the vehicle. Left Toe Out On Turns Left Maximum Turn Angle Status Bar Left Caster and SAI Center Steering Right Caster and SAI Figure Steering Angle Icons Cursor Completion Box Right Toe Out On Turns Right Maximum Turn Angle Arrows adjacent to the steering wheel displayed in the lower portion of the screen, prompt the correct direction to rotate the steering wheel. A numerical readout in the center of the steering wheel indicates the steering angle in degrees. See Figure 25. As the wheels approach each measurement position the red bar below the icon changes to yellow. When the wheels reach the correct position, the bar turns green, and a red stop sign appears on a green background in the center of the screen. As the measurement for each position is complete, a box appears around that icon and the red stop sign disappears. The Visualiner 3-D TM prompts you where to stop, depending on which measurements you want. For example to measure caster and SAl only, move the wheels from one caster position to the other caster position, and then return to the center steering position. To measure caster, SAl, and TOOT, move the wheels from the caster position to the adjacent TOOT position, then to the other caster and TOOT positions, and then return to the center steering position. You can even get all four measurements in one side-to-side rotation sequence. Numeric Turn Angle Turn Direction Indicator Figure Steering Angle Measurement Screen - Page 27 -

28 ? Visualiner 3-D Operator's Manual During steering measurements, the Aligner may briefly lose track of one or more wheel target. When this occurs, wheels displayed on the lower-left and lower-right will turn red to indicate the lost wheel targets. Losing the rear targets during steering angle measurements does not cause a problem. When the front wheel targets are lost, stop steering rotation until the aligner finds the lost targets. When centering the steering wheel at the end, the Aligner msut see the rear in order to update toe and thrust angle. Stand clear of all targets when the stop sign appears to display the Main Alignment screen. Measuring Steering Angles Figure 26 First Caster Measurement Screen 1. To measure the various steering angles, use the following steps: 2. IMPORTANT: Firmly install the brake pedal depressor (if not previously installed) to lock the brakes to keep the wheels from rolling. It is advisable to start the car when locking the brakes to enable the power assist function. Set the parking brake. 3. Begin the measurement of steering angles by turning the wheels to the right or left. It is easier, faster, and more accurate to turn the wheels using the steering wheel as opposed to using the tire. Figure 27 Stop Sign Appears at 10 o, Hold Steady 4. The screen automatically switches to the steering angle measurement screen. Figure 25.? Caster and SAI 5. The status bar is positioned under the Caster/ SAI icon first. The status bar turns from red to yellow as the angle approaches 10 o. At approximately 10 o the bar turns green. Figure 26. Figure 28 Completion Box Appears 6. When the steering angle reaches 10 o, a red stop sign appears above the steering wheel (Figure 27). Stop turning the wheel and hold steady for a few seconds. A white box will appear around the Caster/SAI icon and the stop sign will disappear (Figure 28) when the measurement is complete. - Page 28 -

31 Visualiner 3-D Operation Manual Wheel Roll Message If the aligner detects any wheel roll during the steering angle measurements, a error message appears (Figure 35). We recommend restarting the steering measurements if this occurs. Select RESTART CASTER and the software begins a new steering angle measurement sequence. Wheel roll can usually be corrected by firmly installing the brake pedal depressor. On many vehicles it is necessary to start the engine to enable the power brakes in order to keep the wheels from rolling. Figure 35 Wheel Roll Message Note: If Toe Out on Turns and Maximum Turn Angle have been measured, and "wheel roll" appears, repeat only the caster/sai measurement. The other angle values will not be lost. When the desired steering measurements are completed, the software prompts the operator to center and lock the steering wheel before performing any alignment adjustments (Figure 36). After a few seconds the Visualiner 3-D TM automatically returns to the Main Alignment screen. Note: This prompt screen can be disabled in the User Preferences setup. Figure 36 Center and Lock Steering Wheel This completes measurement of all steering angles. Remember, you can re-measure them at any time by simply turning the steering wheel. - Page 31 -

The screen appears as a vehicle with the body lifted off, viewed from the rear and above. Review the figure above to become familiar with the screen layout and functions. Each wheel angle has a numeric reading as well as a graphical meter display indicating directional orientation and relationship to specifications. Camber meters, located along the top of each tire, have a line that indicates camber relative to the preferred specification. Toe meters, projected onto the ground in front of each tire, have an arrow that indicates the toe angle. Caster and SAI are simultaneously represented in a two dimensional meter format by a projection in front of each wheel. The front to rear component represents caster and the left to right component represents SAI. The numeric value for caster is directly above the meter. SAI (and included angle) are viewed numerically on the Alignment Readings screen. When a meter is green, the reading is within specifications. When the arrow is centered within the green it is at the preferred value. A yellow or a red meter indicates the reading is out of spec (yellow is "close"). The red meter contains a green band, indicating the direction of needed change. A gray meter indicates there is no specification for that angle. All numeric readings on this screen are actual live measurements. If any angles require correction, make sure the brake pedal depressor is engaged and the steering wheel is centered and locked, then simply begin the adjustment. As the angles change the display will update to reflect the new readings. The numeric values change and the meter indicators move in the direction of change. - Page 32 -

33 Visualiner 3-D Operator's Manual? Jack and Hold Some vehicles require the weight to be removed from the suspension to ease caster and/or camber corrections. On others, access to the adjustment points is easier with the wheels elevated. The Visualiner 3-D TM has a Jack and Hold mode to accomplish this. To enter this mode, use the Up/ Down arrow keys to scroll through the screen icons until the white selection box is over the Jack and Hold icon located in the upper right corner of the screen (Figure 37). Press Select (Enter), raise the vehicle (using rigid jacks), and press Enter to continue. The screen appears the same if the vehicle was not elevated. Make the necessary alignment angle corrections for camber and caster. Note the Jack and Hold icon changes (car up in the air) to indicate the screen is displaying elevated readings (Figure 38). When adjustments are done, select the icon again and follow instructions to lower the vehicle. Figure 37 Select Jack and Hold Mode Important Note: Do not adjust toe while the vehicle is elevated. Do not print the results of the alignment with the vehicle in the Jack and Hold mode. Final toe angle information will be incorrect. Printing Alignment Results Move the selection box to the Printer icon on the left side of the screen. Press Enter (Select) and a detailed printout appears on the printer. See Appendix B on Page 53 for details of how to read the printout. Auto-Caster Mode The aligner is designed to automatically measure steering angles whenever the wheels are turned past 5 degrees (see page 27). In some cases, this may not be desirable. By moving the selection box to the Auto-Caster Mode icon, and pressing Select (Enter), this automatic feature can be turned off, as indicated by the icon. When Auto-Caster is off, turning the wheels does not begin the steering angle measurement process. Press Enter again to enable the Auto-Caster feature.
