6 1.Introduction This manual provides operating instructions and information required to operate the CCD wheel alignment computer equipped with the dsdemo.exe graphical alignment software. It is recommended to read the manual in the order presented. The Quick tour chapter will provide the basic information needed to operate the aligner through a total four wheel alignment. Notation: All actions are printed as bold type so it is easily understood which action is required by the operator. Between the bold type items are illustrations and explanatory information to guide you through the operation. The manual assumes customers are already familiar with the basics of wheel alignment. When reading the Quick tour chapter, minimum information is provided about how to operate the aligner. More detailed information can be found by reading the sections referenced to in italics. These references should be read as needed for additional information to the instructions presented. 1.1 Safety precautions Read and follow all cautions and warnings printed in this manual and on the equipment. Misuse of this equipment can cause personal injury and shorten the life of the equipment. This unit must be plugged in to properly ground outlet. Do not cut off the grounding prong on the AC power cord. If using a ground adapter, be sure the pigtail is grounded to the power receptacle. If an extension cord is needed, use a three-wire type with the grounding circuit in good condition. Grounding this equipment is essential for its safe and correct operation Use a separate outlet for the mains supply suited for computer equipment. Do not connect lifts, tire-changers, welding-machines etc. to the same outlet since this may cause the aligner to malfunction or cause seriously damage to the aligner. Turn off the power before moving the system cabinet. The aligner is equipped with a hard disk which may be damaged by vibration. When the power is off the read/write heads are parked and the unit may be moved safely. The equipment should be stored and kept in a dry condition. The equipment is not weatherproof and should not be used outside in rain or snow. Always use wheel chocks in front of and behind the left rear wheel after positioning a vehicle on the rack.

7 1.2 Power interruption The equipment constantly stores the state of the measurement and the values recorded. If AC power to the system is interrupted, or if the unit is turned off, any measured alignment information will not be lost. When power is restored and the program is restarted, operation will resume from the point at which the power failed.

Press Next Step, when the vehicle has been loaded. The screen will change to the Vehicle information screen. 3.3 Vehicle information This screen shows different information regarding the correct setup of the vehicle for alignment measurement as per different vehicle model. See the picture below, which ask the operator to check the air compress of four tyre.

14 Position the vehicle on the alignment rack with the front wheels centered on the turntables and the rear wheels on the slip-plates and apply the parking brake. Notation: In order to avoid flushing of elec. turntables and slide- plates with the floor or the platforms of the lift, it is recommended to place the slid-plates and turntables after the run-out compensation has been performed and then lower the vehicle. Otherwise damage to the elec. turntables may occur. Before lower the vehicle, take out the lock pin of the elec. turntables, and push the elec. turntable inward for 1-2cm, in this way, the wheel will be posited in the center of the elec. turntable after lower the wheel. Lift the vehicle to the alignment height. Notation: In order to ensure correct alignment, the alignment rack must be in level in transverse and longitudinal directions. In left and right the level difference is not allowed over 2 mm, in front and back the difference is not allowed over 3 mm. Check for correct tire size and pressure. Check for weakened coil springs (vehicle may be leaning to one side). Turn the steering wheel from side to side and feel for excessive play. Check control arms and tie rods for possible wear or damage. Check ball joints and bearings for wear or damage. Visually inspect rims for signs of damage or excessive run-out. Badly damaged rims must be replaced. Press Next Sept when the vehicle has been set up correctly. The screen will change to the Run-out compensation screen.

15 3.4 Ready for run-out compensation This screen initiates the actual measurement of the vehicle. Before performing the run-out compensation the measurement must be prepared in accordance with the following procedures: Attach the clamps to the rims and check that the clamps are secure. The clamps can be fastened to the rim either from the inside to the outside or vice versa by turning the star grip. For alloy rims special adaptors are available. Level the units according go the electrical levels and tighten the locking pins. Check for infra red beam are shaded. Connect the electronic turntables. When the run-out compensation procedure has been initiated, the lamps on all four units should light continuously red. If this is not the case you should either initiate a new measurement from the main menu, or you should push the ZERO button on a measuring unit or on the screen to reset the current compensation values. Lift the vehicle. The compensation may be started with any wheel. If all four wheels cannot be jacked during compensation, it can be preferable to start with the wheels held by the handbrake, in this way ensuring that the vehicle will not roll away when lowered. Lift the vehicle 3cm off the ground of the lift. When compensating one of the drive wheels beware that the other wheel does not rotate. It may be necessary to chock the wheel to prevent it from rotating. If a measuring unit is removed from any wheel this wheel must be compensated again when remounted.

16 3.5 Start Run-out compensation The compensation may be started with any wheel. The process is as follows: 1.Loose the locking screw on the unit and turn the wheel until the clamp is in vertical position and the star-grip in upper position. 2.Set the unit go horizontal position. (See the picture above, the line around the yellow lamp will turned into green.)the arrow at the 90 degrees position will change the position. Simply click on the picture above, it will turn clockwise, we will complete a repair of wheel four times like this and again and again. 3.Turn the wheel 90 degrees clockwise until the clamp is in the horizontal position with the star-grip to the right. 4.Press the compensation button. The arrow at the 91 degree position disappear, appear at the 180 degrees position. 5. Turn the wheel 90 degrees clockwise until the clamp is in the vertical position with the star-grip in the lower position. Press the compensation button.

17 6. Turn the wheel 90 degrees clockwise until the clamp is in the horizontal position with the star-grip to the left. Press the compensation button. 7.Turn the wheel 90 degrees clockwise until the clamp is in the vertical position with the star-grip in the upper position. Press the compensation button. The screen shows a green circle to indicate, that the run-out compensation has been completed for this wheel. Notation: Fig

18 If the screen shows a red value, it indicates, that the wheel has excessive run-out. The angle shown is the run-out, while the line indicates the direction of the maximum run-out. The maximum run-out accepted without warning can be changed in the program setup. Although the aligner will calculate the correct alignment angles even though the wheel has excessive run-out, it should be checked if all claws on the clamp are mounted correctly or if the rim is damaged. Repeat this procedure for the remaining wheels. Notation: Secure the installation of the clamp. When the wheel has been compensated, the wheel may be rotated to any position without any influence on the measuring accuracy. The compensation procedure can be repeated for any wheel by pressing the compensation button on the corresponding unit. The lamps on the unit turn red and the procedure can be repeated for this wheel. To restart the compensation procedure for all wheels press the ZERO-button on a measuring unit or on the screen. Lock the brakes with the brake pedal depressor. Notation: If the handbrake has been pulled during the compensation, it should be released during the measurement, to ensure the highest possible accuracy. Pull the locking pins on the turntables, loosen the locking screws on the sliding plates and push the plates inwards 1-2cm. Lower and bounce the vehicle. Level and lock the units. Press Next Step when the run-out procedure has been completed. The screen will change to the Caster measurement. 3.6 Caster measurement This screen is used for initiating the measurement of caster, kingpin, toe out on turns and max. lock angle. When the ZERO-button is pressed, the progress bar at the right down corner show the progress, the camber and toe values are stored as the before adjustment values. In the following picture, we will continue to measure:

19 The bar graph shows the vehicle driving direction. When steering straight ahead, it always check that the measuring heads are in level. Steer the front wheels until the bar graph turns green and the arrow is in the centre position. Notation: If using mechanical turntables remember to reset the scales on the turntables before pressing the ZERO-button. Press the ZERO-button. Turn the steering wheel to -10 o position, see the picture.

20 When the ZERO-button has been pressed, turn the steering left or right to measure caster and max turning angle. When you turn steering wheel the screen will appear the ray blocked. You take no notice of it,and still turn steering wheel. The steering scale on the screen showing the present steering position. Turn the steering wheel to right to finish reading the data, you also need to turn the steering wheel to left to read another half data. During the swing, the caster, KPI, toe-out-on-turn, inclusive angle, max. lock angle can be measured. After the caster measurement has been completed, all measured angles are stored as the before adjustment values. These values cannot be changed until New measurement button is selected. When the wheels have been set to the straight ahead position the screen automatically changes to the Measurements screen. 3.7Measurement before adjustment The screen Measurements shows the result of the wheel alignment before the vehicle is adjusted.
