2. Overview about the wheel aligner
2.1 General
The wheel aligner was designed to measure the axle geometry and compare it with the default values of the vehicle
manufacturers. It also gives the user instructions on how to make appropriate adjustments for best steer ability and lowest tire
w e a r .
2.2 Function and properties
•Complete test: The Wheel Aligner can be used to measure the most wheel alignment
Parameters, such as front wheel toe-in, front wheel camber, caster, Kingpin inclination,
Rear wheel toe-in, rear wheel camber, thrust angle, wheelbase difference, tread
Difference, axle offset, front wheel setback and rear wheel setback, etc.
•Complete databank: wheel alignment data of over 20,000 vehicle models is stored in the system. User can also add
new data to the databank.
•Adopts the charge coupled device (CCD) with high resolution, infrared 8-beam and full
Loop measurement, accurate and stable, Bluetooth wireless communication mode, no
Data transmission influence.
•Based on the thrust line to realize the real alignment measurement.
•Front alignment test function: user can select the alignment mode flexibly. Only two
Probe rods are mounted can the emergency alignment measurement for the front wheels are performed.
•The sensor heads are individually interchangeable. After changing one of the sensor
Heads, the other three needs not to recalibrate, which makes the after-sales service
more convenient.
•Fully intelligence. The system can automatically recognize the vehicle with super-low
Chassis to perform the alignment test for this kind of vehicle and the vehicle with
enclosed housing. Aiming to the vehicle model, the system can automatically turn on the corresponding
functions of height measurement and counterweight, etc.
•The demonstration version can run all test flow, which makes user’s training more
Convenient and quick.
•Perform the special alignment test for Mercedes-Benz, BMW, Audi and Passat vehicles,
Etc.
•The units of the alignment parameters can be represented with Degree/Minute,
percentage degree, mm and Inch.
•The voice prompt function is provided during measurement, very easy to understand.
•Automatic check function for incorrect calibration is provided, which can prompt the
user to recalibrate in time.
•Client prompting function can make the client return visit in time.

3. The components of the wheel alignment
3.1 Overview
The wheel aligner consists essentially of the control panel, the measuring heads, the wheel clamps,
the steering wheel holder and the brake pedal pusher etc.
3.2 Operation panel
The control panel of the wheel aligner mainly consists of the housing (with recordings for the wheel clamps, main switch,
power line, power supply and charging cable), computer and Bluetooth data transfer.
Computer parts are in compartments in the housing. For printing the measurement results a printer is needed
preferably an inkjet printer (not included).
For a comfortable operation it is recommended to use the measuring heads # 1 and # 3 on the left side of the carrier and
Place the measuring heads # 2 and # 4 on the right side of the carrier.
Note: If the wheel aligner is not used, they should be placed correctly on both sides of the carrier and it should be
ensured that they are charged.
Do not place the control panel or probes in places with heavy spray or dust. Make sure the back of the control panel is well
ventilated and that the back of the computer is not blocked or the fan is stopped.
3.3 Computer system
The computer system of the wheel aligner consists of computer, monitor, keyboard and mouse.
The Windows operating system and the program of the wheel alignment device are preinstalled on the computer.
To ensure the safety of the system and for the best performance of the device should be on the computer system
never install other programs ore change some settings.
3.4 Printer (not included)
It is possible to set a printer. You can connect the printer directly to the computer ore connect it via wifi.
3.5 Bluetooth connector
The aligner is equipped with a Bluetooth communication device, as shown in the following figure.
Before use, insert the RS232 plug and USB port on the computer.

3.6 Wheel clamp
The wheel aligner has four wheel clamps. Turn the dial so that the distance is large enough to put the clamp on the rim
if necessary, insert the pins in reverse and / or into other insertion holes. Then attach the pins first to the rim flange and then to
the top of the rim flange. Turn the dial clockwise and tighten the wheel clamp. Make sure that the pins are even and clean.
After attaching, check tightness by pulling on the wheel clamp.
Note: applicable wheel sizes 10“-22“.

3.7 Steering holder
The wheel aligner has a steering wheel holder as shown in the following picture.
The steering wheel holder is used to fix the steering wheel against rotation during measuring operations.
3.8 Brake holder
The wheel aligner has a brake pedal pusher as shown in the picture below.
It is used to depress the brake pedal to prevent the vehicle from moving
of the measuring process rolls away.
3.9 Mechanical turntable (optional)

3.10 Measuring head
The wheel aligner is equipped with four measuring heads, which are mounted on the corresponding wheel clamps.
Before attaching the measuring heads, first attach the wheel clamps to the wheels, then insert the axle pin of the
corresponding measuring head into the hole of the central carr i e r .
After aligning the measuring head horizontally, tighten the adjustment knob on the wheel clamp.

4.2 Connect the device
•Connect the power cable.
•Push the ON button on the computer
•Push the ON button on the monitor
•Push the ON button on the printer
•The unit is correctly connect when all systems are working fine
4.3 Check the connection
• Drive a vehicle on the vehicle lift or over the pit so that the front wheels are centered on the turntables, apply the
handbrake. To protect the turntables from twisting, remove the pins on the turntables only after starting the vehicle.
• Attach the wheel clamp to the wheels and tighten with the knob. The pins of the wheel clamps should sit on the outer
or inner edge of the rim flange, depending on the rim type.
Make sure the height of each clamp is the same and avoid mounting on deformed areas.
• Install the measuring head on the correct wheel brackets according to the defined positions.
See the following picture:
•Adjust the measuring heads.
•Restart the computer and run the axis measurement program. On the main screen, press the [System] button (F5),
then press the [Sensor Information] button (F6).

5. Basic work steps with the wheel alignment device
The basic steps with the wheel aligner are the following:
Vehicle information procure → road test → Carry out testing prior test (each chassis part and tire wear carefully check) →
measuring and adjusting → test result print → back road test perform to confirm the results of the wheel alignment.
The order, the settings, the axle geometry for normal vehicles is:
Rear camber, track back, trailing forward, fall forward, front track.
The order of the axle geometry settings for multi-link axles (such as the VW Passat B5,AudiA4 /A6 /A8, etc.) is:
Rear camber → Rear track → Front camber → Front toe-in measurement → Front toe-in.
Ask the vehicle owner for drivability issues, as well as find out about past symptoms and wheel measurements, and brand,
model and year information.
Check each chassis part carefully, including dust sleeves, guides, handlebars, suspension ball joints, shock absorbers, tie rod
joint and steering mechanism in play and / or wear.
Then check the air pressure and compare if the tire wear is the same on both sides.
Do not perform the survey until the initial conditions are known.
If the measured values deviate from the given values, the wheel position must be corrected.
After completing the wheel alignment, check the vehicle to see if the deviating conditions have been eliminated.
If necessary, carry out the wheel measurement again.
5.1 Prepare for the measuring
1. driving a vehicle on the car lift or over the pit, so that the front wheels are on the center of the turntable, apply the hand
brake. To protect the turntables from twisting, remove the pins on the turntables only after starting the vehicle.
2. Attach the wheel clamps to the wheels and tighten with the knob. The pins of the wheel clamps should sit on the outer or
inner edge of the rim flange, depending on the rim type. Make sure the height of each clamp is the same and avoid
mounting on deformed areas.
3. Install the measuring heads on the correct wheel clamp according to the defined positions.
4. Adjust the measuring heads.
5. Mount the steering holder on the steering and fix this.
6. Mount the brake holder between the brake and the driver seat.
7. Start the alignment system with the power button.
