LAUNCH KWA-300 3D Wheel Aligner Operation Instructions

Rolling Run-out Compensation
Rolling run-out compensation is mainly used for getting
the inherent parameters of the targets before the normal
measurement, so as to ensure the measurement more
accurate. You do not always perform this operation. If
the measurement is accurate, the user can directly skip
this step, and start from Caster Swing measurement.
The interface is as shown in Fig.4.10:
Fig.4.10
Operating Procedures:
1.
Install four wheel clamp targets respectively;
2. Place the transition bridges at the appropriate
positions between the lift and the mechanical
turntables respectively;
3. Turn the front wheels straight ahead, and fasten the
steering wheel with steering wheel holder, and then
remove the brake wheel depressor. Move the
parking wooden chocks back by 30cm away to
ensure the vehicle can move freely within the
distance of 30cm;
4. According to the system operation prompts, please
push the vehicle back slowly until the system
prompts to pull the vehicle back to the original
location.
Caution:
1. It is strongly suggested to select this function
to ensure measuring accuracy;
2. Before performing Rolling run-out
compensation operation, be sure to fix the
steering wheel according to the requirements,
in order to avoid the wheels' swing to left or
right when performing Rolling run-out
compensation operation, causing the unstable
axis;
3. The line of sight of any camera cannot be
blocked during pulling and pushing vehicle;
4. Keep the force for pushing and pulling the
vehicle evenly, keep the measurement platform
level, and keep the vehicle moving smoothly;
5. Basically keep the target surface vertical to the
ground level, otherwise, too large elevation of
the target in motion will be resulted in, causing
the abnormal target image.
6. Please remove the transition bridges away from
the lift after finishing rolling run-out
compensation measurement.
[Red Target Status]
It indicates that the target image captured by camera
does not meet the measurement requirements (It is
usually because of the blocked light).
[Previous]
Return to the previous operation procedures.
[Run-out Compensation after Lifted]
Perform run-out compensation for the vehicle after it is
lifted up. The interface is as shown in Fig.4.11.
Fig.4.11
Operating Procedures:
According to the prompts on the screen, turn the target.
When it is turned by some angle value, the arrow head
on the interface will prompt the operator to turn the
target back. The interface is as shown in Fig.4.12.

Caster Swing
Kingpin measurement is aimed at the front wheels,
which includes kingpin inclination and caster. Correct
Kingpin Inclination can equalize the loads applied on
bearings so that the life of bearings can be prolonged
and the controllability of steering is improved. The
existence of kingpin inclination can make the
