Definition
KWA-300 3D Wheel Aligner is a precision measurement instrument designed to measure the wheel alignment parameters and compare them with the specifications provided by vehicle manufacturer. It also gives instructions to the user for performing corresponding adjustments so as to get the best steering performance and reduce tire wear.

When Is Required Wheel Alignment
- The driver must firmly hold the steering wheel to maintain a straight-ahead driving.
- Abnormal wear of tires occurred, such as single side wear, concave-convexity wear and featheriness wear.
- Too heavy or too light steering, or shaking at high-speed driving.
- When the tire(s), steering joint or shock absorber are replaced.
- When the vehicle is impacted.
- When the vehicle has driven for the first 3000km or 10000km.

Main Vehicle Alignment Parameter
The wheel alignment mainly consists of camber, caster, toe-in, kingpin inclination, toe-out on turns, wheelbase difference, tread difference, etc. They are designed mainly to improve the steering performance and driving stability of the vehicle, and reduce tire wear.

Toe-in and Toe-out
The toe setting is the amount by which the front or rear wheels point inwards or outwards at the front of the wheel in relation to each other (see Fig.1.1).
The toe setting is the amount by which the front or rear wheels point inwards or outwards at the front of the wheel in relation to each other (see Fig.1.1).
Fig.1.1
When the wheels point inwards they are said to toe-in. Toe-in figures are given a positive value.
Conversely when the wheels point outwards they are said to be toe-out and the figures are shown as a negative value.
Conversely when the wheels point outwards they are said to be toe-out and the figures are shown as a negative value.
The purpose of correct toe is to ensure that the wheels run parallel when the vehicle is driving. An incorrect toe setting may affect the stability and controllability of the vehicle.
Camber
Camber is the leaning of the KWA-300 Wheel Aligner inwards or outwards from the vertical.
If the road wheel leans outwards from the vertical, it is said to have positive camber and when leaning inwards from the vertical – negative camber, looking from the front or rear of the vehicle. See Fig.1.2.

Camber is measured in degrees.
