Operations
Hanging wheel camber:
Adjustment of the camber with the vehicle lifted available for front or rear axle.
Procedure in two steps.
1 - Normal camber measurement.
Reference values are memorized.
2 - Vehicle on lift: values displayed are benchmark values
and can be used as a starting point for your adjustments.
Hanging wheel castor:
Adjustment of the castor with the vehicle lifted.
Same procedure as camber in 2 steps.
Brake pedal press is absolutely necessary.
Confirm your adjustment by a new steering test to memorize the new values.
Alignment variance:
A measurement of the difference between two alignments from a low position (B) and a high position
(H) of the car.
This procedure is available for front and rear axle.
Rim run-out compensation:
Automatic correction of rim runout and the head carrier.
.
Two procedures are available on the GTR.600 depending on the lift type.
A - Longitudinal
Measurement in two half-turns the wheel by the camber and the back IR sensors.
B - Transverse
Measurement in two half-turns the wheel by the camber and the front IR sensors.
6 - Basic Principles
The GTR.600C and GTR.650C have been designed by FACOM in order to ensure that all operational,
inspection and adjustment procedures are entirely visual and readily visible at distances of up to six metres
thanks to the colour screen included.
On-screen representation of vehicle wheels corresponds to reality (for example, if the vehicle requires
negative camber, the wheels when adjusted are shown with negative camber). The operator is informed on
the various phases of the operation by graphics and colour codes.
Selection of icons and confirmation of commands are based respectively on the direction and validation
keys on the keyboard, the remote control or use of function keys F2 to F9 on the keyboard. In all system
screens the menu bar offers the choices available at each stage in the current operation.
