CALIBRATION PROCEDURE
Mount and level the Calibration Bar on Calibration Stands or the rear of the Storage Cart
Calibration of Front Wheel Toe Laser Beam (See Figure 42)
1) Rotate the tapered magnets on the Left and Right
Toe Gauges to zero.
2) Mount the Left and Right Toe Gauges on the
ends of the Calibration Bar. Be sure the centers of
the magnets fit over the raised machined surfaces
at the ends of the Calibration bar.
3) Level both Toe Gauges and check the laser beam on the mirror screen (A). If the laser beam image
is not located midway up on the mirror screen (A), loosen the knob (E) on the Left Toe Gauge and
slide it up or down. This moves the laser beam image vertically until it is on the mirror.
4) The center of the laser beam image should be on zero on the screen (A). If not, alternately adjust
Allen set screws of the laser diode bulb retainer on the Left Toe Gauge until the center of the
beam image reads zero on the Right Toe Gauge screen (A).
There are four Allen set screws on the laser diode retainer. The top and bottom set screws (D)
control the vertical movement of the beam image. The left and right screws (B) control side-to-
side movement of the beam image.
5) Adjust the mirror (A) up or down as required so the reflected laser beam image is on the front toe
scale. Loosen knobs (R) to make any required adjustments.
6) Adjust Allen set screws (F) until the center of the laser beam image reads zero on the front toe
scale (C).
