4.3.1 Mearsure/check the distance between the two front and two
rear calibration contact points to make sure the measurement
are the same.
4.3.2 rear flags - Measure distance from the frame and the vertical
calibration lines. Both measurement must be the same.

4.1 GA70 Calibration Check
4.1.1 Visually inspect the laser units to make sure they are not
damaged or bent. A damaged Laser Head may not calibrate
correctly.
4.1.2 remove the 6 nuts from the threaded ends of the 6 mounting
pillars (1 at the top and two at the bottom on each side) see
fig.1-1.
4.1.3 Adjust the height of each laser unit to match the mounting
pillars using the black knob on each unit. see fig.2-B. Move
the three wheel rim locators to the outside end of their
respective slots.
4.1.4 fit the two laser alignment units onto the pillars and secure
them hand tight using the nuts previously removed. see fig.2.
4.1.5 on each side of the rig adjust the position of the three wheel
rim locators onto the rig alignment pads (see fig.2 InsEt 'A')
4.1.6 Make any necessary fine adjustments then turn on the Lasers.
Manoeuvre one of the laser Heads backwards/forwards so the
Lasers read as near to Zero as possible.
4.1.7 tighten the 6 holding nuts.
4.1.8 front Lasers should read Zero using the correct calculation.
observe where the laser line falls on each toe scale. Either
both lasers will be pointing to Zero which is correct, or, one
laser will read in the rED and one laser will read in the
GrEEn. In this case subtract one from the other and the
reading should be Zero. for example, 1 rED minus 1 Green
equals ZEro (calibration is correct). If the reading is not Zero,
calibration is required.
