1.2 LASER SAFETY
The GA70CR Calibration rig is used is used in
conjunction with units from the GA70 which utilise
a Class II laser that emits low levels of visible
radiation (i.e. wavelengths between 400 and 700
nanometres which are safe for the skin but not
inherently safe for the eyes. The Class II emission limit is set
at the maximum level for which eye protection is normally
afforded by natural aversion responses to bright light.
Accidental eye exposure is therefore normally safe, although
the natural aversion response can be overridden by
deliberately staring into the beam, and can also be influenced
by the use of alcohol or drugs.
WARNING! Do not look or stare into the laser beam as
permanent eye damage could result.
DO NOT direct the laser beam at any person’s (or animal’s)
eyes as eye damage could result. If the beam is
obstructed by a person during use, release the contact
switch immediately.
DO NOT use the equipment while under the influence of
alcohol, drugs or whilst on medication.
Be aware that reflections of the laser beam from mirrors
or other shiny surfaces can be as hazardous as direct eye
exposure.
2. INTRODUCTION
Used to check and adjust the alignment of the lasers on the GA70
Four-Wheel Laser Aligner. This unit will allow workshops to check
and adjust in-house. Laser heads secure to the rig and rest on the
bobbins that contact the vehicle’s wheel rim. Supplied with
comprehensive instructions.
fig.1

3. RIG OPERATION
4.1.9 Rear lasers should align with the calibration line on the rear
flags.
4.1.10If front or rear Lasers are not aligned the units need to be
recalibrated.
4.2 Calibration
4.2.1 Remove the protective laser calibration guard on the laser
that needs to be adjusted.
4.2.2 Slacken the two allen nuts on the laser that needs adjusting.
See figs. 3 & 4.
4.2.3 Turn on the laser.
4.2.4 Adjust laser to the correct position by moving the slotted fixing
up or down the slot as required. When the laser light strikes the
zero toe mark or the calibration line on the rear flags tighten
the two allen nuts and replace the protective covers
4.2.5 Check ALL lasers are aligned correctly.
4.3 GA70CR – Calibration Rig yearly/periodic inspection
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.
4.4 GA70CAL
4.3.1 We also offer a calibration service at SEALEY where we will
check/calibrate the customers GA70 unit.

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.
