WARNING!
Do not switch on the laser unit when detached from the main gauge. When correctly assembled to the gauge the laser
should only be switched on when the two sides of the gauge are correctly positioned in relation to each other either for calibration
purposes or for wheel alignment use.
3.1 ASSEMBLY - fig 1
3.1.1 Slide the four arms onto the main bars, two arms onto each bar, two of the arms have two thumb screws, these must go on first and
are labelled 'M' - mirror and 'L' - Laser and so should be put on the correct bars.
3.1.2 Tighten the thumb screws into position.
3.1.3 Use the thumb screws on the base to adjust the level, using the built in spirit level as guidance.
3.1.4 Remove the battery end cap screw then cap (fig.1) to reveal the battery compartment. Remove the small screw securing the top of the
compartment and insert two AA batteries.
3.2 CALIBRATION.
The gauge will be calibrated each time it is used as part of the process of checking wheel alignment. Calibration will be
done with the two halves of the gauge facing each other with the contact bars touching. For further details refer to the operating
instructions which follow.

1.1 GENERAL SAFETY
WARNING!
Ensure Health & Safety, local authority, and general workshop practice regulations are adhered to when using this equipment.
Maintain the
gauge in good condition (use an authorised service agent).
Replace or repair damaged parts.
Use genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
Locate gauge in a suitable working area, keep area clean and tidy and free from unrelated materials.
WARNING!
Use gauge on level and solid ground.
Keep the gauge clean to ensure accurate performance.
DO NOT
use outside in damp or wet weather conditions.
DO NOT
allow untrained persons to operate the gauge.
DO NOT
leave the gauge unattended.
WARNING!
When setting front end alignment on commercial vehicles never make adjustments to drop arms or interconnecting links.
Doing so could result in serious tyre, wheel and steering problems.
Any alignment changes deemed necessary as a result of using this equipment must be made strictly in accordance with the vehicle
manufacturer’s recommendations.

1.2 LASER SAFETY
GA48.V2 utilises 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.
