1.3. laser saFeTY
GA60 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.

the main unit is designed to be wall mounted. select a suitable
position, ensuring that it is near to an electrical socket. using the back
plate as a template, mark the positions for four holes to be drilled. Drill
the holes to a suitable size and depth and using suitably strong fixings,
bolt the unit and back plate to the wall, two people will be needed to
manouvre the unit into place due to it's weight. Position the various
assemblies onto the main unit and plug the two leads into the two laser
alignment tools. Plug the unit into an electrical socket and switch on the
mains power switch. switch the two laser alignment tool switches to
position II and the recharging lights will illuminate. It is recommended
that the batteries are charged for at least 4 hours before using for the
first time.
note: the charging lights will illuminate even though the main unit is
switched off, they are there to show that the units are in charging mode.

ga60wK - optional wheel unit
to make GA60 fully portable, GA60WK fits to the base of the main unit.
to assemble, fit the four castor wheels to the underside of the tray,
securing with four bolts on each wheel unit. With the help of another
person, carefully tip the GA60 unit over and lay it on the floor. fit the
base to it, securing it with four screws. stand the unit back onto it's
wheels.

Prior to use, check that the tyre pressures are correct and if wheel covers are fitted, remove them. Ensure that the vehicle is on a smooth
level surface with the wheels pointing straight ahead, Do not back the vehicle into position, but drive straight ahead into position.
Ideally vehicle should be on a ramp or lift for easier access to the track rods, if adjustment is necessary.

FronT wheel alignMenT

Wheel alignment is the amount that the rear wheels is out of alignment to the front wheels. If the rear wheels are not aligned, the vehicle
may be steered from the rear, which will result in what is known as 'crabbing'. When a problem similar to the one shown in fig.1 occurs,
the vehicle will steer to the left, resulting in the steering wheel having to be turned to the right to counter-act the rear steering force. At the
same time the front wheel position adopts a set-back situation with respect to the vehicle's centre line. should the front wheels now be
measured from the front only, this set-back situation will not be noticed. so to offer a full alignment service a vehicle's trust angle must be
checked. Basically, rear wheel toe must be kept equal to the centre line and correctly toed in or out in order for the vehicle to handle
correctly.
