• Yellow LED switched on - recharge under
way;
• Red LED switched on - recharge problems;
• both LEDs switched off and head function-
ing - battery charged up;
• both LEDs switched off and head not func-
tioning - battery faulty or absent

RUNDOWN PROCESS

In order to work well and last a long time, the
NiMH type batteries (used in the measuring
sensors of the wheel aligner) need to be periodi-
cally run down.
The rundown process involves running the four
batteries down completely at a constant current,
then recharging them.
You are advised to carry out the rundown process
every 15/30 days, depending on the cycle of re-
charges carried out (the more often the recharge,
the more often the rundown procedure must be
carried out). The rundown is effected by leaving
the heads switched on, on the head test page,
until they are completely run down.
Note:
• The batteries are NiMh, 2600 mA/h, 7.2V. New
batteries, fully charged, guarantee 8 hours of
continuous working.

IMPROPER USE

The Personal Computer installed in the central
unit should only be used with the programs
supplied by CORGHI S.p.A.
ATTENTION
You are strongly advised not to use the Personal
Computer for games or with other software
based on unauthorised copies, to avoid reduc-
ing the safety of plants and persons. This is
mandatory to avoid any possible contamination
from viruses.
In any case, you are advised to check the com-
patibility of all original software not supplied by
CORGHI S.p.A. with the Corghi Technical Service.
ATTENTION
Do not remove the Personal Computer from
its installation position to avoid any damage
to the connections.

MOST COMMONLY
ENCOUNTERED
VEHICLE ALIGNMENT
FAULTS
Vehicle tends to wander to the left or the right.
Cause: tyre side slip.
Invert the position of the wheels on the same axle:
if the vehicle now tends to wander to the other
side, take one of the wheels whose position you
have already inverted and turn the tyre on the rim;
if the wander direction does not change per-
form the same operation on the wheels of the
other axle;
if this double inversion procedure fails to solve
the problem, check that camber values on the
same axle are identical, make the same compari-
son for caster values.
Steering wheel not aligned with vehicle tra-
jectory.
Possible causes:
- mechanical backlash;
- Compensation has been skipped or performed
incorrectly;
- wheel alignment performed using two sensor
procedure;
- wheel alignment performed with the steering
wheel off centre;
- front wheels adjusted with respect to the axis
of symmetry.
Disparity between steering locks.
The steering box range must be centred by
counting the number of steering wheel revolu-
tions from full lock to full lock.
Position the steering wheel in the centre of its
range, clamp the steering wheel and perform
the normal procedure for adjustment of the front
half toe values.
Position the steering wheels correctly, disas-
sembling it from the steering column if needs be.
Steering wheel is excessively stiff with vehicle
stopped.
Possible causes:
- excessive caster;
- incorrect king pin angle;
- excessive camber.
Steering wheel return is too forceful or insuf-
ficient when driving.
