Measuring heads

The measuring heads are made up of CCD transducers to measure the horizontal angles and accelerometers
to measure the vertical angles. In the cable version, both the power supply and data transmission is via
cable. In the radio version, power is supplied by rechargeable batteries; when the batteries are fl at, meas-
urements can still be made by connecting the battery charge cables - supplied as option and not included in
the standard equipment - to the measuring heads. Data transmission is via radio.
To turn on the measuring heads, connect the power cables or, only for the radio models, press any key on
the keypad.

The measuring heads turn off automatically after about 15 minutes if no data is transmitted or
the cabinet is off.

3 - PREPARING FOR MEASUREMENT

3.1 - Home page

The home page appears at the beginning of each alignment procedure.
From this page you can select the car and truck alignment procedure, as well as the measuring mode with 2
or 4 measuring heads. You can also access the Settings or the Customer Databank pages.
The measuring mode with 2 measuring heads allows measuring and adjusting only the toe-in and camber of
the front axle. The measuring mode with 4 measuring heads is faster because you do not have to fi t the rear
measuring heads.

It is recommended that only experts use the mode with 2 measuring heads as it is not guaranteed
that the steering wheel stays straight.

Generally, when the home page is displayed, the preliminary operations on the vehicle are performed.

To prepare for measurement:

Position the vehicle on the turn plates1.
Mount the wheel clamp and the measuring heads on the vehicle wheels2.
Turn on the computer3.
Turn on the measuring heads4.

5 - VEHICLE SPECIFICATIONS

The Vehicle Specifi cations page allows analysing the manufacturer's specifi cations to decide which opera-
tions are to be performed.
In most cases the manufacturer specifi es the minimum, standard and maximum values for the main angles:
toe-in, camber and caster.

Nevertheless, in some cases the manufacturer might:

Require to position loads in the vehicle or fi ll the tank before making the measurement and adjustment•
Specify angles normally ignored: SAI, TOOT or maximum steerings•
Specify the maximum values for the difference between the right and left wheel camber or caster•
(car only) Prescribe a special adjustment method, as the 'Toe-in curve'•
Give different specifi cations based on the measurements of the ride height or the inclinations of parts of •
the suspension.
Check some vehicle measurements (e.g. ride height or component tightening torque) or apply special •

tools (e.g. toe-in bar) before making the measurement and adjustment
On the Vehicle Specifi cations page you can see which of these things are required and decide whether or
not to perform these operations.
You can also set the rim diameter in order to correctly display the toe-in in millimetres or inches and custo­mise the vehicle specifi cations.

If you do not set the correct rim diameter when the toe-in is displayed in millimetres
or inches, the measurement may differ from what is obtained when measuring the
toe-in with a rule. Nevertheless, the rim diameter does not need to be set correctly in
order to correctly adjust the vehicle; it is suffi cient to position the indicator in the green
zone during adjustment.

this is not the case, act on the vehicle adjustments to bring the measurements within tolerance.

If they indicate that you need to enter the measurement made, select the row from the corresponding •

table. The vehicle specifi cations are modifi ed as a result.

You are advised to follow the manufacturer's indications; if it is required to set the
measurement and this is not done, average values are used for the specifi cations.

The Vehicle Customisation page allows adding vehicles to the vehicle database.
To do this, fi rst select a vehicle on the Vehicle Selection page and then access this page to modify the
model and the specifi cations. Of course, starting from a vehicle with similar specifi cations to the one to be
added will simplify the job.
On this page you cannot change the vehicle manufacturer, which must therefore be selected fi rst. You
cannot add vehicles whose manufacturer is not already in the list of manufacturers on the Vehicle Selection
page. There is however a generic manufacturer name called 'Extra' at the end of the list where these vehi­cles can be added. You cannot add ride height data nor adjustment help images.

5.5 - (truck only) Axle confi guration

The Axle Confi guration page allows confi guring the axles of trucks, buses or semi-trailers

You can confi gure up to 7 axles of which 2 front ones as steering axles and 5 rear axles; the last rear axles can
be confi gured as steering axles. On this page, select the reference axle, i.e. the rear axle used to establish,
together with the fi rst front axle, the direction of the truck symmetry axis. The reference axle is highlighted
by the black vertical arrow in the middle of the axle; the fi rst time you confi gure, place the rear measuring
heads on it.
To select the reference axle, follow these criteria in order of priority:

Axle 1. with possibility to adjust the thrust angle. In the case of a semi-trailer, if it is not possible to adjust
the thrust angle for any axle, select the one where the tyres are less worn, as they will be better alig­ned with the fi fth wheel pin compared to the other axles

Non-steering axle to prevent movement during the procedure2.
Axle as far as possible to the rear3.

Axle with possibility to adjust the distance between the wheels and the chassis 4.
The software automatically sets the last rear non-steering axle as reference axle, since this is the most
common case. To set a different axle, confi gure as steering axles the ones you do not want to use as reference
axle. The only purpose of confi guring the axles as steering and non-steering is to select the reference axle
and it has no effect on the alignment procedure.

heads on the fi fth wheel pin adaptor.

Turn the adaptor as indicated until the word appears.

6 - RUNOUT

The runout phase allows correcting the wheel clamp mounting error.
This error is caused by imprecise positioning of the claws or by deformation of the rim or the wheel clamp
and is diffi cult to avoid. Even though there are wheel clamps on the market that are claimed to be "without
runout", there is actually no certainty that they suffi ciently reduce the error.

It is advisable to always execute runout.

The runout phase consists of executing various measurements at various wheel rotation angles.
A comparison of these values allows the software to correct the wheel clamp mounting error.
There are four runout methods: in two of these the wheels are turned by pushing the vehicle on the
ground, and in the other two by lifting the vehicle and turning the wheels by hand.
Each method is suitable for a certain condition; there is no best method for any one condition.

Fast If the conditions to execute this method are given, it is the

preferable one to use as it is fast and accurate. Since the vehicle
is moved on the ground, the suspension settlement is not altered
with respect to driving on the road and hence the measurements
are more realistic than the methods where the vehicle is lifted.
This method requires a fl at ground surface without steps (for
example, on sides of turn plates), little steering play and posi­tioning of the steering lock to prevent the wheels from steering
when the vehicle moves (the instrument will signal an error if
this occurs). The surface must also be suffi ciently long to allow
the wheels to turn 180° and the vehicle must be light enough to
be easily moved.

Fast

fast as on the ground

fast as on the ground

Like the 180° runout on the ground, this method is fast and does not
alter the suspension
The requirements are identical, except that this method can also be
used with shorter surfaces (car lifts) as the vehicle needs to be pushed
only 90° to turn the wheels. An argument against this method is that
it is slightly less accurate than the 180° method and you are more
frequently asked to level the measuring heads because of the tighter
tolerance. It would be a second choice instead of the 180° runout on
the ground in case of short car lifts. It also requires that the ground or
lift be level.

If the conditions for the methods on the ground are not given,
the methods with the vehicle lifted must be used, among
which this one is preferable as it is slightly faster and more
accurate than the 3x90° method. It is as accurate as the 180°
runout on the ground but is slower because the vehicle must
be lifted and the wheels turned manually one at a time.
Since the vehicle is lifted the suspension settlement is altered
with respect to driving on the road and hence the measu­rements are slightly less realistic than the methods on the
ground. Some car makers specify that the methods with the
vehicle lifted must not be used. To reduce this effect, the
suspension must be settled after lowering the vehicle.

Unlike the other three methods, it allows executing the
runout of one wheel without having fi tted the measuring
heads on the others.
This may come in handy because you can execute the runout
immediately after fi tting one measuring head without fi rst
having to fi t the others. It is obligatory to use this method
when the alignment sensors have been darkened by parts of
the lift or when using the mode with 2 measuring heads.

7 - STEERING

The steering function allows measuring the characteristic steering angles: caster, SAI, TOOT.
It consists of making several measurements with the wheels steered at different steering angles.
You can select from three steering modes:

FAST steering: recommended because it is fast to execute•
10° steering: there is no technical reasons to use this method but it is available because many operators •
are accostumed to use it. It is advisable to execute fast steering instead as it is faster
20° steering: necessary to measure the TOOT and when imposed by the vehicle manufacturer•

Press the key corresponding to the desired steering mode.

During adjustment the wheel angles are continuously measured and displayed so that the effect of the
adjustments can immediately be seen.
The main angles are shown both in value

and in graphic form by an indicator on a green and red scale

Adjust the angles until the indicator is in the green zone representing the angles in tolerance, while the red
zone represents the angles out of tolerance.

Front axle adjustment1.

Normal car adjustment procedure•

Rear axle adjustment1.
Front axle adjustment2.

VAS car adjustment procedure for vehicles equipped with Multilink suspension•

Front axle adjustment4.

Truck adjustment procedure•

Rear reference axle adjustment1.
First front axle adjustment2.
Adjustment proceeding towards the rear of the intermediate axles3.
If necessary, adjustment of the last rear steering axle (only if present)4.
If necessary, adjustment of the parallelism between the two front steering axles (only if present)5.

Semi-trailer adjustment procedure•

Adjusting the rear reference axle 1.
Adjusting the other rear axles2.
Adjusting the last rear steering axle (only if present)3.

The software guides you through the adjustment procedure, one by one showing the phases to carry out.
The possible phases are described in the following chapters.

9.2 - (car) Adjusting a rear axle

The Rear Adjustment page displays the measurements and relative tolerances of the camber and partial
toe-in of both wheels. It displays also the thrust angle and, in small font, the total toe-in, the difference
between the left and right camber and its maximum permitted value.

I 0645 37GB

Adjust in order the wheel camber and toe-in until the indicator is in the green zone. The thrust angle is
cancelled when the toe-in of the wheels is the same.

For optimal adjustment, fi rst adjust the camber and then the toe-in

If it is diffi cult to access the adjustment points, you can use the "freezing" procedure to adjust with the
vehicle lifted.

To make it easier to identify the adjustment points, use the adjustment help images.

Freezing see chapter 9.7
Displays the adjustment help images see chapter 5.1

Changes the display from partial toe-in to total toe-in or shows the front and rear axle

simultaneously see chapter 9.3

9.3 - Adjusting a front axle

Before adjustment of a front axle the following may appear:

Level the steering wheel and position the steering lock1.

Press 2. or wait a few seconds for the Front Adjustment page to appear

Correctly level the steering wheel and fi rmly position the steering lock; this is required
to prevent the steering wheel from going askew.

The Front Adjustment page displays the measurements and the relative tolerances of the caster, camber and
partial toe-in of both wheels in large font. As alternative to the partial toe-in angles you can view the total
toe-in and the steering angle.

I 0645 39GB

The differences between the right and left camber and caster and the relative tolerances are also displayed
in small font, as are the partial and total toe-in if not already displayed in large font.
The display of the partial toe-in allows adjusting the toe-in of vehicles equipped with a suspension system
that allows adjusting the two wheels independently; this is true for most cars. Vice versa, the display of the
total toe-in and the steering angle allows adjusting vehicles equipped with a total toe-in adjustment bar,
which does not allow adjusting the two wheels independently; this is true for all trucks and some off-road
vehicles.
Displaying the 2 axles simultaneously allows you to adjust the 2 vehicle axles at the same time from one page,
thus checking the trend of the angles during adjustment.

Adjust in order the caster, camber and toe-in of the wheels until the indicator is in the green zone

For optimal adjustment follow the adjustment order: caster, camber, toe-in.

From the Front Adjustment page you can go to the Steering page.
In the case of the truck procedure, if you wish to execute steering, you need to access it from this page.
In the case of the car procedure, it is advisable to repeat steering as a check if the caster is adjusted, since
the caster measurement displayed on this page is necessarily an estimate.

Adjustment sequence for the truck procedure:

Centre the steering box by turning the steering wheel1.
If nec2. essary, straighten the steering wheel by acting on the adjuster between the steering box and the steering

wheel without moving the steering box
Lock the steering wheel with the steering lock3.
Adjust underneath the vehicle to bring the total toe-in into tolerance and the steering angle to null 4.

If it is diffi cult to access the adjustment points, for example, because the vehicle is on the ground or the
adjustment point is hidden by parts of the suspension, you can use the "freezing" procedure to adjust with
the vehicle lifted or the wheels steered.

To make it easier to identify the adjustment points, use the adjustment help images.

: Freezing see paragraph 9.7
: Displays the adjustment help images see paragraph 5.1

: Switches the display from partial toe-in to total toe-in or shows the front and rear axle

simultaneously

GB

9.4 - (truck) Adjusting a rear axle

Before the Rear Adjustment page, the Chassis Distance page appears to remind you to adjust the axle with
respect to the chassis.

Check with a rule and if necessary adjust the distance between the wheels and the chassis so that it is 1.
the same for the right and left wheels

Press 2. or wait a few seconds for the Rear Adjustment page to appear

Even if the distance between the wheels and the chassis is not adjusted, the wheels will be aligned with
each other at the end of the alignment procedure. Nonetheless, if the distances between the wheels and
the chassis differ greatly for the reference axle, at the end of the procedure the wheels might not be alig­ned with respect to the chassis and the truck will thus move in "dog step" with the consequent aerodynamic
problem.

It is advisable to adjust the distance between the wheels and the chassis at least for the rear

reference axle.

The Rear Adjustment page is similar to that described in paragraph 9.2.

The meaning of the value displayed in the box depends on the axle being adjusted

Reference axle: Thrust angle (angle between the axle direction and the truck symmetry)•
Other rear non-steering axles: Scrub angle (angle between the axle direction and the thrust line).•
Rear steering axles: Disabled•

I 0645 41GB

9.5 - (truck) Adjust the parallelism between the two front steering axles

In the case of trucks equipped with two front steering axles, at the end of the adjustment procedure you
are asked to position the four measuring heads on the two front steering axles to adjust the parallelism
between the direction of the fi rst and the second front steering axle.

Adjust the parallelism of the two steering axles taking care not to excessively steer the wheels; in this case
a warning will be displayed.

I 0645 42

GB

9.6 - (car, VAS procedure) Adjusting the front toe-in with the vehicle resting on

a support (toe-in curve)

For vehicles for which the VAS procedure is required, when exiting the Rear Adjustment page, a message is
displayed asking you to do some checks on the vehicle.

Check the vehicle conditions1.

If they do not fall within one of the cases contemplated in the message, press to go directly to
the Front Adjustment page

otherwise press to continue. The following appears:

Lift the vehicle and position the VAS tool underneath the front axle2.
Move the adapters into "raised" position and position the vehicle on them lowering it slowly3.

I 0645 43GB

Press 4. . The following appears:

Adjust the toe-in by acting on the upper head5.

Press 6. and the following appears:

Lift the vehicle, remove the VAS tool, lower the vehicle and settle the suspension7.

Press 8. to go to the Front Adjustment page

9.7 - Adjusting with the wheels raised or steered (freezing)

If it is diffi cult to access the adjustment points, for example, because the vehicle is on the ground or the
adjustment point is hidden by parts of the suspension, you can use the "freezing" procedure to adjust with
the vehicle lifted or the wheels steered.

Freezing is particularly useful in the case of a 2-column car lift

The Freezing procedure consists of storing ("freezing") the measurements with the vehicle lowered and the
wheels straight in order to keep them unaltered also after the vehicle has been lifted or the wheels stee­red. Thus you can adjust the angles to within the specifi ed tolerances as if the vehicle were still lowered
with the wheels straight.
This procedure can be activated on both the Front Adjustment and the Rear Adjustment page.

Starting from an adjustment page:

Press 1. to freeze the measurements. The graphics shows that the measurements have
been frozen

I 0645 44

GB

Lift the vehicle or steer the wheels2.

Press 3. to unfreeze the measurements

Adjust the angles4.

If you are on the Rear Adjustment page and wish to do so, press 5. to go to the Front Adjustment page
and adjust the front angles.

Press 6. to again freeze the measurements

Lower the vehicle or straighten the wheels7.

Press 8. to again unfreeze the measurements

If you go from the Rear Adjustment page to the Front Adjustment page with the vehicle lifted, for easier ope­ration it is suggested to level the steering wheel and position the steering lock before lifting the vehicle.

9.8 - Adjustment in case of interruption of the infrared rays

If you are unable to adjust without standing between the optical sensors, and the warning that the rays are
interrupted appears, you can disable the message in order to adjust the camber.

15 - STORING AND SCRAPPING

15.1 - Storing

In the event of long-term storage, disconnect the power supply and protect any parts which may be dama­ged by excessive accumulation of dust, such as the printer and the display. Grease parts which may be
damaged if allowed to dry out.

15.2 - Scrapping

If the machine is no longer to be used, it must be made inoperational. Render harmless any parts which
may constitute a source of danger. Assess the machine classifi cation according to the degree of disposal.
Take scrap metal to specifi c waste collection centres. If deemed special waste, dismantle and separate
into homogeneous groups and dispose of in accordance with the laws in force.

16 - TESTING THE MEASURING HEADS BY FITTING THEM ON THE VEHICLE

THIS TEST REQUIRES EXTREME ACCURACY. FIRMLY SECURE THE CLAMPS ON THE WHEELS, FIT THE MEASURING HEADS AND
SECURELY TIGHTEN THE CLOSING KNOB. NEVER MOVE THE VEHICLE.

16. 1 - Measurement I – Toe-in and camber in driving direction

Position the vehicle in the measuring position but not above the turn plates and the sliding plates. Engage the
brake pedal lock. Fasten the quick-fastening units. Fit the measuring heads and align them horizontally using
a spirit level. Measure the total toe-in on the front and rear wheels based on the measurement sheet (rows
1-2) and note down the values in column 1. Measure the camber on the front and rear wheels based on the
measurement sheet (rows 3-6) and note down the values in column 1.

16.2 - Measurement II - Toe-in and camber in reverse driving direction

Exchange the front left measuring head with the rear right measuring head, and the front right measuring
head with the rear left measuring head, then horizontally align all the measuring heads using a spirit level
taking care not to move the vehicle. Measure the total toe-in on the front and rear wheels based on the mea­surement sheet (rows 1-2) and note down the values in column 2. Measure the camber on the front and rear
wheels based on the measurement sheet (rows 3-6) and note down the values in column 2.

16.3 - Evaluation of the values measured during the measuring head test

Column Row Operation

If there are different signs in the same row, subtract the smaller from the

1 and 2 1-2

3-6

Values to compare:

3 1 with 2

3 with 6
4 with 5

4

3

larger value and note down the result in column 3. Note down the larger
value sign in column 3

If the signs are the same, add the measurement values and note down the
result with the sign in column 3

If there are different signs in the same row, add the values and note down
the results in column 3. Note down the sign of column 1 in column 3.

If the signs are the same, subtract the smaller from the larger value and
note down the result in column 3. If the larger value is in column 1, the
sign is accepted; if the larger value is in column 2, the sign is changed

If the signs are different, add the measurement values and note down the
result in column 4

If the signs are the same, subtract the smaller from the larger value and
note down the result in column 4

If the signs are different, subtract the smaller from the larger value and
note down the result in column 4

If the signs are the same, add the measurement values and note down the
results in column 4

The values in column 4 must be smaller than 3'. If they are larger, it means
that errors occurred during the measurement (e.g. the vehicle or the
quick-fastening units moved) and the measurement must be repeated

The values in column 3 must be smaller than 6'. If the differences are
greater, the device must be recalibrated (Technical Service)
