INTRODUCTION
The purpose of this manual is to provide the owner and operator with effective and safe
instructions for the use and maintenance of the wheel balancer.
Follow all of the instructions carefully and your machine will assist you in your work and
give long-lasting and efficient service, in keeping with manufacturer traditions.
The following paragraphs define the levels of danger regarding the machine, associated
with the warning captions found in this manual.
DANGER
Refers to immediate danger with the risk of serious injury or death.
CAUTION
Dangers or unsafe procedures that can cause serious injury or death.
WARNING
Dangers or unsafe procedures that can cause minor injuries or damage to property.
Read these instructions carefully before starting the machine. Keep this manual and all
illustrative material supplied with the machine in a folder near it where it is readily ac-
cessible for consultation by the operators.
The technical documentation supplied is considered an integral part of the machine; in
the event of sale all relative documentation must remain with the machine.
The manual is only to be considered valid for the machine model and serial number
indicated on the data plate.
CAUTION
Adhere to the contents of this manual: The producer declines all liability in the case
of actions not specifically described and authorised in this manual.
NOTE
Someof theillustrations containedin thismanual werederived fromphotos ofprototypes:
the standard production machines may differ in some details.
These instructions are for the attention of personnel with basic mechanical skills. We have
therefore condensed the descriptions of each operation by omitting detailed instructions
regarding, for example, how to loosen or tighten the fixing devices on the machine. Do not
attempt to perform operations unless properly qualified and with suitable experience.
If in need of assistance, call an authorised assistance centre.

TRANSPORT, STORAGE AND HANDLING
Handling and manoeuvring before installation
The basic wheel balancer packaging consists of 1 wooden crate containing:
- the wheel balancer (Fig.7)
- equipment;
- the wheel guard and corresponding mounting tube (C, Fig.4a - D, Fig. 4a).
Before installation, the wheel balancer must be shipped in its original packaging, making
sure that the machine is maintained in the position indicated on the outer packaging. The
machine can be moved by placing the packaging on a wheeled trolley or inserting the
forks of a fork lift truck in the relative slots in the pallet (Fig. 1).

- The machine must be stored in an environment meeting the following requirements:
• relativehumidityrangingfrom20%to95%;
• temperaturerangingfrom-10°to+60°C.
WARNING
Do not stack more than two packs to avoid damaging them.
After installation, the machine can be moved using the following methods:
- with a crane, using special equipment that holds the machine at the designated lifting
points (Fig. 2);

UK
- by inserting the forks of a lift truck under the machine so that the centre of the forks
correspond approximately to the centre line of the body (Fig. 3).

CAUTION
Always unplug the power supply cable from the socket before moving the machine.
CAUTION
Never apply force to the wheel spin shaft when moving the machine.
INSTALLATION
CAUTION
Take the utmost care when unpacking, assembling, lifting and setting up the machine
as indicated below.
Failure to observe these instructions can damage the machine and compromise the
operator's safety.
Removetheoriginalpackagingmaterialsafterpositioningthemasindicated onthepackaging
and keep them intact so the machine can be safely shipped at a later date if necessary.
CAUTION
Choose the place of installation in compliance with local regulations on occupational
safety.
In particular, the machine must only be installed and used in protected environments
where there is no risk of anything dripping onto it.
76 EM 9250 Operator’s manual
IMPORTANT: for the correct and safe operation of the machine, the lighting level in the
place of use should be at least 300 lux.
The floor must be strong enough to support a load equal to the weight of the equipment
plus the maximum load allowed. The support base on the floor and the envisaged fixing
means must also be taken into account.
Environmental operating conditions must comply with the following requirements:
-relativehumidityrangingfrom30%to80%(withoutcondensation);
-temperaturerangingfrom0°to+50°C.
WARNING
For information concerning the technical features, warnings and maintenance instruc-
tions consult the related operator manuals provided with the documentation of the
machine.
CAUTION
The machine must not be operated in potentially explosive atmospheres.
The machine is supplied partially disassembled and is to be assembled according to
the procedures described below.
Installing the wheel guard with the corresponding mounting (Fig. 4)
- Install the bush (A, fig. 4) on the pivot (B, fig. 4). While doing this, ensure that the groove
on the pivot is aligned with the pin in the bush.
- Fasten the tube on the pivot using the M12 screw supplied.
- Insert the metal tube (D, Fig. 4a) into the two plastic guard front holes (C, Fig. 4a).
- Couple the guard to the rear side of the tube by inserting it into the correct position
with snap-in coupling (E, Fig. 4a).
- Secure the wheel guard by tightening the screw provided (F, Fig. 4a).

Fixing the machine to the
ground (Fig. 6)
The machine is to be fixed to the ground if:
- Itdoesnothavetheaccessorytriangularfoot.
- If it does have the accessory triangular foot
but is going to be used with wheels heavier
than 50Kg. In such a case the triangular foot
will have to be removed in order to fix the
front bracket.
- Undo the three M8x60 hex head screws
fastening the machine to the pallet.
- Remove the plastic washers between the
casingandthethreeLbrackets:these brack-
ets will be used to fasten the machine
to the floor.
- Refit the brackets on the machine in the
original positions, without tightening
the screws.
- Positionthemachineonthegroundinthe

surrounding spaces correspond to the
minimum values indicated in Fig. 5/5a.

Fitting the external mechanical sensor and relative support
(if available)
Refer to the instructions provided with the kit, code 8-21100239 EXTERNAL MEASURING
SENSOR+SUPPORT+INNERCABLE.
Assembly of the ultrasonic sensor and its “optional accessory
supplied on request” support for automatic width measurement
(Only for machines equipped with the RPA programme and wheel
guard)
- Insert the ultrasonic sensor cable inside the slots in the metal pipe (see fig.7) fixing
the cable using the supplied hose clamp
(A, fig.7).
- Fasten the ultrasonic sensor to the guard
pipe with the three supplied M8 screws
(Fig.7a).
- Connect the sensor cable to the connector
on the side of the casing (A, fig.7b).
IMPORTANT: after installing the ultrasonic
sensor, calibrate the sensor as described
in the paragraph “Calibrating ultrasonic
width measuring sensor”.
After installing the machine, move into the
selected location, ensuring that the spaces
surrounding the machine comply with the
minimum dimensions indicated in Fig. 5a.

ELECTRICAL HOOK-UP
On request, the wheel balancer can be set up by the manufacturer to operate with the power
supply available in the place of installation. The set-up data for each machine are given on
the machine data plate and on a special label attached to the power supply connection cable.
CAUTION
Any operations for hooking up to the workshop electrical board must be carried out only by
qualified technicians in compliance with the regulations in force, under the responsibility
and at the charge of the customer.
- The electric hook-up must be performed according to:
