2.0 INTENDED USE
The machines models G3.140R - GP3.140R -
G3.140RS - GP3.140RS, and relative versions,
are wheel balancers for car and light transport,
projected to be used exclusively to cancel out, or at
least reduce to acceptable limits the vibrations of the
wheels, by fitting counterweights of suitable size and
in specific positions to the same wheels that are not
correctly balanced.
DANGER: THIS MACHINE MUST
BE USED STRICTLY FOR THE
INTENDED PURPOSE IT WAS DE-
SIGNED FOR (AS INDICATED IN
THIS MANUAL).
THE MANUFACTURER CANNOT
BE HELD RESPONSIBLE FOR ANY
DAMAGE CAUSED BY IMPROPER,
ERRONEOUS, OR UNACCEPTABLE
USE.
AN INTENSIVE USE OF THE EQUIP-
MENT IN INDUSTRIAL ENVIRON-
MENT IS NOT RECOMMENDED.
2.1 Staff training
The machine may be operated only by suitably
trained and authorized personnel.
Given the complexity of the operations necessary to
manage the machine and to carry out the operations
safely and efficiently, the personnel must be trained
in such a way that they learn all the information
necessary to operate the machine as intended by the

3.0 SAFETY DEVICES
• Master switch positioned on the rear of the ma-
chine
Its function is to disconnect machine electric supply.
• Protection guard
Its function is to protect the operator from possible
projections of materials on the wheel during its spin.
Wheel spinning is normally prevented if the wheel
protection guard is raised (open). When the
protection guard is open, this interrupts the cir-
cuit that triggers the motor and automatic start
is prevented, including in the case of an error.
Press stop key to stop wheel rotation in
emergency conditions.
3.1 Residual risks
The machine was subjected to a complete analysis of
risks according to reference standard EN ISO 12100.
Risks are as reduced as possible in relation with tech-
nology and product functionality.
Possible residual risks have been emphasized through
pictorial representations and warnings which placing is
indicated in “ PLATE POSITIONING TABLE” at page 6.
4.0 GENERAL SAFETY RULES
• Any tampering with or modification to the machine
not previously authorized by the manufacturer ex-
empts the latter from all responsibility for damage
caused by or derived from said actions.
• Removing of or tampering with the safety devices or
with the warning signals placed on the machine leads
to serious dangers and represents a transgression of
European safety rules.
• Use of the machine is only permitted in places free
from explosion or fire hazard and in dry places
under cover.
• Original spare parts and accessories should be used.
THE MANUFACTURER DENIES
ANY RESPONSIBILITY IN CASE
OF DAMAGES CAUSED BY UNAU-
THORIZED MODIFICATIONS OR
BY THE USE OF NON ORIGINAL
COMPONENTS OR EQUIPMENT.
• Installation must be conducted only by qualified
personnel exactly according to the instructions that
are given below.
• Ensure that there are no dangerous situations dur-
ing the machine operating manoeuvres. Immediately
stop the machine if it miss-functions and contact the
assistance service of an authorized dealer.
• In emergency situations and before carrying out any
maintenance or repairs, disconnect all supplies to
the machine by using the main switch, placed on the
machine itself, and unplugging the power supply.
• The machine electrical supply system must be
equipped with an appropriate earthing, to which
the yellow-green machine protection wire must be
connected.
• Ensure that the work area around the machine is free
of potentially dangerous objects and that there is no
oil since this could damage the tyre. Oil on the floor
is also a potential danger for the operator.
• UNDER NO CIRCUMSTANCES must the machine be
used to spin anything but vehicle wheels. Bad locking
can cause rotating parts to come loose, with potential
damage to the machine and anything in the vicinity
and injury to the operator.

10.0 ELECTRICAL CONNECTION
EVEN THE TINIEST PROCEDURE
OF AN ELECTRICAL NATURE
MUST BE CARRIED OUT BY PRO-
FESSIONALLY QUALIFIED STAFF.
BEFORE CONNECTING THE MA-
CHINE MAKE SURE THAT:
• THE MAIN POWER RATING COR-
RESPONDS TO THE MACHINE
RATING AS SHOWN ON THE
MACHINE PLATE;
• ALL MAIN POWER COMPO-
NENTS ARE IN GOOD CONDI-
TION;
• THE ELECTRICAL SYSTEM
IS PROPERLY GROUNDED
(GROUND WIRE MUST BE THE
SAME CROSS-SECTION AREA
AS THE LARGEST POWER SUP-
PLY CABLES OR GREATER);
• MAKE SURE THAT THE ELEC-
TRICAL SYSTEM FEATURES A
CUTOUT WITH DIFFERENTIAL
PROTECTION SET AT 30 mA.
Connect the machine up to the mains by means of the
3-pole plug provided (230 V single-phase) through the
wall socket.
If the plug provided is not suitable for the wall socket,
fit a plug that complies with local and applicable regu-
lations. This operation must be performed by expert
and professional personnel.
FIT A TYPE-APPROVED (AS RE-
PORTED BEFORE) PLUG TO THE
MACHINE CABLE (THE GROUND
WIRE IS YELLOW/GREEN AND
MUST NEVER BE CONNECTED TO
THE PHASE LEADS). MAKE SURE
THAT THE ELECTRICAL SYSTEM
IS COMPATIBLE WITH THE RATED
POWER ABSORPTION SPECIFIED
IN THIS MANUAL AND APT TO
ENSURE THAT VOLTAGE DROP
UNDER FULL LOAD WILL NOT
EXCEED 4% OF RATED VOLTAGE
(10% UPON START-UP).

FAILURE TO OBSERVE THE ABOVE
INSTRUCTIONS WILL IMMEDIATE-
LY INVALIDATE THE WARRANTY.
10.1 Electrical checks
BEFORE STARTING UP THE
WHEEL-BALANCER, BE SURE TO
BECOME FAMILIAR WITH THE LO-
CATION AND OPERATION OF ALL
CONTROLS AND CHECK THEIR
PROPER OPERATION (SEE PAR.
“CONTROLS”).
CARRY OUT A DAILY CHECK OF
MAINTAINED-TYPE CONTROLS
CORRECT FUNCTIONING, BEFORE
STARTING MACHINE OPERATION.
Once the plug/socket connection has been made, turn
on the machine using the master switch (Fig. 23
ref. 1).
11.0 AIR CONNECTIONS
Only for GP3.140R - GP3.140RS models
IN CASE OF A CHANCE SUP-
PLY FAILURE, AND/OR BEFORE
ANY PNEUMATIC CONNECTIONS,
MOVE THE CONTROLS TO THE
NEUTRAL POSITION.
Connect the wheel balancer to the centralised com-
pressed-air system by means of the connection on the
back of the machine (see Fig. 24).
The air system supplying the machine must be able
to supply filtered and de-humidified air at a pressure
between 8 and 10 bar. It must feature an on-off valve
upstream of the machine.

4. Fit the protection cap (Fig. 26 ref. 1) in the locknut
(Fig. 26 ref. 2) and fasten against the wheel.
Fig. 25
Fig. 26
Fig. 27
Some aluminium wheels, with very high centring, must
be fitted with the cone outside the wheel.
5. Clean the mandrel (Fig. 27 ref. 1) before fitting
the wheel.
6. Fit the wheel (Fig. 27 ref. 3) with the inside of the
rim towards the wheel balancer, until the wheel is
up against the support flange (Fig. 27 ref. 2).
12.0 FITTING THE WHEEL ON THE
MANDREL
To achieve perfect balancing, the wheel must be care-
fully and properly fitted on the mandrel. Imperfect
centring will inevitably cause unbalances.
MOST IMPORTANT IS THAT ORIGI-
NAL CONES AND ACCESSORIES
ARE USED MADE SPECIFICALLY
FOR USE ON THE WHEEL BAL-
ANCER.
Wheel fitting using the cones provided is illustrated be-
low. For alternative fittings, using optional accessories,
refer to the special instructions provided separately.
12.1 Fitting of the wheel (G3.140R - G3.140RS)
1. Remove any type of foreign body from the wheel
(Fig. 25 ref. 3): pre-existing weights, stones and
mud, and make sure the mandrel (Fig. 25 ref. 1)
and the rim centring area are clean before fitting
the wheel on the mandrel.
2. Carefully choose the cone (Fig. 25 ref. 2) most suit-
able for the wheel to be balanced. These accessories
must be selected according to the shape of the rim.
Position the wheel (Fig. 25 ref. 3), fitting the cone
(Fig. 25 ref. 2) on the mandrel (Fig. 25 ref. 1): be
careful (otherwise this could seize) until this rests
against the support flange (Fig. 25 ref. 4).
3. Fit the wheel with the inner side of the rim towards
the wheel balancer and against the cone.
