1.0 GENERAL INTRODUCTION
This manual is an integral part of the product and
must be retained for the whole operating life of the
machine.
Carefully study the warnings and instructions con-
tained in this manual. It contains important instruc-
tions regarding FUNCTIONING, SAFE USE and
MAINTENANCE.
KEEP THE MANUAL IN A KNOWN,
EASILY ACCESSIBLE PLACE FOR
ALL ACCESSORY OPERATORS
TO CONSULT IT WHENEVER IN
DOUBT.
THE MANUFACTURER DISCLAIMS
ALL RESPONSIBILITY FOR ANY
DAMAGE OCCURRED WHEN THE
INDICATIONS GIVEN IN THIS
MANUAL ARE NOT RESPECTED:
AS A MATTER OF FACT, THE NON-
COMPLIANCE WITH SUCH INDI-
CATIONS MIGHT LEAD TO EVEN
SERIOUS DANGERS.
1.1 Introduction
Thank you for preferring this device. We feel sure you
will not regret your decision.
This accessory has been designed for use in profes-
sional workshops and stands out for its reliability
and easy, safe and rapid operation: with a minimum
maintenance and care this device will operate for many
years without problems, thus satisfying Your needs.
2.0 INTENDED USE
The accessory GAR324 - GAR325 is a lateral lift-
ing device to be assembled as an option on the
wheel balancers of the new series except for models
VSB33X, and it is intended for use as an aid during
the positioning and removal of the wheel (max. 80
kg) from the chuck.
With GAR324 device the lifting device is equipped
with load balancing. The weight of the lifted wheel
can be "stored" by means of a pedal control: in this
way the effect of the weight is undone during the
centring operation on the wheel balancer shaft and
so the centring on the mandrel is improved during
the blocking.
DANGER: USING THESE DEVICES
OUTSIDE OF THE INTENDED USE
FOR WHICH THEY HAVE BEEN
DESIGNED (INDICATED IN THIS
MANUAL) IS INAPPROPRIATE AND
DANGEROUS.
THE MANUFACTURER CANNOT
BE HELD RESPONSIBLE FOR ANY
DAMAGE CAUSED BY IMPROPER,
ERRONEOUS, OR UNACCEPTABLE
USE.
AN INTENSIVE USE OF THE DE-
VICE 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 device and 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 manufacturer.
A CAREFUL READING OF THIS
INSTRUCTION MANUAL FOR
USE AND MAINTENANCE AND A
SHORT PERIOD OF TRAINING
WITH SKILLED PERSONNEL CAN
BE AN ENOUGH PREVENTIVE
PREPARATION.
