8.1.1 Introductory notes
This machine has been designed so as not to require rou-
tine maintenance, apart from accurate periodic cleaning.
It is important to keep the machine perfectly clean in or-
der to prevent dust or impurities from compromising the
operation of the balancer.
WARNING
T HE PEOPLE RESPONSIBLE FOR CLEANING THE AREA WHERE THE
MACHINE IS INSTALLED MUST WEAR PERSONAL PROTECTIVE EQUIPMENT
IN ORDER TO WORK IN SAFETY AND ACCORDING TO THE CURRENT
OCCUPATIONAL HEATH AND SAFETY REGULATIONS
.
As extraordinary maintenance must be performed by service
staff or, in any case, by specifically authorised and trained
people, is not dealt with in this manual.
8.1.2 Safety rules
Performing specialist activities on the equipment, particu-
larly if the guards need to be dismounted, exposes people
to serious danger due to the presence of potentially live
parts.
The rules shown below must be scrupulously followed.
People must always use the Personal Protective Equip-
ment indicated in the Installation Manual. During activi-
ties, unauthorised people may not access the equipment
and WORK IN PROGRESS signs will be erected in the
department in such a way that they are visible from every
place of access.
8. Maintenance
Specialist staff must be authorised and especially trained
concerning the dangers that may arise during operation
and the correct methods for avoiding them.
They must always work with great care and pay full at-
tention.
If, exceptionally, the staff removes the guards to carry out
a particular specialist technical maintenance, inspection
or repair job, they are required to put them back after
work.
After work, staff must make sure that foreign objects, in
particular mechanical pieces, tools or devices used dur-
ing the operative procedure that could cause damage or
malfunctions are not left inside the balancer.
For safety, before starting work, maintenance, inspection
and repair staff must disconnect all power sources and
take all the necessary preventive safety measures.
As well as operating frequencies, the operations described
below indicate the qualifications that staff must possess
in order to perform the operation.
8.1.3 Replacing fuses
Some protection fuses are located on the power board
(see wiring diagrams) accessible by dismantling the weight
shelf). If fuses require replacement, use ones with an
identical current intensity.
