13.0 MAINTENANCE
13.1 GENERAL
CAUTION
Before performing any maintenance operations, make sure the machine has been
disconnected from the mains power supply. Always use the Personal Protective
Equipment indicated in the Installation Manual.
13.1.1 Introductory notes
This machine has been designed so as not to require routine maintenance, apart from accurate periodic cleaning.
It is important to keep the machine perfectly clean in order to prevent dust or impurities from compromising the
operation of the balancer.
WARNING
The 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.
13.1.2 Safety rules
Performing specialist activities on the equipment, particularly 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 Equipment indicated in the Installation Manual. During
activities, 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.
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 attention.
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 during
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.
13.1.3 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.
