1 - General safety information
This document provides information about handling, installation and maintenance of helical and bevel helical
gear reducers and gearmotors (G series).
All the people involved in these activities will carefully read and follow all present instructions.
Information and data contained in this document correspond to the technical level reached at the moment
the catalog is printed. Rossi reserves the right to introduce, without notice, the necessary changes to improve
effi ciency and safety of its products.
1.1 - Recycling
Keep in mind the instructions in force concerning exhaust disposal and recycling:
–
elements of gear reducer housing, gear pairs, shafts and bearings must be transformed into steel
scraps along with all other cast iron components, excluding specifi c cases;
– for all other non-metallic components (seal rings, caps, etc.) follow the instructions in force;
–
all exhaust oils must be recycled and treated as per regulations in force.
1.2 - Safety
The paragraphs marked with symbols shown below contain dispositions to be strictly respected in order to
assure personal safety and to avoid any heavy damages to the machine or to the system.
(Electric or mechanical) danger, such as:
– live parts;
– temperature higher than 50 °C;
– components rotating during operation;
– suspended loads (lifting and transport);
– eventual high sound level ( 85 dB(A)).
IMPORTANT: gear reducers and gearmotors supplied by Rossi are components to be incorporated into
machinery and should not be commissioned before the machinery in which the components have
been incorporated conforms to:
– Machinery directive 2006/42/EC and subsequent updatings; in particular, possible safety guards
for shaft ends not being used for eventually accessible fan cover passages (or other) are the
Buyer's responsibility;
– «Electromagnetic compatibility (EMC)» 2004/108/EC and subsequent updatings.
Attention! It is recommended to pay attention to all instructions of present handbook, all standards
concerning correct installation and all existing safety laws. Whenever personal injury or property
damage may occur, foresee adequate supplementary protection devices against:
− release or breakage of fastening screws;
– rotation or unthreading of the gear reducer from shaft end of driven machine following to accidental
breakage of the reaction arrangement;
– accidental breakage of shaft end of driven machine.
If deviations from normal operation occur (temperature increase, unusual noise, etc.) immediately
switch o the machine.
Installation
An incorrect installation, an improper use, the removing or disconnection of protection devices, the lack of
inspections and maintenance, improper connections may cause severe personal injury or property damage.
Therefore the component must be moved, installed, commissioned, handled, controlled, serviced and re-paired
exclusively by responsible qualifi ed personnel.
The qualifi ed personnel must be specifi cally instructed and have the experience necessary to recognize and
prevent dangers connected to present products avoiding all possibile emergencies.
Gear reducers and gearmotors of present handbook are normally suitable for installations in industrial areas:
additional protection measures, if necessary, must be adopted and assured by the personnel responsible for the
installation.
Attention! Components in non-standard design or with special executions or with constructive variations may
diff er in the details from the ones described here following and may require additional information.
Attention! For the installation, use and maintenance of the electric motor (standard, brake of non-standard
motor) or of the eventual motor variator and/or electric supply device (frequency converter, soft-start etc.), and/
or optional electric devices (e.g.: independent cooling unit, etc.), consult the attached specifi c documentation. If
necessary, require it.
Maintenance
When operating on gear reducer or on components connected to it the machine must be at rest: disconnect
motor (including auxiliary equipments) from power supply, gear reducer from load, be sure that safety systems
are on against any accidental starting and, if necessary, pre-arrange mechanical locking devices (to be removed
before commissioning).
Attention! During the running the gear reducers could have hot surfaces; always wait that the gear reducer or
the gearmotor to cool before carrying out any operations.
