Recycling (observe established legislation):
– casings, gears, shafts and bearings of gear reducer
must be handled as scrap iron materials, along with all
other steel components;
– worm gears have a bronze crown and must be handled as bronze
waste material, along with other bronze components;
– all other non-metallic components (O-rings, caps, etc.) must be
handled as required by established legislation;
– exhausted oils must be collected and handled as required by esta-
blished legislation.
Electric or mechanical danger
Safety instructions for the use in areas classified accor-
ding to ATEX 99/92/EC
The paragraphs marked with the above mentioned symbols contain
dis positions to be strictly respected in order to assure per sonal
safety and to avoid any heavy damages to the machine or to the
system (e.g.: works on live parts, on lift ing machines, etc.); the
responsible for the installation or maintenance must scrupulously
follow all instructions contained in present handbook.
1 - General safety instructions
Gear reducers and gearmotors present dangerous parts because
they may be:
– live;
– at temperature higher than +50 °C;
– rotating during the operation;
– noisy (sound levels > 85 dB(A)).

An incorrect installation, an improper use, the removing
or disconnection of protection devices, the lack of inspec-
tions and maintenance, improper connections may cause
severe personal injury or property damage. Therefore the
component must be moved, installed, commissioned, handled, con-
trolled, serviced and repaired exclusively by responsible quali-
fied personnel (definition to IEC 364).
It is recommended to pay attention to all instructions of present
handbook, all instructions relevant to the system, all existing safety
laws and standards concerning correct installation.
Components in non-standard design or with constructive variations
may differ in the details from the ones described here following and
may require additional information.
For any clarification and/or additional information consult ROSSI
MOTORIDUTTORI and specify all name plate data.
The technical catalogues may be consulted from web site (www.
rossi-group.com) or requested to ROSSI MOTORIDUTTORI.
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.
IMPORTANT: the components supplied by ROSSI MOTORIDUTTO-
RI must be incorporated into machinery and should not be com-
missioned before the machinery in which the components
have been incorporated conforms to:
– Machinery directive 98/37/EC; in particular, possible safety
guards for shaft ends not being used and for eventually
accessible fan cover passages (or other) are the Buyer's
responsibility;
– «Electromagnetic compatibility (EMC)» directive 89/336/EC
and subsequent updatings.
Important: for the installation, use and maintenance of the electric
