- Keep all parts of body and/or tools clear of mixing drum
during operation.
Accident prevention standards and safety regulations must be
observed at all times in the work area.
When handling the components required to prepare the mixes,
take care not to raise dust that might be inhaled; should it be
impossible to avoid this, wear a protective mask over the mouth

-
The concrete mixer must never be used in areas at
ULVNIRUH[SORVLRQVRU¿UHVRULQXQGHUJURXQGH[FDYDWLRQV
The concrete mixer is not equipped with lights, and therefore the
area where it is used must be well-lit.
Power supply lines must be installed where they will not be subject
to damage.
Do not stand the cement mixer on the electrical power cable.
Connection must avoid any contact of plugs with water. Only use
plugs and sockets with protection against water spray.
- Do not use electrical lines that are undersized, makeshift or
without the earth wire.

The concrete mixer is also equipped with a safety device to prevent
accidental electrical contacts, with class II dual insulation of all live
parts. For this reason it does not require to be earthed.
- CAUTION: when carrying out repairs, class II protection
will only be maintained if original insulating materials are
