9.12 Special danger points
The pump contains a rotating rotor, which can crush or
sever fingers and hands. The pump must be guarded so
that it is not possible for people to hold the pump by its
inlet or delivery ports with the rotor running. When the
rotor is stationary, the drive must be secured against
unintentional start-up. Increased danger exists if pipes are
dismantled or the pump is open.
9.13 Constructional changes to the machine
Make no changes, attachments or conversions to the machine without the manufacturer’s approval. All
conversion measures require the written confirmation of Watson-Marlow GmbH MasoSine Division.
Replace machine parts which are not in perfect condition immediately. Use only original spare and
wearing parts. Parts that are not obtained from MasoSine are not guaranteed to be designed and
manufactured in compliance with load and safety requirements.
The warranty is invalid if genuine spare parts from MasoSine are not used.
9.14 Noise
The continuous sound pressure level proceeding from the machine should not exceed 70 dB(A). Higher
sound pressure levels that can cause deafness can arise, depending upon local conditions. If this occurs,
protect the operating personnel with appropriate protective equipment / protective measures.
