9.3
Obligation of the operators
People who work on the machine must observe the relevant safety regulations concerning working safety
and accident prevention before starting work; must read the safety chapter and the warning notes in
these operating instructions.
9.4
Personnel training
Only trained people may work on the machine. Their responsibilities must be defined clearly for
assembly, start-up, operation, setting, maintenance and repairing.
9.5
Safety measures
The operating instructions must be kept with the machine. General and local regulations for accident
prevention and environmental protection, and the operating instructions, must be observed. Safety and
danger warnings on the machine must be legible.
9.6
Dangers when handling the machine
The MasoSine pump is built according to state-of-the-art principles and the recognised safety engineering
rules. Nevertheless, danger to life and limb of the user or third persons, or impairments to the machine or
to other assets, can arise in its use.
The machine must be used only:
l
for its intended use
l
if it is in a safe engineering condition.
Faults which may compromise safety must be rectified immediately.
9.7
Safety measures in normal operation
Operate the machine only if all protective devices are functioning. Before switching the machine on make
sure that no one can be endangered when the machine starts. At least once per shift inspect the machine
for damage and for proper functioning of the safety devices.
9.8
Protective devices
All protective devices must be attached correctly and functioning before every start- up. Protective
devices may be removed only after the machine has stopped and protection measures against restarting
the machine have been taken.
After spare parts have been fitted, protective devices must be attached according to the operating
organisation’s regulations.
If contact with hot or cold machine parts could be dangerous, protection must be provided for the pump
user.
9.9
Dangers due to hazardous pumped material
If hazardous material is to be pumped, the appropriate regulations must be observed.
9.10 Dangers due to electrical energy
Work on the electrical supply must be performed only by an electrician.
Check the electrical equipment of the machine regularly. Rectify loose connections
and scorched cables immediately.
Keep the control cabinet locked closed or secured with a tool. Access is allowed only to authorised
personnel.
If work on parts conducting voltage must be done, call in a second person to switch off the mains power if
necessary.
Electrical connection of the pump must be made according to local regulations, by skilled personnel only.
9.11 Dangers due to hydraulic energy
Only personnel with special knowledge and experience in hydraulics may work on hydraulic devices.
Relieve the pressure in the system sections and pressure lines to be opened before starting repair work.
Replace hydraulic hose lines at appropriate intervals, even if no safety-relevant defects are detectable.
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.
