2.9 Safety and protective devices
The machine is equipped with various protective devices. The protective
devices with which the operating personnel comes into direct contact are
listed below.
Non-functioning, bridged or decommissioned safety and protective devices
do not protect against the hazards and can lead to severe injuries or death.
− Always check that all protective devices are installed correctly and
functional before starting work.
− Never decommission protective devices.
2.9.1 Emergency stop button
The emergency stop button (1) is a pushbutton, which serves to switch off
the machine in an emergency. As soon as the emergency stop button is
pressed, the drive motor stops and the compressed air supply to hydraulics
and compressor is closed.
We recommend closing the levers for the upper and lower air (see Section
4.6) beforehand, if possible.
After an emergency stop has been triggered, mixing and delivery vessel and
the delivery hoses must be cleaned immediately.
Function test
1. Press the emergency stop button while the machine is running.
2. The machine switches off.
If the machine does not switch off, the safety switch is defective and
must be repaired before the machine is put into operation.
