DANGER!
Overpressure on the machine!
When opening machine components, these can
fly open in an uncontrolled manner and injure
the operator.
Only open the mortar hoses if the mortar pressure
gauge (1) indicates the pressure has fallen to “0 bar”.
DANGER!
Danger of injury due to leaking mortar!
Escaping mortar can lead to injuries to the eyes
and face.
Therefore:
