54.2 Risk of injury to due overpressure
Fig. 89: Checking the grout pressure
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:
Always wear protective goggles.
Protective clothing, protective gloves, safety shoes,
ear protection.
Always position the machine so that you cannot
be hit should mortar escape.
1. Undo both screws (2) on the pressure flange slightly to ensure
the residual pressure can escape.
2. As soon as the pressure has dropped to “0 bar”,
tighten the screws (2) again.
