DANGER!
Danger from discharged material!
Never loosen the hose couplings as long as the
pressure head is reduced! Material to be conveyed
can be discharged under pressure and cause injuries
particularly to the eyes.
Persons commissioned with the cleaning of clogged
hoses have to wear personal protective equipment
(protective goggles, gloves) for safety reasons, and to
position themselves in such a way that they cannot be
hit by discharged material. Other persons have to
clear the area.
