41.8 Possible causes:
Heavily worn material hoses
Poorly lubricated material hoses
Residual water in mortar hose
Clogging of pressure flange
Steep tapering of the couplings
Kink in mortar hose
Leaks in the couplings
Unmixed materials or materials unsuitable for pumping
41.9 Pre-existing damage on mortar hose
NOTE!
Should a machine malfunction due to a blockage
cause the pressure in the mortar hose to only briefly
exceed 60 bar, replacement of the mortar hose is
recommended, since unseen damage to the hose
cannot be ruled out.

DANGER!
Danger due to escaping material!
Never detach hose couplings if the feed pressure has
not been fully released! The conveyed material can
escape under pressure and lead to serious injuries,
especially eye injuries.
In accordance with the accident prevention regulations
of the Builder’s Guild, all personnel clearing
blockages should wear personal safety equipment
(safety goggles, protective gloves) and position
themselves so as not to be hit by escaping material.
Other persons are not permitted in the vicinity.
