52.2 Causes of clogged hoses:
Heavily worn mortar hoses
Interruptions in work
Poorly lubricated mortar hoses,
Residual water in mortar hose
Clogging of pressure flange
Steep tapering of the couplings,
Kink in mortar hose
Unmixed materials or materials unsuitable for pumping.
52.3 Pre-existing damage on mortar hose
NOTE!
Should a machine malfunction due to blockages 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.
