Clearing hose blockages
According to the accident prevention regulations of the Builders’ Guild, for
safety reasons, all personnel assigned with unblocking hoses should wear
safety goggles and position themselves in such a way as to avoid injury by
discharged mortar.
Switch off the star wheel motor (1).
Pull the blind plug (2) from the remote control.
Cover the outlet opening of the pump tube with foil.
Let the pump motor run in reverse until the pressure on the mortar pressure
gauge falls to 0 bar by turning the selector switch (3) (water supply is
automatically interrupted). Undo the nut on the pressure flange slightly to
allow the residual pressure to be released.
Undo the hose coupling and clean the hose.
Measures to be taken in the event of a power failure
The mortar hoses must be cleaned immediately. They can be cleaned at
the water outlet valve. To do so, connect the cleaner coupling (in the tool
bag) to the mortar hose first and then to the water outlet valve. Push out the
mortar by opening the water valve and then clean the hoses with sponge
balls soaked in water.
WARNING!
Make sure all hoses are depressurised before opening the couplings
(observe the mortar pressure gauge display).
