Clearing hose blockages
WARNING!
In accordance with the safety regulations of the Builder’s Guild, all personnel
engaged in clearing hose blockages should wear safety goggles and should
position themselves in such a way as to avoid being struck by discharged mortar.
Switch off star wheel motor (1)
Run pump motor briefly in reverse, and in doing so:
Cover outlet opening of pump tube with foil
“Reverse” (2) (water supply is automatically interrupted) until pressure at mortar
pressure gauge has fallen to 0 bar
Loosen nut on pressure flange slightly so that any residual pressure is released, detach
hose coupling and clean hose
To remove residual mortar from the mortar hose, see page 20 “Cleaning the hose”
Measures to be taken in the event of a power failure
WARNING!
Make sure all hoses are depressurised before opening the couplings (observe the
mortar pressure gauge indicator).
The mortar hoses must be cleaned immediately. They can be cleaned at the water
bleeder valve. To do so, connect the plaster coupling (in the tool bag) to the mortar
hose first and then to the water bleeder valve. Force the mortar out by opening the
water valve and then clean with water-soaked sponge balls.
Release the tie rod screws, remove the pump, push the rotor out of the stator and clean
it thoroughly. Clean the pressure flange or agitator (ROTOMIX or ROTOQUIRL). Clean
the mixing area and the mixing shaft with water and a spatula. Then assemble the entire
pump and prepare it for operation.
