Measures at the end of work and during cleaning
WARNING!
Before removing the screw pump and opening the motor tilt flange, make
absolutely sure the pump and hoses are depressurised.
Observe the mortar pressure gauge display.
Switch off the mortar supply (star wheel) and turn the star wheel (1) switch
to “0” at the end of work.
Empty the mixing tube.
Press the red “Operation OFF” pressure switch (2).
Switch off the compressor and open the tap on the spraying gun.
Disconnect the mortar hose (only if depressurised).
Release the snap lock (1) on the motor flange and tilt the motor.
Remove the mixing shaft (2) and clean it.
Clean the mixing area with a spatula.
Insert the cleaning shaft and mixing tube cleaner with the scrapers pointing
downwards.
Close the motor flange and lock it with the snap lock.
Press the green “Operation ON” pressure switch about 5-10 seconds and
let the motor run until the mixing tube is clean.
Press the red “Operation OFF” pressure switch and remove the mixer
cleaner.
Install the cleaned mixing shaft. Close the motor flange and lock it with the
snap lock.
To clean the hoses, they are connected together with the mortar pressure
gauges to the water outlet valve using the cleaner coupling (in the tool
bag). This protects the pump from damage. First a water-soaked sponge
ball must be pressed into the hose inlet.
