You can switch the machine on or off by either opening or shutting the ai
tap on the spraying gun.
NOTE:
While working without air supply (e.g. pumping floor screed), the machine is
switched on and off by a 42 V remote control. To do this, remove the blind
plug on the control coupling and connect control plug of the remote control.
.
Mortar Consistency
The mortar consistency is right when the material on the surface being sprayed flows into itsel
forming a consistent coat. Apply material on wall surfaces from top to bottom. If the water quantity
is not enough, even mixing and spraying cannot take place. There may be clogging in the hose.
Pumping components are thus subject to greater wear and tear.
Spraying Guns and Caps
Use spraying caps of 10, 12, 14, 16 oder 18 mm depending on the mortar consistency. Large
caps reduce the projection speed and the rebound effect. Smaller caps create better atomization.
Note that the gap between the air nozzle tube and the spraying cap should correspond to the
diameter of the spraying cap.
.
Interruption of Spraying Operation
Follow all instructions of mortar manufacturer while interrupting spraying
operations.
Clean the pump before long interruptions.:
See Procedures at the End of Work and Cleaning, page 21 for more
information.
Every interruption of the spraying operation causes a slight irregularity in
the mortar consistency. This generally normalizes itself once the machine is
restarted. Do not keep on changing the water quantity at every irregularity.
Wait till the mortar consistency at the spraying gun has regulated itself
again.
