KOINE 4/5 

Prolonged shutdown can cause clogging in the material delivery 
lines:  in  this  case  no  material  is  delivered  from  the  jet  and  the 
pressure gauge (ref.3) indicates a higher pressure than the normal 
working value.
Shut down the machine by means of the stop pushbutton (ref.1d), 
position the cell wheel switch (ref.1e) to 0 and the main switch to 
the opposite settings to the normal work position (the blue lamp 
turns off) and press the inversion pushbutton for a few seconds 
(ref.1l): the mortar pump motor rotates in the opposite direction 
(the water solenoid valve (ref.13) stays closed) and the pipelines 
are depressurised (the pressure gauge reads 0 bar).
Locate the point of clogging in the hose
and remove by tapping the pipeline with a mallet.

- If necessary, disconnect the jet or open the pipeline

couplings,  checking  previously  if  any  residual  pressure  is 
present. 
The  material  pressure  gauge  must  indicate  0  bar  and  the

The personnel assigned for this task must be specially trained 
in these procedures.
In the event of any doubt as to the presence of residual pres-
sure, never open the couplings.

Reconnect the pipelines and spray jet, set the main switch to the 
correct position (the blue lamp illuminates) and restart the machine.

- Do not move the machine with the hopper full.

If the material delivered is alternately hard and soft this may indica-
te a worn pump. To replace the pump, proceed as follows: release 
the handle on the left and open the mixing chamber. Insert the 
tube wrench on the end of the mixer and unscrew until the screw 
inside the stator is released. Close the mixing chamber, tilt and 
lock in the lifted position, remove the material delivery manifold

 FIG.13

To insert the screw in the stator, use the lubricant spray available 
from IMER. Never use mineral oil or grease for screw assembly 
as this may damage the stator. Avoid all types of benzene.
In the case of a power failure during operationclean the machine 
and  pipelines  immediately  (see  para.13). Also  disassemble  the 
pump, remove the screw from the stator and clean. On completion 
reassemble all components.

13. MACHINE SHUTDOWN AND CLEANING

At the end of work, stop the cell wheel and continue pumping until 
the material delivery pipelines are empty.
Stop the machine by means of the pushbutton and set the main 
switch to 0.
Open the jet valve, detach the jet and clean thoroughly, cleaning

- Before disconnecting the jet or pipelines, ensure that

there is no residual pressure.

 Disconnect the material pipelines from the delivery manifold.
Detach the quick connector with safety device (ref.14) and open

chamber, turn the main switch to the correct position (blue lamp 
ON)  and  then  press  the  start  pushbutton.  Leave  running  for  
5-10 seconds, until the mixing chamber is completely clean.
