blockage.
EFFECT
High pressure (over 12 bar) indicated by the line manometer, as well as the non-escape of material from the gun.
CAUSE
- Mixture too thin.
- Material deposits
- Stone inside the gun
- Deflector with passage too narrow in relation to the particle size of the mixture.
SOLUTION
- Stop the machine using the master switch.
- Discharge the pressure in the material flow pipes by turning the by-pass lever to a vertical position (FIG.40-REF.1).
- Wait for the pressure indicated by the manometer (FIG.40-REF.2) to fall to zero.
Always discharge the pressure in the piping before disassembling the deflector or the gun. The line manometer
must indicate a pressure of zero bar. On trampling the mortar piping must go limp.
- Disassemble the deflector and if necessary the gun and remove the cause of the blockage.
- Before re-mounting the deflector or the gun, make sure that the nozzle is free (clean it if necessary using wire).
- Re-start the machine to check that the material escapes freely from the piping.
