If too much current is absorbed the motor protector intervenes inside the electric control board, which stops the machine.
The switches on the electric control board turn positioning themselves between 0 (zero) and I.
To insert the motor protector:
• Position the master switch (FIG.32-REF.1) in position 0 (zero). In the EMF version, before switching the machine off, put the
mortar pump motor (FIG.32-REF.2) and mixer (FIG.32-REF.3) switches at 0.

corretto) e provvedere al necessario rimedio.
• Per riavviare la macchina portare gli interruttori in posizione I.

When the last mixture has been pumped, which is better if it more fluid than normal, when the base of the mixing device can be
seen, stop the pump by closing the air flow cock, take the by-pass lever to the vertical position (FIG.40-REF.1) and check that
the manometer (FIG.40-REF.2) falls to 0 bar.
Stop the motor and place the mortar pump motor switch and the master switch (FIG.41-REF.1) in position 0.
