This machine is equipped with an agitator safety cutout. As soon as
you open the grille, the signal between the transponder and reading
head is broken. This causes the agitator to halt and the pressure to
be dumped from the accumulator, i.e. the transfer tube will no longer
be able to switch over. In addition, the delivery pistons return to the
end position and the concrete pump halts.
Danger
Risk of injury when the agitator is operating and the transfer tube is
switching.
A defective agitator safety cutout can cause you to believe that the
machine is safe, even though this is not really the case. This can
lead to the agitator continuing to run or the transfer tube switching
over when the grille is open.
You must therefore check the function of the agitator safety cutout
before you start each pumping job.
Before acknowledging the agitator safety cutout, check that noone
is in any danger.
You must stop work if you open the grille, but
the agitator continues to run, or
the transfer tube continues to switch over, or
the concrete pump does not run to its end position.
