at mains pressure as soon as a basket arrives underneath the rinsing nozzles, and
has to stop when the basket exits. It is advisable to check this when the booster tank
water is cold.
f) Check operation of the machine’s limit switch, which has to block operation of
the feed motor and pump when a basket reaches the end of the surface. Operation
must resume when the basket is removed.
g) Check the sense of rotation of the motors. If they turn against the arrow shown on
the towing actuator, reverse a phase in the power cable socket-outlet.
CAUTION: If the towi g tur s agai st the directio of the arrow show , the
mecha ical safety device is ot worki g.
Failure to comply with these checks automatically causes the warranty to be forfeited
