3. Detach the spirals and the relative flang-
es from the two motors.
4. Disconnect the left motor from the wiring
and remove it from the tray. In its place, fit
the bush support and the pin bush.

5. Hook the spiral guides to the tray base to
enable the spirals to remain straight dur-
ing the rotation
6. First, mount the right-hand and left-hand
spirals with the same pitch onto the new
flanges (the right one and the left one are
the same), fitted with a transmission gear
wheel. Then, couple the right-hand one
with the motor still on the tray and the
left-hand one with the bushes you have
mounted before.
The two gear wheels must mesh.

7. Remove the labels no longer used from
the trays with selection / price labels; if
necessary, move the others and update
the ones still in use.
The selection / price displays of trays are
automatically configured once again.
8. Set the sales price you wish for the new
selections.
9. Test the modified selections to be sure
they are properly working.
Please Note: The selection numbers are
formed by two digits; the first digit refers
to the tray number, counting from the top
(1-7), the second digit refers to the spiral
number, counting from the left (0-10).
The selection number to which the motor is
connected will be therefore formed by the
tray number plus the wire code number.
