The position of actuator stake (6) compared to the activation (cam) disc hollow (7) has to be that the
opening of the microswith contacts (and also the stop command) occurs when the distance between the
lower edge of the cover (2) and the upper edge of the bowl is < 75 mm (for details see par.
Errore. L'origine

).
The new microswitch must have equal or better physical and performance characteristics than the replaced
one, in particular, the same dimensions and the same center distance of the fixation holes, capability to
adjust the service point as mentioned above, stable contacts clamping when the cover is lowered. If the
above is observed, no microswitch position adjustment should be needed; however, if needed, loosen the
screws (4) and nuts (5) and move the microswitch (1) by using the slots (10) until the right position is found;
after completing the adjustment, tighten the screws (4) and nuts (5).
A socket set screws (8) (dowel), is to be introduced in the hole slot of the rotation pin (9) preventing the cam
(7) from running along the pin (9); in circumferencial direction it is the square section of the pin which does
not allow the movement of the cam (7). Should it be necessary to remove the socket set screws (8), before
re-screwing it check that the threaded hole and pin slot are aligned and put just a few LOCTITE 243 or
equivalent ( thread-brake )on the dowel thread .
Check often the tightening of screws (4) and nuts (5),
and dowel (8) as well.

SPIRAL ASSEMBLY/DISASSEMBLY
The operation is to be carried out by one person only when the spiral weight does not exceed 15 Kg (see
instruction below), in other cases a simultaneous work of two operators is needed.
With reference to PicturePicture 25, to disassemble the spiral (1) proceed as follows:
- unscrew the three screws slowly taking turn with them (2) until the spiral (1) rests on the bowl bottom (3)
- hold the spiral in vertical position (1), while removing the screws (2) and washers concerned ; pay
attention not to let the cover (6) and the discs (7) and (8) fall down (re-assemble them as soon as
possible), move the spiral (1) outside the head area (4) of the base and then remove it
To re-assemble the spiral:
- position the spiral (1) in the bowl with the cover (6) and the discs (7) and (8); align the flange (9) clearance
holes with the threaded holes concerned of the head
- put the screws (2) into the clearance holes and screw them without tightening
- check visually that the spiral axis (1) is parallel to the central bar (5), and screw alternately the three screws
(2) in tightening them, and checking the parallelism of the spiral axis (1) with the central bar (5)
- switch on the machine and stand by to press the emergency button (17)Picture 2, operate the start: verify
that the spiral (1) turn on its axis without any swinging and without impacting the central bar (5), otherwise
press the emergency button and repeat the assembly operation.
ATTENTION!
Due to the weight, the spiral for models no. SPI 130 - SPI 160 - SPI 200 is to be lifted and lowered and,
in general, handled through the simultaneous work of two operators. Avoid bending the trunk as
much as possible, but flex the knees in keeping the trunk upright; this to reduce the risk of muscle-
skeletal injuries; observe the instruction given by the company employer during all training
activities regarding safety and health at work place.
