1.- PRIOR INSPECTION BEFORE OPENING THE MACHINE

1.1.- Check machine operation. The machine will be switched on with all external parts properly assembled to check

operation. It is necessary to double check if the cups go down rhythmic and symmetrical and that no obstacle is observed

when descending.

1.2.- Check machine synchronization. Check that the machine is

properly aligned by manually moving the motor with the Allen key,

placed on the machine´s base, until the outer centre rod of the basket

coincides with the hopper basket rod. At this point the cups should

remain in the vertical position.

Once the alignment has been verified, move the machine manually

until the cups start moving downwards and check if there is any play

in the cups shaft.

1.3.- Check all external parts and the classifiers use. Check that all the external parts are working properly (Double check

the errors messages on the display).

1.3.1 Verify magnet’s condition on all parts:

1.3.2 Check filter tray and pulp scraper status double check when the machine

is completely assembled that it moves properly. It can be checked looking by

the hole underneath the filter tray.

1.3.3 Check squeezing tray condition. Unscrew both balls and check if we have

both Teflon washers underneath the balls. Verify both threads status and that

there is no separation between the ball base, the washer and the thread base.

1.3.4 Check if we have the Allen key to unblock the machine and move it

manually. It must be underneath the machine.

1.3.5 Check the properly use of both classifiers, the upper and lower one. If working with the medium size cups (53 /

76) we must use the upper classifier with the same size and lower separator at the same position show on picture

below.

Classifier 53/76 Lower classifier

1.4.- Check ventilation. Must be checked that the fan turns on every time the motor is operating.

Check power input plug, cable and fuse holder (Verify if there is one 6A fuse in backup).

1.5.- Note cycles Reading. The number of cycles must be note to have the

count of the cycles done since the last inspection. To view them, the

machine must be properly assembled then press STOP and the number of

cycles will be shown on the screen.

2.- MACHINE DISMANTLING AND INTERNAL INSPECTION

2.1.- Check all the hopper track screws condition. Dismantle the machine following point 3 of the technical instructions.

Double check all screws condition while being removed. Once the Hopper track has been removed, we will be able to

disassemble the machine front.

2.1.1 Check the ring gasket of the basket shaft. When removing the caps (3/9/1G), unscrew the 4 cross head screws

and check the rubber washer condition of each one, considering that when re-screwing them don’t forget the washer.

2.2.- Check machine body bolts. Unscrew both hexagon bolts (I-933-M6X10) which fixes the front (210239) to the chassis

(210101). Loosen one turn each one of the four legs in order to remove the front and then the rear.

2.3.- Check the wiring and interconnection plugs. Once the hopper track is released, lift it carefully and unplug both from

the interconnections box. Double check both plugs and wiring status. To be able to remove the machine we must

disconnect the power input, ground connection and fan cables.

2.4.- Check the slide cover set. Get loose the 6 screws which fix the slide cover

set and double check its status.

2.5.- Check the pushing plate set (210447). Verify both hexagon socket countersunk Allen screws (I-7991-M6X16). The

hexagonal bolt (T-933-M8X20) which fixes the connecting rod (210411) to the pushing plate set must be also checked

and verify if its properly tight.

2.6.- Check both ratchets condition. We must check if

both are well greased, if the four safety rings (T-471-

E14) are in good condition and if both ratchets have all

their soundproof plugs (blue arrows).

With the connecting rod on its vertical position verify

that the chassis closure screws (I-933-M8X35) are

securely tight. Then verify if the shafts have any play, in

case they have, both bolts must be adjusted.

2.7.- Check both wedges (R-210449A / L–210448A) condition. We must release

the spring and check if the four wedges rotate freely without any rub, if they are

properly greased and check the four E-18 safety rings (T-471-E14).

Check the pushing plate supplement (210430) condition. If it’s damaged proceed

to replace by a new one.

2.8.- Check both ratchet springs. Double check with the connecting rod on its higher vertical position that there is a

distance higher than 1,5 mm. between the wedge and the ratchet. *

*Check the pushing plate play. To check it take the pushing plate down until the ratchets don’t touch it.

2.9.- Verify both cup shafts (210504A). Check that we haven’t got any play in both shafts

and that they have the safety rings (I-471-E28) in good condition. Release the safety ring.

2.9.1 Once we have removed the safety rings of both cup shafts, push each shaft inwards, as seen in the pictures and

grease the part which is inserted inside the slider.

2.10.- Check feeder condition. We must check that the feeder safety ring (I-471-E20) which fixes the conical crown set

and that the chain (210323) is not loose. Remove the safety ring (I-471-E20), release the crown and check that the crown

wheel base washer (210353) below is in good condition.
