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 all external spare parts status: cup, ball, squeezing tray, blade, front cover and juicer tray washer. We must
verify when removing the front cover, and the squeezer tray that the error and the STOP prompt appears on the screen.
1.2.1 Check the status of the tray filter and that the screw of the squeezer tray by unscrewing the ball from it.
1.2.2 Check if we have the Allen key (V0070) on the
machine base to unblock the machine manually.
1.3. - Check the status of the feeder and the top of the machine.

1.4. - Check power input plug, cable, and fuse holder (Verify if there is one 6A fuse in backup and that the fuse in the
machine is not wasted).
1.5. - Note the cycles counter reading. The number of cycles will be written to count the number of cycles made since
the last revision. To view them, the machine must be properly assembled then press the STOP button and the number
of cycles will appear on the screen.

2. - MACHINE DISMANTLING AND INTERNAL INSPECTION
2.1. - To open the machine, follow these steps:
Firstly, remove all external parts them being the basket, front cover, the squeezing tray (unscrewing the fastening nut)
and the bin. All these parts are mounted without any fixing accessories (besides the FN, no tool needed) but refer to the
first point of the technical instructions if necessary.
After this extract the three caps from the top of the machine with a small flat screwdriver or a cutter to access the
screws.
Use a long screwdriver (longer than 125mm) to unscrew the three screws that hold the top to the body of the machine.
Una vez estén completamente desenroscados los tres tornillos, levante el techo y colóquelo en la posición que
muestra la imagen. No es necesario desconectar las conexiones de la placa electrónica.

Loosen the front and back legs by unscrewing them.
Unscrew the two 3mm screw front supports and two from the four 4 hexagonal head screws (same type as before) that
fix the front to the bottom. Then take the front off.
Disconnect the cables from the electronic board and cut the cable tie. Following that, unscrew the other two back
inferior screws that were still there to extract the body.

2.2. - Check the cup and blade slide covers
To check if the cup slide shaft needs greasing, turn on the machine with everything mounted again (do this before 2.1
most preferably) and then take off only the upper protective part (1902010) just when the cup and the blade meet
exactly like the left down picture below.
Then unscrew the blade and take it off.
Introduce the fingers on the inside side of the cup, pull strongly to the left side, and release at once. The cup must come
to the initial position. Otherwise, the shaft needs to be greased. Go to 2.8.2 and follow the instructions given there.
2.3. - Verify both cup shaft, pinion, and bridge status
2.4. - Check the Allen screw that fixes bridge and the connecting rod

2.5. - Check the status of the ball bearing
2.6. - Check the motor/gearbox set status.
7. - Check blade shaft kit and ratchet slide status
When the blade spins instead of keeping still when cutting, we should look at the probe-slider mechanism because it
has probably misadjusted. Please check the following:
1. When the probe-slider is on the left, the probe may lay at least 2mm up the ratchet slide, as the picture
below shows. It must be checked that the corners have not been excessively worn which would be
preventing the ratchet slide to block the probe.

2.- Check that when the ratchet slide is set free (on the right of its movement), this one sets free the
movement of the probe without any obstruction.
If any of these two conditions is not met, we will proceed to solve it by changing the slider position acting on the slide
guide as shown below:
1. Loosen the screws on the ratchet slide guide.
2. Turn the ratchet slide guide inwards to make it tighter between the ratchet slide and probe or
outward to reduce the contact surface.
After setting the wanted tightness, screw back the screws that fix the slider guide in place.

2.8.1 - Internal cleaning and greasing.
To check if the blade shaft needs greasing, turn on the machine and stop with the main switch just when the cup and
blade are in the position in the left down picture below.
Taking care not to touch the metallic blade, pull strongly from the blade downwards and then release at once, as shown
in the right down picture below. The set should go back to the initial position. Otherwise, the shaft needs to be greased.
In case the blade does not come back quick we shall proceed to disassemble the machine as shown in the following
steps.
1. Take off the springs from the blade shaft.

2. Take off the c-clip and washer.
3. Take off ratchet slide pulling from it inwards the machine.
4. Loosen the blade shaft screw.
5. Pry the probe out with a flat screwdriver.

6. Take off the key from the shaft keyway.
7. Clean the shaft and grease it.
8. Clean the bearing and grease inside.
9. Assemble the shaft and mount it back on the machine.

2.7.- Cup slider and bridge greasing.
To check if the cup slider needs to be greased, turn on the machine and remove the upper protection when the cup
and blade will be show as displayed on the left picture below.
Loosen the blade nut and remove blade.
Inserting your fingers into the concave part of the cup, pull hard to the left and release it suddenly, as shown in the
figure below right. The cup should return strongly to its initial position. If not, the shaft needs lubrication. Then
proceed as follows:
1. Check that the connecting rod is in vertical position and that the cup is facing upwards (with the concave part
vertically looking up).

2. Loosen the screw that keeps the cup shaft pinion in its place.
3. Take off the pinion as well as the key to be able to extract the shaft.
4. Clean and grease the inner part of the shaft.
5. Clean and grease the inner part of the slide where the shaft rests.

6. Assemble the shaft again.
7. Put the key back in the keyway.
8. Place the pinion engaged as to make the cup facing upwards as described in 1.
9. Screw again using the washer 1095008 and the T-933-M8x20 screw.
2.9. - Front cleaning and greasing.

3. –CLOSING OF THE MACHINE AND OPERATION TEST
3.1. - Proceed to the re-assembling of the machine. All the exterior parts will be again mounted, and all security options
will be checked again. We recommend doing an operational test again to check the proper functioning.
