1. – CHECKING IF CLEANING AND GREASING IS NEEDED.
•
With the cups in a vertical position, turn the machine over using the Allen key,
turning in a clockwise direction (reverse) (or manually in older machines) until the
cups are in the horizontal position. The machine can also be started and stopped
when the cups are rising (N.B. ensure that it is not when the cups are
descending).
1a
In this position move the cups upwards by hand and release them (Fig 1b). They
should return easily to their initial position, without needing to be assisted.
•
Move the blade shaft up and down. It should descend under its own weight.
•
Examine the feed paddle rod - it should be lightly greased. Apply a small quantity
of grease if necessary. (Fig. 1c)
2.- OPENING THE MACHINE.
•
Disconnect the appliance from the mains power supply.
•
Remove all the external parts (Fig. 2a).
•
Remove the bolts from the top and the feed paddle, and the four from the base.
•
Loosen the four mounts by 2 to 3mm.

Page 2: Replacing The Electronic Circuit Board
• Extract the front of the machine (Fig. 2b). • Extract the rear (Fig. 2c) • Disconnect the wires from the switch and the mains power supply (Fig. 2d) except the mains supply bridge (Fig. 2e) • Extract the electronic circuit board (2.5mm Allen key) (Fig. 2f) 3.- REPLACING THE ELECTRONIC CIRCUIT BOARD. - Page 3 4.- REPLACING THE PUSHER ASSEMBLY. • Extract the key from the blade shaft (Figs. 4a and 4b). • Dismantle the three runner covers in order to work safely. • Extract the top bolt from the bridge (M8x50 Allen) and the top pin (Fig. 4c). •...
- Page 4 • Unscrew the bottom nut from the puller. An open-ended wrench will be required (Figs 6e and 6f). • Extract the runner with its spring and puller (Fig. 6g). ASSEMBLY • Screw the nut onto the puller, fit the washer and screw the puller onto the runner. There should be 210 -211mm free after the nut (Figs.
- Page 5 • Fit the runner onto the guide and then fit into position, in this order: 1st Rubber washer. 2nd Flat washer. 3rd Locknut. (Fig. 6ñ) • Complete the adjustment by adjusting the runner to 33.4mm using the nut on the bottom brake (Fig.
- Page 6 • Turn the motor by hand and fit the rod and the cups in position (Figs. 6v and 6w) • Raise the cups by hand to the vertical position and release them (Fig. 6x) in order to check if the runners work smoothly or stiffly. If they are excessively slack and there is play visible between the cogs and the bridge, the guides should be closed using a clamp (Fig 6y).
- Page 7 • Loosen the reducer bolts (Figs.) 7d – 7e – 7f) • Release the top pin (Fig. 7g) • Move the reducer backwards and loosen the bottom pin bolt (Fig. 7h) • Extract the pin (Fig. 7i) and renew the rod. ASSEMBLY •...
- Page 8 8.- REPLACING A REDUCER. • Remove the bolt from the rear of the reducer (Fig 8a). • Remove the bolts from the base of the reducer. • Move the reducer backwards to leave the shaft hanging (Fig. 8b). 9.- CHANGING THE MOTOR OR THE BELT. •...
- Page 9 10.- SETTING THE CUP STOPPING POSITION. • Only if the cups fail to stop in the vertical position. • Start up the motor, stop it with Stop and check if the cups stop before or after reaching the vertical position. •...
- Page 10 o It can also be solved by positioning a rubber stop at the top of the bridge runner. To do so, clean the top surface with solvent, and use adhesive to stick on the “RUBBER STOP” Ref. 0504024 (Figs. 10c – 10 d – 10e). 11.- BELT CHANGING (MACHINES WITH SHOCK ABSORBERS ON THE MOTOR MOUNT).

Page 11: Closing The Machine
2.- CLOSING THE MACHINE. • Grease the inside of the front on the areas rubbing against the runner covers, as in Fig. 12e. • Fit the front, checking that the cup shafts are centered with its holes. • Fit the short micrometer and check that each microswitch is activated before the micrometer catch finishes latching, as shown Figures 12b and 12 c. -
