The Zummo Z14 machine may be making a loud, weird noise due to loose or broken bands, loose cup nuts, or loose balls. Checking and tightening these components may help resolve the issue.

    2.- CHANGING THE BRIDGE Extract the top bolt from the bridge. (Fig. 6) Extract the top pin with the aid of a screwdriver. (Fig. 7) Extract the pusher assembly. (Fig. 6) Extract the bottom bolt from the bridge, thereby releasing it. Fit the new bridge and secure it with the bottom bolt.

    • In the event of there being play (greater than 0.2mm) between the cup runner and the bars guiding it, this play needs to be reduced. To do so, loosen the top chassis bolt corresponding to the outer bar of this runner, lower the runners as in Photo 8 and retighten the bolt but with the bar held closed with the aid of a clamp.

  • Page 6: Puller Runner Bolts

    4. - PULLER RUNNER BOLTS These bolts were originally of a “countersunk Allen” type and did not allow adequate tightening. They were factory fitted from machine No. 2067126 onwards. If this is the case, they should be changed for hexagonal head bolts (Fig.

    5.- TRAY SHAFT SUPPLEMENTS The machines were not originally fitted with these parts, which were incorporated from No. 2116011 onwards. These parts (reference Nos. 1405017 and 1405018) are to prevent the juice entering through the cup runner covers from reaching the central guides. If your machine does not have these parts, they should be fitted.

    7.- REPLACING A CUP RUNNER Remove the chassis closing device and extract the runner with its rod. The rod has to be released from the two bottom bolts. Fit the rod into the new runner and refit it into the chassis. Fit the chassis closing device and adjust the top position of the bars so that the runners have the minimum play without dragging.

    8.- ADJUSTING THE POSITION OF THE CUPS Move the cups to the vertical position. The runners should be touching the top end stops. (Fig. 20) Turn the reducer pulley anticlockwise and observe how the sectors of the copier move towards the bottom bearing. (Fig. 21) The bearing needs to be raised or lowered by adjusting the bottom nuts on the pullers (Fig.

    9.- REPLACING A REDUCER, A COPIER OR A ROD In these three cases the reducer needs to be released from its position, however, the most important point is that when refitting the reducer, the center of the reducer must be aligned perfectly with the center of the chassis. To do so, use a 12Ø...

    10.- ADDING A “CUP RUNNER BRIDGE” This part is designed to prevent the cogs from being able to come away from the toothed area of the bridge . This part was factory fitted from machine No. 2117054 onwards. If you need to carry out work on any machine not having this part, it should be fitted.
  • Page 12 Fit the screws (Fig. 32). They must not be over-tightened. See the final result, Photos 33, 34 and 35. To check proper functioning: Turn the reducer pulley clockwise until the cups are horizontal. Turn the cups by hand to the vertical position and release them (Fig. 36). On releasing them, the runners should reach the top end stop under the action of the springs, without manual assistance.
