- Page 43 3. Re-fitting components: After washing, re-fit all of the machine components as described below: Re-fitting the mixers Note: Regularly check the integrity of the gaskets and substitute them if they are broken, worn or swol- len. Only use original gaskets, made of food-safe rubber. The gaskets and their housings must be carefully lubricated before re-use.
- Page 44 Chapter 6 Washing – Carefully position the mixers (12) in the cylinders (13), rotating them so that the mixer shafts (20) are properly inserted in their housings on the bottom of the cylinders (13). Re-assembling the dispensing tap components Note: Regularly check the integrity of the gaskets and substitute them if they are broken, worn or swol- len.
- Page 45 Re-fitting the dispensing tap on the machine – Position the gaskets (6) in the tap housings (5). – Fit the tap body (5) on the 4 connecting rods and cross-tighten the clamping knobs (11). Reassembling the carburettor. – Position the gaskets (3) in the carburettor (2) hous- ings.
- Page 46 Chapter 6 Washing – Put a suitable container under the dispensing tap. – Press the “MIX” button and gradually lower all of the dispensing levers, in order to drain out the disinfect- ant solution. OPERATING THE MIXER FOR LONGER IS NOT HELPFUL AND IS HARMFUL. THE LACK OF LUBRICATION ,PROVIDED BY THE INGREDIENTS DURING PRODUCTION, COULD CAUSE WEAR ON THE MIXERS AND/OR THE CYLINDERS.
