AINTENANCE
The machine requires a very limited maintenance. Periodically, we suggest to:
- check the good conditions of the machine's parts;
- check that the electric power cable is not damaged;
- Try the efficiency of the safety devices (ref. Par. 8.2).
It is then useful to maintain the external panels clean and the surrounding area. Dust, paper fragments or other small objects
may penetrate in the machine through the ventilation loopholes (in particular if equipped with air condensation and rapidly
compromise its correct functioning.
The inside parts, to which the user MUST NOT accede, must be checked by the Assistance Service (ref. Par. 8. 3)
9.1 Maintenance during the disassembling of the parts
Check the integrity of gaskets (indicated with [G] in the figure) and substitute those that
are deteriorated.
Use exclusively original, compatible with food, rubber gaskets. The spare bag
contains a complete series of gaskets approved by the manufacturer.
To correctly replace the gaskets it is necessary to:
- remove the old gaskets by using a sharp tool, possibly non- metallic, paying attention not to scratch the seating of the
gaskets themselves;
- clean the seatings and the gaskets from any kind of grease before inserting the new gaskets.
A yearly preventive replacement of all wearing parts and all gaskets is recommended. We suggest you to always keep a
spare supply: to order it, make reference to the Spares Section contained in the Technical Handbook.
9.2 Checking of safety devices
Every three months, check that all safety devices on your machine are in perfect working order:
- if necessary stop the device by pressing the ON/OFF Pushbutton [K1]. Rotate the Main Breaker in “0” position. When
Main Breaker is correctly working, the POWER’s indicator [Z1] must be off.
- open the lid and remove the beater;
- check that protection grill [3] is intact and firmly fixed;
- close the lid and take the Main Breaker in “1” position;
- press the ON/OFF Pushbutton [K1] and, afterwards, the BEATING Pushbutton [K5] (the beater’s shaft will start). Then
open the lid. Provided that the lid’s magnetic contact is correctly working, the beater’s shaft will stop immediately and
the Display will show “oo” (two small squares).
If the machine’s functioning is as described, the safety devices are efficient.
T HE MACHINE MUST NOT BE USED IF ONE OR MORE OF THE SAFETY DEVICES SHOULD RESULT DAM -
AGED OR MALFUNCTIONING !
