Do not use abrasive detergents or products/creams for removing calcareous deposits. Do not
use solvents or diluents. Residual traces of these products can contaminate the foodstuffs
introduced into the machine. Do not use synthetic abrasives or metal wool, which might damage
the machine surfaces besides producing unsightly marks and scratching.
SECTION 5 - GENERAL MAINTENANCE
5.1 Maintenance
The machine is constructed very carefully and is fitted with high-quality components such as the
permanently lubricated roller bearings used in the transmission mechanism and motor and a
special transmission belt. These features will help to ensure excellent performance of the
machine with the guarantee of an operative life expectancy unequalled by any similar product.
Therefore, no maintenance procedure, lubrication or periodic adjustment must be carried out on
the machine.
5.2 Trouble-shooting
If you press the start button (A Fig.3) or 'pulse-operation' start button (B Fig.3) and the machine
does not run, proceed as follows:
1. Make sure that voltage is supplied to the mains circuit and see whether the socket switch is
turned to the ON (I) position.
2. Make sure the thermo-magnetic protector and the circuit interrupter have not been triggered
and that the controls are in the correct position.
3. Perform a simple test on both these devices by pressing the respective push-buttons.
4. Press the start button again on the machine.
If the machine still does not run, a maintenance technician must be consulted. The technician
will have to test the above devices again and check the condition of the fuse used to protect the
auxiliary circuit of the machine. The fuse is on the interface card installed inside the machine. If
you see the machine is not working properly, switch it off immediately and isolate it from the
mains circuit by pulling out the plug from the mains socket. Consult the authorised dealer, a
specialised technician or contact the manufacturer directly. The user must not tamper with the
machine.
Metcalfe Catering Equipment Ltd declines all responsibility, both present and future, with regard
to damage to persons or the environment which may derive from tampering with the machine
and in particular with the safety systems and devices by the user or by persons not expressly
authorised by us.
5.3 Storing the machine - What to do if the machine is not used for long periods
If the machine has to be left unused for long periods of time, it must be cleaned thoroughly.
Protect it from dust with a clean dry cloth. Do not cover the machine with plastic bags or sheets
of synthetic material as mould and condensation may develop under them.
5.4 Instructions for specialised installation operators
Detailed instructions regarding connection of the machine are given in other sections in this
manual.
The data indicated below is for specialised technicians, who may have to make a modification in
the original electric connection to vary the operation voltage from 415V to 240V and vice versa.
