1.6. Description of the machine
This gravity feed slicer is a manual food slicer. The carriage is moved backward and forward manually.
The blade is driven electrically with a 1-phase or 3-phase motor. This motor is maintenance-free and air-
cooled. By means of a special air circulation the warming up of the motor is very low, especially around the
blade.
The food product is pushed against the blade by its own weight (gravity).
The material used in the food zone corresponds to all requirements of food hygiene.
The complete machine body, the thickness plate, the blade guard and the carriage are made of stainless
steel. The blade is hard chromed.
All visible bearings as well as open sliding surfaces are lubricated only with lubricant suitable for food
zones.
For switching the machine on and off there is used a double red /green push button with integrated signal
lamp which is illuminated when the machine is switched on.
The red main button fulfils the requirements as emergency stop switch.
Self-starting of the machine after a voltage drop is avoided by the electric control.
The carriage can only be tilted aside when the thickness plate is closed completely. When the carriage is
tilted aside, the thickness plate is locked in this position.
The protecting and security equipment as well as electrical and mechanical components correspond to
regulations in force.
The machine is equipped with the following security equipment:
no self-starting of the machine after a voltage drop
double push-button
fixed ring around the blade, non-removable

5. Sharpening the blade
In case the cutting result should no longer be satisfactory or the food products are getting "beards", the
blade has to be sharpened. There cannot be indicated a certain period for sharpening as this depends on
the time of operation and the kind of food products.
Pay attention to the fact that the blade has to be exchanged if the gap between blade edge
and the fixed protecting ring is more than 5 mm. According to security regulations further
sharpening of the blade it is not allowed when the gap is more than 5 mm.
The supplied sharpening device is loosening its effect. A further sharpening is forbidden.
In case it is necessary to exchange the blade this has to be done by a service technician.
