5.2.2 Bottom part
The bottom part comprises of a base plate to which is welded a cylinder of the crushing mechanism’s
working compartment. To the base plate bottom is attached a U-shaped stand. Into this stand is inserted a
plastic container in which the crushed material is collected. When crushing fruit, a bag is inserted in the
container (see Chapter 4.3.3). The container is during the crushing process secured by a handle to the body
of the crusher. This will prevent the container from moving due to the machine’s vibrations. When the
container is removed (by pulling it out forward), a flap automatically shuts the discharge gate, preventing the
operator from getting injured by putting a hand close to the crusher’s rotating parts. When the container is
replaced under the crusher, the flap opens again.
Please note: It is prohibited to open the flap while the crusher is running and put hands inside this
compartment or insert any objects in it! DANGER OF INJURY!
To the base place is attached by four screws a flanged electromotor, the shaft of which passes through a
packing ring to the centre of the crushing mechanism’s work compartment. The electromotor is protected
against the effects external environment by a welded sheet metal cover. The arrangement of other parts of
the machine’s bottom is shown in Fig. 2.
5.2.3 Work mechanism and power drive
The machine’s work mechanism is a rotating stainless steel disc, fitted on the front side with a single blade.
The disc is mounted on the electromotor shaft and secured by a central screw. The electromotor is attached
by sunk head screws to the crusher’s bottom part base plate. The work mechanism is powered by a flanged,
single-phase, asynchronous, short-circuit-armature electromotor with permanently connected capacitor.
Running direction of the motor cannot be changed without changing its internal winding, which guarantees
that the cutting disc will rotate in the correct direction. The design and arrangement of the machine’s working
mechanism is illustrated in Fig. 3.

machine’s electrical equipment is designed for connection to a single-phase, 1/PE+N ~230 V, 50 Hz power
supply. The machine is connected through a H05VV-F 3G1, 3 x 1 mm2power cord, with one end rigidly
connected to the machine and the other end fitted with a single-phase, 10/16 A plug. Using extension power
cords must comply with the requirements of ČSN 34 0350. The machine’s electromotor is switched on and
off by a switch, situated on the side of the electromotor cover. Protection against electrical shock is by
automatic disconnection from power supply in accordance with Sub-clause 413.1.3 of ČSN 33 2000-4-41.
WARNING! The machine does not have any protection against temporary power failure,
i.e. against power failure followed by restoration of power supply. In the event of power
failure, the machine operator must disconnect the machine from power supply by pulling
the power cord plug out of the power socket.
Before shipping, every machine undergoes in the manufacturing plant a final inspection pursuant to CBWS
Public Notice No. 48/1982 and ČSN 33 1500. Due to the simplicity of the machine’s electrical equipment, a
schematic wiring diagram is not included in this User’s Guide.
5.3.1 Safety devices
The electromotor power supply circuit has a safety end-switch which automatically disconnect the
electromotor power supply circuit when the top cover of the crusher, covering the machine’s work
mechanism, is removed. The safety micro-switch is controlled by one of the screws holding the top part (see
Fig. 1, Position 9).
6 Installing the machine
The machine is supplied assembled, with the power cord connected to the electromotor terminal box. The
machine is installed outside, near the place selected for processing and with adequate space to manipulate
the material to be processed. The machine must be placed on a firm and even ground to guarantee its
stability when running.
When manipulating the machine during installation, proceed as instructed in Chapter 12 of
this User’s Guide.
WARNING! Never put and run the machine outside when it rains, the machine’s electrical
equipment is not, due to the used level of protection by cover, resistant against undesirable
effects of water. Danger of electrical shock and damaging the machine.
Before installing the machine, power supply must be available for connecting the machine to power mains in
compliance with the instructions specified in Clause 6.1 of the se User’s Guide.

10
WARNING! Due to the fact that crushed material is handled in the vicinity of the crusher,
there is an increased danger of slipping and tripping in this area.
6.1 Connecting the machine to power supply
The crusher’s electrical equipment can be connected only to the corresponding single-phase, 230 V, 50 Hz
power socket with a protective contact connected to a protection wire. The circuit of the single-phase socket
for connecting the crusher to the power mains must be wired in accordance with the requirements of
regulations and technical standards applicable for the equipment of this type, in particular
ČSN 33 2130, Part 2.3, ČSN 33 2180, Part 6, ČSN 33 2000-4-41, ČSN 332000-5-51 Chapter 512, ČSN
332000-5-54 Chapter 543 and related regulations. The circuit must be at the point of connection protected
against excessive current by a fuse or circuit breaker of a maximum nominal value of 10 A, and due to the
environment and working conditions of the machine, must be equipped with a current protection device of a
maximum nominal tripping differential current In = 30 mA! This will provide the machine with an enhanced
protection against electric shock. If it is necessary to use an extension power cord to connect the crusher to
power mains, the extension power cord must be fitted with a plug and a socket of the same type and of the
same nominal current rating and the same nominal voltage rating and designed for the use in external
environment. The cross-section of the power cord’s wires must not be smaller than 1.5 mm2and 2.5 mm2for
extension power cords up to 25 m and 50 m long, respectively.
WARNING! Extension power cords longer than 25 m should be used only in exceptional
circumstances, and an increased care should be taken to protect them against mechanical
damage. Using extension cables longer that 50 m is not permitted, as reliable functioning of
the protection against electrical shock cannot be guaranteed.
Extension power cords must be laid in accordance with the requirements of ČSN 34 0350 Article 3509 and
Article 3510, guaranteeing their adequate protection against mechanical damage and making sure that they
are not in the way in the area through which they are running. As a protection against mechanical damage,
use mainly protection by correct positioning, i.e. run the power cord through places where it will not be
exposed to any danger of mechanical damage.
7 Putting the machine into operation
Before putting the machine into operation, the operator must evidently familiarise him/herself with basic
information about the machine, its functions, safety instructions as defined in Chapter 4 of this User’s Guide
and with the principles of maintenance specified in Chapter 9 of this User’s Guide. Before first starting the
machine, check whether all its parts are adequately mechanically attached and make sure that there are no
foreign objects in the work compartment. If no defect has been found, proceed to put the machine into
operation according to the following instructions.
Set the machine’s electrical drive switch into the position I “ON”.
Please note: You don’t have to check rotating direction of the electromotor. The electromotor is
factory-wired to drive the work mechanism in the correct direction.
After the crusher’s electromotor has reached full operating speed, you can start loading material into the
crusher.
Warning: When the crusher has stopped due to overloading, it is prohibited to take the
contents out of the work compartment by hand and put hands into the interior, unless the
machine is in standstill and its switched off state secured by turning off the switch and
pulling the power cord plug out of the power supply socket!
Warning: When working with the crusher, operators must wear personal protection aids: ear
protectors to protect their hearing organs.
WARNING!: Frequent overloading of the electromotor might lead to the generation of excessive
