DANGER! Electric shock hazard!
To avoid the hazard results please follow the safety instructions
below.
• Never allow the power cable to come into contact with heat
sources or sharp edges. The power cable should not hang over
the side of the working surface. Ensure that no one can step
on or trip over the cable.
• The power cable must not be folded, bent or tangled, and must
always remain fully unrolled. Never place the device or other
objects on the power cable.
• Do not lay the power cable over carpets or other inflammable
materials. Do not cover the cable. Keep away the cable from

order to avoid dangers.

- 31 -
•
The supply cable must be disconnected from the socket
only by pulling the plug.
• Never carry or lift the device by the supply cable.
• In any case do not open the device housing. In case of
electrical or mechanical modifications the electric shock hazard
will occur.
• Never immerse the device, the power cord and the power plug
in water or other liquids.
• Do not use any acid agents and make sure no water ingresses
the device.
• Never operate the device with moist hands or standing on wet
floor.
• Remove the plug from its socket:
- when the device is not used,

- before cleaning.
WARNING! Danger of injury!
To avoid the hazard results please follow the instructions below.
• Never touch rotating parts of the device during its operation.
• During the operation of the device, never place in the pot
any products or objects having properties other than those
foreseen for intended use, e.g. bones, frozen meat, non-food
products or other products such as e.g. scarves etc.
• Never use, hold or operate the device in the places other than
intended for its correct operation. Never operate the device with
one hand.
• During the operation of the device, never press the food
products or ingredients against the pot bottom, and generally
make sure other persons do not exert such pressure.

- 32 -
•
During the operation of the device do not put hands or other
body parts in the pot.
• Never immerse the device in the pot with the processed food
products deeper than the immersion mark.
• Never remove the device from the pot before its complete
stop and never earlier than 10 seconds from turning the
device off.
• Never remove safeguards and warning labels from the device,
either partially or fully.
• Never insert any objects inside ventilation holes of the device
body.
• Never place or lay the device on objects other than the wor-
king table, which must be fitted for food products and its height
from the floor must be within the range from 900 to 1100 mm.
• Never use flammable, corrosive or toxic cleaning agents

• Never use the device when all conditions ensuring
elimination of the residual risk are not fulfilled.
WARNING The residual risk results from removing
permanent covers and tampering with damaged / used parts!
• The operator absolutely must not attempt to open or
remove the permanent covers or protective elements.
• During completion, maintenance and cleaning and other
similar manual activities, connected with placing hands or
other body parts in the hazardous areas of the device, there is
the residual risk which may result in:
1. hitting the device parts;
2. abrasion and/or scratches due to contact with rough
device parts;
3. injuries inflicted by sharp parts;
4. cutting wounds due to contact with sharp parts,
5. entangling in moving parts (whip)
• Due to the need of placing hands in the vicinity of the knife during
cleaning or removing residues, there is a residual risk
consisting in the possibility of injuries with sharp objects.
• Therefore, the persons operating and performing maintenance
of the device must be trained in performing activities with
open covers and must be informed of resulting hazards, as
well as authorized by the responsible person.

Application and subassemblies
The device consists of the electric motor, placed in plastic casting (independent device
body). Equipment (beater, whisk) is fixed with use of retaining flange on the quick
coupling of device body with motor block and connected with the motor shaft by turning .
Place the desired food products in the container and start the device holding it in both
hands in appropriate places (see fig. on page 47) in a sequence as below:
1. put in the container or pot with attached equipment (beater or whisk);
2. start the device and do not turn it off until the product is prepared;
3. turn the device off and take it out of the container after ca. 10 seconds
and place it on an appropriate surface.
Properties of the device allow for the following processing of food products:
1. when the device touches the bottom of the container (with beater),
but do not exceed the immersion mark,
2. when the device operates in the air but being held with both
hands (with a whip).
The food product should be taken out of the container when the processing cycle is
completed and after taking out the device from the container.
All materials which have direct contact with food products are consistent with the valid
legal regulations about the hygiene of work with food products.
Depending on the needs, the device may be equipped with various additional
accessories (chapter 4.2 „Technical specification“).
