Safety Instructions
For your protection
• Read the operating instructions in full before
starting up and follow the safety instructions.
• Keep the operating instructions in a place where they
can be accessed by everyone.
• Ensure that only trained staff work with the appliance.
• Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
• Caution-Magnetism! Effects of the magnetic field have
to be taken in to account (e.g. data storage media,
cardiac pacemakers…).
• Wear your personal protective equipment in accordance
with the hazard category of the media to be processed.
Otherwise there is a risk from:
- Splashing and evaporation of liquids
- Ejection of parts
- Release of toxic or combustible gases
• Use only the AC adapter supplied
• Set up the appliance in a spacious area on an even,
stable, clean, non-slip, dry and fireproof surface.
• The base plate must be clean and intact.
• Check the appliance and accessories before hand for
damage each time you use them. Do not use damaged
components.
• Reduce the speed if
- The medium splashes out of the vessel because the
speed is too high
2

- The appliance is not running smoothly
- The container moves on the base plate
• Beware of hazards due to:
- Flammable materials
- Combustible media with a low boiling temperature
- Incorrect container size
- Overfilling of media
- Unsafe condition of container.
• The appliance may heat up when in use.
• Process pathogenic materials only in closed vessels
under a suitable extractor hood. Please contact 4E’s if
you have questions.
• Do not operate the appliance in explosive atmospheres,
with hazardous substances or under water.
• Only process media that will not react dangerously to
the extra energy produced through processing. This also
applies to any extra energy produced in other ways, e.g.
through light irradiation.
• Safe operation is only guaranteed with the accessories
described in the “Accessories” chapter.
• The centre of gravity of the assembly must lie within the
surface on which it is set up.
• The appliance must only be disconnected from the mains
supply by pulling out the plug-in power supply unit.
• Abrasion of the dispersion equipment or the rotating
accessories can get into the medium you are working on.
• When using the PTFE-coated magnetic bars, the
following has to be noted: chemical reactions of PTFE
occur in contact with molten or dissolved alkaline and
alkaline-earth metals, as well as with fine particle
powders of metals of the 2. and 3. group of the
3

periodical system at temperatures above 300-400°C .
Only elementary fluorine, chlorine trifluoride and alkaline
metals do attack PTFE, halogen hydrocarbons have a
reversible swelling effect.
To the protection of the equipment
Caution: Equipment may not be poured over with
aggressive media! Equipment never under water set!
• The voltage stated on the nameplate must correspond
to the mains voltage.
• Do not cover the device, even partially e.g. with metallic
plates or film. This results in overheating.
• Protect the appliance and accessories from bumps and
impacts.
• Ensure that the base plate is kept clean.
