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
- The appliance is not running smoothly
- The container moves on the base plate
• Beware of hazards due to:
- Flammable materials
2

- Combustible media with a low boiling temperature
Incorrect container size
-Overfilling of media
- Unsafe condition of container.
• The appliance may overheat when in use.
• Process pathogenic materials only in closed vessels under a
suitable extractor hood. Please contact us 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 “Delivery Scope” 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 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.
