• Even in the case of repair work, the unit must only be opened by
a qualified engineer. The mains plug must be pulled before ope-
ning the unit. The voltage-carrying components inside the unit
may continue to carry a voltage for some time after the mains
plug is pulled.
• With the hand enterprise and with the enterprise at the stand, it
is to be made certain that safe conditions, a suitable anti-twist
plate of the agitating container and a minimum distance of the
dispersion tool are ensured to the agitatingcontainer soil.
• Do not cover the ventilation slots on the drive in order to ensure
adequate cooling of the drive.
• The agitated vessels used for stirring have to be secured.
Consider on a good stability of the entire structure.
• Furthermore, the dispersing unit may only be used to stir those
materials or material mixtures that the user knows will not react
dangerously to the extra energy produced by the dispersing.
This also applies to extra energy by means of solar radiation
during the stirring procedure.
• Do not process any pathogenic materials in open vessels as this
may cause the user to inhale vapours. Always work under a sui-
table extractor hood, even when using closed vessels. Please
contact IKA customer services if you have any questions regar-
ding work with pathogenic materials or other materials which
require closed systems.
• Make certain that the unit is set at the lowest speed before com-
missioning; otherwise, the unit will begin running at the speed
last set. Dispersing at high speeds can cause the medium to
splash out of the mixing vessel.
• There may be dangerous electrostatic activity between the
medium and the dispersing tool.
• The appliance starts up again following a cut in the power supp-
ly. Please note that the appliance must be switched off at the
on/off switch in this case before the power supply is reconnec-
ted.
• The dispersing instrument may not be used in explosive rooms,
for mixing dangerous substances or under water.

• Please note that abrasion of the dispersion equipment or the
rotating accessories can get into the medium you are working
on. If there are any questions please contact IKA.
• Always disconnect the plug before changing dispersing ele-
ments and attaching accessories.
• The appliance can only be disconnected from the mains supply
by pulling out the mains plug or the connector plug. The socket
for the mains cord must be easily accessible..
• Meter powder not too close to the flange, otherwise powder can
be sucked into the drive.
• Never run dispersion tools dry, as the gasket and bearings will
be destroyed if the tools are not cooled by the medium.
• Never run dispersion tools dry, as the gasket and bearings will
be destroyed if the tools are not cooled by the medium.
• The gasket and bearings are made of PTFE and rustproof steel;
the following points should therefore be noted: Chemical
reactions of PTFE occur in contact with molten or solute alkali
metals and alkaline earth metals, as well as with fine powders of
metals in groups 2 and 3 of the periodic system at temperatures
above 300 °C - 400 °C. Only elementary fluorine, chlorotrifluoride
