Safety instructions
• Make certain that the unit is set at the lowest
speed before commissioning; otherwise, the
unit will begin running at the speed last set.
Gradually increase the speed.
• Reduce the speed if the medium splashes out of
the vessel because the speed is too high.
• Before switching on the dispersing instrument
make sure that its shaft is immersed min. 45
mm in the medium to prevent the medium
from splashing out.
• The distance between the dispersion tool and
the vessel bottom should not be less than 10
mm (fig. 1).
• Ensure that the stand does not start to move.
• In the event of unbalance or unusual noises,
switch off the appliance immediately. Replace
the dispersing element. If there is no difference
after the change of the dispersing tool, return it
to the dealer or the manufacturer along with a
description of the fault.
• Do not touch rotating parts during operation.
• Caution: Burns hazard! When in operation,
the dispersing element and the coupling flange
can become hot.
• Do not cover the ventilation slots on the drive in
order to ensure adequate cooling of the drive.
• Do not process any flammable or combustible
materials.
• Process pathogenic materials only in closed
vessels under a suitable extractor hood. Please
contact IKA
® if you have any questions.
• Do not operate the appliance in explosive at-
mospheres, with hazardous substances or un-
der water.
• There may be electrostatic discharges between
the medium and the dispersing instrument
shaft which could pose a direct danger.
• Only process media that will not react dange-
rously to the extra energy produced through
processing. This also applies to any extra ener-
gy produced in other ways, e.g. through light
irradiation.
• Meter powder not too close to the flange. Pow-
der can be blown away by air turbulences of
the drive.
• Safe operation is only guaranteed with the ac-
cessories described in the ”Accessories” chapter.
• Always disconnect the plug before fitting ac-
cessories.
• The appliance can only be disconnected from
the mains supply by pulling out the mains plug
or the connector plug.
For your protection
• Read the operating instructions in full be-
fore starting up and follow the safety ins-
tructions.
• Keep the operating instructions in a place whe-
re they can be accessed by everyone.
• Ensure that only trained staff work with the ap-
pliance.
• Follow the safety instructions, guidelines, occu-
pational health and safety and accident preven-
tion regulations.
• 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
- body parts, hair, clothing and jewellery get-
ting caught.
• Set up the stand in a spacious area on an even,
stable, clean, non-slip, dry and fireproof sur-
face.
• Check the appliance and accessories before-
hand for damage each time you use them. Do
not use damaged components.
• The appliance is not suitable for manual ope-
ration.
• The agitation vessels used for dispersing have
to be secured. Consider on a good stability of
the entire structure.
• Secure the agitation vessel against twisting.
• Check that the turning knobs are secure and
tighten if necessary.
• Glass vessels must always be secured with a
clamp to prevent them spinning. When wor-
king with flasks elastic couplers must be used
to prevent fracture of the glass.
• Note the operating instructions of the disper-
sing tool and accessories.
• Only dispersing elements approved by IKA ®
may be used.
• Please observe the permitted speed for the dis-
persing element. Never set higher speeds.
• Do not use the appliance without a dispersing
element.
• Use the dispersing tool always inside the stirring
vessel.
• Never run dispersion tools dry, as the gasket
and bearings will be destroyed if the tools are
not cooled by the medium.
• Caution: Burns hazard! If a dispersing element
is not inserted into the drive flange as far as the
mark it can become extremely hot in operation
and thus suffer damage.
