Safety Instructions - IKA T 65 D ULTRA-TURRAX Mode D'emploi

For your protection
• Read the operating instructions in full
before starting up and follow the safety
instructions.
• 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
medium to be processed. Otherwise there is a
risk of:
- spraying and vapourisation of liquids
- body parts, hair, clothing and jewellery get-
ting caught.
• The device must be wired by a qualified techni-
cian before first use in order to prevent risk of
electric shock!
• Use a safety cutout for height adjustable stands!
• Set up the stand in a spacious area on an even,
stable, clean, non-slip, dry and fireproof surface.
• 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 agitated vessels used for stirring have to
be secured. Consider on a good stability of the
entire structure.
• Secure the stirring vessel against twisting.
• Glass vessels must always be secured with a
clamp to prevent them spinning. When wor-
king in glass vessels, the dispersion tool must
not come into contact with 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.
• There may be electrostatic discharges between
the medium and the dispersing instrument
shaft which could pose a direct danger. In
some circumstances, the region between me-

dium and drive shaft, or between rotor and
stator, can become electrostatically charged,
and ignite an explosive atmosphere caused by
evaporation of the medium. In addition, with
advanced evaporation of the medium, the slide
ring seal can overheat to such an extent that
it would lead to an ignition or combustion of
the medium. For this reason, no inflammable or
combustible materials must be processed with
the dispersion unit.
• Rapid temperature change (thermal shock!) can
destroy the hard metal sealing surfaces.
• Check that the turning handles are secure and
tighten if necessary.
• If the emergency stop switch of the dispersion unit
is not within reach when the unit is operating, an
additional emergency stop switch must be ins-
talled within easy reach, in the working area.
• Before commissioning, the correct direction of
rotation of the motor must always be ensured
(test run without dispersion tool: motor rotati-
on as indicated on the arrow plate, or clockwise
rotation, looking down on motor). The wrong
direction of rotation can lead to the rotor or
stator coming off the shaft.
• If the unit is operated in different locations with
a 5-pin plug, the direction of rotation must be
checked before commissioning, with no disper-
sion tool fitted.
• 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.
• Ensure that the shaft of the dispersing instru-
ment is immersed in the medium to the appro-
priate depth for that instrument (see "Technical
Data") in order to prevent splashing.
®
• The distance between the dispersion tool and
the vessel bottom should not be less than
30 mm.
• 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!
• Please note that the dispersing element and the
journal bearings can become extremely hot du-
ring use.
