Safety Instructions - IKA T 65 digital 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 where they can be ac-
cessed by everyone.
• Ensure that only trained staff work with the device.
• Follow the safety instructions, guidelines, occupational health and
safety and accident prevention 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 vaporization of liquids
- body parts, hair, clothing and jewellery getting caught.
• The device must be wired by a qualified technician before first use
in order to prevent risk of electric shock!
• Use a safety cutout for height adjustable stands!
• If the unit cannot safely switched off during operation, an addi-
tional easily accessible EMERGENCY STOP switch must be installed
in the working area.
• Set up the stand in a spacious area on an even, stable, clean, non-
slip, dry and fireproof surface.
• Check the device and accessories beforehand for damage each
time you use them. Do not use damaged components.
• The device is not suitable for hand-hold operation.
• The vessels used for dispersing have to be secured. Consider on a
good stability of the entire structure.
• Secure the dispersing vessel against twisting.
• Glass vessels must always be secured with a clamp to prevent
them spinning. When working in glass vessels, the dispersion tool
must not come into contact with the glass.
• Note the operating instructions of the dispersing tool and ac-
cessories.
• Only dispersing elements approved by IKA may be used.
• Do not use the device without a dispersing element.
• Use the dispersing tool always inside the 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 medium and drive
shaft, or between rotor and stator, can become electrostatically
charged, and ignite an explosive atmosphere caused by evapora-
tion 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 of the dispersing tool S 65-KG HH.
• Check that the turning handles are secure and tighten if necessary.
• Ensure that the shaft of the disperser element is immersed in the
medium to the appropriate depth for that instrument (see manual
of the dispersing tool, chapter "Technical Data") in order to pre-
vent 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 de-
vice 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.

Safety instructions

• If the interaction between the medium and dispersing element
makes a loud noise, be sure to wear your personal protective
equipment.
• Do not touch rotating parts during operation!
ATTENTION!
• Never cover the ventilation slots or cooling fins on the motor as
these are needed for cooling the drive system.
• Meter powder not too close to the motor. Powder can be blown
away by air turbulences of the drive.
• Abrasion of the dispersion equipment or the rotating accessories
can get into the medium you are working on.
• Process pathogenic materials only in closed vessels under a suitable
extractor hood. Please contact IKA if you have any questions.
• Do not operate the device in explosive atmospheres, with hazard-
ous substances or under water.
• Do not process any flammable or combustible materials.
• 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.
• Always disconnect the plug before fitting accessories.
• After an interruption in the power supply, or a mechanical interrup-
tion during a dispersing process, the unit does not automatically
re-start.

• Before commissioning, the correct direction of rotation of the mo-
tor must always be ensured (test run without dispersion tool: mo-
tor rotation 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 dispersion tool fitted.
• An EMERGENCY STOP switch must be installed on this unit.
• The device 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.

• When changing over the dispersing element, switch the unit off at
the main switch.
• 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. Gradually increase the speed.
• Reduce the speed if the medium splashes out of the vessel because
the speed is too high.
In operation and for a relatively long time afterwards the
dispersing element and bearing can be very hot. Wear
your personal protective equipment.
Pay attention to the following situation:
- Dispersing tools can become very hot during oper-
ation. Before changing tools or cleaning, make sure
that the tool has cooled down.
- If the shaft is mounted incorrectly, the outer tube of
the shaft can become very hot.
- The ball bearing in the upper part of the shaft tube can
produce heat and heat the outer tube very strongly.
- When processing hot samples, the shaft tube in the
upper part (outside of the medium) also becomes hot.
