Safety instructions 1312 Safety instructions
/// Device setup
Danger! ( )
Users must make sure that the OFF switch of the IKA device can be accessed
immediately, directly and without risk at any time. If installation or positioning
cannot ensure this access at all times, an additional EMERGENCY STOP
switch that can be easily accessed must be installed in the work area.
Warning! ( )
Ensure stable assembly. The vessel used for stirring must be secured.
Use stirring shaft protective equipment!
›Set up the stand in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
›Remove the chuck key from the chuck before turning
on the device.
› Place the power supply outside the working area of the device.
› Avoid knocking and impacting on the lower end of the shaft and
the chuck gear teeth. Even minor, invisible damage can lead to
imbalance and uneven shaft action.
› All screw connections must be properly tightened.
› The high torque developed by the device requires particular care
in the choice of stand, cross sleeve and anti-rotation element for
the agitating vessel.
/// Working with the device
Danger! ( )
Do not operate the device in explosive atmospheres, with hazardous
substances or under water. The device is not explosion – proof it does not
meet any Class / Division or Zone explosion protection standards.
› The device is not suitable for hand-held operation.
› Do not touch rotating parts during operation!
Warning! ( )
Pathogenic materials must only be processed in closed vessels under
a suitable fume hood. If you have any questions, please contact IKA
application support.
The operation of a free rotating shaft end is prohibited. Therefore, for
safety reason, only insert through the stirring tool over the upper edge
of housing at standstill.
Caution! ( )
Make certain that the unit is set at the lowest speed before commissioning;
otherwise, the unit will begin running at the speed set in last operation. Gradually
increase the speed. Please observe the max. permitted speed for the stirring
element. Never set higher speed.
Covers or parts that can be removed from the device without tools
must later be refitted to ensure safe operation. This will prevent the
infiltration of foreign objects, liquids and other contaminants.

Safety instructions 1514 Safety instructions
› Imbalance of the output shaft, the chuck and in particular the stirring
tools can lead to uncontrolled resonant vibrational behavior of the device
and the whole assembly. Glass apparatus and stirrer containers can be
damaged or shattered by this. It can cause injury to the operator, also can
damage the rotating stirring tool. In this case exchange the stirring tool
for one without imbalance or remedy the cause of the imbalance. If there
is still imbalance, return it to the dealer or the manufacturer along with a
description of the fault.
› There may be electrostatic activity between the medium and the output
shaft which could cause a direct danger.
› Never operate the device with the stirrer tools rotating freely. Ensure that
parts of the body, hair, jewelry or items of clothing cannot be trapped by
the rotating parts.
› Pay attention when setting the speed to any imbalance of the stirrer tools
and possible spraying of the medium to be stirred.
› Ensure that the stand does not start to move.
› 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.
Reduce the speed if:
› the medium splashes out of the vessel because the speed is too high,
› the device is not running smoothly,
› the device begins to move around because of dynamic forces,
› an error occurs.
/// Accessories
› Protect the device and accessories from bumping and impacting.
› Check the device and accessories beforehand for damage each time
when you use them. Do not use damaged components.
› Safe operation is only guaranteed with the accessories described
in the ”Accessories” section.
› Must disconnect the power before changing stirring element and
fitting allowed accessories.
/// Switch on / off the device
If the device is operated too long in overload or if the ambient
teperature is too high, the device switches off permanently.
› Disconnecting the device from the power outlet only works by removing
the main cord from the socket.
› The device must only be operated with the original power supply unit.
› The power supply comes with interchangeable plug adapters for different
countries so make sure the appropriate adapter is used.
› The outlet for the power supply must be easily accessible.
› After an interruption in the power supply during a stirring process,
the device does not restart automatically.
› The device must only be opened by trained technicians, even during repair.
The device must be unplugged from the power supply before opening. Live
parts inside the device may still be live for some time after
unplugging from the power supply.
/// Disposal
The device must be disposed of in accordance with national regulations.

Useful information
/// Stirrer
The stirring device is suitable for continuous operation. The motor current is
limited electronically. The device has an anti-stall and anti-overload system.
If a fault occurs, a safety circuit immediately switches off the motor
permanently. The device starts with the last settings made. If the device
vibrates too much, an error message appears on the display and an acoustic
signal sound (see chapter “Error codes”).
Speed
/// Speed – normal operation
Speed - regulated (no variation in speed):
The speed is monitored and regulated by processor controlled. The target
speed is constantly compared with the actual rotation speed value of the
output shaft and variations corrected. This guarantees a constant speed even
if the viscosity of the substance being stirred changes.
Fluctuations in mains voltage within the permitted tolerance range have no
effect on the quality of regulation and constancy of speed.
The speed is set using the front knob. During normal operations
the speed value on the display corresponds to the speed of the
output shaft in revolutions per minute (rpm).
/// Speed – overload operation
When solid or semi-viscous substances are added, the stirrer can be run for
a brief period at 130% its rated power. When running in the overload range
(for instance if the viscosity has increased at a particular stage of the process)
the speed will reduce to a degree sucient to keep the torque on the stirrer
shaft within the rated torque of the device.

Overload status 1
The device is already running within the overload range, however, the actual
speed does not match the set speed. This condition is maintained as long as
neither the motor current nor the device temperature exceeds their permissible
limit value. In this overload status the torque value flashes.
Overload status 2
The device stop at a load above 130 % of the nominal torque.
Message in the display (see “Error codes” section).
/// Output shaft
Caution! ( )
Please see section “Safety instructions“!
The clamping chuck and output shaft permit clamping IKA recommend stirrer
tools (see section “Permitted IKA Stirrer tools“). The output shaft is designed
as a hollow shaft and the opening on the top side of the housing is closed
with a plastic cover. When the stirrer cover is opened, it is possible for stirring
shaft to be pushed out over the top edge of the housing at standstill, e.g.
during changing container.
For safety reason, the stirrer cover must be pushed back into the opening of
the housing so that it is properly closed. This is the only way to ensure that
working with the unit is safe and that media cannot enter the device.
