Safety instructions
• Read the operating instructions in full before starting
up and follow the safety instructions.
• Keep the operating instructions in a place where it can be
accessed by everyone.
• Ensure that only trained staff work with the instrument.
• Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
• Because the options for combining products, tools, stir-
ring vessel, experiment and medium are nearly endless,
user safety cannot be ensured simply with design require-
ments on the part of the product. For this reason, it may
become necessary for users to take other precautionary
safety measures. For example, glass device or other stir-
ring vessels that are sensitive to mechanical stress can be
damaged or shattered by an imbalance, increasing the
speed too quickly or too little distance between the stir-
ring element and the stirring vessel. Users can suffer seri-
ous injury from glass breakage or from the freely rotating
stirring element.
• Uncontrolled reactions can be triggered by mixing the
heated material insuciently or by the energy generated
by selecting a speed that is too high. In case of these
and other increased operational hazards, users must take
additional appropriate safety precautions (e.g. shatter
protection). In any case, when using critical or hazard-
ous materials in your processes, IKA®recommends to use
additional appropriate measures to ensure safety in the
experiment. For example, users can implement mea-
sures that inhibit fire or explosions or comprehensive
monitoring equipment. Furthermore, users must make
sure that the OFF switch of the IKA®product can be ac-
cessed immediately, directly and without risk at any time.
If mains switch cannot ensure
this access at all times, an ad-
ditional EMERGENCY STOP
switch that can be easily accessed must be installed in
the work area.
• Only process media that will not react dangerously to the
extra energy produced through processing. This also ap-
plies to any extra energy produced in other ways, e.g.
through light irradiation.
• Do not operate the instrument in explosive atmospheres,
with hazardous substances or under water.
• Process pathogenic materials only in closed vessels under a
suitable fume hood. Please contact IKA®application support
if you have any question.
• The instrument is not suitable for manual operation.
• The high torque developed by the EUROSTAR requires
particular care in the choice of stand, cross sleeve and
anti-rotation element for the agitating vessel.
• Set up the stand in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
• You must ensure that the stirring element is securely
clamped in the chuck!
Remove the chuck key from the
chuck before you switch on the
device.
• Use stirring shaft protective equipment!
• The agitated vessels used for stirring have to be secured.
Consider on a good stability of the entire structure.
Please pay attention to the dan-
gerous parts of the equipment
in Fig. 7.
• Protect the instrument and accessories from bumping
and impacting.
• Check the instrument and accessories beforehand for
damage each time when you use them. Do not use dam-
aged components.
• Safe operation is only guaranteed with the accessories de-
scribed in the ”Accessories” section.
• Always switch the main switch in the OFF position or dis-
connect the power before changing stirring element and
fitting allowed accessories.
• The instrument 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.
• Socket must be earthed (protective ground contact).
• The voltage stated on the type plate must correspond
to the mains voltage.
• Please observe the permitted speed for the stirring ele-
ment. Never set higher speed.
• Make certain that the unit is set at the lowest speed be-
fore commissioning; otherwise, the unit will begin run-
ning at the speed set in last operation. Gradually increase
the speed.
• Pay attention when setting the speed to any imbalance
of the stirrer tools and possible spraying of the medium
to be stirred.
Never operate the instrument
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.
The operation of a free rotating
shaft end is dangerous. There-
fore, for safety reason, only
insert through the stirring tool over the upper edge of
housing at standstill.

• It is important to note that the surfaces of the motor
(cooling fins) and certain parts of the bearing may get
very hot during operation.
• Never cover the ventilation slots or cooling fins on the
motor or on the instrument.
• Avoid knocking and impacting on the lower end of the
shaft and the chuck gear teeth. Even minor, invisible dam-
age can lead to imbalance and uneven shaft action.
• Ensure that the stand does not start to move.
• Imbalance of the output shaft, the chuck and in particu-
lar the stirring tools can lead to uncontrolled resonant
vibrational behavior of the instrument 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 im-
balance 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.
• If the instrument is operated too long in overload or if the
ambient temperature is too high, the instrument switches
off permanently.
• The machine must only be opened by trained specialists,
even during repair. The instrument must be unplugged
from the power supply before opening. Live parts inside
the instrument may still be live for some time after un-
plugging from the power supply.
Covering or parts that are ca-
pable of being removed from the
unit without accessory equip-
ment have to be reattached to the unit for safe operation
in order to prevent, for example, the ingress of fluids, for-
eign matter, etc..
Wear your personal protective
equipment in accordance with
the hazard category of the me-
dium to be processed, otherwise there is a risk of:
- splashing of liquids
- projectile parts
- body parts, hair, clothing and jewelry getting caught.
Beware of the risk of:
- flammable materials
- glass breakage as a result of mechanical shaking power.
Reduce the speed if:
- the medium splashes out of the vessel because the
speed is too high
- the instrument is not running smoothly
- the instrument begins to move around because of
dynamic forces
- an error occurs.
Do not touch rotating
parts during operation!
• There may be electrostatic activity between the me-
dium and the output shaft which could cause a direct
danger.
• After an interruption in the power supply or a mechanical
interruption during a stirring process, the unit does not
restart automatically.

Speed – overload operation
The stirrer can deliver double output for a short time to
even out load peaks which could occurs, for instance, if
solid or semi-pourable agents are added. If the operation is
in the overload range (e.g. process-related increase in vis-
cosity), the actual speed is reduced until the stirrer torque
corresponds to the nominal torque of the machine, and
the target speed blinks. The possible speed is continually
adapted to operating conditions, guaranteeing that speed
is as close as possible to the target speed set.
To protect the machine from overloading, the speed is re-
duced if the machine has been operated in overload mode.
The target speed set then does not correspond to the actual
speed of the output shaft. This condition is indicated by
blinking of the target speed (overload operation).
Overload status 1:
The machine is already running in the overload range, the
target speed does not yet correspond to the actual speed.
This condition is maintained as long as neither the motor
current nor the temperature exceeds the permitted limit
values.
Display symbol: blinking of the target speed.
When the load goes back to the normal range, the target
speed stop blinking and correspond to the actual speed.
Overload status 2:
When the machine meet a fluctuating load which is over
double of the nominal torque, the actual speed of the stir-
rer shaft will go down quickly to stop.
Display symbol: Er 4 (see section “Error codes“).
Drive
The speed can be adjusted continuously over two speed range (speed range I, speed range II ) with the knob (B, see Fig. 1).
Motor protection
The stirring instrument is suitable for continuous operation.
The motor current is limited electronically. The instrument
has an anti-stall and anti-overload system.
Speed – normal operation
Speed - regulated (no variation in speed):
The speed is monitored and regulated by processor con-
trolled. The target speed is constantly compared with the
actual rotation speed value of the output shaft and varia-
tions corrected. This guarantees a constant speed even if
the viscosity of the substance being stirred changes.
Fluctuations in mains voltage within the permitted toler-
ance range have no effect on the quality of regulation and
constancy of speed.
The speed is set using the front knob (B, see Fig. 1). Dur-
ing normal operations the speed value on the display (C,
see Fig. 1) corresponds to the speed of the output shaft in
revolutions per minute (rpm).
If a fault occurs, a safety circuit immediately switches off the
motor permanently through a relay in the power board. A
fault occurs if the safe functioning of the instrument is com-
promised.

Output shaft
The clamping chuck and output shaft permit clamping IKA®
recommend stirrer tools (see “Permitted IKA
®
Stirrer tools“
section). The output shaft is designed as a hollow shaft, and
the opening on the top side of the housing is closed with a
stirrer cover. When open the stirrer cover, it is possible for stir-
ring shafts to push out over the top edge of the housing at
standstill , e.g. during change container.
For safety reason, the the plastic cover must be pushed back
into the opening of the housing so that this is properly closed.
This is the only way to ensure that working with the unit is
safe and that media cannot enter the instrument.
Please see section “Safety in-
structions“!
The rotation speed is adjusted with the rotary knob (B, see Fig. 1) on the front of the overhead stirrer.
The rotational speed is displayed directly in revolutions per minute (rpm) on the LED display (C, see Fig. 1).
