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 in-
strument.
• Follow the safety instructions, guidelines, occu-
pational health and safety and accident preven-
tion regulations.
• Because the options for combining products,
tools, stirring vessel, experiment and medium
are nearly endless, user safety cannot be en-
sured simply with design requirements on the
part of the product. For this reason, it may
become necessary for users to take other pre-
cautionary safety measures. For example, glass
device or other stirring vessels that are sensitive
to mechanical stress can be damaged or shat-
tered by an imbalance, increasing the speed too
quickly or too little distance between the stirring
element and the stirring vessel. Users can suffer
serious injury from glass breakage or from the
freely rotating stirring element.
• Uncontrolled reactions can be triggered by mix-
ing 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
hazardous materials in your processes, IKA®
recommends to use additional appropriate
measures to ensure safety in the experiment.
For example, users can implement measures
that inhibit fire or explosions or comprehen-
sive monitoring equipment. Furthermore, us-
ers must make sure that the OFF switch of the
IKA®product can be accessed immediately, di-
rectly and without risk at any time.
If installation or positioning
cannot ensure this access at
all times, an additional EMER-
GENCY STOP switch that can
be easily accessed must be in-
stalled in the work area.
• Only process media that will not react danger-
ously to the extra energy produced through
processing. This also applies to any extra energy
produced in other ways, e.g. through light ir-
radiation.
• Do not operate the instrument in explosive at-
mospheres, 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 hand-held op-
eration.
• 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 se-
curely clamped in the chuck!
• Use stirring shaft protective equipment!
• The agitated vessels used for stirring have to be
secured. Consider on a good stability of the en-
tire structure.
Please pay attention to
the dangerous parts of the
equipment in Fig. 8.
• Protect the instrument and accessories from
bumping and impacting.
• Check the instrument and accessories before-
hand for damage each time when you use
them. Do not use damaged components.
• Safe operation is only guaranteed with the acces-
sories described in the ”Accessories” section.
• Always switch the main switch in the OFF posi-
tion or disconnect 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 cor-
respond to the mains voltage.
• Please observe the permitted speed for the stir-
ring element. Never set higher speed.
• 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.
• 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 rotat-
ing freely. Ensure that parts
of the body, hair, jewelry or
items of clothing cannot be
trapped by the rotating parts.

• 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 mi-
nor, invisible damage 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 particular the stirring tools can lead to un-
controlled resonant vibrational behavior of the
instrument and the whole assembly. Glass ap-
paratus 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.
• If the instrument is operated too long in over-
load 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 be-
fore opening. Live parts inside the instrument
may still be live for some time after unplugging
from the power supply.
Covering or parts that are ca-
pable of being removed from
the unit without accessory
equipment have to be reat-
tached to the unit for safe
operation in order to pre-
vent, for example, the ingress
of fluids, foreign matter, etc..
The operation of a free rotat-
ing shaft end is dangerous.
Therefore, for safety rea-
son, only insert through the
stirring tool over the upper
edge of housing at standstill.
Wear your personal protec-
tive equipment in accor-
dance with the hazard cat-
egory of the medium 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 run-
ning 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 medium and the output shaft which
could cause a direct danger.
• After an interruption in the power supply or a
mechanical interruption during a stirring pro-
cess, the unit does not restart automatically.

operation. The motor current is limited electroni-
cally. The instrument has an anti-stall and anti-
overload system.
If a fault occurs, a safety circuit immediately
switches off the motor permanently through a re-
lay in the power board. A fault occurs if the safe
functioning of the instrument is compromised.

• Use
For mixing/stirring liquids with low to high vis-
cosities by various stirring tools.
Intended use: Stand device (chuck points down)
• Range of use (indoor use only)
- Laboratories - Schools
- Pharmacies - Universities
This instrument is suitable for use in all areas except:
- Residential areas
- Areas that are connected directly to a low-voltage
supply network that also supplies residential areas.
The safety of the user cannot be guaranteed:
- If the instrument is operated with accessories that
are not supplied or recommended by the manu-
facturer
- If the instrument is operated improperly or con-
trary to the manufacture’s specifications
- if the instrument or the printed circuit board are
modified by third parties.

Speed – normal operation
Speed - regulated (no variation in speed)
The speed is monitored and regulated by proces-
sor controlled. The target speed is constantly com-
pared with the actual rotation speed value of the
output shaft and variations corrected. This guar-
antees a constant speed even if the viscosity of
the substance being stirred changes.
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 viscosity), the actual
speed is reduced until the stirrer torque corresponds
to the nominal torque of the machine, and the tar-
get 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 overload, the speed
is reduced 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).
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 (B, see
Fig. 1). During 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).
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 tem-
perature 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 stirrer shaft will go down
quickly to stop.
Display symbol: Er 4 (see section “Error codes“).
Output shaft
EUROSTAR 20/40/60/100 digital
The clamping chuck and output shaft permit clamp-
ing IKA® recommend stirrer tools (see section “Per-
mitted IKA® Stirrer tools“). The output shaft is
de signed 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 instrument.
EUROSTAR 20 high speed digital
The output shaft has cone seat specially for preci-
sion shaft. Stirring elements can be screw-connect-
ed on the precision shaft (see Fig. 5).
Please see section “Safety
instructions“!
The rotation speed is adjusted with the rotary knob
(B , see Fig. 1 ) on the front of the overhead stirrer.
Speed display
The rotational speed is displayed directly in revolu-
tions per minute (rpm) on the display (C, see Fig. 1).

provide protection against injury when working
with the instrument.
Use the bolts (U) to attach the plastic half-shell
pieces to the stirrer (T), as shown in Fig. 6. The
screw (S) can be used to adjust the length of the
stirring shaft protector.
Check that the stirring shaft protector is held in posi-
tion securely prior to each use and also at regular
intervals. The position of the stirring shaft protector
must only be adjusted when the equipment is sta-
tionary and the power supply is disconnected.
Securing the mixing vessel to the stand
Diagram (see Fig. 7)
First fix the cross sleeve (H) to the stand (I).
Then attach the bracket (Z) of the strap clamp in
the open side of the cross sleeve which is facing
upwards according to the position of stirrer and
the mixing vessel, firmly tighten the two clamping
bolts (G).

band (W) and secure the flexible band (W) by means
of the clamping lever (X).
Commissioning
Assemble the overhead stirrer and all necessary ac-
cessories on a stable, even, non-slip surface. The
EUROSTAR overhead stirrer must be secured to a
stable stand (e.g. R 2722 or R 2723) with a cross-
sleeve (e.g. R 270). The stirring vessel must always
be securely fixed for safety reasons. You must also
ensure that the mounting device (stand) is set up in
such a way that it is not liable to topple and does
not start to move during the stirring procedure.
