Never operate the instru-
ment with the stirrer tools
rotating freely. Ensure that
parts of the body, hair, jew-
elry or items of clothing
cannot be trapped by the
rotating parts.
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
- malfunction.
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.
• 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 as these are needed for cooling
the drive system.
• 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 de-
vices 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
capable of being removed
from the unit without ac-
cessory equipment have
to be reattached to the
unit for safe operation in
order to prevent, for ex-
ample, the ingress of flu-
ids, foreign matter, etc..
The unit must be switched
off (motor standstill) be-
fore changing to another
gear speed, otherwise the
toothed gears in the reduc-
tion stage will be damaged.
The equipment must be
wired by a qualified techni-
cian, otherwise there is a risk
of electric shock!
• Before commissioning, the correct direction of
rotation of the motor must always be ensured
(test run without stirring tool: motor rotation as
indicated of the arrow on the front foil, clock-
wise rotation, looking down on motor). The
wrong direction of rotation can lead to the stir-
ring tool 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 each commissioning, with no
stirring tool fitted.
