• 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.
