• Use:

For mixing/stirring liquids with low to high viscosity by 
using various stirring tools. 

Intended use: Stand device (Chuck downward).

• Range of use (indoor use only):

- Laboratories   

- Schools

- Pharmacies   

- Universities

Correct use

This equipment 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 manufacturer 

- If the instrument is operated improperly or contrary to the 

manufacturer’s specifications 

- If the instrument or the printed circuit board are modified 

by third parties.

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 dy-

namic 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. 

• 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 capa-
ble of being removed from the 
unit without accessory equip-

ment have to be reattached to the unit for safe opera-
tion in order to prevent, for example, the ingress of fluids, 
foreign matter, etc.

.

The unit must be switched off 
(motor standstill) before changing 
to another gear speed, otherwise 

the toothed gears in the reduction stage will be damaged.
