The safety control prevents the motor from being switched on when the protection cap/mixing lid is not in
position and stops it if the protection cap/lid is raised during operation.
When the protection cap/lid is replaced, the speed control knob must be turned back to
"0" (reset function), before the motor can be restarted.
→Only the speed control knob can be used to turn the machine on and off
When the machine is overstressed or overheated, it switches off automatically.
If this occurs, after about 60 seconds, please press the black button
on the bottom plate of the motor base.
If you notice any irregularities or defects, please contact your
supplier. For more information see under "Repairs".
Never submerge or spray the engine block in water or other fluids! Do not clean with a water jet!
If necessary, only clean it with a damp cloth and be sure to unplug the machine first.
DANGER!
Thoroughly clean the machine after each use! Improper and careless cleaning can cause considerable health
risks from microorganisms.
The mixing attachments should not be cleaned while assembled in the dishwasher, they have to be
disassembled. The mixing attachments are to be thoroughly cleaned after each use or once a day.
Our mixing attachments are made from borosilicate glass and are therefore autoclavable. Borosilicate glass has
very good chemical and physical properties and is used for applications where in addition to the very good
chemical resistance, a very high heat resistance and thermal shock resistance and high mechanical strength are
required (e.g. round-bottomed flasks, beakers).
Upon heating of the flask no deformations are to be expected up to 400° C, however, they already occur at
lower temperatures due to the thermal expansion and the poor thermal conductivity of tensile and
compression stresses. If the permissible strength values are exceeded as a result to rapid heating or cooling
rates, fracturing occurs. Therefore - as with any glass - a maximum permissible temperature can not generally
be defined. If the flask is evenly and slowly heated up in the autoclave and then correspondingly cooled off,
then no problems should be expected for example at 135° C.
Never heat the flask on a hotplate and never expose it to abrupt temperature changes (e.g. don’t take it hot
out of the drying cabinet and put on a cold or wet lab table).
Just rinse and brush off if necessary. Never place in water or in the dishwasher, because otherwise the self-
lubricating bearings will wear out.
