Caution: Burns hazard!
If a dispersing element is not in-
serted into the drive flange as far as the mark it can become
extremely hot in operation and thus suffer damage.
So as to avoid unintentional ingress of air into the medium
due to excessively turbulent rotation, the whole unit can be
placed a little off center in the stirring vessel.
By using the turning knob (item 10) the speed may be in-
finitely varied to meet the requirements of the medium to be
processed.
The idle speed for the drive unit can be adjusted in the range
600 to 10000 rpm; the value will be shown on the LED display.
If these conditions are met the unit is
ready for service when the mains plug
has been plugged in.
The driving unit is switched on by means of the On/Off-
switch (item 9).
The speed is set by using the differently adjusting wheel.
The motor speed can be read off the LED display. For exam-
ple, a value of 8.6 corresponds to 8600 rpm.
The drive unit opens up a wide range of possibilities for dis-
persion technology in the conventional laboratory with a
respective performance output of approximately 700 watts
at 10000 rpm.
To ensure safe operation the driving unit is fastened to the tel-
escopic stand R 2723 (item 5) or the stand R 2722 by means
of a cross sleeve R 271(item 3).
In order to enhance the stability of the mechanical arrange-
ment, the driving unit has to be mounted as close as possi-
ble to the stand pillar.
The delivered extension arm is mounted as follows (over-
view fig. 1):
• Insert extension arm (item 1) into flange
• Screw in the cheese head screw (item 2)
• Firmly tighten cheese head screw (item 2) using the DIN 911
A/f 4 screwdriver
Vibrations may cause the cylinder head screw (item 2) to
loosen. Therefore, for your own safety, periodically check
that the extension arm is secure. If necessary, re-tighten the
cylinder head screw (item 2).

Working with the unit
Also pay attention to the ambient conditions listed in the
“Technical data”.
Assembling the dispersion tool:
(Overview Fig. 5)
- Open the knurled screw (item 3) so that the thread does
not protrude into the hole.
- Insert the dispersing element (item 2) from the bottom into
the drive unit (item 1) as far as the stop. The shaft will audi-
bly click into place when a small amount of force is applied
(sprung ball bearing) - depending on the type of disperser.
The dispersing element is fitted correctly if the dispersing
element is flush with the bottom edge of the drive unit.
-
Attention:
Now secure the dispersing element by screw-
ing the knurled screw tight (item 3).
