Repair

In case of repair the device has to be cleaned and 

free from any materials which may constitute a 

health hazard.

For this use the "certificate of compliance" inclu-

ded or download the form from the  

IKA

®

 web-

site 

www.ika.com

.

If you require servicing, return the appliance in its 

original packaging.

Storage packaging is not sufficient. Please also 

use suitable transport packaging.

The drive unit is maintenance-free but not immu-

ne from wear. The motor brushes and the coup-

ling wear out over time.

Cleaning

For cleaning disconnect the 

main plug.

To clean the drive use only water with a detergent 

that contains tensides, or use isopropylalcohol for 

stubborn soiling (not for plastic parts).

Dispersion tools:

 Consider please the manuals 

associated to the dispersion tools.

- Do not allow moisture to get into the appliance 

when cleaning.

- Wear protective gloves when cleaning the de-

vices.

- Please consult with 

IKA

®

 before using any 

cleaning or decontamination methods, other 

than those recommended here. 

Working with the unit

Refer to the operating instructions for the filling 

level of the medium and the immersion depth 

into the dispersing element used.

Caution: Burns hazard!

 If a dispersing element 

is not inserted 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 centre in the 

stirring vessel.

By using the turning knob (pos. 10) the speed may 

be infinitely varied to meet the requirements of the 

medium to be processed.

The idle speed for the drive unit can be adjusted 

in the range 3 000 and 25 000 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 (pos. 9).

Also pay attention to the ambient conditions lis-

ted in the “Technical data”.

Assembling the dispersion tool

(Overview fig. 5)

- Open the knurled screw (pos. 3) so that the th-

read does not protrude into the hole.

- Insert the dispersing element (pos. 2) from 

the bottom into the drive unit (pos. 1) as far 

as the stop. The shaft will audibly click into 

place when a small amount of force is ap-

plied (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 screwing the knurled screw tight (pos. 3).
