Switching on the machine

Check whether the voltage given on the type plate corresponds
to the available mains voltage. The socket used must be earthed
(fitted with earth contact). If these conditions have been met, the
machine is ready to operate when the mains plug is plugged in.
If these conditions are not met, safe operation is not guaranteed
and the machine could be damaged.
During commissioning of the machine the output shaft starts to
run at the last speed set. Therefore check the setting of the con-
trol knob. Also ensure that the speed set is suitable for the test
texture selected. If in doubt, set the speed knob to the lowest
speed (left-hand position). In case of doubt use the rotary button
to set the lowest speed (front motor slide stop) and set the drive
at the lowest speed.
The unit starts to operate when the rocker switch is pressed.
If the unit has not been used for some time, a knocking noise will
be heard when switching on, which is due to the preload on the
friction lining of the friction wheel drive. This has no detrimental
effect on the function of the unit, and the knocking noise will
disappear after a short running-in period.

Output shaft

The chuck and off-drive shaft allow stirrer attachments with shank
diameters of up to 10mm to be clamped and inserted. The opening
at the top of the housing allows stirrer attachments to be pushed
up above the top edge of the housing, e.g. in order to change the
stirring bowl with the unit switched off.

Maintenance and cleaning

The stirrer is maintenance-free. It is subject only to the natural
wear and tear of components and their statistical failure rate.
When ordering spare parts, please give the manufacturing
number shown on the type plate, the machine type and the
name of the spare part.
Please send in equipment for repair only after it has been cleaned
and is free from any materials which may constitute a health
hazard. Use only cleansing agents which have been approved by IKA
to clean IKA devices. To remove use:
Dyes isopropyl alcohol
Construction materials water containing tenside / isopropyl alcohol
Cosmetics water containing tenside / isopropyl alcohol
Foodstuffs water containing tenside
Fuels water containing tenside
For materials which are not listed, please request information from
IKA. Wear the proper protective gloves during cleaning of the devices.
Electrical devices may not be placed in the cleansing agent for the
purpose of cleaning.
When cleaning the unit, take particular care not to bring sub-
stances containing oil or grease into contact with the running sur-
faces of the cone pulley and the friction wheel. This would sub-
stantially reduce the frictional coefficient resulting from the pairing
of the friction wheel and cone pulley materials, and would impair
power transmission in the unit.
Make certain that the hexagon head nut (part no. 11 of spare parts
diagram) is sufficiently tightened in order to prevent the shifting of
the motor plate and thus the speed as well.
