Commissioning
For correct use, the stirrer machine must be fixed with a cross
sleeve (eg R181) to a stable stand (eg R1822). The stirrer contai-
ner should always be fixed with a tensioner (eg RH1) for safety
reasons.

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 (B) to the lowest
speed (left-hand position).In case of doubt, turn the speed knob
(C) to the lowest speed (all the way left) and set the gear train to
the lowest reduction stage.
The unit starts to operate when the rocker switch is pressed.
Note: The rocker switch (A) is not a mains power switch !

Output shaft

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
RW201095EU
effect on the function of the unit, and the knocking noise will
disappear after a short running-in period.
The chuck and off-drive shaft allow stirrer attachments with shank
diameters of up to 10mm to be clamped and inserted (except
RW20DZM.n P4). 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. Only use water with a detergent additive containing a
surfactant for cleaning, or for heavier soiling isopropylalcohol.
When cleaning the unit, take particular care not to bring
substances containing oil or grease into contact with the running
surfaces of the cone pulley and the friction wheel. This would
substantially reduce the frictional coefficient resulting from the
pairing of the friction wheel and cone pulley materials, and would
impair power transmission in the unit.
