secured to a stable stand with four screws (e.g.
R 474 or R 472 ) and wired according to the wi-
ring plan for proper use. The stirring bowl must
always be well secured for safety reasons.
You must also ensure that the mounting equip-
ment (e.g. floor stand, telescope stand) is set up
in such a way that it is not liable to topple and
does not start to move during the stirring proce-
dure. Accessories must be assembled and wired
according to the assembly instructions.
Check whether the voltage given on the type
plate corresponds to the available mains volta-
ge. 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.
When working with safety switch SI 400, the ap-
pliance only starts up once it has been set to the
designated working height and the switch con-
tact activates the safety switch.
During commissioning of the machine the output
shaft starts to run at the last speed set. Therefore
check the setting of the control knob (speed).

stopped). Otherwise this may cause damage to
the gear cogs. The arrow on the front plate indi-
cates the direction of the chuck.
If the stirring unit is operated in such a way that
the appliance's EMERGENCY OFF switch (B) (Fig.
2) is not accessible, you must add an another
EMERGENCY OFF switch to the work area so that
it can be easily reached.
Points of particular danger (such as crushing, ro-
tating parts, clamping screws for stand legs and
rollers etc.) are marked in Fig. 3 with an exclama-
tion mark. Please pay particular attention to these
danger points during operation!
Also ensure that the speed set is suitable for the
test texture selected. If you are unsure, set the

The appliance will start up when you press the
ON switch on the motor (Fig. 2).
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 de-
trimental effect on the function of the unit, and
the knocking noise will disappear after a short
running-in period.
