Accessories must be assembled according to the following
assembly instructions (
Fig. 2
to
Fig. 6
).
If above conditions are met, the in-
strument is ready for operation after
plugging in the mains plug.

section). The output shaft is designed as a hollow shaft, and
the opening on the top side of the housing is closed with a
stirrer cover. When open the stirrer cover, it is possible for stir-
ring shafts to push out over the top edge of the housing at
standstill
, e.g. during change container.
For safety reason, the the plastic cover must be pushed back
into the opening of the housing so that this is properly closed.
This is the only way to ensure that working with the unit is
safe and that media cannot enter the instrument.
Please see section “Safety in-
structions“!
The rotation speed is adjusted with the rotary knob (
B
, see
Fig. 1
) on the front of the overhead stirrer.
The rotational speed is displayed directly in revolutions per minute (rpm) on the LED display (
C
, see
Fig. 1
).

Commissioning
Assemble the overhead stirrer and all necessary accessories
on a stable, even, non-slip surface. The
EUROSTAR 400
digital
overhead stirrer must be secured to a stable stand
(e.g.
R 2722
or
R 2723
) with a cross-sleeve (e.g.
R 271
).
The stirring vessel must always be securely fixed for safety
reasons. You must also ensure that the mounting device
(stand) is set up in such a way that it is not liable to topple
and does not start to move during the stirring procedure.
NOTICE
Securing
Securing the extension arm to the overhead stirrer
Diagram
(see Fig. 2)
Ensure that the extension is fitted securely.
Vibration may cause the screw to become loose. It is there-
fore necessary for safe use to occasionally check that the
extension arm is attached securely. Tighten the hexangular
bolt as if required.
Securing the overhead stirrer to the stand
Diagram
(see Fig. 3)
First secure the cross sleeve (
H
) to the stand (
I
). Then secure
the extension arm (
J
) of the stirrer in the open side of the
cross sleeve which is facing upwards. Once you have set the
position required for the stirring procedure, firmly tighten
the two clamping bolts (
G
).
Check that the stirrer is held in position firmly prior to each
use and also at regular intervals. The position of the stirrer
must only be adjusted when the equipment is stationary
and the power supply is disconnected.
Securing the stirring element using the chuck
Diagram
(see Fig. 4)
Slide the stirring element (
M
) into the chuck (
L
). Tighten the
chuck firmly using the chuck key (
K
).
The stirring element must only be changed when the equip-
ment is stationary and the power supply is disconnected.
Securing the stirring shaft protector
Diagram
(see Fig. 5)
Use a stirring shaft protector (
Q
), e.g.
R 301
, to provide
protection against injury when working with the instru-
ment.
Use the bolts (
U
) to attach the plastic half-shell pieces to the
stirrer (
T
), as shown in
Fig. 5
. The screw (
S
) can be used to
adjust the length of the stirring shaft protector.
Check that the stirring shaft protector is held in position
securely prior to each use and also at regular intervals. The
position of the stirring shaft protector must only be adjust-
ed when the equipment is stationary and the power supply
is disconnected.
Securing the mixing vessel to the stand
Diagram
(see Fig. 6)
First fix the cross sleeve (
H
) to the stand (
I
).
Then attach the bracket (
Z
) of the strap clamp in the open
side of the cross sleeve which is facing upwards according
to the position of stirrer and the mixing vessel (
V
), firmly
tighten the two clamping bolts (
G
).
Clamp the mixing vessel (
V
) with the flexible clamping band
(
W
) and secure the flexible band (
W
) by means of the clamping
lever (
X
).
