Commissioning; Securing - IKA EUROSTAR 20 digital Mode D'emploi

Assemble the overhead stirrer and all necessary ac-
cessories on a stable, even, non-slip surface. The
EUROSTAR overhead stirrer must be secured to a
stable stand (e.g. R 2722 or R 2723) with a cross-
sleeve (e.g. R 270). 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.
Securing the extension arm to the overhead
stirrer
Diagram (see Fig. 2)
Ensure that the extension arm is fitted securely.
Vibration may cause the screw to become loose. It
is therefore necessary for safe use to occasionally
check that the extension arm is attached securely.
Tighten the hexangular bolt as 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 overhead
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 posi-
tion of the stirrer must only be adjusted when the
equipment is stationary and the power supply is dis-
connected.
Securing the stirring element using the chuck
Diagram (see Fig. 4)
Applies to EUROSTAR stirrers with chucks.
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 equipment is stationary and the power supply is
disconnected.
Securing a stirring element using the conical
attachment
Diagram (see Fig. 5)
Applies only to EUROSTAR 20 high speed digital
stirrers.
Slide the R 6000 precision shaft (P) into the
conical attachment on the output shaft (N).
Tighten the retaining nut (O) using a hook
spanner and a single open-end wrench.

Commissioning

Accessories must be assembled according to the
following assembly instructions (Fig. 2 to Fig. 7).

Securing

To fit the stirring element (R), hold the output
shaft/precision shaft stationary using a single
open-end wrench. The stirring element can be
tightened in place with a second single open-end
wrench, using the area on the stirring element
provided for this purpose.
Check that the stirring element is held in position
securely prior to each use and also at regular in-
tervals. The stirring element must only be changed
when the equipment is stationary and the power
supply is disconnected.
Securing the stirring shaft protector
Diagram
Use a stirring shaft protector (Q), e.g. R 301, to
provide protection against injury when working
with the instrument.
Use the bolts (U) to attach the plastic half-shell
pieces to the stirrer (T), as shown in Fig. 6. The
screw (S) can be used to adjust the length of the
stirring shaft protector.
Check that the stirring shaft protector is held in posi-
tion securely prior to each use and also at regular
intervals. The position of the stirring shaft protector
must only be adjusted when the equipment is sta-
tionary and the power supply is disconnected.
Securing the mixing vessel to the stand
Diagram
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, 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).
If above conditions are
met, the instrument is
ready for operation after
plugging in the mains plug.
