Commissioning; Securing - IKA RW 28 digital Betriebsanleitung

Assemble the overhead stirrer and all necessary
accessories on a stable, even, non-slip surface.
The RW 28 digital overhead stirrer must be se-
cured 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.
Securing extension arm to the overhead stirrer
Diagram (see Fig. 4)
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 hexagon socket screw as required.
Securing the stirrer to the stand
Diagram (see Fig. 5)
Attach the cross sleeve (H) to the upright of the
stand (I). Attach the extension arm (J) to the side
of the cross sleeve not in use, with the opening
facing upwards.
Tighten both clamping bolts (G) firmly once the
desired position for the stirring procedure has
been adjusted correctly.
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 a stirring element using the chuck
Diagram (see Fig. 6)
Slide the stirring tool (M) into the chuck (L). Tighten
the chuck firmly using the chuck key (K).
The stirring tool must only be changed when the
equipment is stationary and the power supply is dis-
connected.

Commissioning

Accessories must be assembled according to the
following assembly instructions (Fig. 4 to Fig. 8).

Securing

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 equipment. Use the bolts (U) to attach the
plastic half-shell pieces to the stirrer (T), as shown
in Fig. 7. The screw (S) can be used to adjust the
length of the stirring shaft protector.
Check that the stirring shaft protector is held in po-
sition securely prior to each use and also at regular
intervals. The position of the stirring shaft protec-
tor must only be adjusted when the equipment is
stationary 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 fac-
ing 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).
If above conditions are
met, the instrument is
ready for operation af-
ter plugging in the mains
plug.
