If above conditions are
met, the instrument is
ready for operation after
plugging in the mains plug.
Securing the overhead stirrer to the stand
Diagram
(see Fig. 3)
Place RW 47 digital overhead stirrer on the arm of
the stand. Fasten the overhead stirrer to the stand
from below with hexagonal socket screws supplied.
The help of an assistant is needed for screwing on
the overhead stirrer. The cable clips included in the
delivery package are required for fixing the power
cable of the unit (see Fig. 6 and Fig. 7).
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 (I) into the chuck (H).
Tighten the chuck firmly using the chuck key (G).
The stirring tool must only be changed when the
equipment is stationary and the power supply is
disconnected.
Securing the stirring shaft protector
Diagram
(see Fig. 5)
You must use stirring shaft protector (K), e.g. R 301,
when working to prevent injury. Use the bolts (J) to
attach the plastic half-shell pieces to the stirrer (M),
as shown in Fig. 5. The screw (L) 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.
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).
Points of particular danger (such as crushing, rotat-
ing parts, clamping screws for stand legs and roll-
ers etc.) are marked in Fig. 8 with an exclamation
mark. Please pay particular attention to these danger
points during operation!
Securing
Securing the safety switch to R 472 floor stand
Diagram
There is a danger of trapping between the
safety limit switch, switch contacts and the
end stop!
Secure the safety switch SI 400 safety switch to
the support rod of R 472 floor stand via fixing de-
vice SI 472. For this, follow the assembly instruc-
tions for "Safety switch" in the Fig. 6.
Securing the safety switch to R 474 tele-
scopic stand
Diagram
There is a danger of trapping between the
safety limit switch, switch contacts and the
end stop!
Mount the safety switch SI 400 safety switch to
the support rod of R 474 telescopic stand via fix-
ing device SI 474. For this, follow the assembly
instructions for "Safety switch" in the Fig. 7.
Switching on the instrument
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 in-
strument only starts up once it has been set to the
designated working height and the switch contact
activates the safety switch.
