Safety instructions
• Read the operating instructions in full before
starting up and follow the safety instructions.
• Keep the operating instructions in a place where
it can be accessed by everyone.
• Ensure that only trained staff work with the in-
strument.
• Follow the safety instructions, guidelines, occu-
pational health and safety and accident preven-
tion regulations.
• Because the options for combining products,
tools, stirring vessel, experiment and medium
are nearly endless, user safety cannot be en-
sured simply with design requirements on the
part of the product. For this reason, it may
become necessary for users to take other pre-
cautionary safety measures. For example, glass
devices or other stirring vessels that are sensitive
to mechanical stress can be damaged or shat-
tered by an imbalance, increasing the speed too
quickly or too little distance between the stirring
element and the stirring vessel. Users can suffer
serious injury from glass breakage or from the
freely rotating stirring element.
• Uncontrolled reactions can be triggered by mix-
ing the heated material insufficiently or by the
energy generated by selecting a speed that is
too high. In case of these and other increased
operational hazards, users must take additional
appropriate safety precautions (e.g. shatter pro-
tection). In any case, when using critical or haz-
ardous materials in your processes, IKA
® recom-
mends to use additional appropriate measures
to ensure safety in the experiment. For example,
users can implement measures that inhibit fire
or explosions or comprehensive monitoring
equipment. Furthermore, users must make sure
that the OFF switch of the IKA
® product can be
accessed immediately, directly and without risk
at any time, and above all, in case of fault.
If installation or positioning
cannot ensure this access
at all times, an additional
EMERGENCY STOP switch
that can be easily accessed
must be installed in the work
area.
• Only process media that will not react danger-
ously to the extra energy produced through
processing. This also applies to any extra energy
produced in other ways, e.g. through light ir-
radiation.
• Do not operate the instrument in explosive at-
mospheres, with hazardous substances or under
water.
• Process pathogenic materials only in closed ves-
sels under a suitable fume hood. Please contact
IKA
® application support if you have any ques-
tion.
• The instrument is not suitable for manual operation.
• The high torque developed by the RW 47 digital
requires particular care in the choice of stand, cross
sleeve and anti-rotation element for the agitating
vessel.
• Set up the stand in a spacious area on an even,
stable, clean, non-slip, dry and fireproof surface.
• You must ensure that the stirring element is se-
curely clamped in the chuck!
• Use stirring shaft protective equipment and a
safety cutout for height adjustable stands!
• The agitated vessels used for stirring have to be
secured. Consider on a good stability of the en-
tire structure.
Please pay attention to
the dangerous parts of the
equipment in Fig. 8.
• Protect the instrument and accessories from
bumping and impacting.
• Check the instrument and accessories before-
hand for damage each time when you use
them. Do not use damaged components.
• Safe operation is only guaranteed with the acces-
sories described in the ”Accessories” section.
• Always switch the main switch in the OFF posi-
tion or disconnect the power before changing
stirring element and fitting allowed accessories.
• The instrument can only be disconnected from
the mains supply by pulling out the mains plug
or the connector plug.
• The socket for the mains cord must be easily
accessible.
• Socket must be earthed (protective ground
contact).
• The voltage stated on the type plate must cor-
respond to the mains voltage.
• Please observe the permitted speed for the stir-
ring element. Never set higher speed.
• Make certain that the unit is set at the lowest
speed before commissioning; otherwise, the
unit will begin running at the speed set in last
operation. Gradually increase the speed.
• Pay attention when setting the speed to any
imbalance of the stirrer tools and possible
spraying of the medium to be stirred.
