Safety instructions
•
Read the operating instructions in full before start-
ing 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 instrument.
• Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
• Because the options for combining products, tools, stir-
ring vessel, experiment and medium are nearly endless,
user safety cannot be ensured simply with design require-
ments on the part of the product. For this reason, it may
become necessary for users to take other precautionary
safety measures. For example, glass apparatus or other
stirring vessels that are sensitive to mechanical stress can
be damaged or shattered by an imbalance, increasing the
speed too quickly or too little distance between the stir-
ring element and the stirring vessel. Users can suffer seri-
ous injury from glass breakage or from the freely rotating
stirring element.
• Uncontrolled reactions can be triggered by mixing 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
protection). In any case, when using critical or hazard-
ous materials in your processes,
IKA
®
recommends to use
additional appropriate measures to ensure safety in the
experiment. For example, users can implement measures
that inhibit fire or explosions or comprehensive monitor-
ing 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 mains switch cannot ensure
this access at all times, an ad-
ditional
EMERGENCY STOP
switch that can be easily accessed must be installed in
the work area.
• Only process media that will not react dangerously to the
extra energy produced through processing. This also ap-
plies to any extra energy produced in other ways, e.g.
through light irradiation.
• Do not operate the instrument in explosive atmospheres,
with hazardous substances or under water.
• Process pathogenic materials only in closed vessels under a
suitable fume hood. Please contact
IKA
®
application support
if you have any question.
• The instrument is not suitable for manual operation.
• The high torque developed by the
RW 20 digital
re-
quires 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 securely
clamped in the chuck!
Remove the chuck key from
the chuck before turning on
the device.
• Use stirring shaft protective equipment!
• The agitated vessels used for stirring have to be secured.
Consider on a good stability of the entire structure.
Please pay attention to the dan-
gerous parts of the equipment in
Fig. 8
.
• Protect the instrument and accessories from bumping
and impacting.
• Check the instrument and accessories beforehand for
damage each time when you use them. Do not use dam-
aged components.
• Safe operation is only guaranteed with the accessories de-
scribed in the ”
Accessories
” section.
• Always switch the mains switch in the
OFF
position 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 correspond to
the mains voltage.
• Please observe the permitted speed for the stirring ele-
ment. Never set higher speed.
• Make certain that the unit is set at the lowest speed be-
fore commissioning; otherwise, the unit will begin run-
ning 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.
Never operate the instrument
with the stirrer tools rotating
freely. Ensure that parts of the
body, hair, jewelry or items of clothing cannot be trapped
by the rotating parts.
The operation of a free rotating
shaft end is dangerous. There-
fore, for safety reasons, only
insert through the stirring tool over the upper edge of
housing at standstill.
