For your safety
The SORVALL®centrifuges are manufactured accord-
ing to current technical standards and regulations.
Nonetheless, centrifuges may pose danger to individu-
als and surrounding if
• they are not used as designed
• they are operated by untrained personnel
• their design is improperly changed
• the safety instructions are not followed
Therefore, personnel involved with operation and
maintenance of the centrifuge must read and follow
the safety instructions.
In addition, the pertinent regulations for prevention of
accidents must be strictly followed.
This manual is an integral part of the centri-
fuge assembly and must be kept close at
hand at all times.
When damages to the power cord or at
casing are noticed the centrifuge must
to be set out of operation!
Proper use
The centrifuge is designed to separate liquid-
suspended materials having different densities and
particle size, respectively (maximum sample density is
1.2 g/cm³ {ml} at maximum speed).
Improper use
During a run, a safety zone of 30 cm around the centri-
fuge must be maintained where neither persons nor
hazardous materials may be present.
The centrifuge may cause harm to its user or other
persons or may damage goods if safety measures are
not followed:
Centrifuging hazardous materials
• The centrifuge is neither made inert, nor is it explo-
sion-proof. Therefore never use the centrifuge in an
explosion-prone environment.
• Do not centrifuge explosive or flammable sub-
stances. The same holds for substances prone to
react violently with each other.

For your safety
4
• Do not centrifuge toxic or radioactive substances or
pathogenic microorganisms without suitable safety
systems.
If microbiological samples of risk group II (according
to "Laboratory Bio-safety Manual" of WHO) are be-
ing centrifuged, aerosol-tight bio-seals have to be
used.
For materials in a higher risk group, more than one
precaution is required.
• Should toxins or pathogenic substances enter the
centrifuge or its parts, you must perform appropriate
procedures for disinfection (see "Maintenance and
care – Disinfection").
• Strongly corrosive substances that may cause
damage to materials and reduce the mechanical
strength of the rotor may be centrifuged only inside
protective tubes.
Handling the centrifuge
• Use only original accessories for the centrifuge. The
only exceptions are common glass or plastic centri-
fuge tubes if they are approved for the rotor speed
and RCF values.
• Never use the centrifuge unless the rotor is properly
installed.
• You may use the centrifuge only with a properly
loaded rotor. You must not overload the rotor.
• Strictly follow the rules and regulations for cleaning
and disinfection
• If the rotor or the rotor lid shows signs of corrosion
or wear, you must stop using it.
• Never open the lid manually if the rotor is still turn-
ing.
• You may use the emergency lid release only in
case of emergency, e.g. during an interruption of
power supply
(see chapter "Troubleshooting").
• Never use the centrifuge with an opened lid.
• Never use the centrifuge if the front panel has been
partially or totally removed.
• Changes in mechanical or electrical components of
the centrifuge may only be carried out by individuals
authorized by Kendro Laboratory Products.

For your safety

The Legend™ MACH 1.6 / R
The figure below shows a Legend™ MACH 1.6 R with
an opened lid and a swinging bucket rotor installed.
Description
The Legend™ MACH 1.6 / R is a general-purpose ta-
bletop centrifuge for biotechnological and pharmaceuti-
cal research that moves high capacity centrifugation
onto the fast track. It spins more tubes at higher RCFs
more rapidly than competitive instruments and can
process nominally 1.6 liters of sample in a single run.
There are various rotors with high RCF values that can
accommodate a wide range of accessories for all
common tube types, micro titer plates and deep-wells.
The user-friendly "QUIKset®" control panel permits
easy selection of speed, RCF value, run time and
deceleration profile, as well as temperature of the
Legend™ MACH 1.6 R. You can switch from speed to
RCF display and vice versa, with a touch of a button
and even during a run.

Description of the Legend™ MACH 1.6
8
Safety systems
The Legend™ MACH 1.6 / R is equipped with a num-
ber of safety systems:
• Housing and lid are constructed of 6 mm steel.
• Lid with window
• Lid lock with safety check
You can only open the centrifuge lid when the
power is turned on and the rotor has come to a
stop. You can only start the centrifuge if the lid is
properly locked.
• Automatic rotor identification
• Electronic unbalance detection as a function of rotor
(SMARTspinTM)
Do not tamper with the safety
systems!
Parts supplied
Accessories supplied with the centrifuge are:
− power cord
− a special wrench for securing the rotor
(As seen in the picture)
− condensed operating instructions
− corrosion protective oil
The printed documents consist of the delivery notes
and this Manual.

Before use
13
Before use
Centrifuge transport and installation
After opening the box remove the protective materials.
When transporting the centrifuge,
consider its weight (see "Technical
Data"); always grab it on both sides
ensuring that enough helpers are
around.
Do not lift on the front panel!
The centrifuge can be damaged by
jolting during the transport!
Transport the centrifuge only in the
upright position using proper con-
tainment and secure it properly.
Handle the centrifuge carefully.
Proper location
The centrifuge may only be used indoors. Its location
must meet the following criteria:
• A safety zone of at least 30 cm (12 inches) around
the centrifuge must be maintained. Hazardous ma-
terials must not be stored beside the centrifuge dur-
ing its use.
• The laboratory bench or centrifuge trolley must be
stable and resonance-free. A good support is pro-
vided by a laboratory bench or a centrifuge cart with
lockable casters.
• To ensure sufficient air circulation, a minimum dis-
tance from the wall of 10 cm (4 inches) at the back
and of 15 cm (6 inches) on each side must be kept.

Before use
14
• The centrifuge must be protected from heat and
direct sunlight.
• The location must be well ventilated at all times.
UV rays reduce the durability of
plastics.
Protect the centrifuge, rotors and
plastic accessories from direct
sunlight.
Main connection
Connect the centrifuge only to a grounded main power
supply. Make sure that the power cord is compatible
with the valid safety regulations and that your main
voltage and frequency correspond to the specifications
on the instrument label.
Make sure that the centrifuge is switched off (on the
right-hand side of front panel) before connecting
electrical wire to main power supply.

Rotors and accessories
A rotor is not included as part of a Legend™ centri-
fuge.
A large variety of rotors are available as accessories.
In addition, there are adapters and reduction sleeves
for a variety of commercially available tubes and
bottles.
For a complete list of available tubes, bottles, adapt-
ers and accessories, please refer to our current sales
documentation.

Legend™ MACH 1.6 (air cooled)
During centrifugation, heat is generated by air friction
between the rapidly spinning rotor and the air inside
the rotor chamber. The continuous air flow in the air
cooled centrifuge is restricting the temperature rise of
the samples. The equilibrium temperature rise de-
pends on the ambient temperature, the type of rotor,
the speed, the duration and the number of runs.
Use caution when touching rotors as
they may be hot after long runs at
high speed.
