4.1 Closing the lid
After the rotor has been properly secured and loaded, close the
centrifuge lid, making sure that the interlock has been engaged.
4.2 Lid release
Following a run, the centrifuge will display will show flashing
“00”. This signals the end of a run and the lid can now be
opened by pressing the “lid knob” (left). Note that the lid can not
be opened until the display flashes “00” and the rotor has
stopped.
WARNING: Do not attempt to open the lid of any centri-
fuge until the rotor has come to a complete stop.
In the event of a power failure or malfunction, it may be neces-
sary to open the lid manually.
1. Disconnect the power cord from the wall socket.
2. Remove the plastic plug, located on the left side of the unit,
below the quick button.
3. Pull the cord (attached to the plug) to open the lid lock
manually.
4.3 Lid lock
The centrifuge can be started only with the lid securely closed.
Do not attempt to open the lid until the end of run signal “00” is
displayed.
4.4 Speed selection
The speed (rpm) can be selected from 300 to 6,500rpm with the
knob (right). The set speed can be viewed at all times on the
large LED display (right).

3.2 Rotor maintenance
The rotor should be cleaned thoroughly after each use.
Thor-
ough cleaning must be performed when spinning samples
containing phenol or phenol chloroform.
Periodically inspect
the rotor for dents, dings, scratches, discoloration and cracks. If
any damage to the rotor is found, discontinue use of the rotor
immediately and replace.
3.3 Removing and Installing the angle rotor
Remove the rotor screw from the motor shaft by turning the
screw counterclockwise. Lift the rotor upward and remove from
the centrifuge. Ensure that the motor shaft adapter remains on
the motor shaft (Figure 1). Clean the motor shaft and motor
shaft adapter (see figure 1).
Place the rotor on the motor shaft (figure 1) and over the motor
shaft adapter (see figure 1 and 2). Note: Figure 1 and 2 are
located on the following page.
When loading the rotor, refer to figure 3 (located on the following
page). Loading in the pattern indicated will ensure a balanced
load. Tubes to be loaded should be filled equally by eye. The
difference in the weight between the tubes should not exceed 2-3
grams. A partially loaded rotor may be centrifuged if the loading
scheme for balancing a rotor given in figure 3 is followed.
