7. Remove the bearing press from the shaft
before cleaning the probe parts.
NOTE: Inspect the bearing for wear or black
particles. Clean any dirt from the bearing before
reassembly. Replace the bearing if worn or
damaged. New bearings must be run-in before
initial use, placing the probe in clean water, as
follows:
1. Run 4 minutes on lowest motor setting.
2. Run 5 minutes on medium motor setting.
3. Run 1 minute on highest motor setting.
4. Disassemble generator probe.
5. Clean bearings of run-in dust.
6. Reassemble generator probe.

Autoclaving the stainless steel probes
The generator probes may be sterilised by
autoclaving up to 121ºC. If the probe contains all
Teflon bearings, then it can be autoclaved as an
assembly.
Stainless steel probes: reassembly
1. Insert the lower bearing into the knife end of
the generator tube.
2. For 5mm and 7mm
probes, use the
appropriate bearing
press to set the lower
bearing by using it to
gently push the bearing
into position in the
tube. Remove the
bearing press, leaving
the bearing in place.
3. Slide the upper bearing onto
the shaft so that the flanged
side of the bearing is resting
against the bottom of the
shaft spacer.
4. Insert the shaft into the driven
end of the generator tube.
5. Place the upper probe
tool over the driven end
of the generator tube.
Holding it in place,
invert the probe so that
the knife end points up.
6. Insert the knife into the
processing end of the
generator tube and turn
clockwise to begin
threading it onto the
shaft.
7. Using the other probe
tool, select the correct size
for the probe and insert it
into the knife. Turn the
rotor shaft clockwise until
it stops. DO NOT
TIGHTEN OR TORQUE
THE KNIFE as this may
cause it to bend or break.
