SECTION 1. PREPARATION FOR USE
1.3 STAND-MOUNTING THE TISSUE MASTER (Optional)
An optional stand kit (Part # F22000) may be purchased to mount the
Tissue Master. Contact your authorized dealer or Omni International
at 1-800-776-4431 or 1-770-421-0058 to order.
Assemble the stand:
1. Thread the larger rod onto the base plate.
2. Thread the cross-rod into the motor cradle.
3. Assemble the clamp to the vertical rod.
4. Assemble the cross-rod to the clamp.
5. Insert the motor unit into the motor cradle
and tighten the thumb screws.
SECTION 2. OPERATION
1. Check that the power switch is in the OFF position.
2. Plug the power cord into an appropriate outlet.
WARNING!: DO NOT attempt to plug a cord into an incompatible
outlet.
3. The bottom of the GENERATOR must be submersed in a liquid
before operation to prevent bearing damage.
4. Turn ON the power switch. The speed progressively increases as the
switch slides away from the “O” mark. Run the motor for the
appropriate amount of time required to homogenize the sample.
Moving the homogenizer up and down within the sample during
processing will increase processing eciency.
5. A simple cleaning of the GENERATOR in between samples may be
accomplished by running the probe in a chlorine bleach solution and
then in distilled water to rinse. The probe must still be cleaned
periodically in accordance with section 3.
WARNING: DO NOT process pathogenic material in an open
container. For assistance, contact your authorized dealer or
Omni International at 1-800-776-4431

SECTION 3. GENERATOR PROBE & ACCESSORY MAINTENANCE
3.3 REASSEMBLY
1. Stand the new BEARING at on a table surface and press the smaller
end of the ROTOR SHAFT through the BEARING.
2. Holding the ROTOR SHAFT o the table, push the ROTOR SHAFT
through the hole in the center of the collet wrench and use the wrench
to press the BEARING down the shaft until it snaps into place (the
bearing should feel loose in the bearing seat). (see gures)
4. Slide the COLLET NUT onto the ROTOR SHAFT.
5. Slide the FLEXIBLE COLLET about one centimeter onto the ROTOR
SHAFT.
6. Check that the unit is disconnected from the power source.
7. Insert the ROTOR SHAFT into the MOTOR unit until it stops. Ensure
that the shaft is all the way in the motor unit.
8. Slide the COLLET NUT down the ROTOR SHAFT and thread it onto
the MOTOR unit.
9. Hold down the SHAFT LOCK BUTTON and hand tighten the collet
nut as much as possible. DO NOT use the collet wrench.
10. Slide the GENERATOR TUBE over the ROTOR SHAFT and thread it
onto the MOTOR unit. Firmly hand tighten the tube.
11. See section 3.4 for instructions to run-in the new BEARING. (if the
bearing was not replaced, the Tissue Master is ready for use)

SECTION 3. GENERATOR PROBE & ACCESSORY MAINTENANCE
3.4 BEARING RUN-IN
If the BEARING was replaced, it must be run-in before use.
1. Immerse 1/3 of the GENERATOR in water and run the MOTOR at a
low speed for one minute.
2. Increase speed at one minute intervals for three minutes
3. Run at full speed for one minute.
4. Disconnect the unit from the power source
NOTE: If the probe is excessively noisy, turn the motor o and return to
step 1.
5. Remove the GENERATOR TUBE and clean the BEARING with the
brush. (DO NOT remove the bearing or collet nut)
