to preventing the operator from being exposed to a rotating blade, the sealed chamber assembly protects the operator
from hazardous aerosols generated during homogenizing.
Assembly:
1) Screw the rotor shaft assembly into the cover plug. Tighten snugly using the multi-wrench (supplied in the tool
kit).
2) With the sharpened side of the blade up, mount the blade on the rotor shaft engaging the tabs in the knife
collar with the cutout in the center of the blade and secure with the acorn nut.
THE KNIFE BLADES ARE SURGICALLY SHARPENED AND SHOULD BE HANDLED
3) Tighten snugly with the multi wrench, while holding the rotor shaft steady with the 1/4"hex wrench.
4) Insert the rotor shaft assembly and cover the plug with the blade attached to the chamber.
5) Screw the chamber cover onto the chamber. Note that the threads on the chamber and cover are left hand
threads and are screwed together by turning the cover counter clockwise. These two parts should be tightened
securely. There is no way in which the blade can be attached to the motor unit without the chamber being
attached. This is to ensure that the operator is never exposed to a rotating blade.
6) Attach the filled chamber to the cover and cover plug/rotor shaft assembly.
Attachment of the Safety Sealed Assemblies with Blade Assembly to the Homogenizer:
1) All PRO Safety Sealed Assemblies are fitted to the motor unit by inserting the upper end of the
generator into the collar end of the motor.
2) Align the vertical slots in the PRO Safety Sealed Assembly with the locating pins in the motor collar by
rotating the PRO Safety Sealed Assembly.
3) Once aligned, push the PRO Safety Sealed Assembly inward as far as possible and turn the PRO Safety
Sealed Assembly left. The collar is spring loaded so you will feel some resistance as you push the
generator inward and turn it.
AT NO POINT SHOULD EXCESSIVE FORCE BE NECESSARY TO CONNECT
THE PRO SAFETY SEALED ASSEMBLY TO MOTOR UNIT
4) Once you have turned the PRO Safety Sealed Assembly ¼ turn, release the PRO Safety Sealed
Assembly and you will hear a distinct click which is the PRO Safety Sealed Assembly dropping into its
locked position.
5) To prevent the PRO Safety Sealed Assembly from disengaging while being used, insert the safety clip
between the upper collar of the PRO Safety Sealed Assembly and the bottom of the motor collar.
6) To disconnect the PRO Safety Sealed Assembly from the motor unit, remove the safety clip, push the
PRO Safety Sealed Assembly up into the motor collar as far as possible and turn the PRO Safety
Sealed Assembly clockwise ¼ turn. The PRO Safety Sealed Assembly will be pushed out of the motor
collar by the force of the internal spring.
