③ After removing any residual dispense material from the ceramic nozzle interiors, wash
the nozzle ultrasonically in ethyl alcohol or isopropyl alcohol. Use care not to damage
the nozzle during the ultrasonic washing process.
In particular, do not wash nozzle together with other components. Doing so could
cause contact with the other components, possibly resulting in nozzle damage. Always
wash nozzles individually.

Action:
① Insert the lower bearing and seal ring into the screw.
Note: While inserting the lower bearing and seal ring, grasp the hexagon top of the screw and turn the screw
gently in the counterclockwise direction.
Insert these two components one at a time. Do not attempt to insert them together.
② After inserting the lower bearing and seal ring into the screw, insert the screw into the
cartridge body. Be sure that the lower bearing's V-cut is aligned with the cartridge
body's anti-rotation pin when inserting the screw into the cartridge body. This
alignment is facilitated by referring to the guide mark on the cartridge body.
