8.2 Removing and Cleaning the Needle

When the knob is turned left to the "O" (open) mark, the knob will pop up. Pull out the knob

slowly to remove the needle. Be careful not to damage the two O rings attached to the needle.

To clean the needle you will need an Ultrasonic Cleaner. Prepare a cleaning solution made up of

1/2 of the provided detergent and 1/2 purified water. The cleaning container should hold enough

cleaning solution to cover just the lower portion of the needle. Place the needle in the solution and

run the Ultrasonic Cleaner for approximately 15 minutes.

Note when placing the needle into the detergent, only the lower portion of the needle; up to the O

ring, should be immersed. Do not dip the upper portion of the needle in the detergent.

Before re-inserting the needle into the instrument, ensure it is completely dry or damage to the

instrument may occur.
