7. Remove all traces of polish visible to the eye.

Either rinse the firing unit with warm water containing a few drops of mild (non-abrasive)
detergent OR wipe off all polish with cotton. Do not forget to clean the inside of the aper-
ture. Use a toothpick and cotton to remove as much polishing paste as possible.
Clean until metal parts look shiny and polished. No trace of polish paste should be visible to
the eye.

INFO:

 If a light microscope is available, check around the aperture to ensure the aperture is

completely free from any polishing paste.

8. Completely remove any remaining traces of polish and surface contamination in an ultra-

sonic bath.
Completely immerse the firing unit in Isopropanol or Ethanol. Do not use Acetone. 
Clean for 3-5 minutes.

INFO:

 If an ultrasonic bath is not available, clean the firing unit with plenty of solvent and a

clean piece of cotton. Repeat for at least 3 times.

7.2.2.1.6 Cleaning the Anode

Over time, the filament deposits material on the firing unit and the anode. This can damage the
aperture and reduce the filament life time. You need to remove these deposits during every fila-
ment exchange.

NOTICE

Contamination by dust particles or fingerprints

Dust particles or skin grease can cause contaminations, which lead to flashovers or to bad vac-
uum.

4

Wear lint-free gloves throughout the whole procedure of replacing the filament.

Parts and Tools

Lint-free gloves

Dust and lint-free surface for polishing, e.g., clean printing paper

Wooden toothpicks

Pieces of cotton

Hex Key, 3.0 mm

Stereo light microscope or a magnifying glass

Long reach flexible tweezers

Silicon-free metal polish, e.g., Wenol
