3. Open the gun.

7.2.2.1.4 Disassembling the Firing Unit

Before you can replace the filament, you need to disassemble the firing unit, which contains the
filament holder.

NOTICE

Contamination by dust particles or fingerprints

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

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

Parts and Tools

Lint-free gloves



Hex key, 1.5 mm

Prerequisite

The gun is disassembled.

Procedure

1. Use a hex key 1.5 mm to loosen the three

screws of the firing unit.

INFO:

If possible, only loosen the screws and

do not completely remove them from their
holes.

2. Carefully remove the firing unit.
3. Put the firing unit onto a clean surface.
4. Insert the adjust key into the slots in the brass

retaining washer.
