Step 1
:
Seal cartridge
: Extract the cartridge from
the barrel using the multipurpose spanner. The
cartridge should be replaced every time it is
disassembled.
If the o-ring at the front of the cartridge is to be
replaced, removed it with a screwdriver, insert
the new o-ring, ensuring it is positioned correctly.
When reassembling,
ensure the cartridge is
inserted in the correct orientation (white seal
facing outwards). Push the cartridge until it clips
into the barrel. Coat the white seal and the anti-
extrusion ring with a fine layer of vaseline.

: Unscrew the HV contact
using a 4mm socket wrench. The fibre washer
should always be replaced whenever the device
is disassembled. Replace the HV contact if nec-
essary, then screw back into the barrel.
