Thank you for the help, Michael.
I cant find the carona wire.
I see a saw tooth looking blade but cant see any wire to
clean.
please guide me further.
I see 2 chrome plunger type connectors, on the left side, that
make contact with the cartridge.
I lifted the door with the green handle, but still see no
wire.
Thank you,
Larry
