Unscrew the front turbo nozzle with the D.H spanners, remove the 3 ceramic jet carriage and replace it with the side 3-jet carriage.

Used in 100 – 150mm (4-6”) with 3 side jets to turn left or right whilst travelling upstream the line, turn into the junction you require by twisting the hose. There is skill required in doing this and you will need a CCTV to get the assembly to the junction you require.
