The tapping procedure is finished when the
drilling rod can rotate without any resistance.
NOTE: You will feel less resistance twice - once
in the beginning when the pilot drill has perforated
the pipe wall and secondly when the cutter is
completely through.
WARNING: Always control the drilling rod.
Unlock the drilling rod by operating the orange
tapping device lock. Then pull the drilling rod
completely upwards above the slide gate valve.
(If assistance to get the cutter out is needed, turn
the drilling rod clockwise.)
(NEVER turn the drilling rod counterclockwise.
This can damage the cutter.)
(Be aware of the fact that the pressure inside
the pipeline may automatically move the rod
upwards. Avoid being above the rod with your
hands or face.)
WARNING: Always control the drilling rod.
Close the slide gate valve.
Release pressure from the dome by opening bleed
valve.
