attached to a length of high grade stainless steel cable, such

While reversing the drill, work the cable in and out several
times to obtain sufficient cleaning. Repeat for each tube.

operational problem. Perform the checks listed in Section
XIV, Startup Procedure and Adjustments to reduce the
chances of repeated fouling.
