5.1.9 Make sure that all Rest Pins (Figure 2 Item 2) on both sides of the Band are making contact with the pipe.
Note: If some of the Rest Pins (Figure 2 Item 2) of the Band are not making contact with the pipe it may be an
indication that the Band is out of square with the pipe and the Band must repositioned and resquared to the pipe.
Note: Never use a hard faced hammer to square the band on the pipe as the wheels of the Band Crawler may
have difficulty crossing the damaged area.
5.1.10 The Band Crawler is ready to mount onto the Band.
Note: There is no need for an out-of-round coping device because of the flexibility of the band allows it to conform
to the contour of the out- of-round pipe when locked into position on pipe.
