5.0 Installation of 1SA Machine on Pipe
5.1 Place the 1SA Saddle Machine squarely on the pipe, as close as possible to the cut line. All 4 spacer
bolts or step spacers should contact the pipe.
5.2 Place the hook of the Boomer (Figure 3 item 1) into the Boomer Eye (Figure 5 Item 7) on the Saddle
(Figure 5 Item 1).
5.3 Place the Spring Snap (Figure 3 Item 4) into the Boomer Eye (Figure 5Item 7) on the other side of the
Saddle (Figure 5 Item 1).
5.4 In order to get a stable installation of the Saddle Machine, the Chain (Figure 3 item 3) of the Boomer
Assembly must be adjusted on the Spring Snap (Figure 3 Item 4) so that the spring is stretched
approximately 1/2" -3/4” (12 - 19mm) when the Boomer is closed.
5.5
When the Chain is properly adjusted, close the Boomer (Figure 3 item 1).
Caution:
Improper tensioning of the boomer assembly or failure to latch the
boomer assembly may result in injury.
