Under or over tightening the feed screw could
result in the 915 “walking” off or slipping inside the pipe.
6. Repeat steps 3 – 5 until depth adjustment screw
touches the pivot nut.
7. Move ratchet from feedscrew to input drive

turns. Be sure pipe is still
flush with drive roll flange.
IMPORTANT! Extreme pressure caused by over ratch-
eting will cause distortion to thin wall pipe.
Do not use power actuated devices
(drills, power drives, impact wrenches, etc.) to drive
the 915 roll groover!
3. Move ratchet from feedscrew to input drive. Turn
