Pipe wall thickness cannot exceed the maximum wall thickness specified in the list below.
1. Flip the directional switch from OFF and step on power drive foot switch while applying slight
downward pressure on the feed handle.
If pipe begins to "walk off" the drive roll, stop the machine and check "Pipe Set-Up" procedure.
2. To help prevent "walking", apply pressure on pipe with right hand, away from operator when
running the power drive or machine in FORWARD mode, toward operator when running the
power drive or machine in REVERSE mode. (Fig 3 & 4)
NOTE! If power drive runs in FOR position, push the pipe away from operator. If power drive runs
in REV, pull the pipe towards operator.
3. With pipe tracking properly and backside of pipe against drive roll flange, step on foot switch
and continue downward pressure until feed handle rests on the base of Roll Groover.
NOTE! Do not overfeed upper groove roll. Maintain constant downward pressure, pausing to
allow one pipe revolution before increasing downward pressure.
4. After feed handle comes to rest on base of 916 Roll Groover allow two (2) complete pipe revo-
lutions to even out groove depth.
5. Release foot switch and slip directional switch to OFF.
6. Pull feed handle upward and check groove diameter (See list below).
7. To decrease groove diameter, tighten depth adjustment screw. To increase groove diameter,
loosen depth adjustment screw.
NOTE! Once groove depth is determined, additional grooves will have the same depth.
8. Periodically check groove depth with a "pi" or diameter tape.
