RG6 Portable Roll Groover
Caution: Do not over-feed. Allow one complete rotation
of pipe between advances. (See Table 1 for details.)
5. Continue feeding until Adjusting Screw makes contact with Top
Plate. Allow pipe to make two complete rotations in bottomed
position to insure uniform groove depth.
Warning: Do not tighten Feed Screw after Adjusting Screw
bottoms out. Damage to the Adjusting Screw may result.
6. Release footswitch to stop machine, and begin retracting Feed
Screw by turning Ratchet Wrench counterclockwise. Retract
Feed Screw enough to remove pipe from machine.
7. Measure groove diameter at two places 90
°
apart. Both
measurements should be within the listed tolerance of the
dimension shown in Table 2 for steel pipe and other IPS pipe.
See Table 3 for copper tubing.
8. To increase groove diameter tighten Adjusting Screw. To
decrease groove diameter loosen Adjusting Screw.
Each 1/4
turn of Adjusting Screw will change groove diameter by
approximately .02”.
Note:
Once groove depth has been set, following grooves will
be same depth.
9. Periodically check groove depth with a mechanical coupling.
The coupling should fully seat in the groove without
binding or excessive play.

Adjusting Groove Depth
Note:
To insure the proper groove diameter, a trial groove should
be performed.
Note:
The Adjusting Screw must be set for each diameter of pipe.
1. Loosen Adjusting Screw (counterclockwise) enough to permit
advancing of Groove Roll down to pipe.
2. Advance Feed Screw (clockwise) until Groove Roll is snug
against top of pipe. Be sure Groove Roll contacts pipe and
Adjusting Screw head does not bottom out.
Note:
Trial groove pipe should be deburred for best results.
Burr on inside of pipe will raise pipe away from drive shaft,
causing inaccurate set-up adjustment. After proper groove
depth has been verified by trial groove, deburring of following
pipes is not required. See Step 1 of
“Pipe Preparation”.
3. Using the Depth Gauge labeled with the pipe size being
grooved, place Depth Gauge under head of Adjusting Screw.
4. Advance Adjusting Screw downward until underside of head
touches Depth Gauge.
5. Remove Depth Gauge.
Note:
It may be necessary to readjust Adjusting Screw after
trial groove is made. Each 1/4 turn of Adjusting Screw will
produce a .02” change in diameter of rolled groove. Tightening
Adjusting Screw will increase groove diameter. Loosening
Adjusting Screw will decrease groove diameter.
Forming the Groove
1. Place the power drive switch in the “REV” position for clockwise
rotation of the drive shaft and pipe.
2. Step on power drive footswitch and apply light pressure on
pipe by advancing Feed Screw with Ratchet Wrench.
Warning: If pipe begins to “walk off” drive shaft, stop the
machine. The pipe must be adjusted by leveling or by
increasing the lateral offset. See Steps 4 and 5 of “Pipe
Setup”.
3. To help prevent “walking” keep pressure on pipe with hand.
4. With pipe tracking properly and end of pipe against cover
plate, step on footswitch and begin advancing Feed Screw
with Ratchet Wrench, allowing one complete rotation of pipe
between strokes of Ratchet Wrench.
