RGCOMBO2 Roll Groover
Description and Specifications
Important - Before Operating
Description
Before operating the RGCOMBO2 Roll Groover, read and
follow all safety information and instructions in the
operator’s manual.
The Reed Model RGCOMBO2 Roll Groover is designed
to form standard rolled grooves in steel, stainless steel
and aluminum pipe, from 1 1/4” to 6”, in both Schedule 10
and Schedule 40 pipe. The groove is formed by the groove
roll which is fed into the pipe wall. The pipe is supported
on the inside by a drive roll, which is relieved to permit
pipe wall deformation. The formed grooves comply with
the specifications required for mechanical coupling
systems. The only adjustment required is for the depth of
the groove.
Designed for portability, the RGCOMBO2 Roll Groover is
an economical solution to the job-site grooving
requirements in mechanical piping system installations.
Although the RGCOMBO2 design has many improvements
over similar competitors’ models, it is not intended for
production work in the fab shop.
The RGCOMBO2 Roll Groover is designed for use with
the Reed #05301 5301PD Power Drive.

General Safety
Read and follow the safety information and instructions in
the operator’s manual.
Know the location and functions of all controls before using
the machine.
Footswitch Safety
The footswitch of the power drive is for your safety. It lets
you shut off the motor by removing your foot. If clothing
should become caught in the
machine, it could continue to wind
up, pulling you into the machine.
Because the machine has high
torque, the clothing itself can bind
around your arm or other body parts
with enough force to crush or break
bones.

Operator's Manual
Adjusting Groove Depth
Note: To insure the proper groove diameter, a trial groove should
be performed.
3. 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.
Note: The Adjusting Screw must be set for each diameter of pipe.
1. Loosen Adjusting Screw (counterclockwise) enough to permit
advancing of the Groove Roll down to the 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
using the flat gage slot.
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 reverse (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 the Straight Ratchet
Wrench.
Warning: If pipe tends to “walk off” the tool.
a. Verify the pipe sits level, if not level then correct.
b. Verify the pipe rotates in the direction shown by
the sticker on the tool.
c. Offset the far end of the pipe toward the
operator's side (the side with the power drive REV/
OFF/FOR Switch). A pipe offset of 1 inch per 10 ft.
should work. (See Figure 2).
Caution: Keep hands clear of the Power Drive Hand
Wheel/Chuck and Roll Groove Handle area while the
tool is in operation.
111-59200
Caution: Do not over-feed. Allow one complete rotation
of pipe between advances. See Table 2 for details.
4. Continue feeding until Adjusting Screw makes contact with
the top surface of the Roll Groover. 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.
5. Release footswitch to stop machine, and begin retracting Feed
Screw by turning Ratchet Wrench counterclockwise. Retract
Feed Screw enough to remove pipe from machine.
6. Measure groove diameter at two places 90° apart. Both
measurements should be within the listed tolerance of the
dimension shown in Table 1.
7. 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.
8. Periodically check groove depth with a mechanical coupling.
The coupling should fully seat in the groove without
binding or excessive play.
Roll Grooving Tips
1. If pipe tends to “walk off” drive shaft, increase lateral offset of
pipe (see Figure 2 - Pipe Set-Up).
2. If Cover Plate shaves end of pipe, decrease lateral offset of
pipe.
3. If pipe end flare is excessive, lower pipe end to level with roll
groover.
4. If pipe wobbles and/or “walks off” Drive Shaft, raise pipe end
to level with roll groover.
5. Short lengths of pipe (under three feet) may require slight hand
pressure to maintain the lateral offset.

Manual Grooving Instructions
1. Situation:
a. Pipe secured to vise : Securely mount pipe vise (chain
type) on a secure stand or workbench. Allow the pipe to
overhange the vise 5 to 12" so the tool will rotate freely
and not contact the vise. (See Figure 3)
b. Pipe installed (grooving in place): Verify the pipe hangers
can accommodate the weight of the RGCOMBO2 plus
the manual effort required to operate the tool.
2. Mounting the Tool
a. Retract the upper roller by turning the Feed Screw
counterclockwise.
Operator's Manual
d. Advance Adjusting Screw downward until underside
of head touches Depth Gauge.
e. 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.
4. Forming the Groove
a. Advance the Feed Screw the amount specified in Table 1.
Place one hand on the support bar to keep the tool from
twisting when advancing the Feed Screw.
b. Insert the Drive Shaft into the pipe with the Groove Roll on
the outside.
b. Using the Socket Extention and Bent Handle Ratchet,
turn the Crankshaft so the pipe feeds into the tool as indicated
by the arrow.
c. Draw the rolls closer together by turning the Feed Screw
clockwise until the Driveshaft and Groove Roll contact the
pipe lightly.
c. Make one complete revolution of the tool around the pipe
before advancing the Feed Screw again.
d. Place Support Bar into Body of the tool. Place the Support
Bar on the leading side of the tool. When placed correctly,
the "Pipe Direction" arrow will point away from the
support bar.
d. Apply pressure on support bar if needed to keep tool tracking.
3. Set Groove Depth
5. Dismount the tool, retract the Feed Screw fully, lift and
remove the tool from the pipe.
Note: To insure the proper groove diameter, a trial groove should
be performed.
e. Continue grooving until you reach the desired depth. (The
Adjusting Screw can limit Feed Screw advance see the section
on Adjusting Groove Depth for details).
Note: The Adjusting Screw must be set for each diameter of
pipe.
a. Loosen Adjusting Screw (counterclockwise) enough
to permit advancing of Groove Roll down to pipe.
b. Advance Feed Screw (clockwise) until Groove Rollis 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”.
Figure 3. Pipe Set-up
c. Using the Depth Gauge labeled with the pipe size being
grooved, place Depth Gauge under head of Adjusting Screw
using the flat gage slot.
