Forming The Groove - REED RGCOMBO2 Manual De Instrucciones

RGCOMBO2 Roll Groover
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 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 gauge 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
counterclockwise 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.

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.
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
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.
