touches the step of the depth gauge. Turn the groove
depth gauge to the grooving position (Figure 15B). If
gauge is not in the grooving position it will prevent
grooving and may be damaged.
Operating The 975 Combo Roll
Groover In Place
Only drive manually when used for in place applications. Do not use powered devices (such as drills
or impact tools) to drive the roll groover when used
in place. Use of powered devices can damage the
groover and increase the risk of injury.
Do not wear loose clothing when operating the roll
groover. Keep sleeves and jackets buttoned. Do
not reach across the machine or pipe. Loose clothing can become entangled in rotating parts and
cause crushing injuries.
Keep hands away from grooving rolls. Do not groove
pipes shorter than specified. Do not wear loose fitting gloves. Fingers can be crushed between groove
rolls or between groove roll and pipe.
Keep hands away from ends of pipe. Do not reach
inside pipe. Burrs and sharp edges can catch and
cut. Fingers can be crushed between groove rolls or
between groove roll and pipe.

4. Prepare a test groove (follow the steps for “Forming
the Roll Groove).
5. Measure the groove diameter. The best method for
measuring groove diameter is the use of a diameter
tape (See Accessories Section). Snugly wrap the
diameter tape around the pipe in the groove. Make
sure that the tape sits flat in the bottom of the groove,
and read the groove diameter (See Figure 16).
Always wear eye protection to protect your eyes
against dirt and foreign objects. Wear steel toe footwear to protect feet from tipping tools and falling
pipe. When working in place, wear a hard hat.
Follow operating instructions to reduce the risk of
injury from crushing, tipping, striking and other
Setting/Measuring The Groove Diameter
NOTICE Due to differing pipe characteristics, a test
groove should always be performed before the first
groove of the day or when changing pipe size, schedule
or material. Groove diameter setting gauges are approximate only and the groove diameter must be measured to
confirm proper size.
1. Confirm that the equipment and pipe are properly
set up. Improper pipe preparation can effect the
accurate set up of the groove depth gauge. The
groove roll should be touching the pipe.
2. Adjust the groove depth gauge so that the correct step
of the gauge is under the head of the adjusting screw
(Figure 15A). The groove depth gauge is designed for
use with pipe. See “Setting The Groove Diameter For
Copper Tube” for use with copper tube.
3. Turn the adjusting screw clockwise until the head

Diameter Tape
6. Compare the measured groove diameter to the required groove diameter as shown in Table I or III or as
specified by the groove fitting manufacturer. If the
measured groove is outside of the required groove
diameter, the adjusting screw must be repositioned to
give the correct groove diameter.
• To increase groove diameter, turn the adjusting
screw clockwise.

• To decrease groove diameter, turn the adjusting
screw counter-clockwise.
• Each 1/4 turn of the adjusting screw changes the
groove diameter approximately 0.02".
7. Repeat steps 4-6 until the groove diameter is within
specifications. If the first groove is too large, the
Groove can be adjusted and the groove made smaller. If the groove is too small, another groove will
need to be made. Proper groove diameter is important
to insure connection performance. Out of specification
grooves could cause joint failure.
Forming The Roll Groove
1. Confirm that the equipment and pipe are properly
set up.
2. Assume a proper operating position. Make sure that
your footing is good and you are well balanced.
3. Make sure that the feedscrew has been tightened 1/4
4. Remove the ratchet from the feedscrew and securely install in the extension. (In close quarters applications, the extension does not need to be used.)
5. Turn the ratchet clockwise as viewed from the back of
the roll groover (this will match the arrows cast into the
back of the roll groover, see Figure 17). Watch the
groover rotate and be sure that the cover plate of the
roll groover stays in contact with the end of the pipe.
If the roll groover starts to move away from the pipe
end, stop rotating the ratchet to prevent the roll
groover from spiraling off the pipe end and falling.
The roll groover support arms can be pushed on to
help bring the cover plate back in contact with the pipe
end. If needed, re-mount the roll groover to the pipe.
(see “Mounting Roll Groover to Pipe” section). If the
pipe end is deformed, it will need to be cut off and a
new groove prepared.
6. Continue rotating the ratchet until the roll groover
completes at least a full rotation around the pipe.
Remove the ratchet from the extension and attach to
the feedscrew. Tighten the feedscrew another 1/4
turn. Remove the ratchet from the feedscrew and
securely attach to the extension. Do not tighten the
feedscrew more than 1/4 turn per pipe rotation. Aggressive tightening of the feedscrew can cause excessive groove flare and can cause the roll groover to
walk off the pipe. Continue rotating the ratchet to
drive the roll groover around the pipe while monitoring
the position of the cover plate to the end of the pipe.
7. Continue tightening the feedscrew 1/4 turn per groove
revolution around pipe until the head of the adjusting
screw stops against the top of the roll groover. Do not
continue tightening the feedscrew after the adjusting
screw reaches the top of the roll groover, this can
damage the adjusting screw. Rotate the roll groover
at least two more full rotations around the pipe after
the adjusting screw reaches the top of the roll groover
to insure uniform groove depth.
8. Move the ratchet to the feedscrew. Securely grasp the
roll groover. Turn the feedscrew counter-clockwise
and retract the groove roll so that the roll groover can
be removed from the pipe. Do not drop the roll
9. Inspect the groove.
• Make sure that the groove is fully formed.
• Check the groove diameter and make sure it is
within specification.
• Check any other items required by the fitting manufacturer.
If any problems are found, the groove cannot be used.
Maintenance Instructions
Make sure the power drive switch is in the OFF
position and the unplugged before performing any
maintenance or making any adjustments.
Lubricate the 975 Combo Roll Groover with a good general purpose grease once a month.
• Grease fittings are located on the side of the operator’s side of the base, the front of the slide block,
and the end of the groove roll shaft (See Figure 2).
Add grease until a small amount is pushed out.
• Apply a light coat of grease to the feedscrew.
Figure 17 – Turning the Ratchet in the Direction of the
Ridge Tool Company

• The gear box of the 975 Combo Roll Groover is
greased for life and does not require the addition of
any grease unless the gear box is opened.
Retaining Ring
See Inspection Section for other information on maintenance.
Clean the driveshaft knurls with a wire brush on a daily
basis or more often if needed.
Changing Roll Sets
When changing roll set parts, always make
sure drive and groove roll markings match. Mismatched
parts can make improper grooves and cause leaks.
Remove the roll groover from the power drive or threading machine and place on a stable work bench.
Required Tools:
• 3/8" Hex Wrench
• 3/32" Hex Wrench
• .070" External Retaining Ring Pliers
