Operating The 975 Combo Roll
Groover In Place

WARNING

Only drive manually when used for in place appli-
cations. 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 cloth-
ing 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 fit-
ting 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.

Always wear eye protection to protect your eyes
against dirt and foreign objects. Wear steel toe foot-
wear 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
causes.

Setting/Measuring The Groove Diameter

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 approx-
imate 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

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.

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).

Figure 16 – Measuring The Groove Diameter With A

Diameter Tape

6. Compare the measured groove diameter to the re-

quired 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.
