Pipe Set Up In Roll Groover; Setting/Measuring The Groove Diameter - RIDGID 975 Manual De Instrucciones

975 Combo Roll Groover
(Figure 7) . The centerline of the pipe and the cen-
terline of the drive shaft should be parallel to one
another. One way to do this is to level both the pipe
and the power drive/threading machine.
7. Slightly offset the pipe and pipe stands approximately
1 / degree (about 1" over at 10 feet from the roll groo -
2
v er) towards the operator. Proper alignment of the
pipe and roll groover helps to insure proper tracking
of the pipe while grooving. (See Figure 9.)

8. Turn the feedscrew clockwise to bring the groove
roll down in contact with the pipe outside diameter,
then turn the feedscrew one quarter additional turn.
The adjusting screw may need to be loosened (turned
counter-clockwise) to allow the groove roll to contact
pipe. The pipe and roll groover should be secure to
each other at this point.
9. Evaluate the work area and determine if any barriers
are required to keep people other than the operator

away from the equipment and pipe. Guards or barri-
cades should be used to create a minimum of three
(3) feet of clearance around the power drive and
pipe. This "safety zone" prevents others from acci-
dentally contacting the machine or pipe and causing
tipping or becoming entangled in the rotating parts.
10. With dry hands, plug the machine into the properly
grounded outlet.

WARNING
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
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.
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.
Follow operating instructions to reduce the risk of
injury from crushing, tipping, striking and other
causes.

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 approx-
imate only and the groove diameter must be measured
to confirm proper size.
1. Confirm that the equipment and pipe is 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 10A). The groove depth gauge is
