Operation

WARNING
Keep hands away from grooving rolls. Do not wear
loose fitting gloves. Fingers can be crushed be-
tween groove rolls, groove roll and pipe or between
pipe and stabilizer wheel.
Keep hands away from ends of pipe. Do not reach in-
side pipe. Do not touch groove while operating.
Burrs and sharp edges can catch and cut. Fingers
10
can be crushed between groove rolls or between
groove rolls and pipe.
Keep guards in place. Do not operate the roll groov-
er with the guard removed. Exposure to groove
rolls may result in entanglement and serious in-
jury.
Only groove pipe 8" (200 mm) or longer. Grooving
shorter than specified pipe can result in entangle-
ment and crushing injuries.
Do not use this roll groover with a power drive or
threading machine that does not have a foot switch.
Never block a foot switch in the ON position so it
does not control the machine. A foot switch provides
better control by letting you shut off the machine
motor by removing your foot. If entanglement should
occur and power is maintained to the motor, you will
be pulled into the machine. This machine has high
torque and can cause clothing to bind around your
am or other body parts with enough force to crush or
break bones or cause striking or other injuries.
Be sure that the roll groover, pipe, stands and ma-
chine are stable. Be sure the roll groover is properly
set up and secured. This will help prevent tipping of
the equipment and pipe. Properly support the pipe.
This will help to prevent the tipping of the pipe and
equipment.
Always wear eye protection. Wear steel toe footwear
to help protect from tipping tools and falling pipe.
Set up and operate the roll groover according to
these procedures to reduce the risk of injury from
machine tipping, entanglement, crushing, striking
and other causes, and to help prevent equipment
damage.
1. Confirm that the machine and work area is properly set
up and that the work area is free of bystanders and
other distractions. The operator should be the only
person in the area when the machine is operated.
2. Position the foot switch for proper operation as shown
in Figure 18.
3. Check the roll groover for proper operation. While
keeping your hands clear of moving parts:
• Move the power drive/threading machine REV/O-
OFF/FOR switch to the REV position. Press and
release the foot switch. Drive roll should rotate
clockwise (see Figure 14) matching the pipe ro-
tation decal on the groover. If the groover does not
rotate in the correct direction, or the foot switch
does not control the machine operation, do not use
the machine until it has been repaired.
• Depress and hold the foot switch. Inspect the mov-
ing parts for misalignment, binding, odd noises or
any other unusual conditions. Confirm that the ma-
chine rotates less than 58 rpm. Higher speeds can
increase the risk of injury. Remove foot from the foot
switch. If any unusual conditions are found, do not
use the machine until it has been repaired.
