General Safety Information
WARNING! Read and understand all instructions. Failure
to follow all instructions listed below may
result in electric shock, fire, and/or serious
personal injury.
SAVE THESE INSTRUCTIONS!
Work Area Safety
• Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
• Do not operate electric tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Electric motors create sparks
which may ignite the dust or fumes.
• Keep bystanders, children, and visitors away while
operating a tool. Distractions can cause you to lose
control.
• Keep floors dry and free of slippery materials such
as oil. Slippery floors invite accidents.
Electrical Safety
• Grounded tools must be plugged into an outlet,
properly installed and grounded in accordance
with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do
not use any adapter plugs. Check with a qualified
electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically
malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user.
• Avoid body contact with grounded surfaces. There
is an increased risk of electrical shock if your body is
grounded.
• Don’t expose electrical tools to rain or wet condi-
tions. Water entering an electrical tool will increase the
risk of electrical shock.
• Do not abuse cord. Never use the cord to pull the
plug from an outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace damaged
cords immediately. Damaged cords increase the risk
of electrical shock.
• When operating a tool outside, use an outdoor
extension cord marked “W-A” or “W”. These cords
are rated for outdoor use and reduce the risk of electrical shock.
• Keep all extension cord connections dry and off the
ground. Do not touch plugs with wet hands. This
practice reduces the risk of electrical shock.
• Use only three-wire extension cords which have
three-prong grounding plugs and three-pole receptacles which accept the machine plug. Use of
other extension cords will not ground the tool and increase the risk of electrical shock.
• Use proper extension cords.
(See chart.)
Insufficient
conductor size will cause excessive voltage drop, loss
of power.
Personal Safety
• Stay alert, watch what you are doing and use com-
mon sense when operating a tool. Do not use tools
while tired or under the influence of drugs, alcohol,
or medications. A moment of inattention while oper-
ating tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jew-
elry. Contain long hair. Keep your hair and clothing
away from moving parts. Loose clothes, jewelry, or
long hair can be caught in moving parts.
• Avoid accidental starting. Be sure switch is OFF be-
fore plugging in. Plugging tools in that have the
switch ON invites accidents.
• Remove wrenches or adjusting keys before turning
the tool ON. A wrench or a key that is left attached to
a rotating part of the tool may result in personal injury.
• Do not over-reach. Keep proper footing and bal-
ance at all times. Proper footing and balance enables
better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protec-
tion. Dust mask, non-skid safety shoes, hard hat,
or hearing protection must be used for appropriate
conditions.

Tool Use and Care
• Do not use tool if switch does not turn it ON or
OFF. Any tool that cannot be controlled with the switch
is dangerous and must be repaired.
• Disconnect plug from the power source before
making any adjustments, changing accessories, or
storing the tool. Such preventive safety measures re-
duce risk of starting the tool accidentally.
• Store idle tools out of the reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
• Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that
may affect the tool’s operation. If damaged, have
the tool serviced before using. Many accidents are
caused by poorly maintained tools.
• Use only accessories that are recommended by the
manufacturer for your model. Accessories that may
be suitable for one tool may become hazardous when
used on another tool.
• Keep handles dry and clean; free from oil and
grease. This allows for better control of the tool.
Service
• Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified repair personnel could result in injury.
• When servicing a tool, use only identical replace-
ment parts. Follow instructions in the Maintenance
Section of this manual. Use of unauthorized parts or
failure to follow maintenance instructions may create a
risk of electrical shock or injury.
Specific Safety Information
WARNING
Foot Switch Safety
Using a threading machine without a foot switch increases
the risk of serious injury. A foot switch provides better
control by letting you shut off the motor by removing your
foot. If clothing should become caught in the machine, it will
continue to wind up, pulling you into the machine. Because
the machine has high torque, the clothing itself can bind
around your arm or other body parts with enough force to
crush or break bones.
Roll Groover Safety
• Roll Groover is made to groove pipe and tubing.
Follow instructions in Operator’s Manual on machine uses. Other uses may increase the risk of injury.
• Keep hands away from grooving rolls. Do not wear
loose fitting gloves when operating unit. Fingers
could get caught between grooving and drive rolls.
• Keep guards in place. Do not operate the groover
with guard removed. Exposure to grooving rolls may
result in entanglement and serious injury.
• Set-up Groover on a flat, level surface. Be sure
the machine, stand, and groover are stable. Will prevent tipping of the unit.
• Do not wear loose clothing. Keep sleeves and
jackets buttoned. Do not reach across the machine or pipe. Clothing can be caught by the pipe
resulting in entanglement and serious injury.
• Do not use this Roll Groover with a Power Drive or
Threading Machine that does not have a foot
switch. Foot switch is a safety device to prevent seri-
ous injury.
• When grooving pipe, keep hands away from the
end of the pipe. Do not reach inside pipe end. Will
prevent being cut on sharp edges and burrs.
• Be sure groover is properly secured to the power
drive or threading machine. Carefully follow the setup procedures. Will prevent tipping of the pipe or
grooving unit.
• Properly support pipe with pipe stands. Use two
pipe stands to groove pipe over 36″ long. Prevents
tipping of the unit.
• Use only power drives and threading machines
that operate under 58 RPM. Higher speed machines
increase the risk of injury.
• Lock foot switch when not in use.
(See Figure 1.)
Avoids accidental starting.

Standard Equipment
Description
The RIDGID 918 Heavy Duty Roll Groover forms rolled
grooves in steel, stainless steel, aluminum, PVC pipe and
copper tubing. The grooves are formed by the hydraulic
feeding of a grooving roll into the pipe which is supported by a drive roll.
The 918 Roll Groover includes two (2) groove and drive
shaft sets that can groove the following pipe:
•2″ – 6″ Schedule 10 and 40
•8″ – 12″ Schedule 10 and 8″ Schedule 40
With additional roll sets, the groover can also be adapted
to groove the following:
•2″ – 6″ copper tubing (Types K, L, M, DWV);
•1″ Schedule 10 and 40;
•11/4″ – 11/2″ Schedule 10 and 40.
The 918 Heavy Duty Roll Groover is specifically designed
for use with the RIDGID 300 Power Drive, as well as
RIDGID 535, 535A, 1822, and 1224 Threading Machines.
Different mounting kits are required for each power source.
When properly used, the Model 918 makes
grooves that are dimensionally within the specifications of
AWWA C606-87. Selection of appropriate materials and
joining methods is the responsibility of the system designer and/or installer. Before any installation is attempted,
careful evaluation of the specific service environment, including chemical environment and service temperature,
should be completed.

•1″ – 12″ Schedule 10
•1″ – 8″ Schedule 40
•2″ – 6″ Copper types K, L, M, DWV
•2″ – 8″ Schedule 40 PVC
Do not use to groove 8″ schedule 40 steel
pipe harder than 150 BHN. Doing so may result in improperly formed grooves that do not meet required
specifications.
