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 power tools in explosive atmos-
pheres, such as in the presence of flammable
liquids, gases, or dust. Tools 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.
•Guard or barricade the area when work piece ex-
tends beyond machine. A guard or barricade that
provides a minimum of three (3) feet clearance around
the work piece will reduce the risk of entanglement.
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 out-
let is properly grounded. If the tool 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 a 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 power tool outside, use an out-
door extension cord marked “W-A” or “W”. These
cords are rated for outdoor use and reduce the risk of
electrical shock.
•Use only three-wire extension cords which have
three-prong grounding plugs and three-pole re-
ceptacles which accept the tool’s 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 and
loss of power.
•Keep all electric connections dry and off the
ground. Do not touch plugs or tool with wet hands.
Reduces the risk of electrical shock.
Personal Safety
•Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not
use tool while tired or under the influence of drugs,
alcohol, or medications. A moment of inattention
while operating power tools may result in serious per-
sonal injury.
•Dress properly. Do not wear loose clothing or jew-
elry. Contain long hair. Keep your hair, clothing,
and gloves 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. Carrying tools with your finger on the
switch or plugging in tools that have the switch ON in-
vites accidents.
•Remove 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 overreach. 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 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 the plug from the power source before
making any adjustments, changing accessories
or storing the tool. Such preventive safety measures
reduce the 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 acci-
dents are caused by poorly maintained tools.
•Use only accessories that are recommended for
your tool. 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. 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
Read this operator’s manual carefully before using
the 1224 Threading Machine. Failure to understand
and follow the contents of this manual may result in
electrical shock, fire and/or serious personal injury.
Call the Ridge Tool Company, Technical Service
Department at [phone] if you have any questions.
Foot Switch Safety
Using a threading machine without a foot switch in-
creases 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 be-
come caught in the machine, it will continue to wind
up, pulling you into the machine. Because the ma-
chine has high torque, the clothing itself can bind
around your arm or other body parts with enough
force to crush or break bones.
Machine Safety
•Threading Machine is made to thread and cut pipe
or bolt and to power RIDGID roll grooving equip-
ment. Follow instructions on proper use of this
machine. Do not use for other purposes such as
drilling holes or turning winches. Other uses or
modifying this Threading Machine for other applications
may increase the risk of serious injury.
•Secure machine to bench or stand. Support long
heavy pipe with pipe supports. This practice will pre-
vent tipping.
•Do not wear gloves or loose clothing when oper-
ating machine. Keep sleeves and jackets buttoned.
Do not reach across the machine or pipe. Clothing
can be caught by the pipe or machine resulting in en-
tanglement and serious injury.
•Operate machine from side with REV/OFF/FOR
switch. Eliminates need to reach over the machine.
•Do not use this machine if the foot switch is broken
or missing. Foot switch is a safety device to prevent
serious injury.
•Keep hands away from rotating pipe and fittings.
Stop the machine before wiping pipe threads or
screwing on fittings. Allow the machine to come to
a complete stop before touching the pipe or ma-
chine chucks. This practice will prevent entanglement
and serious injury.
•Do not use this machine to make or break fittings.
This practice is not an intended use of the machine and
can result in serious injury.
•Tighten chuck handwheel and engage rear cen-
tering devise on the pipe before turning on the
machine. Prevents oscillation of the pipe.
•Keep covers in place. Do not operate the machine
with covers removed. Exposure to moving parts may
result in entanglement and serious injury.
•Lock foot switch when machine is not in use
(Figure 1).Avoids accidental starting.

minimum of three (3) feet of clearance around the
Threading Machine and workpiece. This “safety zone”
prevents others from accidentally contacting the ma-
chine or workpiece and either causing the equipment
to tip or becoming entangled in the rotating parts.
5. If necessary, fill the reservoir with RIDGID Thread
Cutting Oil.
6. Make sure FOR/OFF/REV switch is in the OFF position.
7. Position the foot switch so that the operator can safely
control the machine, tools and workpiece. It should
allow the operator to do the following:
•Stand facing the directional switch.
•Use the foot switch with his left foot.
•Have convenient access to the directional switch,
tools and chucks without reaching across the ma-
chine.
Machine is designed for one person operation.
8. Plug the Threading Machine into the electrical outlet
making sure to position the power cord along the clear
path selected earlier. If the power cord does not reach
the outlet, use an extension cord in good condition.
WARNING
To avoid electrical shock and electrical fires, never use
an extension cord that is damaged or does not meet the
following requirements:
•The cord has a three-prong plug similar to shown
in Electrical Safety section.
•The cord is rated as “W”or “W-A”if being used
outdoors.
•The cord has sufficient wire thickness (14 AWG
below 25′/12 AWG 25′ - 50′). If the wire thickness is
too small, the cord may overheat, melting the cord’s
insulation or causing nearby objects to ignite.
To reduce risk of electrical shock, keep all
electrical connections dry and off the ground. Do not
touch plug with wet hands.
9. Check the Threading Machine to insure it is operating
properly.
•Flip the directional switch to FOR (Forward). Press
and release the foot switch. Check that the
Threading Machine rotates in a counterclockwise di-
rection as you are facing the front chuck. Have the
Threading Machine serviced if it rotates in the
wrong direction or if the foot switch does not control
its stopping or starting.
•Place die head in down position. Step on foot switch
and oil should flow from die head. Release foot
switch and return die head to up position.
•Depress and hold the foot switch. Inspect the moving
parts for misalignment, binding, odd noises or any
other unusual conditions that may affect the safe and
normal operation of the machine. If such conditions
are present, have the power drive serviced.
•Flip the directional switch to REV (Reverse). Press
and release the foot switch. Check that that
Threading Machine rotates in a clockwise direc-
tion as you are facing the chuck.
•Release the foot switch and flip the directional
