• Do not abuse cord. Never use the cord to carry the
tools or 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 receptacles 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
common sense when operating a power tool. Do
not use tool while tired or under the influence of
drugs, alcohol, or medications. A moment of inat-
tention while operating power tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing or
jewelry. 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
before plugging in. Carrying tools with your finger on
the switch or plugging in tools that have the switch ON
invites 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-

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
extends 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
outlet is properly grounded. If the tool should elec-
trically 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.

ance at all times. Proper footing and balance enables
better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection.
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 the plug from the power source before
making any adjustments, changing accessories,
or storing the tool. Such preventive safety mea-
sures 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 535 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 (800) 519-3456 if you have any questions.
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.
Machine Safety
• Threading Machine is made to thread and cut
pipe or bolt and to power roll grooving equipment. 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 power drive 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
prevent 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
entanglement 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 bro-
ken 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
machine chucks. This practice will prevent entan-
glement 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 device 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.

2. Clean up the work area prior to setting up any equipment. Always wipe up any oil that may have splashed
or dripped from the machine to prevent slips and falls.
3. If the workpiece extends more than four (4) feet beyond
the Threading Machine, use one or more pipe stands
to prevent tipping and the oscillation of the pipe.
4. If the workpiece extends beyond the Threading
Machine, set-up guards or barricades to create a minimum of three (3) feet of clearance around the
Threading Machine and workpiece. This “safety zone”
prevents others from accidentally contacting the
machine 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.

tools and chucks without reaching across the
machine.
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.

Checking Thread Length
(Figure 12)
1. Thread is cut to proper length when end of pipe is
flush with edge of dies (Figure 12).
2. Die head is adjustable to obtain proper thread diameter. If possible, threads should be checked with a
thread ring gage (Figure 12). A proper thread is cut
when end of pipe is plus or minus one turn of being
flush with face of ring gage.
Figure 12 – Checking Thread Length
NOTE! If a ring gage is not available, a fitting can be
used. This fitting should be representative of
those being used on the job. The pipe thread
should be cut to obtain 2 or 3 turns hand tight
engagement with fitting. If pipe thread is not proper diameter the index line should be moved in the
direction of the OVER or UNDER size mark on
size bar. (Refer to “Installing Dies In Die Heads”).
Priming Oil Pump
Current 535 Machines have a self-priming gerotor-type
pump. Machines made prior to June 1, 1996 have a
Model A vane-type pump that may require priming.
WARNING
All 535 Threading Machines made prior to June 1, 1996
should have a tube extension on the oil pump priming
port, as well as a top cover access hole, so the pump can
be primed without removing the top cover of the machine.
This will prevent the operator from contacting the internal
gearing of the machine which could result in serious injury.
If your older-style machine has a Model A Vane-Type pump
and does not have a priming port, contact the Ridge Tool
Company at 1-800-519-3456 or e-mail techservices@ridgid.com regarding a retrofit policy.
