Warnings*
WARNING
Read all safety warnings, instructions, illustra-
tions and specications provided with this power
tool. Failure to follow all instructions listed below
may result in electric shock, re and/or serious
injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE!
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work Area Safety
Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
Do not operate power tools in explosive atmo-
spheres, such as in the presence of flam mable liq-
uids, gases, or dust. Power tools create sparks which
may ignite the dust or fumes.
Keep children and bystanders away while operat-
ing a power tool. Distractions can cause you to lose
control.
Electrical Safety
Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adap ter
plugs with earthed (grounded) power tools. Un -
modified plugs and matching outlets will reduce risk of
electric shock.
Avoid body contact with earthed or grounded sur-
faces such as pipes, radiators, ranges and refrig-
erators. There is an increased risk of electrical shock
if your body is earthed or grounded.
Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the risk
of electrical shock.
Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or

moving parts. Damaged or entangled cords increase
the risk of electric shock.
When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of elec-
tric shock.
If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces
the risk of electric shock.
Personal Safety
Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not
use a power tool while you are tired or under the
influence of drugs, alcohol, or medication. A mo -
ment of inattention while operating power tools may
result in serious personal injury.
Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
Prevent unintentional starting. Ensure the switch is
in the OFF-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch
ON invites accidents.
Remove any adjusting key or wrench before turn-
ing the power tool ON. A wrench or a key left at -
tached to a rotating part of the power tool may result in
personal injury.
Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
Dress properly. Do not wear loose clothing or
jewel ry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry, or long hair
can be caught in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.

Power Tool Use And Care
Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it is
designed.
Do not use the power tool if the switch does not
turn it ON and OFF. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
Disconnect the plug from the power source and/or
remove the battery pack, if detachable, from the
power tool before making any adjustments, chang-
ing accessories, or storing power tools. Such pre-
ventive safety measures reduce the risk of starting the
power tool accidentally.
Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the pow -
er tool or these instructions to operate the power
tool. Power tools are dangerous in the hands of
untrained users.
Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power tools
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations dif-
ferent from those intended could result in a hazardous
situation.
Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
Service
Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
Do not use this machine if the foot switch is bro-
ken or missing. The foot switch provides safe control
of the machine, such as shut-off in case of entangle-
ment.
One person must control the work process, ma -
chine operation and foot switch. Only the operator
should be in the work area when the machine is run-
ning. This helps reduce the risk of injury.
Never reach into the machine front chuck or rear
centering head. This will reduce the risk of entangle-
ment.
Read and understand these instructions and the
instructions and warnings for all equipment and
materials being used before operating this tool to
reduce the risk of serious personal injury.

Pre-Operation Inspection
WARNING
Before each use, inspect your threading machine
and correct any problems to reduce the risk of seri-
ous injury from electric shock, crushing and other
causes and prevent threading machine damage.
1. Make sure that the threading machine is unplugged
and the REV/OFF/FOR (2/0/1) Switch is in OFF (0)
position.
2. Clean any oil, grease or dirt from the threading
machine, including the handles and controls. This
aids inspection and helps prevent the machine or
control from slipping from your grip. Clean and main-
tain the machine per the Maintenance Instructions.
3. Inspect the threading machines for the following:
Inspect the cords and plugs for damage or modifi-
cation.
Proper assembly, maintenance and completeness.
Any broken, worn, missing, misaligned or binding
parts or other damage.
Presence and operation of the foot switch. Confirm
that foot switch is attached, in good condition, that it
cycles smoothly and does not stick.
Presence and readability of the warning labels
(See Figure 1 & 2).
Condition of the dies, cutter wheel and reamer cut-
ting edges. Dull or damaged cutting tools increase
required force, produce poor results and increase
the risk of injury.
Any other condition which may prevent safe and
normal operation.
If any problems are found, do not use the threading
machine until the problems have been repaired.
4. Inspect and maintain any other equipment being
used per its instructions to make sure it is functioning
properly.
999-998-086.09_REV. C 7
Selection of appropriate materials and instal-
lation, joining and forming methods is the responsibility of
the system designer and/or installer. Selection of improp-
er materials and methods could cause system failure.
Stainless steel and other corrosion resistant materials can
be contaminated during installation, joining and forming.
This contamination could cause corrosion and premature
failure. Careful evaluation of materials and methods for the
specific service conditions, including chemical and tem-
perature, should be completed before any installation is
attempted.
Machine Assembly
WARNING
To reduce the risk of serious injury during use, fol-
low these procedures for proper assembly.
Failure to mount the threading machine to a stable
stand or bench may result in tipping and serious
injury.
REV/OFF/FOR Switch should be OFF and machine
unplugged before assembly.
Use proper lifting techniques. RIDGID 535 threading
machines weigh 260 lbs. (118 kg) or more.
Mounting on Stands
The Threading Machines can be mounted on various
RIDGID Threader Stands. Refer to RIDGID catalog for
stand information and to the respective Stand Instruction
Sheet for mounting instructions.
Mounting on Bench
The machines can be mounted on a level, stable bench. To
mount the unit on a bench, use four 5/16"-18 UNC bolts in

the die head. See Die Head Set-Up and Use section
for details.
7. Swing the cutter, reamer and die head up away from
the operator. Make sure they are stable and will not fall
in the work area.
8. If pipe will extend past the chip tray in the front of the
machine or more than 4' (1,2 m) out of the rear of the
machine, use pipe stands to support the pipe and pre-
vent the pipe and threading machine from tipping or
falling. Place the pipe stands in line with machine
chucks, approximately 1/3 of distance from end of the
pipe to the machine. Longer pipe may need more than
one pipe stand. Only use pipe stands designed for
this purpose. Improper pipe supports or supporting
the pipe by hand can cause tipping or entanglement
injuries.
9. Restrict access or set-up guards or barricades to
create a minimum of 3' (1 m) clearance around the
threading machine and pipe. This helps prevent non-
operators from contacting the machine or pipe and
reduces the risk of tipping or entanglement.
10. Position the foot switch as shown in Figure 17, to allow
a proper operating position.
11. Check the level of RIDGID Thread Cutting Oil. Remove
the chip tray and oil pan liner; see that the filter screen
assembly is fully submerged in oil. See Oil System
Maintenance.
12. With the REV/OFF/FOR Switch in OFF position, run the
cord along a clear path. With dry hands, plug the
power cord into properly grounded outlet. Keep all
connections dry and off the ground. If the power cord is
not long enough use an extension cord that:
Is in good condition.
Has a three-prong plug like on the threading machine.
Is rated for outdoor use and contains a W or W-A in
the cord designation (e.g. SOW).
Has sufficient wire size. For extension cords up to 50'
(15.2 m) long use 16 AWG (1.5 mm
2
) or heavier. For
extension cords 50'-100' (15.2 m - 30.5 m) long
use 14 AWG (2.5 mm
2
) or heavier.
13. Check the threading machine for proper operation.
With hands clear of moving parts:
Move the REV/OFF/FOR (2/0/1) Switch to the FOR
(1) position. Press and release the foot switch. Chuck
should rotate counter-clockwise when viewed from
the carriage end (see Figure 22). Repeat for REV
position chuck should rotate clockwise. If the thread-
ing machine does not rotate in the correct direction,
or the foot switch does not control the machine
Machine and Work Area Set-Up
WARNING
Set up the Threading Machine and the work area
according to these procedures to reduce the risk of
injury from electric shock, machine tipping, entan-
glement, crushing and other causes, and to help
prevent threading machine damage.
Secure machine to stable stand or bench. Properly
support pipe. This will reduce the risk of falling
pipe, tipping and serious injury.
Do not use the Threading Machines without a prop-
erly operating foot switch. A foot switch provides
better control by letting you shut off the machine
motor by removing your foot.
1. Check work area for:
Adequate lighting.
Flammable liquids, vapors or dust that may ignite. If
present, do not work in area until source is identified,
removed or corrected, and area is completely ven-
tilated. The threading machine is not explosion
proof and can cause sparks.
Clear, level, stable and dry place for all equipment
and operator.
Good ventilation. Do not use extensively in small,
enclosed areas.
Properly grounded electrical outlet of the correct
voltage. Check the machine serial plate for required
voltage. A three-prong or GFCI outlet may not be
properly grounded. If in doubt, have outlet inspected
by a licensed electrician.
2. Inspect the pipe to be threaded and associated fit-
tings. Determine the correct equipment for the job,
see Specifications. Do not use to thread anything oth -
er than straight stock. Do not thread pipe with fittings or
other attachments. This increases the risk of entan-
glement.
3. Transport equipment to work area. See Preparing
Machine for Transport for information.
4. Confirm equipment to be used has been properly in -
spected and assembled.
5. Confirm that the REV/OFF/FOR Switch is in the OFF
position.
6. Check that the correct dies are in the die head and are
properly set. If needed, install and/or adjust the dies in
999-998-086.09_REV. C 9
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. Remove foot from
the foot switch. If any unusual conditions are found,
do not use the machine until it has been repaired.
For 535 Auto Chuck machines, confirm that the
FOR rotation closes the chuck and REV rotation
opens it.
Place die head in the use position. Depress and hold
the foot switch. Check for oil flow through the die
head. Remove foot from the foot switch.
14. Move the REV/OFF/FOR Switch to the OFF posi-
tion, and with dry hands unplug the machine.
Die Head Set-Up and Use
The 535 Manual Chuck/535 Auto Chuck Threading Ma -
chines can be used with a variety of RIDGID Die Heads to
cut pipe and bolt threads. Information is included here for
Quick-Opening, Self-Opening and Semi-Automatic Die
Heads. See the RIDGID catalog for other available die
heads.
Die Heads using Universal Dies for pipe require one set of
dies for each of the following pipe size ranges: (
1
/
8
"), (
1
/
4
" and
3
/
8
"), (
1
/
2
" and ¾") and (1" through 2"). NPT/NPSM dies
must be used in NPT Die Heads and BSPT/BSPP dies
must be used in BSPT Die Heads The cam plate is
marked for each.
Die heads using Bolt dies require a dedicated set of dies
for each specific thread size.
High Speed dies are recommended for threading at 40
rpm and higher speeds. See the RIDGID catalog for dies
available for your die head.
Always cut a test thread to confirm proper thread size after
changing/adjusting the Dies.
Removing/Installing Die Head
Insert/remove Die Head Post into mating hole in car-
riage. When fully inserted, the Die Head will be held in

Operating Instructions
WARNING
Do not wear gloves or loose clothing. Keep sleeves
and jackets buttoned. Loose clothing can become
entangled in rotating parts and cause crushing and
striking injuries.
Keep hands away from rotating pipe and parts. Stop
the machine before wiping threads or screwing ont-
tings. Do not reach across the machine or pipe. To
prevent entanglement, crushing or striking injuries,
allow machine to come to a complete stop before
touching the pipe or machine chucks.
Do not use this machine to make or break (tighten or
loosen) ttings. This can cause striking or crushing
injuries.
Do not use a threading machine without a properly
operating foot switch. Never block a foot switch in
the ON position so that it does not control the
threading 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
arm or other body parts with enough force to crush
or break bones or cause striking or other injuries.
One person must control both the work process
and the foot switch. Do not operate with more than
one person. In case of entanglement, the operator
must be in control of the foot switch.
Follow operating instructions to reduce the risk of
injury from entanglement, striking, crushing and
other causes.
1. Make sure that 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 per-
son in the barricaded area while the machine is oper-
ated.
The cutter, reamer and die head should be up away
from the operator, do not place in the operating posi-
tion. Make sure they are stable and will not fall in the
work area.
Fully open the chucks of the threading machine. For
Manual Chuck machines, turn the front chuck hand-
wheel clockwise (see Figure 16). For Auto Chuck ma -
chines, move the REV/OFF/FOR (2/0/1) Switch to the
REV (2) position, depress and release the foot switch.
2. Insert pipe shorter than 2 (0,6 m) from the front of the
machine. Insert longer pipes through either end so that
the longer section extends out beyond the rear of
the threading machine. Confirm that pipe stands are
properly placed.
3. If needed, mark the pipe. Place pipe so that the area to
be cut or end to be reamed or threaded is approxi-
mately 4" (100 mm) from the front of the chuck. If
closer, the carriage may strike the machine during
threading and damage the machine.
4. Chuck the pipe.
For Manual Chuck machines: Turn the rear center-
ing device counterclockwise (viewed from rear of
machine) to close down onto pipe. Make sure that the
pipe is centered in the jaws. This improves pipe sup-
port and gives better results.

the inserts. Use repeated and forceful counterclockwise
spins of the handwheel to secure the pipe in front
chuck.
For Auto Chuck machines: Move the REV/OFF/ FOR
(2/0/1) Switch to the FOR (1) position and step on the
foot switch. The machine will automatically center and
grip the pipe or stock. If pipe is chucked off center, run
the machine in REV to release and re-chuck. Do not
handle rotating pipe. Auto chuck machines only grip
pipe when rotating.
5. Assume a proper operating position to help maintain
control of the machine and pipe (See Figure 17).
Stand on the REV/OFF/FOR Switch side of the
machine with convenient access to the tools and
switch.
Be sure that you can control the foot switch. Do not
step on foot switch yet. In case of emergency, you
must be able to release the foot switch.
Be sure that you have good balance and do not
have to overreach.
Figure 17 – Operating Position
Changing Operating Speeds
535 Threading machines come in single and multiple
speed versions. Any speed may be used for cutting and
reaming.

Cutting with No. 820 Cutter
1. Open cutter by turning the feed screw counterclock-
wise. Lower the cutter into cutting position. Align the
cutter wheel with the mark on pipe. Cutting threaded
or damaged sections of pipe can damage the cutter
wheel.
Length Gauge Use Place cutting wheel blade against
the end of pipe and set length gauge pointer to “0”
(Figure 20A). Raise cutter and turn carriage hand-
wheel until the pointer is at the length desired. Lower
the cutter into cutting position. See Figure 20B.

2. Tighten the cutter feed screw handle to bring the cut-
ter wheel firmly in contact with the pipe while keeping
the cutter wheel aligned with the mark on pipe.
3. Move the REV/OFF/FOR Switch to the FOR position.
4. With both hands, grasp the pipe cutter feed handle.
5. Depress the foot switch.
6. Tighten the feed screw handle one-half turn per rota-
tion of the pipe until the pipe is cut. More aggressive
tightening of the handle reduces cutter wheel life and
increases burr formation. Do not support the pipe
by hand. Let the cut off piece be supported by the
threading machine carriage and pipe stand.
Figure 21 – Cutting Pipe with Cutter
7. Remove foot from the foot switch.
8 Move the REV/OFF/FOR Switch to the OFF position.
9. Raise the cutter into position up away from the oper-
ator.
Reaming with No. 341 Reamer
1. Move the reamer into reaming position. Make sure
that it is securely positioned to prevent it from moving
during use.
2. Extend reamer by releasing latch and sliding the
reamer towards pipe until the latch engages.
3. Move the REV/OFF/FOR (2/0/1) Switch to the FOR
(1) position.
4. With both hands, grasp the carriage handwheel.
5. Depress the foot switch.

8. Move the REV/OFF/FOR Switch to the OFF position.
9. Retract the reamer by releasing latch and sliding the
reamer away from pipe until the latch engages.
10. Move reamer up away from the operator.
Threading Pipe
Due to differing pipe characteristics, a test thread should
always be performed before the first thread of the day or
when changing pipe size, schedule or material.
1. Lower the die head into the threading position. Confirm
that the dies are correct for the pipe being threaded and
properly set. See the Die Head Set-Up and Use section
for information on changing and adjusting dies.
2. If needed, chose a correct operating speed for the
application. See Changing operating Speeds section.
3. Move the REV/OFF/FOR Switch to the FOR position.
4. With both hands, grasp the carriage handwheel.
5. Depress the foot switch.
6. Confirm cutting oil flow through the die head. Current
535 Threading Machines use through head oiling.
Machines made prior to 1996 have an oil spout which
must be swung to the down position to flood dies
with oil.
Figure 23 – Threading Pipe
7. Turn carriage handwheel to move the die head to
the end of pipe. Apply slight force to the handwheel to
start the die head onto the pipe. Once the die head
starts threading, no more force is required on the
carriage handwheel.
999-998-086.09_REV. C 15
535 Manual Chuck/535 Auto Chuck Threading Machines
8. Keep your hands away from the rotating pipe. Make
sure the carriage does not hit the machine. When the
thread is complete, open the die head (if the die head
does not open automatically). Do not run machine in
Reverse (REV) with dies engaged.
9. Remove foot from the foot switch.
10. Move the REV/OFF/FOR Switch to the OFF posi-
tion.
11. Turn the carriage handwheel to move the die head
past the end of the pipe. Raise the die head into
position up away from the operator.
12. Remove the pipe from the machine and inspect the
thread. Do not use the machine to tighten or loosen fit-
tings on the thread.
Threading Bar Stock/Bolt Threading
Bolt threading is similar to the pipe threading process. The
stock diameter should never exceed the thread major diam-
eter.
When cutting bolt threads, the correct dies and die head
must be used. Bolt threads may be cut as long as needed,
but make sure the carriage does not hit the machine. If long
threads are required:
1. At the end of carriage travel, leave the diehead closed,
remove foot from the foot switch and move the REV/ -
OFF/ FOR Switch to the OFF position.
2. For Manual Chuck machines: Open the chuck and
move the carriage and workpiece to the end of the
machine. Re-chuck the rod and continue threading.
3. For Auto Chuck machines: Move the REV/OFF/FOR
Switch in the REV position and tap the foot switch to
release the workpiece. Slide the carriage and work-
piece to the end of the machine. Re-chuck the rod and
continue threading.
Left Hand Threading
Cutting left hand threads is similar to the right hand thread-
ing process. To cut left hand threads left hand threading kit,
left hand die heads and dies are required. For reaming
with the machine in reverse a Model E-863 Reamer Cone
(cat# 46660) is required.
1. For 535 Manual Chuck machines: Install the left
hand threading kit (Cat# 96517) as per the kit instruc-
tions to allow oil flow in REV. (535 Threading Machines
made prior to 2001 do not require the kit).
2. For 535 Auto Chuck machines: Install the 535
Automatic Reversing Valve Kit (Cat# 12138) as per kit
instructions to allow oil flow in REV. The kit includes a
selector for LH or RH oil flow. See Figure 24.
999-998-086.09_REV. C16

4. Threading will be done with the REV/OFF/FOR switch
in the REV position. For the Auto Chuck machines, the
chuck operation will be reversed the chuck will
close down and grip pipe in REV and open in FOR.
Removing Pipe from the Machine
1. Un-chuck the pipe.
For Manual Chuck machines: With the REV/OFF/ -
FOR Switch in OFF position and the pipe stationary,
use repeated and forceful clockwise spins of the
handwheel to loosen the pipe in the chuck. Open
the front chuck and the rear-centering device. Do not
reach into chuck or centering device.
For Auto Chuck machines: Move the REV/ OFF/ FOR
(2/0/1) Switch to the REV (2) position. Press and
release the foot switch, the machine will release the
pipe. Move the REV/OFF/FOR Switch to the OFF
(0) position.
Figure 24 – LH or RH Oil Flow Selector
Left hand threading requires the chuck jaws to grip the
pipe during REV rotation of the machine.
a. Make sure that the REV/OFF/FOR (2/0/1) switch is
in the OFF (0) position and the cord is unplugged
from the outlet.
b. Remove rear cover. Loosen cover screws and
rotate cover to remove (Figure 25A).
c. Remove E-clips and rear pivot rod support (Figure
25B).
d. Position the rear pivot rod support so that pin faces
outward and reinstall (Figure 25B).
e. Reinstall retaining E-clips and rear cover.
f. With the machine completely reassembled and
the chuck cover installed, place the REV/OFF/FOR
in the FOR position to open the chuck in prepara-
tion to left hand thread. In this configuration, the
machine can be used for both Left Hand and Right
Hand threading, depending on whether FOR or
REV is used to open the empty chuck.
g. To convert back to Right Hand threading only, turn
over the rear pivot rod support so that pin faces
inward and reinstall (Figure 25B).

Maintenance Instructions
WARNING
Make sure that the REV/OFF/FOR Switch is in the
OFF position and the machine is unplugged before
performing any maintenance or making any adjust-
ments.
Maintain threading machine according to these
procedures to reduce the risk of injury from elec-
trical shock, entanglement and other causes.
Cleaning
After each use, empty the threading chips from the chip
tray and wipe out any oil residue. Wipe oil off exposed sur-
faces, especially areas of relative motion like the car-
riage rails.
2. Firmly grip the pipe and remove from the machine.
Carefully handle the pipe as the thread may still be hot
and there may be burrs or sharp edges.
Inspecting Threads
1. After removing the pipe from the machine, clean the
thread.
2. Visually inspect thread. Threads should be smooth
and complete, with good form. If issues such as
thread tearing, waviness, thin threads, or pipe out-of
roundness are found, the thread may not seal. Refer
to the Troubleshooting Chart for help in diagnosing
these issues.
3. Inspect the size of the thread.
The preferred method of checking thread size is with
a ring gauge. There are various styles of ring
gauges, and their usage may differ from that shown
here.
Screw ring gauge onto the thread hand tight.
Look at how far the pipe end extends through the
ring gage. The end of the pipe should be flush with
the side of the gauge plus or minus one turn. If
thread does not gauge properly, cut off the thread,
adjust the die head and cut another thread. Using a
thread that does not gauge properly can cause
leaks.
Figure 27 – Checking Thread Size
If a ring gauge is not available to inspect thread size,
it is possible to use a new clean fitting representa-
tive of those used on the job to gauge thread size.
For 2" and under NPT threads, the threads should
be cut to obtain 4 to 5 turns to hand tight engage-
ment with the fitting and for BSPT it should be 3
turns.
4. See Adjusting Thread Size under Die Head Set-Up
and Use heading to adjust thread size.
5. Test the piping system in accordance with local codes
and normal practice.
Preparing Machine for Transport
1. Make sure that the REV/OFF/FOR switch is in the
OFF position and the cord is unplugged from the
outlet.

Figure 30 – Removing Chip Tray
Replace thread cutting oil when it becomes dirty or con-
taminated. To drain the oil, position a container under drain
plug at end of reservoir and remove plug. Clean build up
from the bottom of the reservoir. Use RIDGID Thread
Cutting Oil for high quality threads and maximum die life.
Reservoir in the base will hold approximately 7 qt (6,6 l) of
thread cutting oil.
The oil pump should self-prime if the system is clean. If it
does not, this indicates that the pump is worn and should be
serviced. Do not attempt to prime the pump.
Priming the Model A Oil Pump
Current 535 threading machines use self-priming pumps.
Machines made prior to June 1, 1996 have the Model A oil
pump and may require priming.
RIDGID Model 535, 500 and 500A
Thread ing Machines equipped with a Model A oil pump
should have an oil pump priming port tube extension and
a top cover access hole to allow the oil pump to be primed
without removing the top cover of the machine. This
reduces the risk of injury from contacting the internal
gearing of the machine. If your pre-1996 machine does not
have a priming port tube extension and access hole in the
top cover, we strongly recommend that they be added.
Contact Ridge Tool Technical Service Department at
rtctechservices@emerson.com, or (800) 519-3456 regard-
ing a retrofit policy.
If the jaw inserts do not grip and need to be cleaned, use
a wire brush to remove any build up of pipe scale, etc.
Top Cover Removal/Installation
The top cover is retained by fasteners at each corner. The
fasteners are secured to the cover to prevent loss. Do not
operate the threading machine with cover off.
Lubrication
On a monthly basis (or more often if needed) lubricate all
exposed moving parts (such as carriage rails, cutter wheels,
cutter feed screw, jaw inserts and pivot points) with a light
lubricating oil. Wipe off any excess oil from exposed sur-
faces.
Every 2-6 months, depending on usage, remove top cover
and use grease gun to apply Lithium based EP (Extreme
Pressure) grease to the shaft bearing grease fittings (Figure
29). Apply a small amount of grease to the exposed drive
gear teeth.
Figure 29 – Lubrication Points
Do not operate the threading machine with cover off. Always
replace cover immediately after lubricating machine.
Oil System Maintenance
Slide the chip tray out.
Keep oil filter screen clean for sufficient oil flow. Oil filter
screen is located in the bottom of oil reservoir. Loosen the
screw that secures filter to base, remove filter from oil line
and clean. Do not operate machine with oil filter screen
removed.
