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 tool’s

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.

rotating pipe or machine parts leading to personal

injury.

• Do not use for other purposes such as drilling

holes or turning winches. Other uses or modifying this

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

prevent the machine from tipping.

• While operating the machine, stand on the side

where the operator control switch is located. Opera -

ting the machine from this side eliminates need to

reach over the machine.

• 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. This

practice will reduce the chance of entanglement in

rotating parts.

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

holes provided at each corner of the machine base. Base

hole spacing is 29.5" x 15.5" (749 mm x 394 mm). Tighten

securely.

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

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.

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 on t-

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.

Threading Speed Selection

• Up to 36 RPM – Suitable for threading up to 2" pipe,

bolt threading, high torque applications like stainless

steel and high hardness material.

• 46 RPM – Suitable for threading up to 2" pipe. High

Speed Dies are recommended.

• 54 and 58 RPM – Suitable for threading up to 1

1

/

4

" pipe.

High Speed Dies are recommended.

• Higher than 58 RPM – Not suitable for threading. Use

for cutting and reaming only.

If the machine stalls while operating, immediately release

foot switch and change to low speed. Do not change

speed while cutting, reaming or threading.

If equipped with a shifter (see Figure 18), to shift:

Figure 18 – 535 Shifter

1. Pull the shifter knob out.

2. Move the shifter to the desired speed position and

release the knob into detent.

If shifter cannot be moved, leave in current speed set-

ting. Depress and release the foot switch, allow the

machine to come to a full stop and try shifting again.

Do not shift while the machine is rotating.

400 Volt three phase 535 machines can be operated in 35

or 70 rpm. This is controlled by the machine switch, which

is marked 2-1-0-1-2. 0 is the OFF position, 1 is 35 rpm (For -

ward and Reverse), 2 is 70 rpm (Forward and Reverse).

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.

Figure 20A – Cutter Wheel Blade Against End of Pipe. Set

Pointer to Zero (0)

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

535 Manual Chuck/535 Auto Chuck Threading Machines

Figure 25B – Rear Pivot Rod Support - Pin Placement

3. Place a 5/16" pin 2" long through the holes in carriage

rest and left hand die head to retain in place (see

Figure 26).

Figure 26 – Retaining LH Die Head in Place

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).

Figure 28 – Machine prepared for Transport

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.
