General Power Tool Safety Warnings
Read and understand all instructions. Failure to follow all warnings and instructions may
result in electric shock, fire, and/or serious injury.

3
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.
1) Work area safety
a)Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b)Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to
lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce
risk of electric shock.
b)Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tool to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
d)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.
e)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 electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device(RCD)
protected supply. Use of an RCD reduces the risk of electric shock.
NOTE The term” residual current device (RCD) may be replaced by the term “ground fault circuit
interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”
3) Personal safety
a)Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol, or medications. A
moment of inattention while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as
dust mask, non-skid safety shoes, hard hat, or heating protection used for appropriate conditions will
reduce personal injuries.
c) 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 tool with your finger on the
switch or energizing power tools that have the switch on invites accidents.
d) Remove adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the tool may result in personal injury.
e)Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.

4
f)Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewellery, or long hair can be caught in moving parts.
g)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.
Power tool use and care
a)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 was designed.
b)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.
c) Disconnect the plug from the power source and/or the battery pack from the power tool
before making any adjustments, changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the tool accidentally.
d)Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power or these instructions to operate the power tool. Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools with care. 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.
f)Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
g) 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 different from those intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of power tool is maintained.

Power Drive Safety
• 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 machine for other applications may increase the
risk of serious injury.
• When threading 3/4" or larger pipe, use support device to resist threading forces. Use an
appropriate support device per these instructions. Support devices improve control and reduce the risk of
striking, crushing, and/or other injuries.
• When using a support device other than the supplied support arm, the support device must react
against the gear housing or fan housing. Support devices contacting the motor housing or handle may
damage these parts or increase the risk of injury.
• Always firmly hold the power drive when threading or backing die head off the pipe to resist
threading forces, regardless of support device use. This will reduce the risk of striking, crushing and
other injuries.
• Do not use this power drive if ON/OFF switch is broken. This switch is a safety device that lets you
shut off the motor by releasing the switch.
• Do not wear gloves or loose clothing when operating machines. 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.
• One person must control the work process and machine operation. Only the operator should be in
the work area when the machine is running. This helps reduce the risk of injury.
• Do not use dull or damaged dies. Sharp cutting tools require less torque and the power drive is easier
to control.
• Keep handles dry and clean; free from oil and grease. Allows for better control of tool.
• Keep floors dry and free of slippery materials such as oil. Slippery floors invite accidents.
• Only use our Hongli die heads with the Power Drives Other die heads may not fit correctly in the
power drive increasing the risk of equipment damage and personal injury.

Pre-Operation Inspection
Before each use, inspect power drive and correct any problems to reduce the risk of serious
injury from electric shock, crushing injuries and other causes and prevent power drive damage.
1. Make sure that the power drive is unplugged.
2. Inspect the power cord and plug for damage. If the plug has been modified or if the cord is damaged,
do not use the Threader until the cord has been replaced.
3. Inspect the Threader for any broken, missing, misaligned or binding parts as well as any other
conditions which may affect the safe and normal operation of the tool. If any of these conditions are
present, do not use the Threader until any problem has been repaired.
4. Use tools and accessories that are designed for your Threader and meet the needs of your application.
The correct tools and accessories allow you to do the job successfully and safely. Accessories suitable for
use with other equipment may be hazardous when used with this Threader.
5. Clean any oil, grease or dirt from all equipment handles and controls. This reduces the risk of injury due
to a tool or control slipping from your grip.
6. Inspect the cutting edges of your dies. If necessary, have them replaced prior to using the Threader.
Dull or damaged dies can lead to binding and poor quality threads.
7. Check the level and quality of the thread cutting oil. Replace or add oil if necessary.
NOTE! Thread cutting oil lubricates and cools the threads during the threading operation. A dirty
or poor grade cutting oil can result in poor thread quality.
Operating Instructions
Installation of Adapter
Adapter is required for 1/2″through 11/4″11-R Die Heads. Push Adapter into threader and tighten the ring
at opposite side (Figure 1 & 2). Installation can be made from only one side of the threader.
Fig 1 Fig 2

10
Threading with 11R Die Heads
1. For 11/2″- 2″11-R Die Heads, push die heads, spline end first, squarely into the threader until the
spring engages securely. For 1/2″- 11/4″11R Die Heads, rotate adapter cap clockwise, then push die
heads into adapter spline end first, then release the adapter cap to hold die head (fig 3 & 4).
NOTE! Installation can be made from only one side of the threader.
Fig3 Fig4
2. If possible, secure the pipe in a portable tristand vise or a bench vise.
To prevent tipping, long lengths of pipe should also be supported with pipe stand.
3. Be sure the Oiler is properly filled with Thread Cutting Oil. We suggest specific oiler for this purpose.
4. Position Support Arm on pipe so end of support arm is in line with end of the pipe (Figures 5). Make
sure jaws squarely contact pipe and tighten handle firmly to prevent slipping of the jaws.
Note! To avoid serious injury from losing control of the threader, a support arm should be used
when threading 3/4″or larger pipe.
When threading pipe less than 3/4″in size without a support arm, hold onto the threader firmly
with one hand to exert pressure against the handle forces developed during threading.
5. Place Die Head over end of pipe and insert post of support arm through notch in gear case.
6. Simultaneously actuate the ON/OFF switch and exert pressure against the Die Head with the palm of
free hand to assist in starting thread. Apply plenty of thread cutting oil to the dies during threading. This
will reduce the torque required to thread and improve the thread quality (Figure 6).

7.Keep ON/OFF switch depressed until end of the pipe is even with edge of the dies. Release the switch
button.
8. Back off the Die Head from the threaded pipe, reversing the directional switch and actuating the
ON/OFF switch.
Note! Hold onto the threader handle firmly to resist handle forces developed while backing off the
Die Head.
9.When dies clear the end of the pipe, grip the handle on top of the threader and remove the threader and
Die Head from the pipe.
10. Remove the support arm from the pipe.
Note! To avoid injury, make sure long sections of pipe are supported at the end farthest away from
the vise prior to removal.
Inspecting Threads
1. Remove any oil, chips or debris from the thread.
2. Visually inspect thread. Threads should be smooth and complete, with good form. If issues such as
thread tearing, thin threads, or pipe out-of-roundness are observed, the thread may not seal when made
up. 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 in Figure 7.
•Screw ring gauge onto the thread hand tight.
•Look at how far the pipe end extends through the ring gauge. 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.
Fig 7
• If a ring gauge is not available to inspect thread size, it is possible to use a new clean fitting
representative 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 engagement with the fitting and for 2" and under BSPT
threads it should be 3 turns.
Maintenance Instructions
Make sure machine is unplugged from power source before performing maintenance or making

12
any adjustments.
Cleaning
1. After each use, empty the threading chips from the 418 Oiler (if used) chip tray and wipe out any oil
residue.
2. Wipe off any oil, grease, chips or dirt from the power drive, including the handles and controls. Clean
the SQ30-2B retaining mechanism.
3. Wipe off any oil, grease or dirt from the support arm. If required, clean the support arm jaws with a wire
brush.
4. Remove chips and dirt from die heads.
Changing Dies in 11-R Die Heads
A variety of dies are available for installation in 11- R Die Heads.
See catalog for availability.
1. Remove the four screws from cover and remove the cover plate.
2. Remove the worn dies from the die head.
3. Insert new dies into slots – numbered edge up.
Numbers on the dies must correspond with those on the die head slots. Always replace dies as a set.
Fig8
4. Replace the cover plate and tighten the four screws lightly.
5. Place die head on already threaded pipe until dies begin to thread. This forces stop on dies outward
against lugs on cover plate and properly sets the size.
6. Tighten the four screws securely. Remove the threaded pipe and make a test cut.
Motor Brush Replacement
Check motor brushes every 6 months and replace brushes when they are worn to less than 1/4″.
Machine Storage
Motor-driven equipment must be kept indoors or well covered in rainy weather. Store the threader in a
locked area that is out of reach of children and people unfamiliar with threader. This power tool can cause
serious injury in the hands of untrained users.
