MOTOR-OPERATED ELECTRIC TOOLS –
Part 2-12: Particular requirements for threading machines
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

safety instructions.

They shall be written in the official language(s) of the country in which the tool is sold. They

shall be legible and contrast with the background.

They shall include the name and address of the manufacturer or supplier of branded product.

7.13.101 Safety warnings

The safety warnings specified in 7.13.101.1 and 7.13.101.2, if in English, shall be verbatim

and in the exact order as given and in any other official language to be equivalent.

Format of all safety warnings must differentiate, by font, highlighting or similar means, the

context of the clauses as illustrated below.

All notes in the safety warnings are not to be printed, they are information for the designer of

the manual.
7.13.101.1 General Power Tool Safety Warnings

WARNING Read all safety warnings and all instructions. Failure to follow the warnings

and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
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
---------------------- Page: 7 ----------------------
– 6 – 61029-2-12 © IEC:2010
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 tools 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 or there is the

likelihood of cutting into the cord, 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 medication. 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 hearing 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 tools with your finger on the switch or energising power tools that have

the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench

or a key left attached to a rotating part of the power 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.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and
clothing 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.
4) 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 power

tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
---------------------- Page: 8 ----------------------
61029-2-12 © IEC:2010 – 7 –
e) 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.

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.

h) Keep handles dry, clean and free from oil and grease. Slippery handles do not

allow for safe handling and control of the tool in unexpected situations.
5) Service

a) 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.

7.13.101.2 Threading machine safety warnings
Work area safety

• Keep floor dry and free of slippery materials such as oil. Slippery floors invite

accidents.
• Restrict access or barricade the area when work piece extends beyond machine
to provide a minimum of one metre clearance from the work piece. Restricting

access or barricading the work area around the work piece will reduce the risk of

entanglement.
Electrical safety

• Keep all electric connections dry and off the ground. Do not touch plugs or tool

with wet hands. These precautions will reduce the risk of electrical shock.
Personal safety
• Do not wear gloves or loose clothing when operating 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.
Machine 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
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 machine tipping.
• While operating the machine, stand on the side where the
REVERSE/OFF/FORWARD or FORWARD/REVERSE switch is located. Operating
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.

• Do not use this machine to install or remove fittings, it is not the intended use of

the machine. This practice could lead to trapping, entanglement and loss of control.

NOTE The terms “install” or “remove” may be substituted by regional terms.
---------------------- Page: 9 ----------------------
– 8 – 61029-2-12 © IEC:2010
• Keep covers in place. Do not operate the machine with covers removed. Exposing
moving parts increases the probability of entanglement.
Footswitch safety

• Do not use this machine if the footswitch is broken or missing. Footswitch is a

safety device that provides better control by letting you shut off the motor in various

emergency situations by removing your foot from the switch. For example: if clothing

should become caught in the machine, the high torque will continue pulling you into

the machine. The clothing itself can bind around your arm or other body parts with

enough force to crush or break bones.

7.13.102 If the safety instructions are separate from the instruction manual, then the

following warnings shall be included in the instruction manual. These warnings, if in English,

shall be verbatim and in any other official language to be equivalent.
WARNING Read all safety warnings and all instructions. Failure to follow the

warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.
