 Always ground the machine to avoid electric shock or resultant death.
 Do not touch the plug with wet hands.
 Do not expose the machine to rain and water and do not use it in damp
or wet locations. Humidity will deteriorate motor insulation or lead to
electric shock.
 Immediately replace Power Plug, Power Cord or extension cord, if
damaged.
 Do not hold the Power Cord and pull it to disconnect from the receptacle
and do not put the machine on the cord and damage it.
 An extension cord used should be a three-core cabtyre cable having
an earth wire. Use a thick and durable cord for outdoor use.
 Toxic gas is generated. Do not burn the threading oil. In case
anyone should inhale the gas, move the person to a place of fresh air,
and consult a doctor without a delay.
 The Die-Head will rotate during working. Loose clothing can get easily
tangled into moving parts.

CAUTIONS IN USE
 Always use the machine at the voltage indicated on Machine Plate.
Otherwise, the machine may become hot, emit smoke or catch fire.
 Do not force the machine in a manner that the motor stops due to an
overload such as a worn Dies.
 Do not handle or use the threading oil near a fire.
 Immediately replace the Power Plug, Power Cord and extension cord, if
damaged.
 If the machine has emitted smoke or took fire, do not disassemble it
but have it inspected or repaired by a qualified person.
 Never install an earth wire to the gas pipe. If attempted, explosion may
take place.
 Do not use the machine in the presence of flammable liquids or gases
such as gasoline and thinner. Otherwise, ignition or explosion may
take place.

Explosion

 Always wear gloves when replacing Dies. Otherwise, you may cut
your hands.
 Cut surfaces are very sharp and do not touch them with your hands.
 When it is required to touch the saw blade and moving parts for
replacement, etc., switch off the machine and unplug it before starting
that operation.
 Before plugging the machine in, always make sure that the switch is
OFF. If the machine remains plugged in, it will start suddenly, leading
to unexpected accident or injury.
 During operation, keep your hands and face away from the moving
parts. You may be caught in the moving parts, causing injury.
 Do not use gloves for works such as threading.
 You may be caught in the moving parts, causing injury.
 Do not wear neckties, open-sleeved clothing, knitted gloves, loose
clothing or jewelry (such as necklaces). Otherwise, you may get caught
in moving parts.
 Wear caps or protective hair covering to contain long hair. Otherwise,
you may get caught in moving parts.
 When not in use or when servicing, cleaning, checking or replacing
parts, switch off and unplug the machine. If the machine remains
plugged in, it will start suddenly, leading to accident or injury.
 Wear safety glasses while operating the machine. Threading oil or chips
enter your eyes and nose.
 Do not blow off chips using air. They may get into your eyes and loss of
eyesight may result.
 Use a face or dust mask if operation creates dust. Sawdust and dirt
may enter your eyes and nose.

 Immediately after threading, Dies, chips and threaded surface are hot.
Do not touch them directly with hands.
 Fix Spindle Case to avoid moving while carrying the machine, hold
and lift the bottom of the machine.
 When lifting the machine, bend your knees to avoid a load on your waist.
 The machine stained with threading oil is slippery. Do not drop the
machine on your feet while lifting it.
 Do not install the machine inclined or on an unstable place. The machine
falls down, causing injury.
 Keep proper footing and balance at all times. You may tumble and get hurt.
 Do not operate the machine when you cannot concentrate on your work,
e.g. when you are tired or while under the influence of alcohol,
medication or drugs. Otherwise, accident or injury may occur.
 Before turning on the machine, make sure that hand tools used for
inspection or adjustment are removed from the machine. Accident or
injury may occur if you start the machine with hand tools on it.
 Use only the accessories and attachments given in this manual and
our catalogs. A failure to do so will lead to accident or injury.
 Die-Head is wet and slippery with threading oil. Do not drop it on your
feet while replacing.
 Immediately stop the machine if something is wrong with the machine
or you have noticed unusual smell, vibration, sound, etc. during
operation, and refer to "6. TROUBLE SHOOTING" in this manual and
follow the corresponding instructions.
 Repair should only be carried out by our sales representative. Otherwise
the machine may not show its performance or you may get injured.
Ask the shop of your purchase or our sales office.
 Our products are in accordance with the relevant safety rules. Do not
modify them.

 Do not put the machine or workpiece on Power Cord. Damaged cord
and current leakage will occur.
 Do not leave the machine with a long workpiece set on it. You may
tumble over it and get hurt.
 Securely install accessories in accordance with this manual. Otherwise,
accident or injury result.
 Before further use of the machine, a guard or other part that is damaged
should be carefully checked to determine that it will operate properly
and perform its intended function.
 When the machine is carried with threading oil in it, the oil may splash
and stain clothing due to vibration.
 If you have dropped or hit the machine accidentally, carefully check for
damage, crack or deformation. If the machine is used with such defect,
poor threading accuracy, accident and injury can result.
 Before leaving the machine for a long time, disconnect Power Plug.
 Work wet with threading oil is slippery. Do not drop it on your feet.
 It is mandatory to use Pipe Support for long and heavy workpiece.

• For proper threading, observe the following.
• Use the Die-Head and Dies which match the thread size.
• Install the Die-Head on the Spindle Case properly.
• Do not put Die-Head direct on the ground and handle it carefully.
• Make sure that the threading oil pours on the Dies.
• Avoid deformation and oblique cutting of pipes.
• Keep your work bench and area tidy and well lit. Cluttered areas and
benches invite injuries.
• Do not let visitors touch the machine and Power Cord or operate the
machine.
• When not in use, machines should be stored in dry and high or locked-
up place - out of reach of children.
• Threading Oil
•Threading oil contacting the skin may cause inflammation. Wear protective gloves
when handling the threading oil. In case it contacts your hands, completely wash
it off with water and soap.
•Do not drink the threading oil because it causes diarrhea and vomiting. If
swallowed accidentally, do not force to vomit and consult a doctor immediately.
•Keep the threading oil out of reach of children.
•Do not dilute the threading oil nor mix with other threading oil.
•When the threading oil is extremely deteriorated causing poorly finished
threads, early stage replacement with new oil is recommended.
•Avoid direct sunlight and store in a dark place. After use, close up the container
tightly to prevent dirt and water from entering.
•Do not inhale oil mist or vapor of the threading oil. It causes nausea. If inhaled
accidentally, move to a place where fresh air prevails, cover the body to keep
warm, lie quietly and consult a doctor.
•Dispose of waste oil and waste oil container as industrial waste. Do not heat the
waste container, do not drill holes into it and do not cut it. Ignition or explosion
may take place.

2) Installation
(1) Put the machine in a place free from moisture.
(2) Put the machine on a flat surface without play or on a flat work bench. In this condition, the Motor
side is higher than other parts.（fig.2）
(3) Secure a sufficient space around the machine. A wide space is necessary particularly when working
long and heavy workpiece.
(4) It is mandatory to use Pipe Support for long and heavy workpiece. Avoid excessive force applied to
the machine which causes it to tilt.
(5) Make sure that the power source is equipped with a ground fault circuit breaker to avoid electric
shock.
(6) Use an earth clip when a power receptacle without a base for grounding is used.
(7) When an extension cord is used, use the one conforming to the applicable regulations.
 Always ground the machine to avoid electric shock and resultant
death.
 An extension cord used should be a three-core cabtyre cable having
an earth wire. Use a thick and durable cable for outdoor application.
 Never install an earth on the gas pipe. Explosion may take place.
 Do not put the machine with Vise side higher than other parts.
 Do not use the machine in rain or outdoors. Die-Head or Dies will rust.
