CAUTIONS FOR SAFE OPERATION
Read this INSTRUCTION MANUAL thoroughly for safety and
always follow the instructions.
Before using the Detector, read this INSTRUCTION MANUAL carefully and use the Detector
correctly and safely.
Keep this INSTRUCTION MANUAL carefully and be sure to always refer to it when necessary.
Cautions For Safety
Be very careful not to get caught in the conveyer belt, rollers and other rotating and moving parts.
Make sure to observe the following cautions.
●Working Clothes:
Do not wear a necktie, muffler, scarf or other hanging articles and be careful not to get sleeves, cuffs,
skirt and other parts of the clothes caught in the Detector.
●Cleaning the Detector:
Before checking or cleaning the belt, rollers and other rotating parts always turn off the power source
switch and pull the plug out of the receptacle.
●Grounding the Detector:
The green lead wire on the power plug is the grounding conductor. Always connect it for safety's sake
andtopreventreceivinganelectricshock.
Cautions For Use
●Only needles, pins and other articles made of iron (Ferromagnetic materials) can be detected.
Weakly magnetic articles such as those of stainless steel and non-magnetic articles can not be detected.
Always use articles made of iron
●Use metal buttons, fasteners, hooks and other garment fastenings and accessories that have been treated
previously for detection support, that is, Needle Care (NC) products. (See page 12)
●Before and after needle detecting work, always check and adjust the sensitivity of the Detector with the
attached test pieces by the specified method.
●Detection sensitivity of needles, broken needles and iron pieces differs with their size, quality, passing
height and direction. Use the Detector after surely checking with actual articles.
●A strong magnetic field is being generated from the detection unit. Clocks and watches, diskettes,
credit cards, etc. may go out of use because of the magnetic field, so be sure to keep them away from
the Detector.
This mark indicates that the text concerns matters in which there is danger of
injury and/or physical damage occurring.

１．APPLICATIONS AND FEATURES
APPLICATIONS
This Detector is for detecting needles straying in sewn garments such as women's, children's and men's clothings,
uniforms, working clothes, etc. Pay particular attention to the following points.
CAUTIONS
●Use detection support type accessories, that is, Needle Care (NC) products. (See Page 12).
●Make sure at the design stage that such garment accessories as iron and electrolytic nickel-plated articles
that react to the Detector will not be used.
●Always use iron needles and pins (ferromagnetic materials: those that will be strongly attracted to
permanent magnets) for sewing and other work. Stainless steel and other non-magnetic metals can
not be detected.
SENSITIVITY AA : Broken sewing machine needle
(Equal to broken tips of Industrial sewing machine needle No.7 to 9.)
B : Iron‑made standard marking pin (φ0.6×L33 mm)
FEATURES
A. Broken sewing machine needles and iron-made marking pins etc. can be detected by only placing sewn
garments on the conveyer belt. When any needles are detected, the conveyer belt will stop automatically.
B. It is efficient because straying needles can be inspected under the condition of only 1 sheet but also bundled
and packed sheets.
C. As the detection area is tunnel shape, the difference of the detecting sensitivity by the thickness of the objects
to bo inspected is very few.
Straying needles can be detected at each sensitivity as follows.
Sensitivity AA : Broken sewing machine needle
(Equal to broken tips of Industrial sewing machine needle No.7 to 9.)
B : Iron-made standard marking pin (φ0.6×L33 mm)
D. The sign to commence the detecting work can be recognized visually by providing with the LED while
standing by, the detector can be used simply and conveniently.

２．INSTALLATION OF THE DETECTOR
PREPARATION
1. Selection of Location・Notices
1‑1 Measures against Vibration
Choose a place indoors that has no vibration. A concrete floor gives the best results.
When the Detector has to be placed on a wooden floor, first place thick plywood, etc.
(example,10to15mmthickconcretepanels)onthefloor to prevent direct transmission of any vibration.
This usually suffices to make the Detector serviceable, although the best thing to do
would be to reinforce the wooden floor against vibration.
1‑2 Effect of Metallic Products and Machinery
There should be no metallic desks, chairs, lockers, building pillars, reinforcing bars and other metallic
objects within 1 meter from the detection unit. Also, keep air-conditioners, sewing machines, cutters,
packing machines and other moving metallic objects at least 4 meters away.
Detector may react when through near needle detecting part holding metal materials such as scissors,
stapler and so on inside a pocket of apron etc.
1‑3 Electric Wave Interference
Keep cellular phone, machines and devices that let off sparks, high-frequency wrapping machines, and other
machines that could interfere with the normal operation of the Detector asfaras10metersormoreaway.
Also avoid places near roads and rails on which cars and electric trains travel.
1‑4 Ambient Conditions
Select a place where is at normal temperature, little humidity and dust etc.
1‑5 Influence on Others
A strong magnetic field is generated from the detection unit. Clocks and watches, diskettes,
credit cards, etc. may go out of use, so be sure to keep them away from the Detector.

2. Power Source
Use a exclusive power source for the Detector.
Wire (or pipe) the power source to a 100V/220V AC receptacle equipped with
a grounding terminal. The receptacle should have a breaker that is independent
from other machines.
Always connect the green grounding terminal of the power source plug
of the Detector to the receptacle.
Dust adhered to the prongs of the power source plug could be
the cause of fire, so wipe them clean.
INSTALLATION
1. Cautions for moving the Detector
After unpacking the Detector, move it to its place of
installation with the casters provided for that purpose.
Donotpushorpullontheplasticguides
① and roller covers ② on both ends as
theyareliabletobedamaged.
2. Securing method
Adjust the nuts of the four levelling bolts with a spanner so
that the wheels of casters are clear of the floor by about 5mm
each. Refer to the right figure.
The detector may malfunction unless the four
levelling bolts are in full contact with the floor.
3. Cleaning
As small pieces of metal may be sticking to the surface and/or reverse side of the belt, joints and rollers as a
result of handling and transporting the Detector, clean those parts carefully with a vacuum cleaner and
a clean piece of cloth.
For safety's sake, be sure to unplug the Detector when doing the cleaning.

4. Adjusting Level
The conveyer belt has been adjusted for tension and meander on a level floor before the detector is shipped.
Therefore, if the belt meanders to one side, the cause is that the floor is inclined or that the levelling bolts
have been improperly adjusted, so adjust those as follows.
＊Note that adjusting may take many attempts and several hours to accomplish.
4‑1 Gradually raise the two levelling bolts on the guide side
to which the belt has shifted or lower the levelling bolts
on the opposite side. (See 2. Securing Method on Page 5)
4‑2 As this adjustment can mostly be done with these four
levelling bolts, go about the job patiently.
4‑3 When adjustment by the above procedure is difficult,
adjust by turning clockwise a little at a time the tension
adjusting bolt on the side to which the belt shifts.
5. Confirming workings of the control unit
If the conveyer belt travels properly, carry out the following checks.
5‑1 Change the sensitivity push button switch on the control panel to AA, turn the sensitivity adjusting knob to
7to ▲ mark (8), and then make the conveyer belt travel by pressing the power source key and the
conveyer key ON.
5‑2 Walk around the Detector checking how the detection level LED go on to see how much vibration there is.
※If all the detection level LED go on, the buzzer sounds and the conveyer belt stops, it means there is too
much vibration from the floor, so reinforce the floor.
(See1-1onPage4)
6. Confirming workings of the emergency stop buttons (Option)
Emergency stop buttons are located at the entrance and at the exit of the conveyer. Check their operation.
6‑1 Press either one and, all power sources are shut off.
6‑2 When make the Detector restart, press the emergency
stop button once again and press the power source key
on the control panel.

PRINCIPLE
When a ferromagnetic substance such as needle,
iron piece, etc. moves in a static magnetic field,
a little electromotive force generates in a coil.
This electromotive force is amplified, converted
to sound and light and advise us the existence of
the substances.
