Precautions for Use
1. Pass a sample of the needle and iron pieces to be detected before use through the machine and
check that the belt stops before starting work.
2. The material that can be detected is limited to steel.
Since stainless steel needles and marking pins cannot be detected, be sure to use iron.
3.For metal sewing accessories such as buttons, slide fasteners, and lock hocks, please designate
those labeled as "Needle detector-compliant" at the stage of design and specifications.
4. The metal objects worn by the operator must be removed because the machine reacts with the
moving metal objects.
Precautions for Installation
1. Install the machine in a horizontal position without vibration.
Secure the body horizontally with the four adjuster bolts on the main unit.
(If it’s not level, the conveyor belt might warp.)
3. Do not install the machine in the vicinity of a steel workbench or shelf.
4. Do not install the machine near the other machine that generates the magnetic field.
Machines using electromagnetic clutch motors, sewing machines, cutting machines,
packing machines, air conditioners, or inverters may cause electric or magnetic disturbance and
cause malfunction.
5. Keep away from large moving metal bodies such as railways and automobiles.
6. Separate as far as possible from the reinforcement or steel frame of the building, and
change the direction of the main body so that it can be installed in a place where no malfunction
occurs.
7. The needle detector generates magnetism.
Please note that the contents may change when magnetic cards such as credit cards are brought
closer.
8. Install the machine in a location within ambient temperature of 10°C to 40°C (non-condensing).
9. A needle detector may not be able to perform properly in a place where the installation
environment is bad.
Select the appropriate location by performing an environmental level test.
