WARNING
1. Be sure to turn OFF the power to the sewing machine for the sake of safety before assembling the sen-
sor amplifier components.
2. Be sure to firmly tighten the screws to prevent them from loosening by vibration when the sewing ma-
chine is in operation.
3. Jig is separately available. The gauge set (part number: 40250040) for the SD-29 should be purchased
separately.
4. Be sure to turn OFF the DPC function. (Refer to
.)
WARNING
1. Take care not to allow the direct laser light or the mirrored-surface reflected laser light to enter your
eyes.
2. The laser light irradiated from the laser has a high optical power density and therefore can cause blind-
ness when it enters the eye.
WARNING
Do not disassemble the sensor.
If the sensor is disassembled, the laser light will leak to cause impaired eyesight.
