Lead-free solder contains more tin, and the end of the
soldering bit may be easily corroded. Make sure to turn
on and off the power of the bit as required. If a different
Pin 1type of solder stays on the tip of the soldering bit, it is
alloyed with lead-free solder. Clean the bit after every
use of it.
When the tip of the soldering bit is blackened during
use, file it with steel wool or fine sandpaper.
Instructions for Connectors
Be careful when replacing parts with polarity indication
1. When you connect or disconnect the FFC (Flexibleon the PWB silk.
Foil Connector) cable, be sure to first disconnect the
AC cord.

2. FFC (Flexible Foil Connector) cable should be in-
serted parallel into the connector, not at an angle.
