Safety Precautions; Table Of Tightening Torque - Brother LX-200 Service Manual

4.1 Safety Precautions

When conducting reassembly operations, place the unit on a grounded anti-static
sheet. LSI and other electronic components are sensitive to static electricity and
may be damaged if touched while charged.
Before transporting a circuit board, wrap it in a conducting sheet such as aluminum
foil.
When using a soldering iron or other heat-producing tool, ensure that heat does not
damage wires, circuit boards, or plastic parts such as covers.
Take care not to lose small screws or washers removed when replacing parts.
Tighten all screws to the torque specified in the table below.
