Disassembly
Do not touch the board with your bare hands or metal objects, this can create a short circuit or cause an
electrical shock. Take extra care when handling boards containing sensors, motors or lamps as they may get
hot.
Take care when fitting, or removing, screws. Check for hidden screws. Always ensure that the correct screw
is used. When toothed washers are removed, ensure they are refitted in their original positions
