Before you begin
Make sure you have a stable, clean working environment. Dust and dirt can get into components and may
cause mal-function. Adequate lighting and proper tools can prevent you from accidentally damaging the
internal components.
Most of the electrical and mechanical connections can be disconnected by using your fingers. It is
recommended that you do not use needle-nosed pliers to disconnect connectors as these can damage the soft
metal or plastic parts of the connectors.
CAUTION
To prevent scratching the case of the machine, make sure the worktop
surface is clean and flat.
