Use the correct part name from equipment list
Label only non-obvious parts,
the Equipment List should be used as the main guide
Avoid extra text to allow more visual-based instructions
Avoid text on the image where possible
See exception below
Use lines without arrowheads
Snap should be turned off to allow precise line placement
