Here are some tips:
When cutting, saw into the prefinished side first to avoid chipping the finish. Always use a carbide-tipped blade. Use blue painters tape along the area to be cut to help prevent chipping the prefinished surface.
Use a tapping block to move the hardwood into position. Do not hit the hardwood flooring directly.
Keep the installation area as clean as possible. Do all the cutting in another area.
Place tools on a piece of cardboard on top of your hardwood to avoid scratching or damaging your new floor.
Always work from your subfloor, not your new hardwood floor.
All of these tips came from the quick installation guide that I posted.
