Remove contents from box. Remove the foam separators that protect the components from damage during shipping. 
Inspect the contents of the box for scratches in the paint, dents or kinked cables that may have occurred during 
shipping. Because the Dirt Rocket or the MX500 was 95 percent assembled and packed at the factory, there should not 
be any problems, even if the box has a few scars or dents.
