Assembly required. These words strike fear in my heart! I have had so many disasters. I bought a table that needed to have the legs screwed on, and made a hole right through the table in attempting the task, even though I had called the neighbours in to show me how to do it.
The treadmill manual is mainly assembly instructions and looks horrendously difficult. We were so pleased the one we bought was already set up and ready for use.
I'm not at all a Do-It-Yourself man. The only time I would use the phrase is if I was asked to do one of those handyman tasks and it would be a retort, I can tell you!
