Should I unpack breastpump before baby arrives?

aSearch4Me

So I am planning on breastfeeding, but will be pumping as well (to have the option of bottle feeding, so my husband can participate in feeds starting at 3-4 weeks, for a supply if someone babysits her, etc).

I've had my pump since around week 33 (Medela PISA), but it's still sealed in the box. I'm now wondering if I should go ahead, open it, clean/sterilize equipment, make sure the motor runs, etc before baby gets here? OR, should I just wait until closer to the time I plan on actually beginning to pump? Thoughts, anyone?
