Important: The fasteners on the covers of this machine
are designed to remain on the cover after removal.
Loosen all of the fasteners on each cover a few turns
so that the cover is loose but still attached, then go
back and loosen them until the cover comes free. This
prevents you from accidentally stripping the bolts free
of the retainers.
