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.
