the mower belt if you detect any of these signs.

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

then go back and loosen them until the cover
comes free. This will prevent you from accidentally
stripping the bolts free of the retainers.
