extremely dusty or dirty conditions), remove the
blower housing and other cooling shrouds. *Clean the
cooling fins and external surfaces as necessary. Make
sure the cooling shrouds are reinstalled.

screen, dirty or plugged cooling fins, and/or
cooling shrouds removed, will cause engine
damage due to overheating.
