MAINTENANCE
Clean Finger Guard Area: If your BULLDOG™ 5500
is equipped with an engine that has a finger guard,
you should clean it as often as needed, to remove dirt
or debris that may collect on the fin areas. A dirty fin-
ger guard can result in overheating and damaging the
engine. (See Figure D.2).
CLEAN COOLING SYSTEM: See Figure D.3. Clean
the internal cooling fins and surfaces to prevent over-
1
speeding, overheating, and engine damage. Clean
every 100 operating hours or as often as necessary.
