• This engine was designed and manufactured for
specific applications. Do not attempt to modify the
equipment or use it for any application for which
it was not designed.
• Engine exhaust gases contain DEADLY carbon mon-
oxide gas. This dangerous gas, if breathed in suffi-
cient concentrations, can cause unconsciousness or
even death. Operate this equipment only in the open
air where adequate ventilation is available.
• Do not insert any object through the cooling slots
of the engine. This could damage the equipment or
injure yourself.
• Do not operate the engine faster than the speed neces-
sary to operate the equipment. Do not run the engine
at high speed when not operating the equipment.
• This engine requires an adequate flow of cooling
air for its continued proper operation. Never oper-
ate the equipment inside any room or enclosure
where the free flow of cooling air into and out of
the equipment might be obstructed. Without suffi-
cient cooling air flow, the engine quickly overheats,
damaging the engine or nearby property.

fuel or oil spills immediately. Never leave oily or
fuel soaked rags around the engine. Keep the area
around the engine clean and free of debris.
