QUICK GUIDE
Never run the engine in a closed or confined
area.
Exhaust gas contains carbon monoxide
which is poisonous to humans. Avoid inhalation
of exhaust gas.
Never touch any exhaust system parts while
engine is running.
Always allow enough time,
after stopping the unit, for proper cooling of
these parts and surrounding areas.
Refuel engine with care.
Gasoline is
extremely flammable, and gasoline vapor can
explode. Refuel in a well-ventilated area, with
the engine stopped.
Careful not to pinch your fingers.
Do not
place your fingers near the cooling fan and the
engine output shaft when the engine is running.
