Never run the engine in an enclosed or confined area. Exhaust
contains poisonous carbon monoxide gas; exposure can cause loss
of consciousness and may lead to death.
The muffler becomes very hot during operation and remains hot for
a while after stopping the engine. Be careful not to touch the
muffler while it is hot. Let the engine cool before storing the
snowblower indoors.
Stop the engine and let it cool before operating covers for
inspection and other servicing.
Carefully check the area before backing the snowblower up or while
working in reverse.
To protect your ears, use earplugs while operating the snowblower.
While operating the snowblower, hold the handle firmly and walk,
don't run. Wear suitable winter boots that resist slipping.
