DANGER
DO NOT
fill the fuel tank while the engine
is running or hot. In the event of a fuel
spill,
DO NOT
start the engine until all
fuel residue has been wiped up and the
area surrounding the engine is dry. Fuel
is
extremely flammable
and can ignite if
it comes into contact with hot engine parts
or sparks from the ignition system.

Engine components can generate extreme
heat. To prevent burns,
DO NOT
touch
these areas while the engine is running
or immediately after operating.

operate the engine with the muffler
removed.
NOTICE
Operating the engine without an air filter, or with a
damaged or worn air filter in need of replacement, will
allow dirt to enter the engine, causing rapid engine
wear.
