WARNING!
Never operate this unit with a
damaged or missing muffler or spark
arrester! Operating with missing or
damaged exhaust components is a fire
hazard, and may also damage your
hearing.
Hard starting or a gradual loss of
performance may be caused by carbon
deposits lodged in the muffler's
spark arrester screen. In such cases,
performance can usually be restored by
removing the spark arrester screen and
giving it a thorough cleaning with a stiff
bristle brush.
 Carefully remove any accumulations of
dirt or debris from the muffler and fuel
tank. Dirt buildup in these areas can
lead to engine overheating, premature
wear or fire.
CAUTION!
Do not operate the unit if the air
cleaner or element is damaged, or if
the element is wet.
