Non-standard parts may not operate
properly with your unit and may cause
damage and lead to personal injury.
NOTE:

tion frequently. If a blade's performance
changes suddenly, stop the
engine and check the blade for cracks
or other damage. Replace a damaged
blade IMMEDIATELY!
n Check the entire unit for leaking fuel or
grease.

check the cooling fins and air cleaner
for clogging and clean them as neces-
sary.

cleaner or element is damaged, or if
the element is wet.

Before removing the spark plug, clean
the area around the plug
to prevent dirt and debris from getting
into the internal engine parts.
WARNING!
n Never repair a damaged blade
by welding, staightening, or by
modifying its shape. An altered
blade may break during opera-
tion, resulting in serious personal
injury.

cutting blades on Shindaiwa trim-
mers or brushcutters.
n Blades are not interchangeable
between Shindaiwa edgers and
trimmer/brushcutter models.

Keep the spark plug and wire connections
tight and clean.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws)
are tight.
n Carefully remove any accumulation of
dirt or debris from the muffler

areas could cause the engine overheat-
ing, induce premature wear, or create a
fire hazard.
