Muffler
This unit must never be operated with
a faulty or missing spark arrester or
muffler. Make sure the muffler is well
secured and in good condition. A worn
or damaged muffler is a fire hazard and
may also cause hearing loss.
Spark Plug
Keep the spark plug and wire connec-
tions tight and clean.
Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws)
are tight.
Blades
Keep blades sharp and check blade
condition frequently. If a blade’s per-
formance changes suddenly, stop the
engine and check the blade for cracks
or other damage. Replace a damaged
blade IMMEDIATELY!
■
Never repair a damaged blade
by welding, straightening, or by
modifying its shape. An altered
blade may break during opera-
tion, resulting in serious personal
injury.
■
DO NOT use 2-tooth or NON-
Shindaiwa approved 4-tooth cut-
ting blades on Shindaiwa trim-
mers or brushcutters.
■
Blades are not interchangeable
between Shindaiwa edgers and
trimmer/brushcutter models.
Operating any unit with a blade
or attachment not approved for
that unit can be hazardous and
may cause serious injury.
WARNING!

Using non-standard replacement
parts could invalidate your Shindaiwa
warranty.
