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

invalidate your Shindaiwa warranty.
Muffler
This unit must never be operated with a
faulty or missing spark arrester or muf-
fler. 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.

tight and clean.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
Check the entire unit for leaking fuel or
grease.
Remove dirt or debris from the engine,
check the cooling fins and air cleaner for
clogging and clean them as necessary.

cleaner or element is damaged, or if
the element is wet.
CAUTION!
Before removing the spark plug, clean
the area around the plug to prevent dirt
and debris from getting into the internal
engine parts.
Blades
Keep blades sharp and check blade
condition frequently. If a blade's perfor-
mance changes suddenly, stop the engine
and check the blade for cracks or other
damage. Replace a damaged blade
IMMEDIATELY!
WARNING!
Never repair a damaged blade by
welding, straightening, or by modify-
ing its shape. An altered blade may
break during operation, resulting in
serious personal injury.
DO NOT use 2-tooth or non-
Shindaiwa approved 4-tooth cutting
blades on Shindaiwa trimmers or
brushcutters.
Blades are not interchangeable
between Shindaiwa edgers and
trimmer/brushcutter models.Operat-
ing any unit with a blade or attach-
ment not approved for that unit
can be hazardous and may cause
serious injury.
Carefully remove any accumulation of
dirt or debris from the muffler or the
fuel tank. Dirt build-up in these areas
could cause engine overheating, induce
premature wear, or create a fire hazard.
Remove and clean
or replace the element.
