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.
Spark Plug
Keep the spark plug and wire connections
tight and clean.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
Daily Maintenance
Prior to each work day, perform the following:
NOTE:
Using non-standard replacement parts could
invalidate your Shindaiwa warranty.
 Remove dirt or debris from the engine,
check the cooling fins and air cleaner for
clogging and clean them as necessary.
 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.
 Check for loose or missing screws or
components. Make sure the cutting
attachment is securely fastened.
 Check the entire unit for leaking fuel
or grease.
 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.
 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.
