General Maintenance
Mufer
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 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.
n
Remove dirt or debris from the engine,
check the cooling fins and air cleaner for
clogging and clean them as necessary.
n 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.
n Check for loose or missing screws or
components. Make sure the cutting at-
tachment is securely fastened.
n Check the entire unit for leaking fuel or
grease.
Blades
Keep blades sharp and check blade condi-
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!
WARNING!
n 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.
n
Blades are not interchangeable
between Shindaiwa edgers and trim-
mer/brushcutter models.
Operating
any unit with a blade or attachment not
approved for that unit can be hazardous
and may cause serious injury.
WARNING!
Before performing any maintenance, re-
pair or cleaning work on the unit, make
sure the engine and cutting attachment
are completely stopped. Disconnect
the spark plug wire before performing
service or maintenance work
.
