General Maintenance
Muffl er
This unit must never be operated with a
faulty or missing muf
fl
er. Make sure the
muf
fl
er is well secured and in good condi-
tion. A worn or damaged muf
fl
er is a
fi
re
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.
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, staightening, 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 trim-
mer/brushcutter models. Operating
any unit with a blade or attachment

engine, check the cooling
fi
ns and air
cleaner for clogging, and clean as nec-
essary.

Carefully remove any accumulations
of dirt or debris from the muf
