tenance, repair, 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.
WARNING!

cutting attachment, or replacement
parts may not operate properly with
your unit and may cause damage and
lead to personal injury.
Prior to each work day, perform the
following:
Remove all dirt and debris from the
Ŷ
engine, check the cooling fins and
air cleaner for clogging, and clean as
necessary.
Clean any debris or dirt from the cut-
Ŷ
ting attachment.
Check the entire unit for leaking fuel or
Ŷ
grease.
Check for loose or missing screws or
Ŷ
components. Make sure the cutter
attachment is securely fastened.
Make sure nuts, bolts, and screws
Ŷ
(except carburetor idle speed adjusting
screws) are tight.
Carefully remove any accumulations of
Ŷ
dirt or debris from the muffler and fuel
tank. Check cooling air intake area at
base of crankcase. Remove all debris.
Dirt build-up in these areas can lead to

Air Filter
The C4 engine that powers your
Shindaiwa model is a hybrid 4-stroke
engine. As a hybrid, the engine is lubri-
cated by oil mixed with the gasoline
and air from the carburetor that moves
through and around the internal parts of
the engine in a similar way that a 2-stroke
engine is lubricated. Without the heavy
duty 2-stage air filter equipped on all C4
engines, dust and dirt could also move
through the engine, decreasing engine
life, increasing valve wear and the need
for more frequent valve adjustments. To
keep your C4 engine strong and reliable,
Shindaiwa recommends that you check
and service the air filter as instructed in
the 10-Hour Maintenance section that
follows.
0XIÁHU
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.
General Maintenance
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
Ŷ
welding, straightening, or by modify-
ing its shape. An altered blade may
break during operation, resulting in
serious personal injury.
Blades are not interchangeable
Ŷ
between Shindaiwa edgers and
unit/brushcutter models. Oper-
ating any unit with a blade or
attachment not approved for that
unit can be hazardous and may
cause serious injury.
