Daily maintenance
Prior to each work day, perform the
following:
Remove all dirt and debris from the
engine, check the cooling fins and
air cleaner for clogging, and clean as
necessary.
Carefully remove any accumulations
of 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 engine overheating, fire,
or premature wear.
WARNING!
Always wear gloves when
working around the cutter assembly.
Lubricate the blades before use and
after refueling. Check the cutters for
damage or incorrect adjustment.
Clean any debris or dirt from the cut-
ting attachment.
WARNING!
Before performing any mainte-
nance, 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.
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.
Cooling
Check for loose or missing screws or
components. Make sure the cutter
attachment is securely fastened.
Check the entire unit for leaking fuel
or grease.
WARNING!
Non-standard accessories, cut-
ting attachment, or replacement parts
may not operate properly with your unit
and may cause damage and lead to
personal injury.
Air Filter
The C4 engine that powers your Shindaiwa
model is a hybrid 4-stroke engine. As a
hybrid, the engine is lubricated 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 Mainte-
nance section that follows.
Cooling
Make sure nuts, bolts, and screws
(except carburetor idle speed adjusting
screws) are tight.
