WARNING
•
Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust
leakage is found, stop using the machine and have it
repaired immediately.
•
Note that failing to do so may result in the
engine catching on fire.
SPARK ARRESTER
•
The muffler is equipped with a spark arrester to
prevent red hot carbon from flying out of the exhaust
outlet. Periodically inspect and clean as necessary
with a wire brush.
(1)Spark arrester
GEAR CASE
•
The reduction gears are lubricated by multipurpose,
lithium-based grease in the gear case. Supply
new grease every 25 hours of use or more often
depending on the job condition.
•
Remove the bolt opposite to the grease nipple
before installing new grease to arrange for old
grease to exit.
INTAKE AIR COOLING VENT
WARNING
•
Never touch the cylinder, muffler, or spark
plugs with your bare hands immediately after
stopping the engine. The engine can become
very hot when in operation, and doing so could
result in severe burns.
•
When checking the machine to make sure
that it is okay before using it, check the area
around the muffler and remove any wood chips
or leaves which have attached themselves to
the brushcutter. Failing to do so could cause
the muffler to become overheated and that in
turn could cause the engine to catch on fire.
Always make sure that the muffler is clean and
free of wood chips, leaves, and other waste
before use.
•
Check the intake air cooling vent and the
area around the cylinder cooling fins after
every 25 hours of use for blockage, and
remove any waste which has attached itself
to the brushcutter. Note that it is necessary to
remove the engine cover shown in order to be
able to view the upper part of the cylinder.
IMPORTANT
•
If waste gets stuck and causes blockage around the
intake air cooling vent or between the cylinder fins,
it may cause the engine to overheat, and that in turn
may cause mechanical failure on the part of the
brushcutter.
