■ 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
stick edgers. Failing to do so could cause the
muffler to become overheated, and that this 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 stick edgers. Note that it is
necessary to remove the engine cover shown in
(MA8) 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 stick
edgers. (MA8)
