■ INTAKE AIR COOLING VENT
• 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 machine. 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 machine. Note
that it is necessary to remove the
engine cover shown in (MA7) in order
to be able to view the upper part of the
cylinder.
• If waste gets stuck and causes
blockage around the intake air cooling
