9. Maintenance
■ GEAR CASE
• The reduction gears are lubricated by
MA6
multipurpose, lithium-based grease in
the gear case. At every 25 hours of
use, supply the gear case with new
grease. (MA6)
• Remove the drive disk before installing
new grease to arrange for old grease to
exit. (MA7)
• When removing and installing the drive
disk, use care not to allow any dirt and
dust entering in to the gear case. (MA7)
■ BLADE (MA7)
• Place the blade between drive disk and
support flange while locking the gear

shaft by putting the allen key, through
the key holes on the drive disk and the
gearcase. Use the socket to tighten the
locking screw.

■ 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

WARNING
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 (MA8) in order
to be able to view the upper part of the
cylinder.
MA8 • 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 machine. (MA8)
