The bar rail should always be a square. Check for wear of the bar
rail. Apply a ruler to the bar and the outside of a cutter. If a gap is
observed between them, the rail is normal. Otherwise, the bar rail
is worn. Such a bar needs to be corrected or replaced.

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. In the State of California it is required by
law (Section 4442 of the California Public Resources Code) to equip a
spark arrester when a gas powered tool is used in any forest covered,
brush covered, or grass covered unimproved land.

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 be-
come 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 cyl-
inder 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
(MA5) 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.
