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

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

installing new grease to arrange for old
grease to exit. (MA6)
• When removing and installing the
holder(A), use care not to allow any dirt
and dust entering in to the gear case.
