• Note that failing to do so may result in
the engine catching on fire.
■ 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.
■ GEAR CASE
• The reduction gears are lubricated by
multipurpose, lithium-based grease in the
gear case. Supply new grease every 50
hours of use or more often depending on
the job condition.
■ FUEL FILTER
• When the engine runs short of fuel supply,
check the fuel cap and the fuel filter for
blockage.
■ SPARK PLUG
• Starting failure and mis-firing are often
caused by a fouled spark plug. Periodically
clean the spark plug and check that the
spark gap is in the correct range. For a
replacement plug, use the correct type
specified by RedMax(See SPECIFI-
CATIONS on the page 18).
• REPLACEMENT PLUG IS A CHAMPION
RCJ6Y OR THE EQUIVALENT, SUCH AS
BOSCH WSR8E OR NGK BPMR7A.
• Note that using any spark plugs other than
those designated may result in the engine
failing to operate properly or in the engine
becoming overheated and damaged.
• To install the spark plug, first turn the plug
until it is finger tight, then tighten it a
quarter turn more with a socket wrench.
■ MUFFLER
• Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any
sign of exhaust leakage is found, do not
use the brushcutter and have it repaired
immediately.
