Zenoah BC3401DL - Manual (Page 23)

■ 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 4).
• 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.
WARNING
IMPORTANT
• 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.
