WARNING
Make sure that the engine has stopped and is cool
before performing any service to the machine. Con-
tact with moving cutting head or hot muffler may re-
sult in a personal injury.
AIR FILTER
• The air filter, if clogged, will reduce the engine perfor-
mance. Check and clean the filter element in warm,
soapy water as required. Dry completely before in-
stalling. If the element is broken or shrunk, replace
with a new one.
FUEL FILTER
• When the engine runs short of fuel supply, check the
fuel cap and the fuel filter for blockage.s
SPARK PLUG
• Starting failure and mis-firing are often caused by a
fouled spark plug. Clean the spark plug and check
that the plug gap is in the correct range. For a re-
placement plug, use the correct type specified by
ZENOAH.
• REPLACEMENT PLUG IS A NGK CMR7A.

properly or in the engine becoming overheated and
damaged.
• To install the spark plug, first turn the plug until it is

MUFFLER
WARNING
• Inspect periodically, the muffler for loose fasten-
ers, any damage or corrosion. If any sign of ex-
haust 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
• The muffler is equipped with a spark arrester to pre-
vent red hot carbon from flying out of the exhaust out-
let. Periodically inspect and clean as necessary with
a wire brush.
