WARNING
• Make sure that the engine has stopped and is cool be-
fore performing any service to the machine. Contact with
moving cutting head or hot muffler may result in a per-
sonal injury.
AIR FILTER
• The air filter, if clogged, will reduce the engine performance.
Check and clean the filter element in warm, soapy water as

SPARK PLUG
• Starting failure and misfiring 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 replacement plug, use the
correct type specified by ZENOAH.
• REPLACEMENT PLUG IS A NGK CMR7A.
IMPORTANT
• Note that using any spark plug 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
WARNING
• Inspect periodically, the muffler for loose fasteners, any
damage or corrosion. If any sign of exhaust leakage is
found, stop using the machine and have it repaired im-
mediately in the repair specialty store.
• Note that failing to do so may result in the engine catch-
ing on fire.
