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 re-
placement plug, use the correct type specified by
ZENOAH.
0.6 - 0.7 mm
• REPLACEMENT PLUG IS A NGK CMR7H.
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.
TIGHTENING TORQuE:

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 in the repair
specialty store.
• Note that failing to do so may result in the engine
catching on fire.
