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 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.
MUFFLER
WARNING
• Inspect periodically, the muffler for loose fasteners, any damage or cor-
rosion. If any sign of exhaust leakage is found, stop using the machine
and have it repaired immediately.
• Note that failing to do so may result in the engine catch-
ing on fire.
WARNING
• Make sure that the engine has stopped and is cool before per-
forming any service to the machine. Contact with moving cutting
head or hot muffler may result in a personal injury.
AIR FILTER
• The air filter, if clogged, will reduce the engine performance.
Check and clean the filter element in warm, soapy water as
required. Dry completely before installing. If the element is
broken or shrunk, replace with a new one.
