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

required. Dry completely before installing. If the element is

broken or shrunk, replace with a new one.

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.
