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.

REPLACEMENT PLUG IS A NGK BPMR7A.

 IMPORTANT

Note that using any spark plug other than those des-
ignated may result in the engine failing to operate prop-
erly or in the engine becoming overheated and dam-
aged.

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 leak-
age is found, stop using the machine and have it re-
paired immediately.

Note that failing to do so may result in the engine
catching on fire.

ANGLE TRANSMISSION

•   The reduction gears are lubricated by multipurpose,

lithium-based grease in the angle transmission. Sup-
ply new grease every 25 hours of use or more often
depending on the job condition.

•   Remove the bolt opposit to the grease nipple before

installing new grease to arrange for old grease to exit.

INTAKE AIR COOLING VENT

 WARNING

Never touch the cylinder, muffler, or spark plugs
with your bare hands immediately after stopping
the engine.  The engine can become very hot when
in operation, and doing so could result in severe
burns.

When checking the machine to make sure that it
is okay before using it, check the area around the
muffler and remove any wood chips or leaves

brushcutter. Failing to do so could cause the muf-
fler to become overheated and that in turn could
cause the engine to catch on fire.  Always make
sure that the muffler is clean and free of wood
chips, leaves, and other waste before use.

• Check the intake air cooling vent and the area

around the cylinder cooling fins after every 25
hours of use for blockage, and remove any waste
which has attached itself to the brushcutter. Note
that it is necessary to remove the engine cover
shown in (MA5) in order to be able to view the up-
per part of the cylinder.

 IMPORTANT

If waste gets stuck and causes blockage around the
intake air cooling vent or between the cylinder fins, it
may cause the engine to overheat, and that in turn
may cause mechanical failure on the part of the
brushcutter.
