FUEL FILTER
• When the engine runs short of fuel supply, check the

fuel cap and the fuel filter for blockage.

SPARK PLUG
• Starting failure and mis-firing 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.

0.6~0.7mm

• REPLACEMENT PLUG IS A CHAMPION RZ7C

OR A NGK CMR7H.

WARNING

• Make sure that the engine has stopped and is cool

before performing any service to the machine. Con-
tact with moving cutting head or hot muffler may
result in a personal injury.

AIR FILTER
• The air filter, if clogged, will reduce the engine perfor-

mance. Check and clean the filter element in warm,
soapy water as required. Dry completely before in-
stalling. If the element is broken or shrunk, replace
with a new one.
