English
• Make sure that the engine has stopped and is
cool before performing any service to the
brushcutter. 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. Monthly 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. (MA1)

FUEL FILTER

SPARK PLUG
• Starting failure and mis-firing are often caused by a
fouled spark plug. Periodically clean the spark plug
and check that the spark gap is in the correct range.
For a replacement plug, use the correct type
specified by RedMax/ZENOAH(See SPECIFI-
CATIONS on the page 4). (MA3)
• When you take off the spark plug, twist (1) and pull
off the cap (2). (MA4)
• REPLACEMENT PLUG IS A NGK BPMR7A.
• Note that using any spark plugs 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.
