WARNING

•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)

(1) Air filter

■FUEL FILTER

•When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage. (MA2)

(1) 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.

IMPORTANT

•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.
