WARNING

Make sure that the engine has stopped and is cool before performing any service to the machine. 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. 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.

IMPORTANT

•How to attach two air filter elements

2.Attach thick element so that stamp side is outside

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 replacement plug, use the correct type specified by Husqvarna.

0.6~ 0.7 mm

•REPLACEMENT PLUG IS NGK CMR7H OR CHAMPION RZ7C.

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.
