 WARNING: 

Make sure that the engine has stopped and cooled down before performing any ser-

vice to the machine. Contact with moving cutting head or hot muffler may result in a personal injury. 
 

Air filter (MA1) 
 

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 ele-
ment is broken or shrunk, replace with a new one (MA1).

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

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 replacement plug, use 
the correct type. REPLACEMENT PLUG IS LD L8RTF! 

 

 

 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,
