CAUTION!
Never allow dirt or debris to enter the cylinder bore! Before remov-

ing the spark plug, thoroughly clean the spark plug and cylinder head 

area!  Allow the engine to cool before servicing the spark plug! Cylinder 

threads can be damaged by tightening or loosening the spark plug while 

the engine is hot!

1.  Use the spark plug wrench to remove the spark plug. See Figure 14.
2.  Clean and adjust the spark plug gap  

to 0.6mm (0.024 in.). If the plug must be replaced, use a NGK CMR5H 

or equivalent type plug of the correct  

heat range.

3.  Install the spark plug finger-tight in the cylinder head, then tighten it 

firmly with the spark plug wrench. If a torque wrench is available, torque 

the spark plug to 16.7-18.6 Nm (148-165 inch-pounds)

CAUTION!
The engine is cooled by air drawn into the air intake cover on the blower 

housing. The blower fan then pushes the cooling air through an opening in 

the fan housing, forcing it past the cylinder cooling fins. Failure to keep the 

cooling system and its passages clear of debris will likely result in engine 

overheating, a major cause of serious engine problems that can lead to 

failure.

•   Remove all dirt and debris from blower exterior and the engine. Check the 

cooling fins and air cleaner for clogging and clean as necessary.

1.  Remove engine cover.
2.  Clean cylinder fins to allow cooling air to pass freely.

•   Carefully remove any accumulations of dirt or debris from the muffler and 

fuel tank. Dirt build-up in these areas can lead to engine overheating, fire 

or premature wear.
