Checking the Spark Plug
Important:
Do not clean the spark plug(s).
Always replace the spark plug(s) when it has: a
black coating, worn electrodes, an oily film, or
cracks.
Note:
If you see light brown or gray on the insulator,
the engine is operating properly. A black coating on
the insulator usually means the air cleaner is dirty.
Set the gap to 0.76 mm (0.03 inch).

Installing the Spark Plug
Important:
Ensure that the spark plug is
tightened to the correct torque specification. A
loose spark plug may cause the cylinder head to
overheat, while an overtightened spark plug may
cause damage to the threads in the cylinder head.
Cleaning the Blower
Housing
Every 100 hours/Yearly (whichever comes first)
To ensure proper cooling, ensure that the grass
screen, cooling fins, and other external surfaces of the

Ensure that the cooling shrouds are installed.
Important:
Operating the engine with a blocked
grass screen, dirty or plugged cooling fins, and/or
cooling shrouds removed causes engine damage
due to overheating.
