Servicing the Spark Plug
Service Interval: Every 100 hours
Ensure that the air gap between the center and side
electrodes is correct before installing the spark plug.
Use a spark plug wrench for removing and installing
the spark plug and a gapping tool or feeler gauge to
check and adjust the air gap. Install a new spark plug
if necessary.
Type of Spark Plug: NGK
Air Gap: 0.75 mm (0.03 inch)
Removing the Spark Plug
1. Park the machine on a level surface, disengage
the blade-control switch, and move the
motion-control levers outward to the P
position.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Clean the area around the base of the plug to
keep dirt and debris out of the engine.

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.
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 0.75 mm (0.03 inch).
