Servicing the Spark Plug

Service Interval: Every 100 hours—Check the spark plug(s).
Make sure 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(s) and a
gapping tool/feeler gauge to check and adjust the air gap.
Install a new spark plug(s) if necessary.
Type: NGK BPR4ES (or equivalent)
Air Gap: 0.76 mm (0.030 inch)
Removing the Spark Plug
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.

Note: Blowing out the cavity with compressed air is
usually the most effective method for cleaning. The
spark plug is most accessible when the blower housing
is removed for cleaning.
Checking the Spark Plug
Important: Never 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 0.76 mm (0.030 inch).
