Servicing the Spark Plugs
Check the spark plugs after every 200 operating hours.
Ensure that the air gap between the center and side
electrodes is correct before installing each spark plug. Use
a spark plug wrench for removing and installing the spark
plugs and a gapping tool/feeler gauge to check and adjust
the air gap. Install new spark plugs if necessary.
