SPARK PLUG MAINTENANCE

WARNING
DO NOT check for spark with spark
plug removed. Use only Briggs & Strat-
ton Spark Tester, to check for spark. DO
NOT crank engine with spark plug
removed.
• The electrodes on a spark plug must be clean and
sharp to produce the powerful spark required for
ignition. If the spark plug is worn or dirty the harder
it is to start your engine. Replace the spark plug
each season.
• Spark plug gap should be .64 mm or 0.025 in.
KEEP ENGINE CLEAN
Periodically remove grass and chaff build-up from
engine. Clean finger guard.
Do not spray engine with water to clean because water
could contaminate fuel. Clean with a brush or
compressed air.
WARNING
Engine should be kept clean to
reduce risk of overheating and
ignition of accumulated debris.
Clean engine when engine is cold.
