MAINTENANCE

ENGINE AND ENGINE PARTS

We recommend that you see an authorized Briggs & Stratton Service Dealer for all maintenance and service of the engine and engine parts. Use only genuine Briggs & Stratton parts.

WARNING	If you perform any maintenance on the engine, first disconnect the spark plug wire
	from the spark plug, and disconnect the battery at the negative terminal (electric
	starter engines only) to prevent unintentional sparking. Unintentional sparking can
	result in fire or electric shock. Unintentional start-up can result in entanglement,
	traumatic amputation or laceration. Use only correct tools.
	•	Do not strike the flywheel with a hammer or hard object because the flywheel may
WARNING
	•	later shatter during operation.
		Do not tamper with governor spring, links or other parts to increase engine speed.
MUFFLER		COMBUSTION DEPOSITS

WARNING	Replacement parts for the
	muffler must be the same and
	installed in the same position
	as the original parts, other-
	wise fire can occur.

If muffler is equipped with spark arrestor screen, re- move screen for inspection. Replace screen if damaged or

plugged.

SPARK PLUG

We recommend that after every 100-300 hours you have an authorized Briggs & Stratton Service Dealer remove combustion deposits from the cylinder, cylinder head, top of piston, and around valves.

FUEL SYSTEM

WARNING	Replacement	parts for fuel
	system (cap,	hoses, tanks,
	filters, etc.) must be the same
	as original parts, otherwise
	fire can occur.

Use only Briggs & Stratton Spark Tester (part number 19368) to check for spark.
