SPARK PLUG
Use only Briggs & Stratton Spark Tester (part number
19368) to check for spark.
Note: In some areas, local
law requires using resistor
spark plug to suppress
ignition signals. If this en-
gine was originally
equipped with resistor
spark plug, use same type
for replacement.
CLEANING DEBRIS
CAUTION: Do not use water to clean engine parts.
Water could contaminate fuel system. Use a brush
or dry cloth.
Daily or before every use, clean
grass, chaff or accumulated de-
bris from engine. Keep linkage,
spring and controls clean. Keep
area around and behind muffler
free of any combustible debris.
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
later shatter during operation.
• Do not tamper with governor spring, links or other parts to increase engine speed.
Replacement parts for the
muffler must be the same and
installed in the same position
as the original parts, other-
wise fire can occur.
