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.
WARNING
•
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.
MUFFLER
Replacement parts for the muffler
must be the same and installed in the
same position as the original parts,
otherwise fire can occur.
If muffler is equipped with spark arrester screen, remove screen
for inspection. Replace screen if damaged or plugged.
WARNING
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 igni-
tion signals. If this engine
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 accumulated debris from
engine. Keep linkage, spring and controls clean. Keep area
around and behind muffler free of any combustible debris.
Engine parts should be kept clean to
reduce the risk of overheating and
ignition of accumulated debris.
