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.
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 arrestor screen, remove
screen for inspection. Replace
screen if damaged or plugged.
WARNING
MUFFLER
Note: In some areas,
local law requires using

nals. If this engine was
originally equipped
with resistor spark
plug, use same type for
replacement.
