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.
CLEANING DEBRIS
CAUTION: Do not use water to clean engine parts.
Water could contaminate fuel system. Use a brush
or dry cloth.
Engine parts should be kept
clean to reduce the risk of
overheating and ignition of accu-
mulated debris. This is especial-
ly important if cutting tall grass.
WARNING
Daily or before every use, clean grass, chaff or accumu-
lated debris from engine. Keep linkage, spring and controls
clean. Keep area around and behind muffler free of any
combustible debris.
