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 wires
from the spark plugs, 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, other-
wise fire can occur.
If muffler is equipped with spark
arrestor screen, remove
screen for inspection. Replace screen if damaged or plugged.
WARNING
FUEL SYSTEM
Replacement parts for fuel
system (cap, hoses, tanks,
filters, etc.) must be the same
as original parts, otherwise
fire can occur.
WARNING
FUEL FILTER (if equipped)
[1] Disconnect spark plug
wires and keep away
from spark plugs.
[2] Drain fuel tank or close
fuel shut-off valve before
replacing fuel filter.
Otherwise, fuel can leak
out, creating a fire/explo-
sion hazard.
