against the handle (Figure 5).
5. Firmly hold the starter cord handle (E). Pull the starter cord handle slowly until

Maintenance
NOTICE: If the engine is tipped during maintenance, the fuel tank must be empty and
thesparkplugsidemust be up. If thefuel tank is not emptyand if theengine is tippedin
any other direction, it may be difficult to start due to oil or gasoline contaminating the air
filter and/or the spark plug.
WARNING: When performing maintenance that requires the unit to be
tipped, the fuel tank must be empty or fuel can leak out and result ina fire or
explosion.
We recommend that you see any Briggs & Stratton Authorized Dealer for all
maintenance and service of the engine and engine parts.
NOTICE: All the components used to build this engine must remain in place for proper
operation.

may be performed by any non-road engine repair establishment or individual.
However, to obtain “no charge” emissions control service, the work must be performed
by a factory authorized dealer. See the Emissions Warranty.
Unintentional sparking can result in fire or electric shock.
Unintentional start-up can result in entanglement, traumatic
amputation, or laceration.

Disconnect the spark plug wire and keep it away from thespark plug.
Disconnect battery at negative terminal (only engines with electric start.)
Use only correct tools.
Do not tamper with governor spring, links or other parts to increaseengine
speed.
Replacement parts must be of the same design and installed in the same
position as the original parts. Other parts may notperform as well, may damage
the unit, and may result in injury.
