Stop The Engine; Maintenance Information; Maintenance Schedule - Briggs & Stratton 250000 Operator's Manual

WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
When you start the engine
• Make sure that the spark plug, muffler, fuel cap and air cleaner (if equipped) are
correctly installed.
• Do not crank the engine with the spark plug removed.
• If the engine is flooded, set the choke (if equipped) to the OPEN or RUN
position. Move the throttle (if equipped) to the FAST position and crank until the
engine starts.
• If there is natural or LP gas leakage in the area, do not start the engine.
• Because vapors are flammable, do not use pressurized starter fluids.
WARNING
POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a
poisonous gas that could kill you in minutes. Although you do not smell exhaust
fumes, you could still be exposed to dangerous carbon monoxide gas. If you feel
sick, dizzy, or weak while you use this product, get to fresh air RIGHT AWAY. See
a doctor. You may have carbon monoxide poisoning.
• Carbon monoxide gas can collect in occupied spaces. To reduce the risk of
carbon monoxide gas, ONLY operate this product outdoors and far away from
windows, doors and vents.
• Install battery-operated carbon monoxide alarms or plug-in carbon monoxide
alarms with battery back-up as specified by the manufacturer's instructions.
Smoke alarms cannot sense carbon monoxide gas.
• DO NOT operate this product in homes, garages, basements, crawlspaces,
sheds, or other closed spaces, even if you use fans or open doors and windows
for ventilation. After the operation of this product, carbon monoxide can quickly
collect in these spaces and stay for hours.
• ALWAYS put this product downwind and point the engine exhaust away from
occupied spaces.
NOTICE
This engine was shipped from Briggs & Stratton without oil. Equipment manufacturers or
dealers could have added oil to the engine. Before you start the engine for the first time,
make sure that the oil is at the correct level. Add oil as specified by the instructions in
this manual. If you start the engine without oil, damage will occur and the engine will not
be repaired under warranty.
1. Check the engine oil. See the Check Oil Level section.
2. Make sure equipment drive controls, if equipped, are disengaged.
3. Push the stop switch (A, Figure 7), if equipped, to the ON position.
4. Move the throttle control (B, Figure 7), if equipped, to the FAST position. Operate
the engine in the FAST position.
5. Move the choke control (C, Figure 7) to the CHOKE position.
NOTE: The choke is usually not necessary when you start a warm engine.
6. Move the fuel shut-off (D, Figure 7), if equipped, to the OPEN position.
7. Rewind Start, if equipped: Tightly hold the starter cord handle (E, Figure 7). Pull
the starter cord handle slowly until resistance is felt, then pull quickly.
WARNING
Fast retraction of the starter cord (kickback) will pull your hand and arm to the engine
faster than you can let go. Broken bones, fractures, bruises or sprains could result. To
prevent kickback when you start the engine, pull the starter cord slowly until resistance
is felt and then pull quickly.
8. Electric Start, if equipped: Turn the electric start switch (F, Figure 7) to the ON or
START position.
NOTICE
To extend the life of the starter, use short start cycles (five seconds maximum). Wait one
minute between start cycles.
9. As the engine warms, move the choke control (C, Figure ) to the RUN position.
If the engine does not start after 3 or 4 times, contact your local dealer or go to
BRIGGSandSTRATTON.COM or call 1-800-444-7774.

Maintenance

Maintenance Information

WARNING
During maintenance if it is necessary to tilt the unit, make sure that the fuel tank, if
mounted on the engine, is empty and that the spark plug side is up. If the fuel tank is not
empty, leakage can occur and could result in a fire or an explosion. If the engine is tilted
in a different direction, it will not easily start because of oil or fuel contamination of the air
filter or the spark plug.
We recommend that you see a Briggs & Stratton Authorized Service Dealer for all
maintenance and servicing of the engine and engine parts.
NOTICE
All the components used to build this engine must remain in place for correct operation.
WARNING
Accidental engine spark can cause an electric shock or fire and could result in
entanglement, traumatic amputation or laceration.
Before you make adjustments or repairs:
• Disconnect the spark plug wire and keep it away from the spark plug.
• Disconnect the battery wire from the negative battery terminal (only engines with
electric start.)
• Use only the correct tools.
When you check for spark:
• Use an approved spark plug tester.
• Do not check for spark with the spark plug removed.
Emissions Control Service
For maintenance, replacement, or repair of emissions control devices and
systems, contact a qualified off-road engine repair establishment or service
technician. However, for "no charge" emissions control service, the work must be done
by a factory authorized dealer. Refer to the Emissions Control Statements.
