Maintenance Information; Maintenance Schedule - Briggs & Stratton 100000 Operator's Manual

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.
NOTE: Some engines and equipment have remote controls. Refer to the equipment
manual for the location and operation of remote controls.
1. Check the engine oil. See the Check Oil Level section.
2. Make sure that the equipment drive controls, if installed, are disengaged.
3. Turn the stop switch (A, Figure 7), if installed, to the ON position.
4. Move the throttle control (B, Figure 7), if installed, to the FAST position. Operate the
engine in the FAST position.
5. Move the choke control (C, Figure 7) to the CLOSED position.
NOTE: Choke is usually not necessary when you start a warm engine.
6. Move the fuel shut-off (D, Figure 7), if installed, to the OPEN position.
7. 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. As the engine warms, move the fuel shut-off (D, Figure 7), if installed, to the
CLOSED position.
NOTE: If the engine does not start after 2-3 attempts, go to
BRIGGSandSTRATTON.COM or call 1-800-444-7774 (in USA).
Stop the Engine
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
• Do not choke the carburetor (if equipped) to stop the engine.
Stop Switch, if installed: Move the stop switch (A, Figure 8) to the STOP position.
1.
2. Throttle Control, if installed: Move the throttle control (B, Figure 8) to the SLOW
position and then to the STOP position.
3. After the engine stops, move the fuel shut-off (D, Figure 8), if installed, to the
CLOSED position.
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.

by a factory authorized dealer. Refer to the Emissions Control Statements.
Adjust the Engine Speed
NOTICE
The equipment manufacturer specifies the maximum speed for the engine as installed
on the equipment. Do not exceed this speed. If you are not sure what the equipment
maximum speed is, or what the engine speed is set to from the factory, contact a Briggs
& Stratton Authorized Service Dealer for assistance. For safe and correct operation
of the equipment, the engine speed should only be adjusted by a qualified service
technician.
Adjust the Carburetor
Small carburetor adjustments could be required to compensate for differences in fuel,
temperature, altitude or load.
