Stop The Engine; Maintenance Information; Maintenance Schedule - Briggs & Stratton 090000 Operator's Manual

• Do not put an object into the battery contacts. This will short-circuit the battery.
• All persons or children with decreased abilities (physical, sensory, mental) must
not use the charger unless looked after by an adult.
Extension cord
• Use of an incorrect extension cord could result in an electric shock or fire. If you
use an extension cord, make sure that:
1. The pins on the plug of the extension cord are the same number, size, and shape
as those of the plug on the charger;
2. The extension cord is correctly connected and in good electrical condition; and
3. For the correct AC ampere rating of the charger, make sure that the wire size is a
minimum of 16 AWG.
When you keep the battery pack in storage
• Keep the battery charger dry. Do not let the battery pack get wet.
Before you make adjustments or repairs
• Models with portable battery pack: Remove the battery pack from the battery
tray.
• Models with integrated battery pack: Disconnect the wire harness from the
starter motor.
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.
NOTE: Your equipment could have remote controls. Refer to the equipment manual for
location and operation of remote controls
1. Check the Engine Oil. See Check Oil Level section.
2. Models with Portable Battery Pack: Put the battery pack (B, Figure 10) in the
engine battery tray on top of the engine. Make sure that the battery pack is safely
installed. The battery pack can represent equipment key in some instances.
NOTE: Models with Portable Battery Pack: To wake-up a new battery, a First Time
quick charge of approximately ten (10) seconds is required. See When to Charge the
Battery Pack section.
3. Make sure that the equipment drive controls, if equipped, are disengaged.
4. Move the fuel shut-off valve (D, Figure 11), if equipped, to the OPEN position.
5. Move the throttle control (A, Figure 11), if equipped, to the FAST position. Operate
the engine in the FAST position.
6. Models with Electric Start Switch: Hold the engine stop lever (C, Figure 12), if
equipped, against the handle. Move the electric start switch to the START position.
See the equipment manual for the location and operation of the electric start switch.
7. Models without Electric Start Switch: Hold the engine stop lever (C, Figure 12)
against the handle. The engine will automatically start. See the equipment manual
for operation of the engine stop lever.
NOTICE To extend the life of the starter, use short starting cycles (five seconds
maximum). Wait one minute between starting cycles.
Models with Portable Battery Pack: If the engine will not crank and the battery
pack display lights flash, then the battery pack temperature is too hot or the current
draw is too high. All four battery display lights (H, Figure 13) will flash a warning
for 10 seconds. The battery pack does not have a fuse, but will automatically reset
after 10 seconds. If battery pack temperature is too hot (over 140°F, 60°C), remove
the battery and let it cool. To prevent too much current draw on lawnmowers, keep
the mower housing clean of accumulated grass and debris.
NOTE: If the engine does not start after 2-3 attempts, contact your local dealer or go to
BRIGGSandSTRATTON.COM or call 1-800-444-7774 (in USA).

4. After the engine stops, move the fuel shut-off valve (D, Figure 16) to the CLOSED
position.
5. Models with Portable Battery Pack: Remove the battery pack. The battery pack
can represent equipment key in some instances.
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.
• Models with portable battery pack: Remove the battery pack from the battery
tray. On some applications, the battery pack may be the equipment key.
• Models with integrated battery pack: Disconnect the wire harness from the
starter motor.
• 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.
