When Adding Fuel

For information on refueling natural or LP gas engines, read the operating instructions
supplied by the equipment manufacturer.
Start and Stop Engine
Start Engine
WARNING
Gaseous vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Starting Engine
• Ensure that spark plug, muffler, and air cleaner (if equipped) are in place and secured.
• Do not crank engine with spark plug removed.
WARNING
POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a
poisonous gas that could kill you in minutes. You CANNOT see it, smell it, or taste
it. Even if you do not smell exhaust fumes, you could still be exposed to carbon
monoxide gas. If you start to feel sick, dizzy, or weak while using this product,
shut it off and get to fresh air RIGHT AWAY. See a doctor. You may have carbon
monoxide poisoning.
• Operate this product ONLY outside far away from windows, doors and vents to reduce
the risk of carbon monoxide gas from accumulating and potentially being drawn
towards occupied spaces.
• Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms
with battery back-up according to the manufacturer's instructions. Smoke alarms
cannot detect carbon monoxide gas.
• DO NOT run this product inside homes, garages, basements, crawlspaces, sheds,
or other partially-enclosed spaces even if using fans or opening doors and windows
for ventilation. Carbon monoxide can quickly build up in these spaces and can linger
for hours, even after this product has shut off.
• ALWAYS place this product downwind and point the engine exhaust away from
occupied spaces.
NOTICE This engine was shipped from Briggs & Stratton without oil. Before you start
the engine, make sure you add oil according to the instructions in this manual. If you
start the engine without oil, it will be damaged beyond repair and will not be covered
under warranty.
1. Check the engine oil. See the Check Oil Level section.
2. See the equipment manual for starting procedure.
Stop Engine
See the equipment manual for stopping procedure.
Maintenance
NOTICE
If the engine is tipped during maintenance, the fuel tank, if mounted on
engine, must be empty and the spark plug side must be up. If the fuel tank is not empty
and if the engine is tipped in 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, if mounted
on the engine, must be empty or fuel can leak out and result in a fire or explosion.
We recommend that you see any Briggs & Stratton Authorized Service 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.

WARNING
Unintentional sparking can result in fire or electric shock.
Unintentional start-up can result in entanglement, traumatic amputation, or
laceration.
Fire hazard
Before performing adjustments or repairs:
• Disconnect the spark plug wire and keep it away from the spark 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 increase engine speed.
• Replacement parts must be of the same design and installed in the same position
as the original parts. Other parts may not perform as well, may damage the unit, and
may result in injury.
• Do not strike the flywheel with a hammer or hard object because the flywheel may
later shatter during operation.
When testing for spark:
• Use approved spark plug tester.
• Do not check for spark with spark plug removed.
Emissions Control Service
Maintenance, replacement, or repair of the emissions control devices and systems
may be performed by any off-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 Control Statements.
