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.
Determine The Starting System
Before starting the engine, you must determine the type of starting system that is on
your engine. Your engine will have one of the following types.
• ReadyStart
®
System: This features a temperature controlled automatic choke. It
does not have a primer.
• Electronic Fuel Management System: This features an Electronic Control Unit
that monitors engine and temperature conditions. It does not have a manual choke
or a primer.
• Choke System: This features a choke to be used for starting in cool
temperatures. Some models will have a separate choke control while others will
have a combination choke / throttle control. This type does not have a primer.
To start your engine, follow the instructions for your type of starting system.
Note: Equipment may have remote controls. See the equipment manual for location and
operation of remote controls.

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.
