• Ensure that spark plug, muffler, fuel cap and air cleaner (if equipped) are in place
and secured.
• Do not crank engine with spark plug removed.
• If engine floods, set choke (if equipped) to OPEN / RUN position, move throttle (if
equipped) to FAST position and crank until engine starts.
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.
•
Electronic Fuel Injection (EFI) System:
This features Electronic Fuel Injection. It
does not have a 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 and throttle control. This type does not have a primer.
Note:
Equipment may have remote controls. See the equipment manual for location and
operation of remote controls.
Electronic Fuel Injection (EFI) System
1.
Check the engine oil. See the
Check Oil Level
section.
2.
Make sure equipment drive controls, if equipped, are disengaged.
3.
Move the fuel shut-off (A, Figure 5), if equipped, to the OPEN position.
4.
Move the throttle control to the SLOW position.
5.
Turn the electric start switch (D, Figure 5) to the ON or START position.
NOTICE
To extend the life of the starter, use short starting cycles (five seconds
maximum). Wait one minute between starting cycles.
Note:
If the engine does not start after repeated attempts, contact you local dealer or go
to
VanguardEngines.com
or call
1-800-999-9333
(in USA).
Choke System
1.
Check the engine oil. See the
Check Oil Level
section.
2.
Make sure equipment drive controls, if equipped, are disengaged.
3.
Move the fuel shut-off (A, Figure 5), if equipped, to the OPEN position.
4.
Move the throttle control to the FAST position.
5.
Move the choke control (C, Figure 5), if equipped, to the CLOSED position.
Note:
To start the engine with a dry fuel system (first time starting or after running out of
fuel), additional cranking time in the choke position will be required. This will give the fuel
pump time to prime the fuel system.
6.
Turn the key switch (D, Figure 5) to the ON or START position.
7.
If the engine fires but will not continue to run, move the choke control (C, Figure 5)
to the OPEN position to start the engine.
NOTICE
To extend the life of the starter, use short starting cycles (five seconds
maximum). Wait one minute between starting cycles.
8.
As the engine warms up, move the choke control (C, Figure 5) to the OPEN
position.
Note:
If the engine does not start after repeated attempts, contact you local dealer or go
to
VanguardEngines.com
or call
1-800-999-9333
(in USA).
Stop Engine
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Do not choke the carburetor, if equipped, to stop the engine.
1.
With the throttle control, if equipped, in the SLOW position, turn the key switch (D,
Figure 5) to the OFF position. Remove the key and keep in a safe place out of the
reach of children.
2.
After the engine stops, move the fuel shut-off (A, Figure 5), if equipped, to the
CLOSED position.
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.
Maintenance Schedule
Every 8 Hours or Daily
• Check engine oil level
• Clean area around muffler and controls
Every 100 Hours or Annually
