Maintenance Schedule - Briggs & Stratton Vanguard 540000 Manual Del Operario

• 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.
Note: Equipment may have remote controls. See the equipment manual for location and
operation of remote controls.
For information on how to start the engine, read the operating instructions supplied by
the equipment manufacturer.
Stop Engine
For information on how stop the engine, read the operating instructions supplied by the
equipment manufacturer.
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.

Service Spark Plug
See Figure: 4
Check the gap (A, Figure 4) with a wire gauge (B). If necessary, reset the gap. Install
and tighten the spark plug to the recommended torque. For gap setting or torque, see
the Specifications section.
Note: In some areas, local law requires using a resistor spark plug to suppress ignition
signals. If this engine was originally equipped with a resistor spark plug, use the same
type for replacement.
Service Exhaust System
WARNING
Running engines produce heat. Engine parts, especially muffler, become
extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc. can catch fire.
• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated debris from muffler area and cylinder area.
• It is a violation of California Public Resource Code, Section 4442, to use or
operate the engine on any forest-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark arrester, as defined in Section
4442, maintained in effective working order. Other states or federal jurisdictions
may have similar laws. Contact the original equipment manufacturer, retailer, or
dealer to obtain a spark arrester designed for the exhaust system installed on this
engine.
Remove accumulated debris from muffler and cylinder area. Inspect the muffler for
cracks, corrosion, or other damage. Remove the deflector or the spark arrester, if
equipped, and inspect for damage or carbon blockage. If damage is found, install
replacement parts before operating.
WARNING
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.
Change Engine Oil
See Figure: 5, 6, 7
Used oil is a hazardous waste product and must be disposed of properly. Do not discard
with household waste. Check with your local authorities, service center, or dealer for
safe disposal/recycling facilities.
Remove Oil
1. With engine off but still warm, disconnect the spark plug wire(s) (D, Figure 5) and
keep it away from the spark plug(s) (E).
