Maintenance - Briggs & Stratton Vanguard 580000 Operator's Manual

2. To remove the reservoir cap after engine is cool, place a thick cloth over the reservoir
cap. Slowly turn the reservoir cap counterclockwise to remove.
3. If the reservoir is dry, then add coolant to both the reservoir and to the radiator. See
the equipment manual for location, operation, and maintenance of the coolant
reservoir and the radiator.
4. To remove the radiator cap after engine is cool, place a thick cloth over the radiator
cap. Slowly turn the radiator cap counterclockwise to the first stop. If pressurized
steam escapes from the cap, stand back to avoid injury. After all pressure is
released, push down and turn the radiator cap counterclockwise to remove.
Gauges And Lights
The gauges and lights shown are typical and represent various options that can be used.
See the equipment manual for location and operation of gauges and lights.
Coolant Temperature Gauge
Indicates coolant temperature when the electric start switch is in
the ON position.
Normal range 80º -- 90º C (175º -- 195º F)
Dangerous range above 105º C (220º F)
Hour Meter Gauge
Indicates the total number of operating hours.
Fuel Gauge
Indicates the fuel remaining in the fuel tank. To minimize condensation,
keep the fuel tank full.
Temperature Light
If the temperature light comes on, the engine is overheating. Stop the
engine and check the coolant level (see the How To Check Coolant
section). Check the radiator for debris that could restrict air flow.
Ignition Light
When the electric start switch is turned to the ON position, the
ignition light should be on. When the engine is running, the
ignition light should go out. If the ignition light is out when then electric start
switch in the ON position, check for a blown fuse.
Engine Oil Pressure Light
When the electric start switch is turned to the ON position, the engine oil
pressure light should be on. When the engine is running, the engine oil
pressure light should go out. If the engine oil pressure light comes on when the
engine is running, immediately stop the engine. First, check the oil level (see the
How To Check/Add Oil section). Next, check the electrical system.
Charge Light
When the electric start switch is turned to the ON position, the charge
light should be on. When the engine is running, the charge light should go
out. If the charge light comes on when the engine is running, check the electrical
system.

WARNING
Fuel and its 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.
•
To prolong starter life, use short starting cycles, not to exceed 15 seconds per
•
minute. Extended cranking can damage the starter motor.

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: Some engines and equipment have remote controls. See the equipment manual
for location and operation of remote controls.
1. Check the oil level. See the How To Check/Add Oil section.
2. Make sure equipment drive controls, if equipped, are disengaged.
3. Turn the fuel shut-off valve (A), if equipped, to the on position (Figure 4).
4. Move the throttle control (B) slightly past the slow
5. Turn the electric start switch (C) to the on/start position (Figure 4).
NOTICE: To prolong starter life, use short starting cycles, not to exceed 15 seconds
per minute. Extended cranking can damage the starter motor.
How To Stop The Engine - Figure 4
1. Move the throttle control (B) to the slow
the off position (Figure 4). Remove the key and keep in a safe place out of the reach
of children.
2. After the engine stops, turn the fuel shut-off valve (A), if equipped, to the closed
position.

Maintenance

We recommend that you see any Briggs & Stratton 3/LC Authorized 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.
Emissions Control
Maintenance, replacement, or repair of the emissions control devices and systems
may be performed by any non-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 Warranty.
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.
