Maintenance Schedule - Briggs & Stratton 400000 Manual Del Operario

WARNING
Rapid retraction of the starter cord (kickback) will pull your hand and arm toward the
engine faster than you can let go. Broken bones, fractures, bruises or sprains could
result. When starting engine, pull the starter cord slowly until resistance is felt and then
pull rapidly to avoid kickback.
8. Electric Start, if equipped: 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.
9. 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 BRIGGSandSTRATTON.com or call 1-800-233-3723 (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 to stop the engine.
1. Disengage equipment controls. See the equipment manual for location and operation
of remote controls.
2. Move the throttle control (B, Figure 5), if equipped, to the SLOW position.
3. Turn the key switch (D, Figure 5) to the OFF or STOP position. Remove the key and
keep in a safe place out of the reach of children.
4. 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:
8
• 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.
