Fast retraction of the starter cord (kickback) will pull your hand and arm to the engine
faster than you can let go. Broken bones, fractures, bruises or sprains could result. To
prevent kickback when you start the engine, pull the starter cord slowly until resistance
is felt and then pull quickly.
8. Electric Start, if installed: Turn the electric start switch (D, Figure 4) to the ON or
START position.
NOTICE
To extend the life of the starter, use short start cycles (five seconds maximum). Wait one
minute between start cycles.
If the engine does not start after 3 or 4 times, contact your local dealer or go to
vanguardpower.com or call 1-800-999-9333.

Maintenance
Maintenance Information
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
During maintenance if it is necessary to tilt the unit, make sure that the fuel tank, if
mounted on the engine, is empty and that the spark plug side is up. If the fuel tank is not
empty, leakage can occur and could result in a fire or an explosion. If the engine is tilted
in a different direction, it will not easily start because of oil or fuel contamination of the air
filter or the spark plug.
WARNING
Accidental engine spark can cause an electric shock, fire or explosion and could
result in entanglement, traumatic amputation or laceration.
Before you make adjustments or repairs:
• Disconnect all spark plug wires and keep them away from the spark plugs.
• Disconnect the battery wire from the negative battery terminal (only engines with
electric start).
• Use only the correct tools.
When you check for spark:
• Use an approved spark plug tester.
• Do not check for spark with the spark plug removed.
WARNING
All the components used to assemble this engine must stay in the initial position
for correct operation. Damage or injury can occur if you use incorrect parts or you
do not replace all parts on the engine.
• Replacement parts must be of the same design and installed in the same
position as initial parts.
• If installed, do not change the governor spring, links, or other parts to increase
the engine speed.
See a Briggs & Stratton Authorized Service Dealer for all maintenance and servicing of
the engine and engine parts.
Emissions Control Service
For maintenance, replacement, or repair of emissions control devices and
systems, contact a qualified off-road engine repair establishment or service

spark plug gap. Install and tighten the spark plug to the correct torque. For gap and
torque specifications, refer to the Specifications section.
Servicing the Exhaust System
WARNING
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
Combustible materials, such as leaves, grass and brush, can catch fire.
• Before you touch the engine or muffler, stop the engine and wait two (2)
minutes. Make sure that the engine and muffler are safe to touch.
• Remove debris from the muffler and engine.
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;
reference Federal Regulation 36 CFR Part 261.52. Contact the original equipment
manufacturer, retailer, or dealer to obtain a spark arrester designed for the exhaust
system installed on this engine.
Remove debris from the 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 the replacement parts
before you operate the equipment.
