ENGINE CARE
If major engine service or repair is required, contact
an authorized engine service center. The manufac-
turer of these engines has established an excellent
world-wide engine service organization. Engine ser-
vice is very likely available from a nearby authorized
dealer or distributor. Check the yellow pages of your
local telephone directory under “Engines-Gasoline”
for the closest engine repair center or ask the dealer
from whom you purchased the power plant.
1.
Change the oil
after the first 5 hours of operation
and yearly or 100 hours thereafter under normal op-
erating conditions. Change engine oil every 50 hours
of operation if the engine is operated under heavy
load, or in high ambient temperatures.
a. Start the engine and warm it up, stop the engine
and remove the spark plug wire to prevent it
from accidently being started.
b. Remove oil drain plug at base of the engine
(Ref “B”) and drain the oil into an approved
container.
c. Remove the oil filter (Ref “C”) and dispose of it
properly.
d. Before you install the new oil filter, lightly lubri-
cate the oil filter gasket with fresh clean oil.
e. Install the oil filter by hand until the gasket
contacts the oil filter adapter, then tighten the oil
filter 1/2 to 3/4 turns.
f. Replace oil drain plug.
g. Remove oil filler plug and refill with new oil.
Refer to the table on page 5 for the proper
grade of oil based on your operating
temperature.
NOTE: This engine requires 78 to 80 ounces of oil
if it is completely drained. Use caution when refilling
the engine as some residual oil may have remained
in the engine. Always use the dipstick when filling
the engine with oil to prevent overfilling.
h. Replace filler plug.
I. Start the engine and warm it up.
J. After warming up the engine, recheck the oil
level and refill as necessary to bring it to the
proper level. See page 5 for proper oil level.
.
Checking the Oil Level
: The oil level must al-
ways be checked before the engine is started. Take
care to remove any dirt or debris from around the
oil fill plug before removing. Be sure the oil level is
maintained. Fill to the “
FULL
” mark on the dipstick.
3.
Dual Element Air Filter
: Clean and/or replace
foam pre-cleaner and air filter annually or every 100
hours. Service more often under dusty conditions.
WARNING: EQUIPMENT DAMAGE

WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Starting Engine
x
Ensure that spark plug, muffler, fuel cap and air cleaner (if equipped) are in
place and secured.
x
Do not crank engine with spark plug removed.
x
If engine floods, set choke (if equipped) to OPEN/RUN position, move throttle
(if equipped) to FAST position and crank until engine starts.
Engines give off carbon monoxide, an odorless, colorless, poison gas.
Breathing carbon monoxide can cause nausea, fainting or death.
WARNING
x
Start and run engine outdoors.
x
Do not start or run engine in enclosed area, even if doors or windows are open.
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. Push the stop switch (

If the engine does not start after repeated attempts, go to
VanguardEngines.com
or call

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.
9.
Electric Start:
Turn the electric start switch (
D

Maintenance
We recommend that you see any Briggs & Stratton 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.
WARNING:
When performing maintenance that requires the unit to be
tipped, the fuel tank must be empty or fuel can leak out and result in a fire or
explosion.
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.
Unintentional sparking can result in fire or electric shock.
Unintentional start-up can result in entanglement, traumatic
amputation, or laceration.
Fire hazard
WARNING
Before performing adjustments or repairs:
x
Disconnect the spark plug wire and keep it away from the spark plug.
x
Disconnect battery at negative terminal (only engines with electric start.)
x
Use only correct tools.
x
Do not tamper with governor spring, links or other parts to increase engine
speed.
x
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.
x
Do not strike the flywheel with a hammer or hard object because the flywheel
may later shatter during operation.
When testing for spark:
x
Use approved spark plug tester.
x
Do not check for spark with spark plug removed.
