Oil Recommendations(see fig. ©)
Engineshipped from Briggs & Stratton without oil.
Beforestarting engine, fill with oil. Do not over-fill.
Usea high quality detergent oil classified “For Service
SF,SG, SH, SJ” or higher such as Briggs & Stratton
30W,Part Number 100005. Use no spec ialadditives
withrecommended oils. Do not mix oil with gasoline.
Choose the SAE viscosity grade of oil from this chart
that matches the starting temperature anticipated
beforethe next oil change.
Note:Synthetic oil meeting ILSAC GF-2,
API certification mark and API service
symbol (shown at left) with “SJ/CF
ENERGYCONSERVING” or higher,is an
acceptableoil at all temperatures. Use of
syntheticoil does not alter required oil
changeintervals.
*Air cooled engines run hotter than automotive
engines. The use of non-synthetic multi-viscosity
oils (5W-30, 10W-30, etc.)in temperatures above
40°F(4°C) will result in higher than normal oil
consumption. When using a multi-viscosity oil,
checkoil level more frequently.
** SAE30 oil, if used below 40°F(4°C),willresult
in hard starting and possible engine bore
damagedue to inadequate lubrication.
Checkoil level. (Oil capacity is about 21 oz. or 0.6 liter.)
Placeengine level and clean around oil fill .
Remove dipstick, wipe with clean cloth, insert and
tighten down again. Remove dipstick and check oil
level.Oil should be at FULL mark .
OR
Remove oil filler plug . Oil should be full to
overflowing.
Ifoil is required, add slowly.Tighten dipstick or oil filler
plugfirmly before starting engine.
Fuel RecommendationsUse clean, fresh, lead-free, regular, gasoline with a
minimumof 77 octane. Leaded gasoline may be used if
itis commercially available and if unleaded is unavail-
able.Purchase fuel in quantity that can be used within
30days. See Storage.
In U.S.A. leaded gasoline may not be used. Some
fuels,called oxygenated or reformulated gasolines, are
gasolines blended with alcohols or ethers. Excessive
amountsof these blends can damage the fuel system
or cause performance problems. If any undesirable
operatings ymptoms occur,use gasoline with a lower
percentageof alcohol or ether.
Thisengine is certified to operate on gasoline. Exhaust
EmissionControl System: EM (Engine Modifications).
Donot use gasoline which contains Methanol. D onot
mixoil with gasoline.
Forengine protection, we recommend using Briggs&
Stratton Fuel Stabilizer available from an Authorized
Briggs& Stratton Service Dealer.
Checkfuel level.
Beforerefueling, allow
engineto cool 2 minutes.
Cleanaround fuel fill before removing cap to refuel. Fill
tankto approximately 1/2 inch below lowest portion of
fillopening to allow for fuel expansion. Be careful not to
overfill.
Starting (seefigs. ¡¢£)
ALWAYS KEEP HANDS AND FEET
CLEAROFEQUIPMENT MOVINGPARTS.
Do not use a pressurized starting
fluid.Vapors are flammable.
Start,store and fuel equipment in level position.
Checkoil level.
CAUTION:OIL GARD®, if equipped, (see10 fig. ¡)
isintended to prevent starting an engine that is low on oil.
OIL GARD®may not shut down a running engine.
Engine damage may occur if oil level is not properly
maintained and will void warranty coverage. Always
checkoil level before starting engine.
Ifengine is equipped with OIL GARD®, and if engine
runslow on oil, light on engine warns of low oil level. If
light flickers and engine cannot be started, or has
stoppedand cannot be restarted, add oil. Fill to point of
overflowingat oilfillcapor toFULLmarkon dipstick.Do
notover-fill.
Beforestarting (seefig. ¢)
1. Movechoke control to CHOKE or START position .
Note: If engine does not start, remove air cleaner to
check choke. Choke must fully close . If not, see
Adjustments.
2. If equipment has separate choke and throttle
controls,move throttle control to FAST position .
3. Movestop control to ON position , if equipped.
Rewindstarter (seefig. £)
Grasprope handle and pull slowly until
resistanceis felt. Then pull cord rapid-
ly to overcome compression, prevent
kickback and start engine.Repeat i
f
necessary with choke in RUN position and throttle in
FAST.When FAST. When engine starts, operate in
FASTposition.
Electricstarter (seefig. £)
Onengines equipped with 12 voltstarting systems, turn
key to START position or press starter button .
Repeat if necessary with throttle control in FAST
position.When engine starts, operate in FAST position.
Note: If equipment manufacturer has supplied battery,
charge it before trying to start engine, as equipment
manufacturerrecommends.
Note:Use short starting cycles (15 secs. per min.) to
prolong starter life. Extended cranking can damage
startermotor.
Stopping (seefig. ¤)
Donot move choke control to CHOKE to stopengine.
Backfire or engine damage may occur. Move throttle
controlto IDLE or SLOW position , if equipped. Then
turn key to OFF or move stop control STOPor OFF
position.
Adjustments (seefig. ¥)
To prevent acci-
dental starting, re-
move spark plug
wireand ground
it before adjus ting, and disconnect battery at negative
terminal,if equipped.
Throttlecontrol adjustments
Remove air cleaner (air cleaner base not shown for
clarity).Loosen casingclampscrewon carburetoror
controlplate.
Ifchoke control is remote, push bell crank either way
untilit just touches washer .
Ifchoke control is manual, move casing and wire in
directionof arrow to end of travel.
Movethrottle control to FAST position. Tighten casing
clampscrew. Replace air cleaner.
Fixedgovernor control
Governorcontrol has been set to permit top no-load
RPM specified by equipment manufacturer. If adjust-
ment is required, consult any Briggs & Stratton
AuthorizedService Dealer.
Checkstop switch
Movethrottle control to STOP position, if so equipped.
Governor control lever on carburetor or control plate
mustmake good contact w ith stop switch. Check and
readjustif necessary.
Carburetoradjustment
Themanufacturer of the equipment on which
thisengine is installed specifies top speed at
whichthe engine will be operated. DO NOT
EXCEEDthis speed.
See an Authorized Briggs & Stratton Dealer for
carburetoradjustment.
Thecarburetor on this engine is low emission. Air/fuel
mixtureis not adjustable.Only the idle speed screw is
adjustable.Governed idle has been set to 1750 at the
factory.
Toadjust the idle s peed, start engine and warm up
approximately 5 minutes. Then with engine running,
placethrottle control in SLOW position. Rotate carbu -
retorthrottle lever agains t the throttle stop and holdit
whileadjusting idle speed screw to obtain 1100 rpm.
