Oil Recommendations
(see fig. © )
Engine shipped from Briggs & Stratton without oil.
Before starting engine, fill with oil. Do not over-fill.
Use a high quality detergent oil classified “For Service
SF, SG, SH, SJ” or higher such as Briggs & Stratton
30W, Part Number 100005 (20 oz.) or 100028 (48 oz.).
Use no special additives with recommended oils. Do
not mix oil with gasoline.
Choose the SAE viscosity grade of oil from this chart
that matches the starting temperature anticipated
before the next oil change. (see fig.
© )
Note: Synthetic oil meeting ILSAC
GF-2, API certification mark and API ser-
vice symbol (shown at left) with “SJ/CF
ENERGY CONSERVING” or higher, is an
acceptable oil at all temperatures. Use of
synthetic oil does not alter required oil
change intervals .
* 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-vis-
cosity oil, check oil level more frequently.
** SAE 30 oil, if used below 40° F (4° C), will result
in hard starting and possible engine bore
damage due to inadequate lubrication.
Check oil level (see fig. © )
Oil capacity is about 1.4 liters (48 ounces) if engine is
not equipped with oil filter. Oil capacity is about 1.7 liters
(56 ounces) if engine is equipped with oil filter.
Note: Oil capacity will be greater if engine is equipped
with remote oil filter.
Place engine level and clean around oil fill
➊ .
Remove dipstick ➋ , wipe with clean cloth, insert and
tighten down again. Remove dipstick and check oil level.
Oil should be at FULL mark ➌ . If oil is required, add
slowly. Tighten dipstick firmly before starting engine.
After filling with or changing oil, start and run engine at
idle for 30 seconds. Shut engine off. Wait 30 seconds
and check oil level. Check for oil leaks. Add oil, if
required, to bring level to FULL mark on dipstick.
Fuel Recommendations
Use clean, fresh, lead-free gasoline with a minimum of
77 octane. Leaded gasoline may be used if it is
commercially available and if unleaded is unavailable.
Purchase fuel in quantity that can be used within 30
days. 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
amounts of these blends can damage the fuel system
or cause performance problems. If any undesirable
operating symptoms occur, use gasoline with a lower
percentage of alcohol or ether.
This engine is certified to operate on gasoline. Exhaust
Emission Control System: EM (Engine Modifications).
Do not use gasoline which contains Methanol. Do not
mix oil with gasoline.
For engine protection, we recommend using Briggs &
Stratton Fuel Stabilizer available from an Authorized
Briggs & Stratton Service Dealer.
Check fuel level.
Before refueling, allow
engine to cool 2 minutes.
Clean around fuel fill before removing cap to refuel.
Remove cap. Fill tank to approximately 1-1/2 inches
below top of neck to allow for fuel expansion. Be careful
not to overfill.
Starting
(see figs. ¢£ )
ALWAYS KEEP HANDS AND FEET
CLEAR OF EQUIPMENT MOVING PARTS.
Do not use a pressurized starting
fluid. Vapors are flammable.
Start, store and fuel lawn mower in level position. Start
lawn mower on hard surface or over previously cut grass.
Check oil level.
Open fuel shut-off valve, if equipped.
Before starting engine (see fig. ¢ )
If engine runs low on oil, an oil pressure switch (if engine
is equipped) will either activate a warning device or stop
the engine. (Read the operating instructions supplied by
the equipment manufacturer to determine which way your
engine is equipped.) See Oil pressure on next page.
1. Open fuel shut-off valve, if equipped.
2. Move choke control ➊ to CHOKE position.
Note: If engine does not start, remove air cleaner to check
if choke valve is fully closed. If not, see Adjustments.
3. Move throttle control ➋ to FAST position.
Rewind starter, if equipped (see fig. £ )
Grasp rope handle and pull slowly until
resistance is felt. Then pull cord rapid-
ly to overcome compression, prevent
kickback and start engine. Repeat if necessary with
choke in RUN position throttle in FAST. When engine
starts, operate in FAST.
Rope starter, if equipped (see fig. £ )
Wind starter rope around pulley in
direction shown by arrow. Pull rope
handle slowly until resistance is felt.
Then pull with a quick full arm stroke to prevent
kickback. Repeat if necessary with choke in RUN and
throttle in FAST. When engine starts, operate in FAST.
When using rope starter to crank engine, use
caution so knotted end of rope does not
strike persons standing nearby.
Electric starter (see fig. £ )
On engines equipped with 12 volt starting systems, turn
key ➊ to START position or press button ➋ . Repeat if
necessary with choke off and throttle control in FAST
position. Operate engine with choke off and throttle in
FAST position.
Note: If equipment manufacturer has supplied battery,
charge it before trying to start engine, as equipment
manufacturer recommends. Use short starting cycles
(15 secs. per min.) to prolong starter life. Extended
cranking can damage starter motor.
Stopping
(see fig. ¤ )
Do not move choke control to CHOKE to stop engine.
Backfire or engine damage may occur. Move throttle
control to IDLE or SLOW position, then to STOP ➊ , or
turn key to OFF ➋ .
Always remove key from switch when equipment is not
in use or left unattended.
When engine or equipment is trans-
ported, close fuel shut-off valve, if
equipped, to prevent fuel leakage.
Adjustments
(see fig. ¥ )
To prevent acci-
dental starting, re-
move spark plug
wire ➊ and
ground it before
adjusting, and dis-
connect battery at negative terminal, if equipped.
Choke control adjustments
Remove air cleaner. Move choke control to CHOKE
position. Carburetor choke valve ➋ should be fully
closed. If not, loosen casing clamp screw ➌ . Then
move casing, wire and engine choke lever ➍ in
direction of arrow until choke is completely closed.
Tighten casing clamp screw. Replace air cleaner.
Throttle control adjustments
Remove air cleaner. Move throttle control to FAST
position. Swivel ➎ should be against side of quarter
circle ➏ . If not, loosen casing clamp screw ➐ . Move
casing and wire ➑ in direction shown until swivel is
against side of quarter circle. Tighten casing clamp
screw. Replace air cleaner.
Check operation of controls. Readjust if necessary.
Carburetor adjustments
The manufacturer of the equipment on which
this engine is installed specifies top speed at
which the engine will be operated. DO NOT
EXCEED this speed.
See an Authorized Briggs & Stratton Dealer for
carburetor adjustment.
Only idle speed is adjustable. Air/fuel mixture is not
adjustable. In the U.S.A. start engine and warm up
approximately 5 minutes before adjusting. With engine
running, place throttle control in SLOW position. Rotate
carburetor throttle lever against Idle speed screw and
hold. Adjust idle speed screw to obtain 1400 rpm.
(Governed idle has been set to 1750 rpm at the factory.)
