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-viscosity oil,
check oil level more frequently.
** Use of SAE 30 oil below 40° F (4° C) will result in
hard starting and possible engine damage due to
inadequate lubrication.
Check oil level (see fig. © )
Oil capacity is about 1.8 liters (60 ounces) if engine is
not equipped with oil filter. Oil capacity is about 1.9 liters
(64 ounces) if engine is equipped with oil filter.
Note: Oil capacity will be greater if engine is equipped
with remote oil filter.
➊
Place engine level and clean around oil fill .
➋
Remove dipstick , 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, regular lead-free gasoline with a
minimum of 85 octane. Leaded gasoline may be used if
it is commercially available and if unleaded is unavail-
able. 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.

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 light.
(Read the operating instructions supplied by the
equipment manufacturer.) See Oil pressure next page.
1. Open fuel shut-off valve, if equipped.
2. Move choke control to CHOKE position
Note: If engine does not start, remove air cleaner to check
choke. Choke must fully close. If not, see Adjustments.
➋
3. Move throttle control to FAST position.
£
Electric starter (see fig. )
➊
Turn key to START position or press button
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.
CAUTION:If engine is equipped with battery for electric
starter, do not operate engine with battery disconnected.
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
➋
turn key to OFF .
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.
connect battery at negative terminal, if equipped.
Choke control adjustments
Remove air cleaner. Move choke control to CHOKE
position. Carburetor choke valve should be completely
closed. If not, loosen casing clamp screw
casing and wire ➌ in direction of arrow to end of travel.
Tighten casing clamp screw. Replace air cleaner.
Throttle control adjustments
Remove air cleaner. Move throttle control to FAST
position. Swivel ➍ should be against throttle stop
not, loosen casing clamp screw
in direction shown by arrow until swivel is against
throttle stop. 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.
The carburetor on this engine is low emission. It is not

adjustable, except for idle speed. Governed idle speed
is 1750 rpm, set at the factory. In the U.S.A., if idle
speed does require adjusting, start engine and warm
up approximately 5 minutes before adjusting. With
engine running, place throttle control in SLOW position.
Rotate carburetor throttle lever against the idle speed
screw and hold it. Turn idle speed screw to obtain 1500

performance is observed, contact a Briggs & Stratton
Authorized Service Dealer for a high altitude carburetor
air bleed.
