FUEL RECOMMENDATIONS
Use clean, fresh, lead free, regular gasoline with a minimum of
85 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
instructions.
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.
ADDING FUEL
Fig. 4
WARNING
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
Fig. 5
WARNING
1. Add oil. Ensure level is at FULL mark on dipstick. Use
the correct oil type for expected starting temperature.
DO NOT OVERFILL.
2. Fill with fresh gasoline.
Ê
3. Push stop switch to ON position.
Ë
Move CHOKE to choke position.
Locate primer bulb. Firmly press with finger
Note: If temperature is 15° F (-9° C) or higher push
primer two times, if below 15° F (-9° C) push primer
four times.
Í
4. Grasp rope handle. Pull slowly until resistance is felt,
then pull rapidly to start engine and avoid kickback.
OPERATING ENGINE
After engine has started, let it warm up several seconds to
several minutes, depending on outside temperature. Slowly
adjust CHOKE to RUN position. Wait until the engine runs
smoothly before each choke adjustment.
• Do not tip engine or equipment at angle which causes
gasoline to spill.
• Do not choke carburetor to stop engine.
Periodically remove debris buildup under housing.
(See Maintenance.)

PLUGS
Change oil after first 5 to 8 hours of use, then every 50 hours
or every season. Change oil every 25 hours when operating
the engine under heavy load or in high temperatures. Engine is
equipped with either top or bottom oil drain.
1. Run engine until it runs out of fuel. Otherwise, fuel can
leak out, creating a fire/explosion hazard, when you tip
engine in Step 4 for top oil drain.
2. Disconnect spark plug wire and keep it away from spark
plug.
