sumption. Check oil level more frequently.
Fuel Recommendations
Fuel must meet these requirements:
Clean, fresh, unleaded gasoline.
A minimum of 87 octane / 87 AKI (91 RON). For high
altitude use, see below.
Gasoline with up to 10% ethanol (gasohol) is acceptable.
NOTICE: Do not use unapproved gasolines, such as E15 and
E85. Do not mix oil in gasoline or modify the engine to run on
alternate fuels. Use of unapproved fuels will cause damage
to engine components, which will not be covered under
warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See Storage. All fuel is not the
same. If starting or performance problems occur, change
fuel providers or change brands. This engine is certified to
operate on gasoline. The emissions control system for this
engine is EM (Engine Modifications).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane / 85 AKI (89 RON) gasoline is acceptable. For
carbureted engines, high altitude adjustment is required
to remain emissions compliant. Operation without this
adjustment will cause decreased performance, increased
fuel consumption, and increased emissions. Contact a
Briggs & Stratton Authorized Service Dealer for high altitude
adjustment information.
Operation of the engine at altitudes below 2,500 feet
(762 meters) with the high altitude adjustment is not
recommended. For Electronic Fuel Injection (EFI) engines, no
high altitude adjustment is necessary.

Clearing a Clogged Discharge Chute
DANGER
Amputation hazard
The discharge chute contains a rotating impeller to
throw snow. Fingers can quickly become caught in
the impeller. Never clear or unclog the discharge
chute with your hands. Always use a clean-out tool.
Failure to observe these safety instructions will result
in traumatic amputation or severe laceration.
Hand contact with the rotating impeller inside the dis-
charge chute is the most common cause of injury associ-
ated with snowthrowers. Never use your hands to clean out
the discharge chute.

10. Depress the starter push button (B). After you start the
engine, first disconnect the extension cord from the wall
receptacle and then from the power cord receptacle (A).
NOTICE: To extend the life of the starter, use short starting
cycles (ve seconds maximum). Wait one minute between
starting cycles.
NOTE: If engine oods, set the choke to the OPEN/RUN position
and crank until the engine starts. If the engine does not start after
three attempts, see an authorized dealer.
11. Allow the engine to warm up for several minutes. Then
slowly move the choke control knob to the RUN position.

Skid Shoe Height Adjustment
DANGER
Amputation hazard
The discharge chute contains a rotating impeller to throw
snow. Fingers can quickly become caught and traumatic
amputation or severe laceration will result. Hand contact
with the rotating impeller inside the discharge chute is the
most common cause of injury associated with snowthrow-
ers.
Turn the engine OFF, wait for all moving parts to stop, and
remove the engine key before performing any maintenance
or repairs.
WARNING
Thrown objects hazard
Objects such as gravel, rocks, or other debris, if struck
by the impeller, may be thrown with sufficient force to
cause personal injury, property damage, or damage to the
snowthrower.
Be sure to set the skid shoes at the proper height to main-
tain ground clearance for the type of surface being cleared.
This snowthrower is equipped with two skid shoes secured to
the outside of the auger housing. These adjust the height of
of the front of the snowthrower.
When removing snow from a hard surface area such as a
paved driveway or walk, raise the skid shoes to bring the
front of the snowthrower down.
When removing snow from gravel-covered or uneven surfac-
es, lower the skid shoes to bring the front of the snowthrower
up. This will help to prevent rocks and other debris from being
picked up and thrown by the augers.
1. Determine the clearance needed between the scraper
bar at the bottom of the auger housing and the ground.
2. Place a block with a thickness equal to the desired
ground clearance under the scraper bar.
3. Loosen the skid shoe mounting nuts (A, Figure 9) and
push the skid shoe (B) down until it touches the ground.
Re-tighten mounting nuts.
4. Set the skid shoe on the other side at the same height.

WARNING
Fire and explosion hazard
Fuel is highly flammable and its vapors are explosive.
Fumes may travel to a distant ignition source and an explo-
sion and/or fire may result.
Handle gasoline carefully. Never store the unit, with fuel in
the tank, indoors or in a poorly ventilated enclosure where
fuel fumes could reach an open flame, spark, pilot light,
such as a furnace, water heater, or clothes dryer.
Storage
Equipment
Thoroughly clean the unit.
Lubricate the hex shaft (see Maintenance section).
Make sure all nuts, bolts, and screws are securely fas-
tened. Inspect all visible moving parts for damage, break-
age, and wear. Replace if necessary.
Apply a rust preventative to any bare metal parts of the
snowthrower auger and impeller.
If possible, store the unit indoors and cover it to give pro-
tection from dust and dirt.
If the machine must be stored outdoors, cover it with a
heavy tarpaulin.
Fuel System
Fuel can become stale when stored over 30 days. Stale fuel
causes acid and gum deposits to form in the fuel system or
on essential carburetor parts. To keep fuel fresh, use Briggs
& Stratton® Advanced Formula Fuel Treatment & Stabi-
lizer, available wherever Briggs & Stratton genuine service
parts are sold.
There is no need to drain gasoline from the engine if a fuel
stabilizer is added according to instructions. Run the en-
gine for 2 minutes to circulate the stabilizer throughout the
fuel system before storage. If gasoline in the engine has not
been treated with a fuel stabilizer, it must be drained into an
approved container. Run the engine until it stops from lack
of fuel. The use of a fuel stabilizer in the storage container is
recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil. See En-
gine Maintenance section.
Before starting the unit after it has been stored:
• Check all uid levels. Check all maintenance items.
• Perform all recommended checks and procedures found
in this manual.
• Allow the engine to warm up for several minutes before
use.
