FUEL RECOMMENDATIONS
Fuel must meet these requirements:
Clean, fresh, unleaded gasoline.
A minimum of 87 octane/87 AKI (91 RON). High altitude
use, see below.
Gasoline with up to 10% ethanol (gasohol) is acceptable.
CAUTION: 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 damage the engine components and void the engine 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 certied to operate on gasoline.
The emissions control system for this engine is EM (Engine
Modications).
Figure 6
HIGH ALTITUDE
At altitudes over 5,000 feet (1524 meters), a minimum 85 oc­tane/85 AKI (89 RON) gasoline is acceptable. To remain emis­sions compliant, high altitude adjustment is required. Operation without this adjustment will cause decreased performance, in­creased fuel consumption, and increased emissions. See an authorized Briggs & Stratton Dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762 me­ters) with high altitude adjustment is not recommended.

Operation
CLEAR A CLOGGED DISCHARGE CHUTE
WARNING: Hand contact with the rotating
impeller inside the discharge
chute is the most common cause of injury
associated with snowthrowers. Never clear or unclog discharge chute with your hands, or while
engine is running. Fingers can quickly become
caught and traumatic amputation or severe laceration can result.
• SHUT OFF THE ENGINE!
• Wait 10 seconds to be sure that the impeller blades
have stopped rotating.
• Always use a clean-out tool, not your hands.
A clean-out tool (A, Figure 10) is attached to either the handle or the top of the auger housing. Use the clean-out tool to remove snow from the auger housing.
A
OPERATING TIPS
1. Most ecient snowthrowing is accomplished when snow
is removed immediately after it falls.
2. For complete snow removal, slightly overlap each swath pre­viously taken.
3. Snow should be discharged downwind whenever pos­sible.
4. For normal usage, set the skids 1/8 inch (3 mm) below the scraper bar. For extremely hard-packed snow surfaces, the skids may be adjusted upward to ensure cleaning ef-
ciency.
5. On gravel or crushed rock surfaces, the skids should be set at 1-1/4 inch (32 mm) below the scraper bar (see “Ad­just Skid Height” in the Maintenance section of this man­ual). Rocks and gravel must not be picked up and thrown by the machine.
6. After the snowthrowing job has been completed, allow the engine to idle for a few minutes, to melt snow and ice ac­cumulated on the engine.
7. Clean the snowthrower thoroughly after each use.
8. Remove ice and snow accumulation and all debris from
the entire snowthrower, and ush with water (if possible)
to remove all salt or other chemicals. Wipe snowthrower dry.
9. Before starting snowthrower, always inspect augers and impeller for ice accumulation and/or debris, which could result in snowthrower damage.
10. Check oil level before every start. Make sure the oil is at
the FULL mark on the oil ll cap/dipstick.

Drain Oil – Position snowthrower so that the oil drain plug (A, Figure 12) is lowest point on engine. When the engine is warm,
remove oil drain plug and oil ll cap and drain oil into a suitable
container.
Replace oil drain plug and tighten securely. Rell crankcase
with the recommended motor oil.
ENGINE MAINTENANCE
Check Crankcase Oil Level - Before starting engine and after
each 8 hours of continuous use. Add the recommended motor oil as required.
NOTE: Over lling the engine can aect performance. Tighten the oil ll cap securely to prevent leakage.
Change Oil - Every 50 hours of operation or at least once a
year, even if the snowthrower is not used for fty hours. Use a clean, high quality detergent oil. Fill the crankcase to FULL
line on dipstick (A, Figure 11). Be sure original container is
marked: A.P.I. service “SF” or higher. Do not use SAE10W40
oil (as it may not provide proper lubrication). See Chart for oil recommendations.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting. ** Above 80°F (27°C) the use of 10W-30 may cause increased oil con- sumption. Check oil level more frequently.

Maintenance
This snowthrower is equipped with two height adjust skids, secured to the outside of the auger housing. These elevate the front of the snowthrower.
When removing snow from a hard surface area such as a paved driveway or walk, adjust the skids up to bring the front of the snowthrower down.
When removing snow from rock or uneven construction, raise the front of the snowthrower by moving the skids down. This will help to prevent rocks and other debris from being picked up and thrown by the augers.
1. Determine how much clearance you want between the scraper bar at the bottom of the auger housing and the ground. If clearing a gravel surface, enough ground clearance is needed to prevent the unit from picking up rocks.
2. Place a block equal to the desired ground clearance under the
scraper bar.
3. Loosen the skid shoe mounting nuts (A, Figure 13) 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.
Figure 12
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 snowthrowers.
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 sucient force to cause personal injury, property damage, or
damage to the snowthrower.
Be sure to set the skid shoes at the proper height to maintain ground clearance for the type of surface being cleared.

WARNING: To ensure safety and performance levels, only original replacement shear bolts should be used.
1. Stop the engine, disengage all controls, disconnect the spark plug lead wire, and make sure all moving parts have stopped.
2. Align the hole in the auger with the hole in the auger shaft. In-
stall new shear bolt (A, Figure 15), spacer (B) and locknut (C) found in the parts bag or toolbox located on the belt cover.
NOTE: The spacer ts into the larger hole in the auger tube.
CHECK THE TIRES
Check tires for damage. Check the air pressure in the tires with an accurate gauge (see Figure 16).
CAUTION: Avoid Injury! Explosive separation of tire and rim parts is possible when they are ser-
viced incorrectly.
• Do not attempt to mount a tire without the proper equipment and experience to perform the job.
• Do not inate the tires above the maximum
pressure.
• Do not weld or heat a wheel and tire assembly.

Power Rating
The gross power rating for individual gasoline engine models is labeled in accordance with SAE (Society of Automotive Engi-
neers) code J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque values are derived at 2600 RPM for those engines with “rpm” called out on the label and 3060 RPM for all others; horsepower values are derived at 3600 RPM. The gross power curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken
with exhaust and air cleaner installed whereas gross power values are collected without these attachments. Actual gross engine
power will be higher than net engine power and is aected by, among other things, ambient operating conditions and engine-to-
engine variability. Given the wide array of products on which engines are placed, the gasoline engine may not develop the rated
gross power when used in a given piece of power equipment. This dierence is due to a variety of factors including, but not limited
to, the variety of engine components (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capac­ity limitations, Briggs & Stratton may substitute an engine of higher rated power for this engine.
