FILL GAS: This engine is certified to operate on
gasoline. Exhaust Emission Control System: EM (Engine Modifications).
,_ WARNING: Alcohol blended
fuels (called gasohol or
those using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel sys- tem of an engine while in storage.
NOTE: To avoid engine problems, the fuel system must be emptied before
storage for 30 days or longer. Start the engine and let it run until the fuel lines and carburetor are empty. Use fresh
fuel next season. See the Storage
1741476 11
section in this manual for additional in-
formation.
Never use engine or carburetor cleaner products in the fuel tank or permanent
damage may occur.
1. Fill the fuel tank only with a fresh, clean, unleaded regular, unleaded premium, or reformulated automo- tive gasoline with a minimum of 85 octane. DO NOT use leaded gaso-
line. We recommend that you add fuel stabilizer to the gasoline. Use the fuel stabilizer supplied with the unit or purchase Craftsman Fuel
Stabilizer No. 3550. Make sure that the container you pour the gasoline
from is clean and free from rust or other foreign particles. Never use
gasoline that may be stale from long periods of storage in the container.

6. As the engine warms up, move choke control to 1/2 choke posi- tion. When engine runs smoothly,
move choke lever to OFF Position.
NOTE: Allow the engine to warm up for several minutes before blowing snow in
temperatures below 0°F.
How To Start A Warm Engine If restarting a warm engine after a short
shutdown, leave choke at "OFF" and do not push the primer button. Ifthe en-
gine fails to start, follow the Cold Start instructions.
_ ARNING: Never run en-
gine indoors or in enclosed, poorly ventilated areas. En-
gine exhaust contains CARBON MONOXIDE, AN ODORLESS AND
DEADLY GAS. Keep hands, feet, hair and loose clothing away from
any moving parts on engine and snow thrower.
Engine parts, especially the muf-
tier, become extremely hot. Se-
vere thermal burns can occur on
contact. Allow the engine to cool before touching.
Never allow children to operate
the snow thrower. Never allow adults to operate the snow throw-
er without proper instruction.
Keep the area of operation clear
of all persons, particularly small children and pets.
Never leave the snowthrower un-
attended while the engine is run- ning. Anyone operating the en-
gine or equipment must carefully read and understand the operat-
ing instructions.
HOW TO CLEAR A CLOGGED DISCHARGE CHUTE
,_ WARNING: Hand contact

your hands.
Use a clean-out tool to remove snow
from the auger housing.
Release the auger drive lever.
Pull out the key.
Disconnect spark plug wire.
Do not place your hands in the au- ger or discharge chute. Use a
clean-out tool to remove snow or debris.
,_ WARNING: Blockage must
be cleared only after shut-
ting off the snow thrower and only with a clean-out tool, not by hand.
SNOW THROWING TIPS
1. When the handle is raised, the au- ger blades will engage the ground
and the snow thrower will move for- ward. When the auger drive lever is
released, the auger blades will stop. If the blades do not stop, see "How To Adjust The Auger Drive Cable" in the Service And Adjustment section.
2. Most efficient snow throwing is ac- complished when the snow is re- moved immediately after if falls.
3. For complete snow removal, slightly overlap each previous path.
4. Whenever possible, discharge the snow down wind.
The distance the snow will be dis-
5. charged can be adjusted by moving
the discharge chute deflector. Raise the deflector for more distance or
lower the deflector for less distance.
6.
In windy conditions, lower the chute deflector to direct the discharged snow close to the ground where it is less likely to blow into unwanted
areas.
7. For safety and to prevent damage to the snow thrower, keep the area to be cleared free of stones, toys 2. and other foreign objects.
1741476 14
8. When clearing snow from crushed rock or gravel driveways, do not al-
low the auger blades to contact the
driveway. Move the handle down to slightly raise the auger blades.
9. The forward speed of the snow
thrower is dependent on the depth and weight of the snow. Experience
will establish the most effective method of using the snow thrower
under different conditions.
10. After each snow throwing job, allow
the engine to run for a few minutes. The snow and accumulated ice will
melt off the engine.
11. Clean the snow thrower after each
use.
12. Remove ice, snow and debris from
the entire snow thrower. Flush with water to remove all salt or other
chemicals. Wipe snow thrower dry.
DRY AND AVERAGE SNOW
1. Snow up to eight inches deep can
be removed rapidly and easily by walking at a moderate rate. For snow or drifts of a greater depth, slow your pace to allow the dis- charge chute to dispose of the snow as rapidly as the auger receives the
snow.
Plan to have the snow discharged in
the direction the wind is blowing.
[o_o_l
WET PACKED SNOW Move slowly into wet, packed snow. If
the wet, packed snow causes the auger to slow down or the discharge chute be- gins to clog, back off and begin a series of short back and forth jabs into the snow. These short back and forth jabs, four to six inches, will "belch" the snow
from the chute.
SNOW BANKS AND DRIFTS
In snow of greater depth than the unit, use the same "jabbing" technique de- scribed above. Turn the discharge
chute away from the snow bank. More
time will be required to remove snow of this type than level snow.

POWER RATINGS
The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of
Automotive Engineers) code J1940 (Small Engine Power & Torque Rating
Procedure), and rating performance has been obtained and corrected in
accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are
derived at 3600 RPM. Actual gross engine power will be lower and is
affected by, among other things, ambient operating conditions and
engine-to-engine variability. Given both the wide array of products on which engines are placed and the variety of
1741476 17
environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross
power when used in a given piece of power equipment (actual "on-site" or
net power). This difference is due to a
variety of factors including, but not
limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor,
fuel pump, etc.), application limitations,
ambient operating conditions (tempera-
ture, 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 Series engine.
ENGINE
LUBRICATION
Check the crankcase oil level before starting the engine and after each eight
(8) hours of continuous use. See Figure 9. Add S.A.E. 5W30 motor oil as
needed. Synthetic 5W30 is acceptable for all temperatures. Tighten oil fill cap/ dipstick securely each time you check
the oil level.
1. Lift the rear of the snowthrower and tilt the unit forward. In the correct
position, the snowthrower will be setting on the front of the auger
housing.
2. Put an oil drain pan under the oil fill tube (See Figure 10).
OII Fill Cap/Dipstick
NOTE: Oil level must be at FULL mark.
Figure 9
Change the oil every fifty (50) hours or at least once a year if the snow thrower is not used for fifty (50) hours.
HOW TO CHANGE THE ENGINE OIL
To change the engine oil, the engine must be tilted forward and the oil
drained from the oil fill tube. Change oil when the engine is warm.
SPARK PLUG
Check the spark plug every twenty-five (25) hours. Replace the spark plug if
the electrodes are pitted or burned, if the porcelain is cracked, or every 100
hours of use.
OII Fill Tube OII Drain
Pan
Figure10
3. Carefully remove the oil fill cap/dip- stick. Oil will begin to flow into the
oil drain pan,
4. After all the oil has drained from the engine, set the snowthrower in the upright operating position.
5. Fill the engine with S.A.E. 5W30 oil.
Make sure the oil reaches the FULL
mark on the oil fill cap/dipstick. DO
NOT OVERFILL.
NOTE: For extreme cold operating conditions of 0°F and below, use a par-
tial synthetic 5W30 motor oil for easier
starting.
3.
Before installing the spark plug,
coat the threads lightly with oil for easy removal. Tighten the spark
plug to a torque of 15 foot-pounds.
Feeler Gauge
0.030"
1. Make sure the spark plug is clean. Clean the spark plug by carefully scraping the electrodes (do not
sand blast or use a wire brush).
2. Check the spark plug gap with a feeler gauge and reset gap to
0.030" if necessary. See Figure 11.

ADJUST AUGER CONTROL CABLE
The auger control cable was adjusted at the factory. If the auger will not en- gage or disengage correctly, adjust the
auger control cable as follows:
1. Loosen the nut that holds the cable tension spring (See Figure 12).
2. Slide the cable tension spring to- ward the rear of the unit until all cable slack is removed.
NOTE: The auger control cable is properly adjusted when the free
cable slack is removed and there is no tension on the idler arm.
3. Tighten the nut that holds the cable tension spring.
If belt stretch has occured, move the end the auger control cable to the out-
side hole as follows:
1. Loosen the nut that holds the cable tension spring (See Figure 12).
2. Move the cable tension spring to- ward the front of the unit to achieve
maximum cable slack.
3.
Remove the upper end of the auger
control cable from the auger drive
lever.
4. Install the auger control cable in the hole shown in Figure 13.
5. Slide the cable tension spring to- ward the rear of the unit until all
cable slack is removed.
NOTE: The auger control cable is
properly adjusted when the free cable slack is removed and there is
no tension on the idler arm.
6. Tighten the nut that holds the cable tension spring.

HOW TO ADJUST THE AUGER BRAKE
The auger brake is adjusted at the fac- tory to assure safe operation of the
snowthrower. If the auger brake needs an adjustment, follow the steps below:
1. To access the auger brake, tilt the front of the unit up.
2. Make sure the auger drive belt is properly installed. See "How To Re- move The Auger Drive Belt".
3.
Turn the adjuster nut (See Figure 16) in or out until the brake
arm is in contact with the auger drive belt (See Figure 17).
4.
Hold the auger drive lever in the en-
gaged position and push the brake arm down to remove all slack.
