,_ WARNING: This snow thrower is

capable of amputating hands and feet and throwing objects.

Failure to observe the following safety in- structions could result in serious injury.

TRAINING

1. Read this operating and service instruction manual carefully. Be thoroughly familiar with the controls and the proper use of the 5. snow thrower. Know how to stop the snow

thrower and disengage the controls quickly.

2. Never allow children to operate the snow

thrower. Never allow adults to operate the

snow thrower without proper instruction. 6.

3. Keep the area of operation clear of all per- sons, particularly small children and pets.

4. Exercise caution to avoid slipping or falling 7. especially when operating in reverse.

PREPARATION

Thoroughly inspect the area where the

snow thrower is to be used and remove all doormats, sleds, boards, wires, and other

foreign objects.

Disengage all clutches before starting the engine (motor).

Do not operate the snow thrower without wearing adequate winter outer garments.

Wear footwear that will improve footing on

slippery surfaces. Avoid loose fitting cloth- ing that can get caught in moving parts.

Handle fuel with care; it is highly flam- mable.

a. Use an approved fuel container. b. Never remove fuel tank cap or add fuel

to a running engine (motor) or hot en-

gine (motor).

c. Fill fuel tank outdoors with extreme

care. Never fill fuel tank indoors.

d. Replace fuel cap securely and wipe up

spilled fuel.

e. Never store fuel or snow thrower with

fuel in the tank inside of a building

where fumes may reach an open flame or spark.

f. Check fuel supply before each use, al-

lowing space for expansion as the heat of the engine (motor) and/or sun can

cause fuel to expand.

g. Neverfill containers inside avehicle or

on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from vehicle, before fill-

ing.

h. When practical, remove gas-powered

equipment from the truck or trailer and refuel iron the ground. Ifthis is not pos-

1741476

sible, then refuel such equipment on a

trailer with a portable container, rather than from a gasoline dispenser nozzle.

i. Keep the nozzle in contact with the rim

of the fuel tank container opening at all

times, until refueling is complete. Do

not use a nozzle lock-open device.

j. If fuel is spilled on clothing, change

clothing immediately.

For all snow throwers with electric starting motors use electric starting extension cords certified CSA!UL. Use only with a re-

ceptacle that has been installed in accord- ance with local inspection authorities.

Let engine (motor) and snow thrower ad- just to outdoor temperatures before starting

to clear snow. Always wear safety glasses or eye shields

during operation or while performing an ad- justment or repair to protect eyes from foreign objects that may be thrown from the

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.

FROZEN STARTER

If the starter is frozen and will not turn the engine, follow the steps below.

1. Pull as much starter rope as pos- sible out of the starter.

2. Release the starter handle and let it snap back against the starter. Re-

peat until the engine starts.

Warm engines will cause condensation in cold weather. To prevent possible freeze-up of recoil starter and engine controls, proceed as follows after each snow removal job.

1. With engine off, allow engine to cool for several minutes.

2. Pull starter rope very slowly until re- sistance is felt, then stop. Allow the

starter rope to recoil. Repeat three times.

3. With the engine not running, wipe all snow and moisture from the carbu-

retor cover in area of controls and levers. Also, move the choke control

and starter handle several times.

1741476 13

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

use your hand to clean out the dis- charge chute.

To Clear The Chute:

• SHUT OFF THE ENGINE!

• Wait 10 seconds to be sure that the

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.

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.

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

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.

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.

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".

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).

Hold the auger drive lever in the en-

gaged position and push the brake arm down to remove all slack.

In correct adjustment, there will be

1/4 inch clearance between the brake arm and the auger drive

belt when the auger drive lever is engaged (See Figure 17).
