See engine manual.

LUBRICATION

NOTE: SAE 10W30 or SAE 5W30 oil is acceptable for

use in cold temperatures if engine is difficult to start.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)

improve starting in cold weather, these multi-viscosity oils

will result in increased oil consumption when used above

32°F. Check your engine oil level more frequently to avoid

possible engine damage from running low on oil.

Change the oil after every 25 hours of operation or at least

once a year if the snow thrower is not used for 25 hours

in one year.

Check the crankcase oil level before starting the engine

and after each five (5) hours of continuous use. Tighten oil

fill cap / dipstick securely each time you check the oil level.

1. Move the snowthrower to a level surface.

2. Clean around the dipstick (Figure 5).

NOTE: Dipstick location may vary depending on engine

type.

3. Remove either side mounted filler cap dipstick or high

oil fill dipstick and wipe it clean.

4. Insert the dipstick into the filler neck and turn clockwise

until fully seated. Then remove the dipstick by turning

it counter-clockwise.

5. Fill oil to "FULL" on dipstick with the recommended oil.

6. Securely screw in the oil filler cap/dipstick.

Filling the Fuel Tank

Fill the fuel tank with fresh, unleaded gasoline (minimum

87 AKI octane rating) (Figure 7).

IMPORTANT: Do not add oil to the gasoline.

IMPORTANT: Do not use E85 blended fuels. This engine

is not E20/E30/E85 compatible. Alternative fuels with

high alcohol content can cause hard starting, poor engine

performance, and may cause internal engine damage.

NOTE: For best results, purchase only the quantity of

gasoline that you expect to use in 30 days. Otherwise,

you may add fuel stabilizer to newly purchased gasoline

to keep it fresh for up to 6 months.

Figure 7

Operation

NOTE: Determine the left and right sides of the machine

from the normal operating position.

• Gasoline is extremely flammable and explosive. A

fire or explosion from gasoline can burn you and

others.

• To prevent a static charge from igniting the gaso-

line, place the container and/or snowthrower on the

ground before filling, not in a vehicle or on an object.

• Fill the tank outdoors when the engine is cold.

Wipe up spills.

• Do not handle gasoline when smoking or around

an open flame or sparks.

• Store gasoline in an approved fuel container, out

of the reach of children.

• Do not tip the snowthrower with fuel in the fuel tank.

The operation of any snow thrower can result in

foreign objects thrown into the eyes, which

can result in severe eye damage. Always wear

safety glasses or eye shields while operating

your snow thrower or performing any ad just-

ments or repairs. We recommend standard safe ty glasses

or a wide vision safety mask worn over spectacles.

IMPORTANT: Know how to operate all controls before

adding fuel or attempting to start the engine.

Checking the Engine Oil Level

1. Move the snowthrower to a level surface.

2. Clean around the dipstick (Figure 8).

NOTE: Dipstick location may vary depending on engine

type.

3. Remove either side mounted filler cap dipstick or high

oil fill dipstick and wipe it clean.

4. Insert the dipstick into the filler neck and turn clockwise

until fully seated. Then remove the dipstick by turning

it counter-clockwise.

5. Fill oil to "FULL" on dipstick with the recommended oil.

6. Securely screw in the oil filler cap/dipstick.

NOTE: Running the engine with a low oil level can cause

engine damage. Always check the engine oil before start up.

NOTE: Running the engine with too much oil may cause

engine damage and excess smoke in the exhaust. Always

check the engine oil level before start up.

NOTE: Remove your glove when you push in the primer

so that air cannot escape from the primer hole.

IMPORTANT: It may not be necessary to use the primer

or the choke if the engine has been running and is hot.

Excessive priming may flood the engine and prevent it

from starting.

4. Pull the recoil starter (Figure 12) or if your snow thrower

is equipped with an electric starter, connect an exten-

sion cord to the snow thrower and plug the other end

into a three-hole grounded 110 volt A.C. receptacle

NOTE: Use only a UL-listed, 16-gauge extension cord

recommended for outdoor use that is not longer than 50

feet (15 m).

The electrical cord can become damaged, causing

a shock or fire.

Thoroughly inspect the electrical cord before plug-

ging it into a power source. If the cord is damaged,

do not use it to start the snowthrower. Replace or

repair the damaged cord immediately. Contact an

Authorized Service Dealer for assistance.

IMPORTANT: Run the electric starter no more than 10

times at intervals of 5 seconds on, then 5 seconds off.

Running the electric starter extensively can overheat and

damage it. If the engine does not start after this series of

attempts, wait at least 40 minutes to allow the starter to

cool before attempting to start it again. If the engine does

not start after the second series of attempts, take the

snowthrower to an Authorized Service Dealer for service.

NOTE: If you pull the recoil handle and feel no resistance,

the starter may be frozen. Thaw out the starter before

attempting to start the snowthrower.

5. While the engine is running, move the choke lever

slowly to the right position.

6. Unplug the extension cord from the power source and

the snowthrower (Figure 13).

Unplug the power cord whenever you are not start-

ing the snowthrower.

1. Rub Area 2. Wear Areas

IMPORTANT: During initial operation there is wear be-

tween the auger blades and the scraper bar. This wear is

normal and to be expected. Maximum performance, both

snow throwing and driving, occurs when there is zero

clearance between these two parts. In order to account

for part variation a small interference is designed into the

parts so they can wear to zero clearance within the first

few minutes of operation (Figure 16).

During initial break-in period of the auger blades it

is normal for the auger blades to build up excessive

heat if not operated in the snow.

Do not operate without snow or water for lubricating

the auger blades. This will cause excessive heat

build up in the auger blades which could cause

damage to the auger blades and scrapper bar.

Preventing Freeze-up After Use

• Let the engine run for a few minutes to prevent moving

parts from freezing. Stop the engine, wait for all mov-

ing parts to stop, and remove ice and snow from the

snowthrower.

• Clean off any snow and ice from the base of the chute.

• Rotate the discharge chute left and right to free it from

any ice buildup.

• With the ignition key in the Off position, pull the recoil

starter handle several times or connect the electrical

cord to a power source and the snowthrower and push

the electric start button once to prevent the recoil starter

and/or the electric starter from freezing up.

• In snowy and cold conditions, some controls and mov-

ing parts may freeze. Do not use excessive force when

trying to operate frozen controls. If you have difficulty

operating any control or part, start the engine and let

it run for a few minutes.

Operating Tips

The auger blades can throw stones, toys, and

other foreign objects and cause serious personal

injury to the operator or to bystanders.

• Keep the area to be cleared free of all objects

that the auger blades could pick up and throw.

• Keep all children and pets away from the area

of operation.

• Do not operate snow thrower if weather condi-

tions im pair visibility. Throwing snow dur ing

a heavy, windy snowstorm can blind you and

be hazardous to the safe operation of the snow

thrower.

• The best time to remove snow is the early morning.

At this time the snow is usually dry and has not been

exposed to the direct sun and warming tem per a tures.

• Slightly overlap each successive path to ensure all

snow will be removed.

• Throw snow downwind whenever possible.

• For extremely heavy snow, re duce the width of snow

removal by over lap ping previous path and moving

slowly.

• Keep engine clean and clear of snow during use. This

will help air flow and extend engine life.

• After snow-throwing is completed, allow engine to run

for a few minutes to melt snow and ice off the engine.

• Clean the entire snow thrower thoroughly after each

use and wipe dry so it is ready for next use.

• Spraying off unit with a hose is NOT recommended.

Clearing a Clogged Discharge

Chute

Hand contact with the rotating auger blades inside

the discharge chute is the most common cause

of injury associated with snow throwers. Never

use your hand to clean out the discharge chute.

To clear the chute:

1. SHUT THE ENGINE OFF!

2. Wait 10 seconds to be sure the auger blades have

stopped rotating.

3. Always use a clearing tool at least 15 inches long, not

your hands (Figure 19).

Storage

STORING THE SNOWTHROWER

Immediately prepare your snow thrower for storage at

the end of the season or if the unit will not be used for 30

days or more.

SNOW THROWER

When snow thrower is to be stored for a period of time,

clean it thor oughly, re move all dirt, grease, leaves, etc.

Store in a clean, dry area.

1. Clean entire snow thrower after each use.

2. Inspect and replace belts, if necessary (See “Replace-

ing the Drive Belt” sec tion of this manual).

3. Be sure that all nuts, bolts, screws, and pins are securely

fas tened. Inspect moving parts for damage, breakage

and wear. Replace if nec es sary.

FUEL SYS TEM

IMPORTANT: It is important to prevent gum deposits from

forming in essential fuel system parts such as carburetor,

fuel hose, or tank during storage. Also, alcohol blended

fuels can attract moisture which leads to separation and

formation of acids during storage. Acidic gas can damage

the fuel system of an engine while in storage.

• Empty the fuel tank by starting the engine and letting

it run until the fuel lines and car bu re tor are empty.

• Never use engine or carburetor cleaner prod ucts in

the fuel tank or permanent damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in min i-

miz ing the formation of fuel gum deposits during stor age.

Add stabilizer to gasoline in fuel tank or storage container.

Always follow the mix ratio found on stabilizer container.

Run engine at least 10 min utes after adding stabilizer to

allow the stabilizer to reach the carburetor. Do not empty

the gas tank and carburetor if using fuel stabilizer.

ENGINE OIL

Drain oil (with engine warm) and replace with clean engine

oil. (See “Changing the Engine Oil” section of this man ual).

CYLINDER

1. Remove spark plug.

2. Pour one ounce (29 ml) of oil through spark plug hole

into cylinder.

3. Pull recoil starter handle slowly a few times to dis trib ute

oil.

OTHER

• Remove safety ignition key; store it in a safe place.

• Do not store gasoline from one season to another.

• Replace your gasoline can if your can starts to rust.

Rust and/or dirt in your gasoline will cause problems.

• If possible, store your snow thrower indoors and cover

it to protect it from dust and dirt.

• Cover your snow thrower with a suitable pro tec tive

cover that does not retain moisture. Do not use plastic.

Plastic cannot breathe, which allows con den sa tion to

form and will cause your snow thrower to rust.

IMPORTANT: Never cover snow thrower while engine/

exhaust area is still warm.

WARNING: Never store the snow thrower with

gaso line in the tank in side a build ing where fumes

may reach an open flame, spark or pilot light as

on a fur nace, water heater, clothes dryer or gas

ap pli ance. Allow the engine to cool be fore storing

in any enclosure.
