slowly pour only enough oil into the filler hole to raise
the oil level to the Full mark on the dipstick.
Before Starting
Filling the Engine Crankcase
with Oil
Important Do not overfill the crankcase with oil and
run the engine; engine damage will result. Drain the excess
oil until the oil level on the dipstick reads Full.
The engine comes from the factory with only a few ounces
of oil in the crankcase. Before starting the engine, add oil.
The crankcase holds 21 ounces (0.62 liters) of oil; however,
because there is some oil in the crankcase, do not add the
full amount at one time. Use only a high-quality, SAE
5W–30 or SAE 10 weight detergent oil that has the
American Petroleum Institute (API) service classification
SF, SG, SH, or SJ. For extremely cold conditions (below
0°F or –18°C), use 0W–30 weight detergent oil that has the
American Petroleum Institute (API) service classification
SF, SG, SH, or SJ.
9. Insert the dipstick into the filler neck and rotate the cap
clockwise until it is tight.
Filling the Fuel Tank with
Gasoline
For best results, use clean, fresh, lead-free gasoline,
including oxygenated or reformulated gasoline, with an
octane rating of 87 or higher. To ensure freshness, purchase
only the quantity of gasoline that you expect to use in 30
days. Using unleaded gasoline results in fewer combustion
deposits and longer engine life. You may use leaded
gasoline if unleaded gasoline is not available.
To add oil:
1. Move the snowthrower to a level surface to ensure an
accurate oil level reading.
Important
2. Clean around the dipstick (Fig. 12).
Important Do not use methanol, gasoline containing
methanol, gasohol containing more than 10% ethanol,
premium gasoline, or white gas. Using these fuels can
damage the engine’s fuel system.

Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.

• Fill the fuel tank outdoors, in an open area, and
when the engine is cold. Wipe up any gasoline
that spills.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to
1/2 in. (6 to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
the gasoline to expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
• Store gasoline in an approved fuel container and
keep it out of the reach of children.
• Never buy more than a 30-day supply of
gasoline.

3. Remove the dipstick by rotating the cap
counterclockwise and pulling it out (Fig. 12).
4. Slowly pour about three-fourths of the crankcase
capacity of oil into the crankcase.
5. Wipe the dipstick clean with a clean cloth.
6. Install the dipstick into the filler neck, then remove it.
Note: To ensure an accurate oil level reading, you must
fully install the dipstick.
7. Read the oil level on the dipstick.

Danger
When fueling, under certain circumstances, a
static charge can develop, igniting the gasoline. A
fire or explosion from gasoline can burn you and
others and damage property.
Review the Recommended Maintenance Schedule on
page 17. You may need to perform one or more additional
procedures before or soon after you begin operating the
snowthrower.
• Always place gasoline containers on the ground
and away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
• When practical, remove gasoline-powered
equipment from the truck or trailer and refuel
the equipment with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, not from a gasoline dispenser nozzle.
• If you must use a gasoline dispenser nozzle, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.
Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Operating Controls
• Auger/Impeller Drive Control Lever (Fig. 13)—To

Use a fuel stabilizer/conditioner regularly during operation
and storage. A stabilizer/conditioner cleans the engine
during operation and prevents gum-like varnish deposits
from forming in the engine during periods of storage.
5
Important Do not use fuel additives other than a fuel
stabilizer/conditioner. Do not use fuel stabilizers with an
alcohol base such as ethanol, methanol, or isopropanol.

priming. After pushing in the primer, try to start the engine
before priming again.
Danger
9. After the engine starts, immediately rotate the choke
(Fig. 14) to the 3/4 position. As the engine warms up,
rotate the choke to the 1/2 position. When the engine
warms up sufficiently, rotate the choke to the Off
position.
When the snowthrower is in operation, the
impeller and auger can be rotating and cut off or
injure hands and feet.
• Before adjusting, cleaning, repairing and
inspecting the snowthrower, and before
unclogging the discharge chute, stop the engine
and wait for all moving parts to stop. Disconnect
the wire from the spark plug and keep it away
from the plug to prevent someone from
accidentally starting the engine.
• Use a stick, not your hands, to remove an
obstruction from the discharge chute.
• Stay behind the handles and away from the
discharge opening while operating the
snowthrower.
• Keep face, hands, feet, and any other part of
your body or clothing away from concealed,
moving, or rotating parts.
10. Move the speed selector (Fig. 13) to first gear, squeeze
the traction control lever to the handgrip, and then
release the traction control lever. If the snowthrower
moves forward before engaging the traction drive
control lever or after releasing the lever, see Adjusting

and impeller rotate when you disengage the auger/impeller
drive control lever.
Stopping the Engine
1. Engage the auger to clear any remaining snow from
inside the housing.
Warning
2. Run the engine for a few minutes to dry off any
accumulated moisture.
The auger/impeller may pick up and throw stones,
toys, and other foreign objects, causing serious
personal injury to the operator or to bystanders.
3. Release the auger/impeller drive control lever and the
traction control lever (Fig. 13).
4. Stop the engine by doing one of the following:
• Keep the area to be cleared free of all objects
that could be picked up and thrown by the
auger/impeller.
• Keep all children and pets away from area of
operation.
A. Move the throttle to the Slow position, and remove
the ignition key.
B. Move the throttle to the Stop position.
5. Close the fuel shutoff valve (Fig. 18).
• Adjust the skids to match the type of surface being
cleaned. Refer to Adjusting the Skids and the Scraper
on page 19.
6. Pull the recoil starter with a rapid, continuous, full-arm
stroke three or four times. This helps prevent the recoil
starter from freezing up.
• In snowy and cold conditions, some controls and
moving 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.
7. Wait for all moving parts to stop before leaving the
operating position.
Freewheeling or Self-propel
Drive
• Remove snow as soon as possible after it falls. This
produces the best snow removal results.
You can operate the snowthrower with the self-propelling
feature engaged or disengaged (freewheeling). When you
insert the axle pins through the outer axle holes and not
through the wheel hubs (Fig. 4), the snowthrower
• Always use the Fast throttle position when throwing
snow.
• Overlap each swath to ensure complete snow removal.
16
• Discharge the snow downwind whenever possible.
• If the wheels slip, shift the snowthrower into a lower
gear to reduce the forward speed.
• Do not overload the snowthrower by clearing snow at
too fast a rate. If the engine slows down, shift the
snowthrower into a lower gear to reduce the forward
speed.
• After clearing the snow, let the engine run for a few
minutes to prevent moving parts from freezing. Engage
the auger/impeller to clear any remaining snow from
inside the housing. Shut off the engine, wait for all
moving parts to stop, and remove all ice and snow from
the snowthrower.
• In wet or slushy conditions, maintain maximum engine
speed, and do not overload the engine to prevent
clogging the discharge chute.
• With the engine shut off, pull the recoil starter handle
several times to prevent the recoil starter from freezing
up.
• If the front of the snowthrower tends to ride up, reduce
the forward speed by shifting the snowthrower into a
lower gear. If the front still tends to ride up, lift up on
both handgrips to hold down the front of snowthrower.
• When you are not using the snowthrower, close the fuel
shutoff valve and remove the key.
