3. Remove the dipstick by rotating the cap
counterclockwise and pulling it out (Fig. 12).
9. Support the scraper 1/8 inch (3 millimeters) above a
level surface if you use the snowthrower on smooth
pavement.
4. Slowly pour about 3/4 of the crankcase capacity of oil
into the crankcase.
Note: The scraper should be higher than 1/8 inch
(3 millimeters) above the pavement if it is cracked, rough,
or uneven. Setting the scraper too low may result in
damage to the snowthrower that is not covered by the
warranty.
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.
10. Move the skids down to sit flat on the ground and
tighten the 4 flange bolts that secure both skids to the
side plates.
7. Read the oil level on the dipstick.
Before Starting
8. If the oil level is below the Add mark on the dipstick,
slowly pour only enough oil into the filler hole to raise
the oil level to the Full mark on the dipstick.
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 in models 38079 and 38559 holds 26 ounces
(0.77 liters) of oil, and the crankcase in model 38087 holds
28 ounces (0.83 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 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:
Important
1. Move the snowthrower to a level surface to ensure an
accurate oil level reading.
Do not add oil to the gasoline.
Important Do not use methanol, gasoline containing

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.
Do not use gasoline that is more than 30
Danger
1. Clean around the fuel tank cap (Fig. 12).
2. Remove the fuel tank cap.
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.
3. Fill the fuel tank with unleaded to within 1/4 to 1/2 inch
(6 to 13 millimeters) from the top of the tank. Do not
fill into the filler neck.
• 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.
Important Do not fill the fuel tank more than 1/4 inch
(6 millimeters) from the top of the tank because the
gasoline must have room to expand.
4. Install the fuel tank cap and wipe up any spilled
gasoline.
Checking the Tire Pressure
Check the pressure of the tires because they are
overinflated at the factory for shipping. Reduce the
pressure equally in both tires to between 12 and 15 psi
(82 and 103 kPa).
Reviewing the Maintenance
Schedule
Danger
Review the Recommended Maintenance Schedule on
page 19. You may need to perform one or more additional
procedures before or soon after you begin operating the
snowthrower.
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.
• 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.
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.

Operating the Power Shift
Feature
Move the wheels to the rear Power Shift position in heavy
or drifted snow. Leave the wheels in the front position for
light snow or for transporting the snowthrower.
Important Ensure that the auger and impeller do not
rotate while the auger/impeller drive control lever is in the
Disengaged position. Stand in the operating position and
look around to the side of the auger housing (Fig. 20). A
large screw head on the side of the auger housing rotates
when the auger and impeller rotate (Fig. 20). If the auger
and impeller rotate while the engine runs and the
auger/impeller drive control lever is disengaged, stop
the snowthrower immediately. Refer to Adjusting the
Auger/Impeller Drive Belt on page 22. If the problem
persists, take the snowthrower to an Authorized Service
Dealer for service.

Snowthrowing Tips
Freewheeling or Self-propel
Drive
Danger
You can operate the snowthrower with the self-propel
feature engaged or disengaged (freewheeling). When you
insert the axle pins through the outer axle holes and not
through the wheel hubs (Fig. 23), the snowthrower
freewheels. When you insert the axle pins through the holes
in the wheel hubs and the inner axle holes (Fig. 23) and
engage the traction control lever, the snowthrower propels
itself.
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.

• 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.
• In wet or slushy conditions, maintain maximum engine
speed, and do not overload the engine to prevent
clogging the discharge chute.
• 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.
• If the wheels slip, 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.
• With the engine shut off, pull the recoil starter handle
several times to prevent the recoil starter from freezing

Adjusting the Skids and the
Scraper
For Gravel Surfaces:
Support the auger blades a few inches (centimeters) above
the ground, and adjust the skids to prevent the snowthrower
from picking up rocks.
Adjust the skids and the scraper initially and then as needed
to ensure that the auger does not contact the paved or gravel
surface. Also, adjust them as needed to compensate for
wear.
8. To adjust the scraper, loosen the carriage bolts that
secure the scraper to the auger housing (Fig. 27), level
the scraper, and tighten the carriage bolts.
1. Stop the engine and wait for all moving parts to stop.
9. Move the skids down as far as possible.
2. Move the snowthrower to a level surface and shift the
wheels to the front position.
