Before Starting
Filling the Engine Crankcase with Oil
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 38547 and 38560 holds 26 ounces (0.77 liters) of oil, and the crankcase in model 38592 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.
To add oil:
1. Move the snowthrower to a level surface to ensure an
accurate oil level reading.
Note: To ensure an accurate oil level reading, you must fully install the dipstick.
7. Read the oil level on the dipstick.
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.
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.
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.
Important Do not add oil to the gasoline. 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.
11
Page 12
Important Do not use gasoline that is more than 30
days old.
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.
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.
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.
1. Clean around the fuel tank cap (Fig. 12).
2. Remove the fuel tank cap.
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.
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
Review the Recommended Maintenance Schedule on page 18. 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.

Snowthrowing Tips
Danger
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.
Overlap each swath to ensure complete snow removal.
Discharge the snow downwind whenever possible.
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 up.
When you are not using the snowthrower, close the fuel
shutoff valve and remove the key.
Warning
The auger/impeller may pick up and throw stones, toys, and other foreign objects, causing serious personal injury to the operator or to bystanders.
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.
Adjust the skids to match the type of surface being
cleaned. Refer to Adjusting the Skids and the Scraper on page 19.
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.
Remove snow as soon as possible after it falls. This
produces the best snow removal results.
