9. Support the scraper 1/8 inch (3 millimeters) above a
level surface if you use the snowthrower on smooth
pavement.
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.
10. Move the skids down to sit flat on the ground and
tighten the four flange bolts that secure both skids to the
side plates.
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.

3. Fuel tank cap
2. Clean around the dipstick (Fig. 12).
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.
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.
