SG, SH, or SJ. For extremely cold conditions (below
0°F or -18°C), use 0W-30 detergent oil that has
the American Petroleum Institute (API) service
classification SF, SG, SH, or SJ.
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.
7. Insert the dipstick into the filler neck and rotate the
cap clockwise until it is tight.
Adjusting the Skids and
Scraper
Service Interval:
Yearly
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.
1. Move the snowthrower to a level surface.
2. Check the tire pressure in the tires. Refer to Checking
the Tire Pressure in Setup.
3. Loosen the 4 flange nuts that secure both skids to
the auger side plates (Figure 27) until the skids slide
up and down easily.

4. Support the auger blades so that they are 1/8 inch (3
mm) off the ground (Figure 28).

5. Check the scraper adjustment. The scraper should be
1/8 inch (3 mm) above and parallel to a level surface.
A.
For Concrete and Asphalt Surfaces:
If the snowthrower does not clear the snow close
enough to the pavement, adjust the skids to
lower the scraper; if the pavement surfaces are
cracked, rough, or uneven, adjust the skids to
raise the scraper.
B.
For Gravel Surfaces:
Support the auger blades a few inches (cm) above
the ground, and adjust the skids to prevent the
snowthrower from picking up rocks.
6. To adjust the scraper, loosen the 5 mounting
screws (Figure 28), level the scraper, and tighten the
mounting screws.
7. Move the skids down as far as possible.
8. Tighten the 4 flange nuts that secure both skids to
the auger side plates (Figure 27).
Adjusting the Speed Selector
Adjust the speed selector linkage initially and when the
snowthrower is slow, first gear has no speed, or the
speed selector lever does not move into third gear.
1. Drain gasoline from the fuel tank and the engine
oil from the crankcase. Refer to Emptying the Fuel
Tank and to Changing the Engine Oil.
2. Tip the snowthrower forward and block it so that it
cannot fall.
3. Remove the 4 flange-head bolts that secure the
bottom cover to the frame and remove the cover
(Figure 33).
