Checking and Adjusting the
Skids and Scraper
Check the skids and the scraper to ensure that the auger
does not contact the paved or gravel surface. Adjust the
skids and the scraper as needed to compensate for wear.
1. Check the tire pressure. Refer to Checking the Tire
Pressure.
2. Loosen the nuts that secure both skids to the auger
sides until the skids slide up and down easily (Figure 41).

1. 1/2 inch (1.3 cm)
3. Support the side plates so that they are at least 1/2 inch
(1.3 cm) above a level surface.
Important: The auger blades must be supported
above the ground by the skids.
4. Ensure that the scraper is 1/8 inch (3 mm) above and
parallel to a level surface.
Note: If the pavement is cracked, rough, or uneven,
adjust the skids to raise the scraper. For gravel
surfaces, adjust the skids further down to prevent the
snowthrower from picking up rocks.
5. Move the skids down until they are even with the
ground.
6. Firmly tighten the nuts that secure both skids to the
auger sides.
Note: To quickly adjust the skids if they loosen,
support the scraper 1/8 inch (3 mm) off the pavement,
then adjust the skids down to the pavement.
Note: If the skids become excessively worn, you can
turn them over and set the unused side toward the
pavement.
Checking and Adjusting the
Traction Cable
Check and adjust the traction cable after the first 2 operating
hours, then yearly thereafter. If the snowthrower does not
drive in the forward or reverse speeds or it drives when you
release the traction lever, adjust the traction cable.
With the traction lever disengaged, check the pin in the
elongated slot in the left side of the snowthrower above
the tire. There should be a gap of 1/32 to 1/16 inch (1 to
1.5 mm) from the front of the slot to the front edge of the
pin (Figure 42).

2. 1/32 to 1/16 inch (1 to 1.5 mm)
If the left hand (traction) cable is not properly adjusted,
do the following steps:
1. Loosen the jam nut.
2. Loosen or tighten the turnbuckle to adjust the pin until
it is the proper gap from the front edge of the slot.
3. Tighten the jam nut (Figure 43).
