IMPORTANT: Make certain to check for correct adjustment of the shift rod as instructed under “Drive Control and Shift Lever” on page 11, before operating the snow thrower.

Skid Shoe

The space between the shave plate and the ground can be adjusted by raising or lowering the skid shoes.

For close snow removal, as when using on a smooth concrete or asphalt driveway, place the skid shoes in the low position. Use the middle or high position when the area to be cleared is uneven. When operating on gravel, always put skid shoes in the high position. See Figure 13.

Adjust skid shoes as follows:

Loosen, but do not remove, the three hex nuts which fasten the skid shoe to the auger housing.

Raise or lower the skid shoe to desired position.

Retighten the hex nuts loosened earlier.

Repeat on the other side of the snow thrower.

Shift Rod Adjustment

Remove the hairpin clip and flat washer from the shift handle under the handle panel. See Figure 12.

Place shift lever in sixth (6) position or fastest forward speed.

Push shift arm assembly down as far as it will go.

Rotate the ferrule up or down on the shift rod as necessary until the ferrule lines up with the upper

NOTE: Make certain the bottom surface of skid shoe is flat against the ground to avoid uneven wear.
