Control Cable
As a result of both the control cable and the auger drive belt stretching
due to wear, periodic adjustments may be necessary. If the auger
seems to hesitate when rotating, proceed as follows:
The upper hole in the control handle provides for an adjustment in
cable tension. To adjust, disconnect the end of control cable from the
bottom hole in the control handle and reinsert it in the upper hole.
Insert the cable from the outside as shown in Figure 15.

Test the snow thrower to see if there is a noticeable difference. If
after the adjustment to the control cable the auger still hesitates when
rotating, see Belt Replacement for instructions on replacing the belt.
Chute Assembly
Refer to the Assembly section for instructions on adjusting the chute
assembly.
