8. Install the belt by reversing the removal process.
9. Check and adjust the cable bracket any time the auger belt
or auger cable have been replaced;

stretched a total of .080”.
9b. With the auger control bale released, the cable should
be slack.
9c. Loosen the bracket bolts and slide the bracket to tighten or loosen the cable.
10. Install the belt cover and test the operation of all features of the snow thrower before returning it to service.
