If the auger seems to hesitate when rotating while the engine maintains a constant speed, an adjustment is necessary. 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. Test the snow thrower to see if there is a noticeable difference.
Carburetor
WARNING: If any adjustments need to be made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of muffler, engine and other surrounding heated surfaces.
•Refer to the separate engine manual, packed with your unit, for carburetor adjustment information.
Control Cable
As a result of both the control cable and the drive belt stretching due to wear, periodic adjustments may be necessary.
