AUGER CLUTCH

The auger will not turn unless the auger clutch is 
engaged. The auger must stop within 5 seconds after 
the auger clutch is released.

The clutch cable must contain some slack when 
you disengage the clutch lever for the auger to stop 
properly.

If the auger no longer turns when the auger clutch is 
engaged or if the belt slips under load, the auger cable 
or belt may have stretched. This can be compensated 
for by adjusting the auger clutch cable.

The upper hole in auger clutch lever provides for 
an quick adjustment method. To adjust, unhook and 
move the clutch cable to the upper position. Insert the 
cable from the outside. 

The cable adjuster link found under the spring cover 
provides further adjustment options if required.

1.     Slide up the spring cover and unhook the spring 

from the adjuster link.

You can pull up the adjuster link and cable to make 
unhooking the spring easier.

2.     Move the Z-bend to a higher or lower hole on the 

adjuster link as needed to obtain proper auger clutch 
adjustment. 

3.     Hook the spring to the adjuster link and slide the 

spring cover over the adjuster link.

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, replace the 
auger belt.
