How To Adjust The Belts

The belts will stretch during normal use. If you
need to adjust the belts due to wear or stretch,
proceed as follows.

How To Adjust The Auger Drive Belt

If the snow thrower will not discharge snow,
check the adjustment of the auger drive cable.
See “How To Check And Adjust The Cables” in
the Maintenance section. If the adjustment is
correct, then check the condition of the auger
drive belt. If the auger drive belt is damaged,
replace the auger drive belt. See “How To
Replace The Belts” in the Maintenance section.
If the auger drive belt is loose, adjust as follows.
