Adjusting the Auger/Impeller
Drive Belt
Operating the snowthrower with an auger/impeller drive
belt that slips decreases the snowthrowing performance and
damages the belt. Check the auger/impeller drive belt for
the proper tension after the first operating hour, after every
5 operating hours thereafter. Adjust the belt when
necessary.
