NOTE: Make sure to remove the piece of wood blocking the impeller.
Check the auger drive belt adjustment. With the auger clutch lever in the disengaged position, the top surface of the new belt should be even with the outside diameter of the pulley.
To adjust, disconnect ferrule from brake bracket assembly. Thread ferrule in (towards idler) to increase tension on belt, or out to decrease belt tension.
NOTE: The brake puck must always be firmly seated in the pulley groove when auger control is disengaged.
CAUTION: Repeat the “Testing Auger Drive Control” from the Assembly and
