belt
guide
out of
the

and
auger
drive pulley.
To
install
the
auger
drive belt:
1.
Place the new auger drive belt into the groove in
the
auger
drive pulley.
2. Move
one
of the belt
guides
on the back of the
auger
housing (below the
auger

that its
"leg"
is 1/16-inch away from the

to make sure that
the
deflector chute
turns
freely. If it doesn't, loosen
