belt, follow the steps below and then proceed to the
specific steps listed under respective sub-headings.
1. Disconnect the chute crank assembly at the discharge
chute end by removing the hairpin clip and the flat

gearbox or other com-
ponents, as a result of
doing so, will NOT be
covered by your snow

Check the condition
of both auger belt and
drive belt every 25
hours of snow thrower
operation. Replace if
either shows signs of
wear and tear.
