In
order to reduce
thesizeof
theshipping
carton
and hold
transportation
costs
to a
minimum
the Mounting
Bracket
is
de-
tached from
the
Auger
Assembly.
Position
the
Mounting
Bracket
between
the
Auger
Adapter
P1ates
as shown
in
Figure
10.
hsert
a
spacer in
eachof
the
Adapter
Plates. Bolt
the Mounting
Bracket
to the
Adapter
Plates
with
the
plain
washers
to
the outside and
lock
nuts
at the
inside.
Three round head
bolts are furnished
to
attach the
chute
guides
to the discharge
spout instead
of two as shown in
Figure
14.
InstaII
the bolts at
the
two side
guides
with
the
round
heads to the in-
side. For
ease
of
assembly,
install the
front
guide
boit with the nut and
lock-
washer
to the
inside.
The
heavy duty skid shoes
can be
rotated
from
one side of
the blower
to the other
for
increased
life
when
the leading
edges
wear down.
The shoes can
be
installed
with
the skids
facing either inward
or outward.
If
the
skids
are installed inward
they wiII
pro-
tect
the
cutting edge
by
keeping
it 3/16"
higher
than
the skids
when
they are ad-
justed
to the
"minimum"
clearance
po-
sition"
If
the skids are installed
inward
the nuts
and lockwashers
must
be to
the
inside
to
provide
a
"smooth"
outside
suriace.
If
the shoes
are installed
with
the skids
to
the outside
they can be adjusted
fur-
ther upward if
desired
to
place
the cut-
ting
e$ge
in
direct
contact with a hard
level
surface
such as
a concrete or as-
phalt
driveway. If installed in
this man-
ner the nuts andlockwashers
canbetothe
outside. This
installation is not recom-
mended when
operating
on dirtrgravelor
uneven
surfaces.
The
replaceable
cutting
edge
can also
be
reversed
for increased
life
when
the
leading
side_
wears
down.
Auger
Drive
Chain Adjustment
--
The
idler
block
described
on
page
6,
para-
graph
4,
has
been eliminated.
The
two
auger mounting
hubs
have
four holes
in
an
eccentric
circle
around
the auger
mount-
ing
shaft.
The
hubs also
have
an ori-
entation
hole near
the
shaft.
Chainslack
at
the lower
section should
be heldtobe-
tween
3/8"
and
lf 2" under
normalfinger
pressure
midway
between
the drive
sprockets.
When
adjustment
is necessary,
remove
the
two
bolts from
the right
hand
mount-
ing
hub
and rotate
the hub in
either
di-
rection
until
correct
chain
tension
is
obtained
and reinstall
the two
bolts. lm-
portant
-
To keep
the
ehain in
line
with
the
auger
sprocket,
rotate
the
left
hand
mounting
hub
to locate
the
orientation
hole
in
the
same
position
as
the right
hand
hub.
Turn
the auger
to make
certain
there
is
no interference
with
the housing.
If
interference
is
encountered,
remove
the
two
bolts
from
the right
hand
mounting
hub
and rotate
the hub
in
the
opposite
direction
until
correct
tension
is
obtain-
ed.
Reset
the left
hand hub
to
place
the orientation
hole
in
the same
location
as the right
hand
hub.
Should
the
available
adjustment
on
the auger
mounting
hubs
be
used
up,
the
overall
chain length
can be
decreased
by removing
the offset
(half)
lirk from
the chain.
