3. Remove seven self-tap
screws from rear cover plate
(Fig. 26), and remove
rear cover plate.
4. Loosen
nuts on four
bolts
inside
chassis
securing
transmission
to
chassis,
and
slide
transmission
toward
rear
of
chassis
until
proper
output
chain
tension
is obtained
(Fig. 21). Tighten
four
nuts to
secure
transmission
and re-assemble
all parts.
5. Re-adjust
input chain (section

(D)
CARBURETOR
ADJUSTMENT
(Fig. 28)
Never
make
unnecessary
adjustments.
Factory
re-
commended
settings
are correct for most applications.
If adjustment
is required,
proceed as follows:
1. Close high speed adjusting
needle finger
tight, and
re-open one turn.
2. Close idle adjusting
needle finger tight, and re-open
one turn.
3. Start
engine
and move throttle
control
to "FAST"
for high speed adjustment.
4. Turn
high speed adjusting
needle forward
or back
I/S
turn at a time until
engine runs moothly.
NOTE:
Always allow several
seconds
between
adjust-
ments for the carburetor
to adjust
to new setting.
5. With engine
running
smoothly,
turn high speed ad-.
justing
needle out (counter-clockwise)
I/S
turn. This
may
add
a slight
roughness
to engine,
but
it is
advisable
to obtain
a slightly
rich mixture
for opera-
tion
under
load.
6. Move throttle
control
to "SLOW"
position
for idle
adjustment.
7. Turn
idle adjusting
needle
in or out
I/S
turn
at a
time
until
engine
idles smoothly.
IMPORTANT:
Never
attempt
to
change
maximum
engine
speed.
Bypassing
the governor to obtain higher

may cause severe
engine
damage.

RECOMMENDED
OPERATING
PROCEDURES
1. The
most
efficient
operating
speed
for
snow
re-
moval is dependent
on depth
and weight
of snow.
Experience
will
establish
the most efficient
operat-
ing speeds for particular
snow conditions.
2. Recommended
patterns
of throwing
snow are illus-
trated
in Fig. 29 and 30. In the situation
illustrated
in Fig. 29, the discharge
chute should be positioned
to
throw
the
snow
with
the
wind,
requiring
the
operator
to reverse the chute
position
at the end
of each run.
3. In Fig. 30, snow removal should begin in the centre
of area
to
be cleared.
Chute
position
should
be
reversed at end of each run.
4. Use of tire chains is optional.
They may be removed
for snow removal from hard surfaces such as black-
top or concrete.

TO ASSEMBLE
TIRE
CHAINS
TO TIRES:
(a) Place
chains
on ground
behind
each
wheel,
so
that
ends with
connector
links
are furthest
from
wheels
(Fig. 31).
(b) Pull
unit
backwards
onto
chains
so that
wheels
rest in middle
of each chain (Fig. 31).
(c) Wrap chain around wheel and connect
inside link.
Make sure there are no kinks in the cross links or
side links, and that the links are snug against
the
tire.
(d) Pass outside
connector
link
through
end link
on
opposite
end of chain (Fig. 32).
(e) Turn
connector
link
back,
and
hook
the
end
of connector
link over the side chain to lock into
place as shown (Fig. 33).
NOTE:
If the chain does not appear to be long enough
to allow connector
link to be turned
back 180°, check
for kinks in either
the side chain or one of the cross
chains.
To remove
tire chains
(Fig. 33): Use a screwdriver
to
unhook
connector
links
on
inside
and
outside
of
wheels.
