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

chain

idler

(Fig. 25). Tighten

nut securely

against

idler.

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

speeds

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.
