ADJUSTMENTS

TO

COMPENSATE

FOR

WEAR

TO ADJUST

THE

CLUTCH

ASSEMBLY: (FIGURE 20)

In

order

to

safeguard

the

motor

and

belt

of

your

machine,

we

have

equipped

it

with

a

specially

designed

clutch

assembly.

This

clutch

has

been

set

at

the

factory

at

the

proper

tension

to

assure

correct

cutting

performance.

Continuous

overloading

or

intermittent

overloading

over

a

long

period

of

time

may

cause

wear

to

the

slip

clutch

parts

and

make

it

slip

too

readily.

To

reset

the

clutch

make

the

following

adjustments:

1.

Remove

the

saw

guard,

the

saw

blade,

the

arbor

bracket

and

the

belt.

(See

Fig.

20).

2.

Remove

the

cotter

pin,

hold

the

motor

shaft

with

a

screw

driver,

(this

shaft

is

crossdrilled

with

4

locating

holes),

turn

the

nut

clock-

wise

1/12

revolution

and

insert

the

cotter

pin

through

the

shaft

hole

which

is

:ocated

90°

from

the

hole

from

which

you

removed

the

pin.

Spread

the

ends

of

the

pin

so

it will

not

slip

out.

3.

Slip

the

belt

over

the

large

pulley

carefully

so

that

the

teeth

on

the

belt

are

engaged

with

those

on

the

pulley.

Slip

the

small

pulley

and

arbor

bracket

into

position.

Be

sure

that

the

teeth

of

the

small

pulley

are

engaged

with

those

on

the

belt.

4.

You

will

notice

that

there

are

4

oversize

clearance

holes

for

mount-

ing

the

arbor

bracket

to

the

motor

bracket.

These

holes

are

for

adjusting

the

arbor

bracket

to

the

proper

location

to

maintain

belt

tension.

Insert

the

4

fastening

serews

through

the

arbor

bracket

into

the

motor

bracket

and

tighten

them

by

hand.

Press

down

gently

with

one

hand

on

the

arbor

bracket,

hold

it in

this

position

to

maintain

a

slight

belt

tension

and

tighten

the

4

screws

securely.

CAUTION:

Do not force the arbor bracket down, gentle pressure

from your hand

will

hold the belt

at

the proper tension.

5.

Mount

the

blade

and

guard

and

try

a

sample

cut.

If

the

blade

still

slips

too

readily,

repeat

the

above

adjustment

until

the

blade

slips

only

when

overloaded.

IF

CLUTCH

DOES

NOT

SLIP:

If

your

saw

blade

will

not

slip

under

extreme

overload

or

abuse,

it

has

probably

become

clogged

with

sawdust

or

other

foreign

material

and

needs

to

be

cleaned.

1.

removing

the

clutch

assembly.
