LUBRICATION

(Figs.

1 -

5)

For

the

lubrication

of

the

machine,

only

a

good

quality

sewing

machine

oil

should

be

used.

In

order

to

insure

proper

function

of

the

machine

and

to

prevent

any

excess

wear

of

the

moving

parts

and

bearings,

the

machine

should

be

oiled

regularly.

In

case

of

continuous

use,

it

should

be

oiled

even

more

often

if

it

is

used

to

produce

long

seams

and

run

steadily.

is

lubricated

by

oil

pumped

from

the

hook

saddle

reservoir

while

the

machine

operating.

The

amount

of

oil

received

by

hook

raceway_

is

very

important.

To

check

this,

first

remove

bobbin

case.

Then

with

the

machine

running,

hold

a

small

piece

of

white

paper

near

the

hook

for

about

10

seconds.

A

distinct

spray

of

oil

should

be

visible

on

the

paper.

If

there

is

no

trace

of

oil

or

an

excess

of

oil

on

the

paper,

proceed

with

the

following

steps:

1)

A

short

test

run

of

at

least

a

minute

SPEED

Maximum

speed

for
