UP

When

setting

up

the

machines, see

that

the

rubber

insulating

bushings

are

in

place

in the

four

holes

in

the

machine

bed.

Place the

felt

pads

over

the

four

studs in

the

corners

of

the base, then set the

machine

on

the base,

with

the studs

through

the

holes

in the

rubber

bushings.

CAUTION: After setting

up

the machine, do not

run

it

until

it

has

been

oiled

as

instructed below and

on

pages 5, 6 and

7.

SPEED

The maximum

speeds

recommended

for

these machines

are

as

follows:

Machines 2

47-4

and 2

47-6

.

.....

3800

rrvolutions

per

minute

Machines

247-5

and

247-7

.....

.

3600

rnvolutions

per

CAUTION

--These machines

should

be

operated

at

moderate speeds

for

the first

few

days,

after

which

they can

be

operated

at

maximum speeds

depending

on

the nature

of

the work being sewn.

TO

OIL

THE

MACHINES

These machines

are

each

equipped

with

an

oiling

system

which

automatic-

ally

delivers

the

required

quantity

of

oil

to

all

principal

bearings.

A

connect-

ing

rod

scoop

takes

oil

from

the

reservoir

and

lubricates,

by

splash,

the

various

bearings

inside

the

machine

arm. Some

of

this

oil

is

distributed,

through

pipes

and

wicks,

to

the

principal

bearings

outside

the

machine

arm.

TO

INSURE OPERATION

OF

THIS

OILING

SYSTEM,

THE

FOLLOWING

INSTRUCTIONS MUST

BE

CAREFULLY

OBSERVED.

FAILURE

TO

DO

THIS

WILL

RESULT

IN SERIOUS

DAMAGE

TO

THE

eye.

Rough

or

uneven

thread,

or

thread

which

passes

with

difficulty

through

the

needle

eye,

will

interfere

with

correct

stitching.
