DESCRIPTION

1-1. GENERAL

Your new

Maimin

"POWR"

straight

knife

machine

is

delivered

ready

for

operation.

It

is

merely

necessary

to

connect

it

to

an

electrical

outlet

of

the

correct

voltage,

oil

it, and

then

begin

cutting. The

straight

knife

machine

can

be

used

for

cutting

various

types

of

materials

from

a few

ply

to

the

full height of

the

standard.

However,

for

best

results,

it

is

recommended

that

the

minimum

height

of

the

lay

be

no

lower

than

the

bottom

of

the

cutting

blade

at

its

high-

est

position.

On

the

left

side

of

the

sharpener

you

will

note a

lever -the

Edge

Control

Arm

(Key

No.

K136B)* - which

permits

sharpening

of

either

a rough

or a smooth

edge on the

blade

for

cutting

different

types

of

materials.

The

presserfoot

leg

(Key

No.

K10)

acts

as a pro-

tective

guard

for

the

operator

so

that

it

should

be

down

at

all

times.

The

presserfoot

should

lie

lightly

on top of

the

lay

when

cutting

in

order

to

prevent

the

material

from

vibrating.

SHARPENING STONES AVAILABLE

There

are

three

different

grits

of

sharp-

ening

stones

(Key

No.

K15)

available

for

use

in

this

machine:

#60

grit -coarse.

Recommended

for

hard

and

coarse

materials.

Can

be

used

on

ZZT

and

ST

blades.

syn-

thetics

and cotton. Can

be

used

on

all

blades.

#150

or

difficult

materials.

The

and

release

it.

Sharp-

repeated a number

of

times

to

sharpen

the

in-

itial

edge on a new

blade.

Thereafter,

it

will

only

be

necessary

to

sharpen

once

or

twice

to

renew

the

edge.

(d) Note: Do NOT

press

the

presserfoot

trigger

when

sharpening

as

this

will

TO

OIL

Oil the machine daily

as

noted above. Be

sure

to

use

either

Maimin

oil

or

a good

grade

of

"30

weight" oil.

Do

not

use

sewing machine

oil

or

any

other

light oil

as

they

are

not

de-

signed to give the

lubrication

needed

for

the

cutting machine.

All new machines have

grease-

sealed

ball

bearings

which

require

no

lubrica-

tion.

3-3.

TO

CLEAN

STONES

After

repeated

use,

the

sharpening

stones

bef'ome coated with oil and

dirt

and

do

not

sharp-

en the blade effectively. To

remove

this

coat-

ing,

spray

Maimin Stone

Cleaner

directly

onto

the stone

rims.

Or

put a little

cleaning fluid on

a toothbrush, and

scrub

the

stone

rims.

Be-

cause

some

of the cleaning fluid may

get

on the

gears

near

the

stones,put

a few

drops

of oil on

the

gears

under

the

Carrier

Block (K43)

after-

wards.

3-4.

TO

CHANGE

STONES

To

remove

the

stones,

use a screwdriver

in the

slotted

screw

head underneath the

stones

and

turn

in the

direction

as

shown below.

Note:

that

the

stone

screws

unloosen by

turning

in

opposite

directions.

To

put on new

stones,

tighten by turning the

stone

screws

in

reverse

direction

of

that

shown in the

diagram.

TO

REMOVE

STONES

3-5.

TO

CHANGE

BLADE

The

blades

used

in your model "K"

ma-

chine

must

have the

"cut-out"

in

the

blade

as

illustrated

in the

diagram

below,

or

the

stones

will

be

damaged and

the

blade will not

be

sharp-

ened

properly.

To

remove

the blade, lower the blade to

its

bottom position by turning

fibre

knob (K220)

and

raise

the

presserfoot

leg (KlO). Unlock the

knife bolt and nut

(K239)

with the knife key.

Slide blade out, and

clean

inserts.

Slide the new

blade up through the

inserts

until

its

"T"

-shaped

shoulder

is

firmly

against

the knife locking bolt.

Hold the lower

part

of the blade up and

against

the back of the

inserts.

Lock the knife

secure-

ly. Always

use

genuine Maimin blades with the

patented

"T"

slot.

"T"

SLOT

Always tighten the knife locking bolt and

nut

before

running

the

machine to

prevent

damage

to the

crosshead

and gibbs.

Before

in-

stalling

a new blade, the bottom edge should

be

sharpened

on an oil

stone

to

prevent

ravelling

and to

insure a clean

cut on loosely woven

fabrics.

For

very

soft

or

very

hard

materials,

it

is

also

recommended

that

the bottom

front

corner

of

the

blade be rounded slightly.

3-6.

TO

CLEAN

INSERTS

The

inserts

(K253) which guide the knife

in

the

standard

must

be

cleaned

occasionally

and

whenever

the

knife

is

changed.

Otherwise

dirt

collected

in

the

inserts

can

cause

the knife

to cock and not

sharpen

properly.

Clean the

inserts

by

sliding the

saw-tooth

slot

cleaner

(or

bottom

back

corner

of

the blade )

up

and

down the

back

of the

inserts.
