SERVICE .

Should your machine require factory service or maintenance

please contact any of the Fischbein authorized distributors or

Fischbein Brussels . Return the warranty card with details concerning your

problems for warranty justification .

They can also give you the best advice on utilization ,oil ,thread and

spare parts .

RECOMMENDATIONS FOR MAX. PERFORMANCE .

Work area.

The MODEL F machine should be operated in an area that allows freedom

of motion for the operator and the unit. The machine’s input end at the feed

dog works quickly and the output end near the thread knife is very sharp.

Other operators should keep out of arm’s reach from the area in which the

machine works. Operators should always wear proper eye protection when

operating the machine and not wear loose clothing or jewelry. Long hair

should be pulled back and tied to avoid getting caught in the machine.

Before you start the machine .

1. Make sure your machine is well connected to an adequate power

supply as indicated on the motor.

The motor is double insulated , so there is no grounding required .

2. Verify that all guards are in place .

3. No special installation is required , but we may recommend you to

place something on the ground to set the machine on when not in use.

4. The machine is shipped to you with some examples of sewn test strips

Examine these carefully to see how proper chain form should look.

5. Use of the Fischbein model 1550 suspension and balancing unit is

recommended. This will allow the machine to be suspended at any

convenient height , ready for use .

6. You may want to try the machine on some empty bags or pieces of

paper to get a feel of how to use it , before you start with filled bags .

FISCHBEINCOMPANY

ED.A10/2001

As you sew with the Fischbein model F .

1. Do not use the machine in very humid environment.

2. Machine mechanism will carry the bag automatically through;

therefore do not either pull , push , or turn the machine .

3. Keep hands and fingers away from the bag moving mechanisms.

( feed dog , presser foot )

4. Only use the machine to close bags of specific thickness. It is not

desined for clothing or very thin plastic bags , (see page 3 , machine

specifications) .

5. A minimum of paper bag strength is required. For plastic bags, a

minimal thickness of 120 µ ( microns ) is necessary , depending on

quality of PE used .

Maintenance .

1. Always use genuine Fischbein parts .

2. Do not use screws other than those indicated in the parts list .

Hardware items on the Fischbein model F systems are not metric .

3. Always use original Fischbein D5 needles .

4. Use a 20 / 4 Fischbein 100 % polyester thread to get the best results .

5. Fischbein Premium Thread ( N° 25010.. ) is an excellent product ,and

available in various colors . With a full 200 gr cone you will sew

around 250 bags ( depending of bag widthness ) .

6. We also recommend that you use other Fischbein products such as :

cleaning agents and crepe paper ( tape ) ; these products were

selected to avoid problems and allow the for maximum efficiency of

the machine .

7. Proper settings for all internal components are made at the factory ,

any change to these settings could cause damage to the machine

mechanism .

HOW TO USE THE FISCHBEIN PORTABLE BAG CLOSER ?

1. Take the machine in your right hand and place your finger over the

start switch placed on the underside of the handle .

2. The switch engages and dis-engages with a positive “ click “ .

Pressing and holding it in will start the machine running , releasing

it will stop the machine .

3. It is recommended that bag top “ gussets “ be formed before sewing

the bag . This will make a stronger and more durable closure .

See fig : 1-3 .

4. Take the top of the bag in your left hand at the right side of the bag .

5. Feed the top of the bag between the presser foot and the throat plate .

6. Press on the switch so that the machine starts running . During the

closing operation , the bag will carried through the sewing gap

correctly by the action of the feeding mechanism .

There is no need to push the machine or pull the bag .

7. When the bag is in the machine , it may be usefull to shift your

left hand to the other end of the bag top to support the bag and

achieve a straight seam .

8. When you reach the end of the bag , let the machine run for a little

to form a short “ chain “ and then gently turn the machine to the

left , enabling the knives to cut the thread .

WARNING !!!!

Keep always your hand away from the presser foot to avoid the danger that

your hand could be caught by the feed dog .

NOTE .

Important to check is the free space available between the top

of the bagged product and the sewing line .

The free space must be sufficient the whole width of the bag to allow

enough material to sew .

When closing net bags or jute bags , a free space between the top of the

product and the sewing line of 10 cm is recommended .

For paper bags , not less than 5 cm is suitable .

Experiment with each type of product and bag material to see how

much space needs to be left , to avoid tearing of the bag .

before threading or adjustment .

Threading .

To thread the machine follow the thread path indicated in Fig:5.1 &5.2 .

1. Pass the thread through the first

and second eyelet ( 11109 ) .

2.Take the thread around the

tensioner stud inserting it between

the two tension discs (11114 ) .

3. Pass it through the thirth eyelet

( 11109 ) close to the needle bar

guarding ( 11101 ) .

4. It should then be passed through the

slotted opening in the needle bar

guard , through the needle bar

( 11500 ) and finally through the

opposite side of the needle bar

guard .

5. Then push the thread through the

eyelet ( 11109 ), to reach the needle

front side .

6. Push the thread through the needle

eye from the front side and pull it

through for about 8 cm .

7. Take a bag or small test piece and

introduce it between the throat plate

and the presser foot , making sure

that the needle is up . Start the

machine and sew it through . This

will provide a “ thread chain “ .

8. The machine is now ready to be

used .

Thread cone replacement .

To install a new cone of thread :

1. Unscrew the wing nut (11805) at the base of the thread stand .

2. Remove the thread clamping bolt (11804) .

3. Take a new cone of thread , place it on the thread clamping bolt

and put it on the thread stand (11815) .

4. Re - attaching the wing nut and tightening it sufficiently. The

cone must not be able to rotate or wobble on the thread stand

Thread tension adjustment .

It should not typically be necessary to change the thread tension unless

you change to a much different thread or are sewing a special type of

material . Consult your dealer or a Fischbein service representative for

questions concerning special thread applications .

-The spring (11115) determines

the tension on the thread when

pulled through the two discs

(11114) .

-By turning the nuts of the

tension discs clockwise , you

will get more thread tension , by

turning in the opposite direction

you will reduce that tension .

-The first nut (11117) , close to the spring (11115) is there to adjust the tension,

the second nut (11116) and the washer spring (11655) , serve to lock the

adjustment .

- The screw (F64038) prevents eventual loss of the nuts (11116&11117) and

has no adjustment purpose .

- Start with minimum tension initially and examine the stitch . If it appears

too loose , gradually tighten the tensioning nut until a proper stitch is

achieved . Be sure to tighten the locking nut when the proper setting is reached.

MAINTENANCE AND SMALL REPAIRS .

WARNING !!!!

Always unplug the machine before starting work .

DAILY MAINTENANCE .

Lubricating the machine in operation .

1. Before closing your first bag be certain to see that the lubrication

mechanism is functioning properly .

2. To speed oil through the machine mechanism you must simply press

the oil pump button 2 or 3 times in succession . You will see the oil

flowing through the feeder tube

as you do . This should be

performed every 2 hours of

machine usage . The wicking

inside the housing carries the

dispensed oil to other moving parts

near the looper and needle bar. Do

not remove the wicking from the

MODEL F. If the wicking (11508)

becomes worn and thin, replace it

immediately.

3. Check the level of the oil pump

regularly . Always fill it genuine

Fischbein machine oil (12800) .

4. Always replace the oil reservoir cap to avoid contaminating the

lubricant.

This could cause the oil lines to plug and prevent lubrication of the

machine parts .

5. We recommend pushing the oil pump while the machine is running to

give better oil distribution inside the machine .

Cleaning of the machine .

Each day , clean the machine of any dust or accumulated debris .

This can easily be done by blowing out the machine cavities with

compressed air or by using a dry bristle brush .

FISCHBEINCOMPANY

The Leader in Bag Closing Technology

REF : 14810F-GB

ED.A10/2001

Sticking particles must be removed by using a small brush .

Do not forget to clean arround the bottom of the machine , especially

around the looper and the knives .

If you are working in a very dusty environment , we recommend this

cleaning operation twice a day . To do that , simply slide open the looper

cover (11102) . Blow out the inside with compressed air . Close the

looper cover and tighten the cover pivot screw (11108) if necessary .

By doing these operations daily , you will increase the life of your

machine .

WEEKLY MAINTENANCE .

WARNING!!!!

Always disconnect the machine from the electrical power

source before performing any maintenance or adjustment

Clean the machine weekly , for a few minutes in a cleaning oil bath .

How to proceed ?

1. Fill in a small tank with cleaning oil

up to 6 cm maximum .

2. Remove looper cover located at the

bottom of the machine and the belt -

pulley cover and handle .

3. Plunge the machine vertically into

the oil so that it is immersed to the

level of the throat plate .

4. Turn the machine manually at the

pulley so the moving parts are

cleaned in the cleaning oil bath .

5. Remove the machine from the bath

and drain any excess of oil from the

mechanism .

6. Your machine is now free of dirt and parts are cleaned up .

7. If necessary you may want to loosen any stubborn dirt or grit with a small

brush and rinse the machine again .

FISCHBEINCOMPANY

The Leader in Bag Closing Technology

REF : 14810F-GB

ED.A10/2001

8. Afterwards you may want to clean the outside parts by using a small oiled

brush . Wipe the machine off with a soft , absorbent cloth .

CAUTION !!!!

For a good job , always use Fischbein cleaning oil (12802) .

Never use benzene or similar aggressive or volatile products . Such products

could dry the oil from critical moving parts and cause extensive damage to the

machine or melt some of the plastic components .

Volatile solvent fumes could present a fire hazard if the machine is run where

such vapors exist .

Check the motor brushes each week to be sure that they are of sufficient

length . When the brushes become too short they may damage the motor.

They should be 6 mm in length at minimum .
