2. INSTALLATION
2.1 UNPACKING PROCEDURES
Every Fischbein sewing head is packaged to protect the unit during normal shipping, storage and
handling. Each sewing head is packed in a corrugated box with cardboard padding surrounding it.
It is then taped shut. Before the unit is unpacked, inspect the box for any signs of damage incurred
during shipping. After the unit is unpacked, inspect the sewing head itself for damage. Report any
damages in writing to the shipper and to your authorized Fischbein representative. Be sure to
locate your sewing head’s serial number and model number and record these numbers for future
reference. Reading from left to right, the first six numbers that are stamped on the housing
represent the serial number. The next three numbers represent the model number. The model
number and serial number are also printed on the plate attached to the side of the housing.
The sewing head is very heavy and can be awkward to handle alone. For safety of the installers
and the sewing head, a dolly platform should be used to transport the sewing head.
2.2 DRIVE MOTOR RECOMMENDATIONS
A 1 HP or 746 W motor is recommended.
WARNING: MAXIMUM RPM FOR THE SEWING HEAD IS
1800 RPM AND MUST NOT BE EXCEEDED.

FISCHBEIN®MODELS 100 & 101 EMPRESS™ SERIES SEWING HEAD
OPERATOR’S MANUAL
REV. H 2005 / 11 8
2.3 MOUNTING THE SEWING HEAD
Due to the size and weight of the sewing head, a cart should be used to transport it. It is best to have a
couple of installers handling the sewing head. Be sure to hold it by the main housing.
The sewing head is attached to the overarm assembly by a mounting plate, which mounts to the back
of the housing with three hex head bolts (Illustration 2). It is extremely important that these bolts be
securely tightened to the sewing head.
Refer to Illustrations 1 and 2. The mounting plate attaches to the overarm assembly with two
hinges. The hinges allow for easy access to various areas of the sewing head as well as the cooling
fan (optional). When the sewing head is rotated into the closed position, the outer swinging edge of
the mounting plate will come to rest on two jack bolts. The jack bolts are used to provide the needed
support during use and enable the latch pin to firmly hold the plate. The mounting plate is locked into
the closed position with a latch pin, which is pushed in and rotated to secure the mounting plate.
(Illustration 3) The locking rod passes through a hole in the sewing frame and then through one in
the mounting plate, when in the closed position.
Illustration 1
(Shown with Cooling Fan Option)

FISCHBEIN®MODELS 100 & 101 EMPRESS™ SERIES SEWING HEAD
OPERATOR’S MANUAL
REV. H 2005 / 11 9
If the jack bolts are not properly adjusted, the sewing head can vibrate possibly causing damage or
other parts to come loose. The jack bolts must be raised or lowered so that they come into firm
contact with the mounting plate. Both bolts come with a lock nut to keep them in position.
The jack bolts are pre-set at the factory for the mounting plate that accompanies the sewing system.
The jack bolts will only have to be adjusted if they become loose or if replacing the plate. To adjust
the jacks, loosen the lock nuts and turn the jack bolts clockwise for about five turns. Rotate the plate
into the closed position until it comes into contact with the jacks and then use the latch pin to secure
the plate. The pin will probably rotate with ease and not actually tighten when turned. Gradually
keep trying the latch pin, while turning the lower jack in increments, couterclockwise. The ideal
setting for the lower jack is when the latch pin tightens firmly before it has rotated the full 90o.
(Illustration 3) Use the lower lock nut to hold it in position.
Gradually turn the top jack counterclockwise until it comes into contact with the plate, when it is in
the closed position, but not locked with the pin. Unscrew the top jack one additional rotation. Lock
the top jack into position using the lock nut. When the plate is in the closed position and secured into
place, the latch pin will tighten completely before rotating the entire 90oand press firmly on the jack
bolts.

2.7 CONSUMABLES
The Fischbein Company recommends using Fischbein cleaning solvent (ref. 5-101), Rykon
#68 oil (ref. 10200), Fischbein oil filter (ref. 15054) and Fischbein sewing thread. Sewing
heads Model 101 use crepe sewing tape, available in a variety of basic colors and widths.
Seals, gaskets, knife blades, belts and any other part subject to normal wear should be
replaced with genuine Fischbein spare parts. If in doubt, contact your Fischbein
representative.
3. MACHINE ADJUSTMENTS
3.1 THREADING THE SEWING HEAD
3.1.1 LOOPER AND NEEDLE THREAD
1. Lock out compressed air and electrical power so the machine cannot run.
2. Refer to Illustration 6, page 14. Thread the needle as shown. A pair of needle nose pliers may
help in threading small areas.
3. The thread at the needle is laced through from machine’s infeed side towards the needle. Let the
thread stick out 4” (102mm) on the other side of the needle.
4. Ensure that the thread runs properly through the thread-tensioning discs B & C.
5. Thread the looper (F) as shown.
6. The thread at the looper (F) must first go through the top hole and then through the bottom hole.
About 4” (102mm) should be left sticking out of the looper. (Illustration 6).
7. To complete a chain off, a piece of bag material should be placed between the presser foot and
the throat plate before running the machine. Loosen the sewing head drive belt tension by
unlocking the drive motor. (System Illustration, page 6, #7) Turn the pulley by hand in a
clockwise direction so the sewn bag proceeds forward through at least three complete cycles.
This will start the chaining process. Run the system to clear out the test bag material, before
attempting to run a bag through the system. If this procedure is not followed, it will not start a
chain and the machine might break the needle.
8. A Model 101 tape sewing head must have tape between the presser foot and feed dog to operate.
Check the looper to ensure no thread has accumulated around it.

REV. H 2005 / 11 15
3.1.2 FILLER CORD (OPTIONAL)
1. Lock out electrical and pneumatic systems before attempting to thread the filler cord.
2. Follow Illustrations 6, 7 and 8 to thread the
filler cord with the looper and needle thread.
Note that the filler cord does NOT get
threaded through the thread pull off.
3. Once the thread has been threaded through the
Filler Cord Eyelet (Illustration 7), it will be
threaded through the presser foot as shown in
Illustration 8.
4. The bottom of the presser foot is designed with
a channel, which runs from the filler cord hole
to the back of the presser foot.
5. To complete a chain off, a piece of bag
material should be placed between the presser
foot and the throat plate before running the
machine. Turn the pulley by hand in a
clockwise direction so the sewn bag proceeds
forward through at least three complete cycles.
Run the system to clear out the test bag
material, before attempting to run a bag
through the system. If this procedure is not
followed, it will NOT start a chain and the
machine might break the needle.
6. The needle thread should
actually be sewn through the
filler cord. Be sure to leave
about 4 inches (102 mm) of
filler cord (chaining) out past
the back of the presser foot
before running the first bag
through the system.
7. It is very important to keep
the needle thread and the
filler cord separated and not
to let them accidentally twist
together while threading or
running the sewing system.

OPERATOR’S MANUAL
REV. H 2005 / 11 16
3.2 THREAD TENSION ADJUSTMENT
1. Looper thread tension (A):
The tension on the looper
thread must be light and
even as the thread is
pulled with a steady, even
motion. If the tension is
not even, or a large force
is required to pull the
thread, the source of the
problem must be found
and corrected before
running the machine.
2. Needle thread tension (B):
Illustration 9. The needle thread tension is adjusted with the thread tensioner (B). The needle
thread tension should put a noticeable drag on the thread. Tension also varies with stitch length
and thickness of material to be sewn.
This adjustment can be combined with thread pull off positioning (D). On the needle arm, thread
tensioner (C) prevents thread pulled by the thread pull off from sagging too close to the needle.
Tension is very slight and the adjustment is fixed. Factory settings of tension are made for a 4-
ply paper bag with a stitch length of 2.5 stitches per inch (10 mm per stitch) using Fischbein
synthetic thread 12/5, unless otherwise specified when ordered, which is valid in most cases.
Illustration 9

REV. H 2005 / 11 17
3. Thread pull off adjustment
Illustration 10 shows the factory setting. This is suitable in many cases.
For thin materials, distance Xmust be shorter.
For thick materials, distance Xmust be larger.
If the stitch is too loose, try first to adjust with the needle thread tension before shortening the
distance Xof the thread pull off.
Illustration 10

FISCHBEIN®MODELS 100 & 101 EMPRESS™ SERIES SEWING HEAD
OPERATOR’S MANUAL
REV. H 2005 / 11 18
3.3 STITCH LENGTH ADJUSTMENT
The standard factory setting of the stitch length is 3/8” (10 mm per stitch). Other stitch lengths
can be set according to customer requirements. If a change is needed, please follow the
procedure below:
1. Be sure the feed dog is down below the surface of the throat plate, by rotating the drive pulley
clockwise. (Illustration 12)
2. Stand the sewing head on its drive pulley so that no oil can flow out when removing the bottom
cover (C, Illustration 5 and 11). Block the head to prevent it from rotating on its pulley.
3. Remove the oil drain plug (Illustration 11) from the bottom cover (C). The drain hole will
provide access to the socket cap screw (A), used in adjusting the stitch length.
4. With a 3/16” allen wrench, loosen (but do not remove) the socket cap screw (A). (Illustration
11) The screw may fall into the housing if it is removed.
5. The stitch length is changed by moving link (D) (Illustration 11) along the slot in link (B).
Moving link (D) toward the throat plate shortens the stitch. Moving it away from the throat
plate lengthens it.
6. Tighten the socket cap screw (A), but not fully yet.
Illustration 11
(
Bottom Plate View
)

FISCHBEIN®MODELS 100 & 101 EMPRESS™ SERIES SEWING HEAD
OPERATOR’S MANUAL
REV. H 2005 / 11 19
7. To check the stitch length, tilt the sewing head enough to rotate the drive pulley, without
allowing the oil to leak out of the drain hole. Put a sample piece of bag under the presser foot.
Rotate the drive pulley clockwise through ten cycles and remove the bag sample. Calculate the
stitch length and make necessary adjustment to the socket cap screw (A). (Section 3.14.3, pages
37-38, #5)
8. Tighten socket cap screw (A) after obtaining a correct setting. Wrap new Teflon® tape around
the drain plug, and install it back into place.
9. Stitch length can vary between 2 to 4 stitches per inch (6,4 mm to 12,7 mm per stitch).
10. Changing the stitch length also involves re-synchronising the sewing head to the conveyor and
the infeed (see Section 3.14, page 34).
3.4 CORK SEAL REPLACEMENT
1. Referring to Illustration 11 and 12, check the cork seal located between plate (C) and housing
(D), whenever plate (C) is removed.
2. Replace the seal (part number 10093) if it is damaged. Grease can be applied.
