3.4.1 Tensioning the toothed belt (Fig. 4)
CAUTION! Danger of injury!
To check the tension of the toothed belt, switch off the
machine electrically, pull the mains plug and ensure the
machine has actually stopped by pressing the motor pedal.
The machine must not be operated without a belt guard for
the motor.
The tension of the toothed belt should not be too great. Slight thumb pressure
should be able to push the belt through by approx. 5 mm.
A too little or too great toothed belt tension can deteriorate the positioning of the
machine and therefore impair the function sequence.
Tensioning the toothed belt (Fig. 4):
- Release upper and lower retaining screw (1), (2) at the machine upper
part.
- Pull out the motor slightly and tighten the lower retaining screw (2) slightly.
- Tension the toothed belt by swivelling the motor.

CAUTION! Danger of injury!
Danger of pulling in parts of clothing and of hair and danger
of crushing fingers and stitching fingers with needles!
When checking positions with switched-on machine keep
fingers and hands away from moving parts.
Machine with or without pneumatic:
The machine requires a needle position and depending on the sewing drive,
possibly also a reference position.
Reference position:
The reference position must be set in such a way, that the point of the
needle in direction of the insertion stitch closes with the right (inner) edge
of the needle slide plate.
Needle position (with stop in and outside the seam:
The needle position needs to be set in such a way that when the machine
is at standstill and the lifting is open the tip of the needle points in the
direction of the right stitch and the plunger, feed dog, and presser plate
are at one level (the position is located at about 8 mm after the upper
needle turning point).
Notes for sewing drives which have two needle positions:
The needle position mentioned above is position 2 at the sewing drive.
The position 1 at the sewing drive should be set in such a way that when
the machine is at standstill the tip of the needle stands about
3 mm in the direction of the left stitch after the lower needle turning point.
14 BA_325-40D-TP_A9_180704_en
3.5 Intermediate vent ing (Fig. 5)
If an intermediate venting with the knee lever should become necessary with
attached pneumatic venting, it can be mounted on the shaft (1) in its usual
position.
Fig. 5
15 BA_325-40D-TP_A9_180704_en
4 Notes on usage
4.1 Needles and threads
The sewing quality can be influenced to a considerable extent by choosing the
most suitable needles and threads for the material to be sewn. It is
recommended to use controlled GROZ-BECKERT needles system 1717 VRUE
only.
The machine is supplied with size 90 needles.
NOTE: A perfect needle is of great importance for a good sewing result.
Damages of the needle point which often can be made visible under a
magnifier only may deteriorate the sewing result. Replace the needle
in time!
We recommend twisted polyester filament threads of size 80 respectively.
Because of their high strength and ability to slide, combined with a low volume
they are to be preferred over a spun thread.
Guaranteed remark!
This machine has been set and sewn off with genuine
GROZ-BECKERT needles.
No guarantee can be granted if the settings are modified
for using different needle types.
4.2 Inserting the needle (Fig. 6)
ATTENTION!
Switch off machine electrically and confirm that the
machine is really in standstill position by operating the
treadle for the motor control before changing the needle.
Otherwise danger of finger bruises and needle
throughstitches.
The curved needle shape determines its position in the needle lever. Attention
should be paid only to ensure that the needle piston is pushed to the stop in the
channel of the needle lever and that the screw (2) of the needle clamping plate
(1) is tightened well.
16 BA_325-40D-TP_A9_180704_en
Fig. 6
4.3 Threading and thread course
ATTENTION!
Danger of bodily injuries!
Switch off machine electrically and confirm that the
machine is really in standstill position by operating the
treadle for the motor control before threading.
Fig. 6 shows the correct threading by using the thread take-up.
17 BA_325-40D-TP_A9_180704_en
4.4 Filling the Bobbin ( Fig. 7)
Fig. 7 shows how the thread should run when the bobbin is filled. Take care to
avoid too much thread being wound on to the bobbin or the upper and lower
discs of the bobbin being forced apart. Damaged or bent bobbins should be
replaced immediately.
Fig. 7
4.4.1 Inserting bobbin and t hreading bobbin thread (Fi g. 8)
The bobbin (1) can be removed and re-inserted by turning the handwheel, so
that the needle lever is in its highest position. The bobbin retaining flap is
turned back from the bobbin case with a short tug, and then, as a result of
spring pressure, the bobbin jumps so far out of the bobbin case that it can be
easily removed.
When inserting the bobbin, take care that the bobbin thread unwinds from
underneath the bobbin. The start of the bobbin thread is then passed through
the slit on the right side of the bobbin case and held gently against the needle
plate.
After this, the handwheel of the machine is turned a full turn and the needle
thread is held with slight tension, following take-up by the tip of the shuttle. In
this way, the bobbin thread is drawn correctly under the leaf spring.
Needle and bobbin thread are then best slightly twisted and then drawn
together through the needle plate hole towards the back.
18 BA_325-40D-TP_A9_180704_en
Fig. 8
4.5 Thread tension
Depending on thread and fabric, nature and thickness the thread tension is set
by adjusting thread tension.
4.5.1 Thread tensioning spr ing - needle thread (Fig. 9)
The range of movement of the thread tensioning spring (3) can be limited or
extended by slackening the right threaded pin (1) and turning the empty bobbin
(2). The tension of the thread tensioning spring can be increased or reduced by
slackening the left threaded pin (1) and turning the empty pin (4). For this
purpose, you turn the bolt with a screwdriver in the appropriate direction.
Fig. 9
19 BA_325-40D-TP_A9_180704_en
4.5.2 Thread tension - bobbin thread (Fig. 10)
The leaf spring (2) regulates the bobbin thread tension. By turning the flat-head
screw with catch (1), the leaf spring must be adjusted in such a way that when
the bobbin is inserted, and the thread is correctly pulled under the leaf spring
and the bobbin case is released, the latter, together with the bobbin drops
slowly down. A slight pull on the thread might be necessary.
Fig. 10
4.6 Setting upper feed
If non-synchronous functioning of upper and lower feed is required, the setting
of the upper feed can be changed by means of slide (3) and left knurled screw
(4) (Fig. 6)
Excess lining can also be compensated by shorter distance of seams. For that
purpose, actuate right pedal.
4.7 Setting stitch l e ngt h (Fig. 7 + Fig. 11 )
CAUTION! Danger of injury!
Switch off the machine and ensure it is switched off by
pressing the pedal for switching the motor.
Otherwise there is a danger of injury through crushing and
needle stitches.
The stitch length can be set by lifting cover (1). (Fig. 7)
First loosen threaded pin (2), then turn screw lens (1) to the left; the stitch
length becomes larger; or turn to the right and the switch length becomes
smaller (Fig. 11).
After you have set the desired stitch length, tighten threaded pin (2) again.
20 BA_325-40D-TP_A9_180704_en
Fig. 11
4.8 Stitch depth
Stitch depth means the distance between the highest plunger position and the
outer radius of the needle. The plunger forces the sewn item from underneath
into the needle plate opening, so that the needle penetrates the layers of
material to the desired depth.
small stitching depth: - the needle penetrates less deeply into the material
layers of the sewn item
large stitching depth: - the needle penetrates more deeply into the material
layers of the sewn item.
Too little or too great a stitch depth may result in missed stitches or stitching
holes.
4.8.1 Setting the stit ch de pt h (Fig. 2)
Using the stitch depth adjustment knob (3) on the right on the lower arm, the
plunger can be raised or lowered, according to the thickness of the material.
Above this adjustment knob is a plate showing how the knob should be turned,
so that the plunger can be lowered or raised.
Turning the knob clockwise: plunger moves upwards,
needle penetrates deeper.
Turning the knob anticlockwise: plunger moves down,
needle penetrates less deeply.
See also “4.8.2 Digital stitch depth display (Fig. 12)”.
21 BA_325-40D-TP_A9_180704_en
4.8.2 Digital stit c h de pt h display (Fig. 12)
If a digital stitch depth display is mounted, the plunger height is indicated
digitally, thus facilitating the work considerably, especially when the material
thickness changes frequently, because the required plunger height can be reset
easily.
Electric current is supplied through a 9V battery in the housing. To avoid
premature discharging of the battery it is recommended to switch off the display
by means of the flip switch at the housing during break times and when
finishing the work. The units digit indicates one hundredth of a mm, the
hundreds digit indicates a full turn of the regulating knob.
In general: low value - thin material
high value - thicker material
Stitch depth adjustment by 1 digit (= 1 place of the units digit) corresponds to a
plunger height adjustment of 0.01 mm.
When the adjustment knob is turned clockwise to the stop, a figure of between
003 and 006 is displayed.
Fig. 12
4.8.3 Changing the battery (Fig. 12)
a) Bring the switch to 0 position.
b) Open cover on the backside of the housing
c) Change the battery - ATTENTION ! Observe the polarity!
d) Close cover.
22 BA_325-40D-TP_A9_180704_en
4.9 Adjusting plunger (Fig. 1)
The plunger pushes the material through the opening in the stitch plate so that
the needle penetrates the cloth to the required depth; The plunger can be
raised or lowered according to the thickness of the cloth by means of the stitch
depth adjusting knob. A label above this knob shows which way to turn the
knob to raise or lower the plunger.
Turning knob clockwise: Plunger rises needle penetrates deeply
into the layers of fabric.
Turning knob counter-clockwise: Plunger lowers, needle penetrates less
deeply into layers of fabric.
4.10 Plunger lowering (Fig. 6)
For larger sewing material thickening, sometimes the stitch depth of a stitch
should be reduced over a shorter or longer section.
On the stand on the right, the height of the lowering can be specified by
adjusting the scale, from a minimum of 0 mm to a maximum of 3.8 mm.
The plunger lowering can also be switched on at rest or during sewing by
actuating the button (5) on the right of the head. The button lights up when
switched on.
In addition, when plunger lowering is activated, the tension of the thread is
automatically increased by additional thread tension (6).
4.11 Sewing dr ive
The machine is as a rule equipped with the sewing drive selected by you.
Please note the separately enclosed operating instructions for the sewing drive.
There you find notes and the instructions for programming the control including
the motor speed adjustments.
23 BA_325-40D-TP_A9_180704_en
5 Operating the sewing machine
CAUTION! Danger of injury!
Take sufficient care during sewing and observe the sewing
area!
Otherwise there is a danger of injury through crushing and
needle through-stitches.
For machines with 2 pedals: push down the left pedal fully increases the top
feed length (multi-width take-up). With this configuration, motor control is taken
over by the right pedal.
To vent the machine, a pneumatic venting system can be supplied instead of
the knee lever.
When releasing the pedal to switch on the motor, the machine moves to its
position and pneumatic venting takes place.
Pressing the pedal forwards closes the vent and the machine starts to sew.
Fig. 13
5.1 Switch-on
Switch on the main switch on the right underneath the table plate.
With pneumatic lifting, connect the service unit to the compressed air network
(10 bar) or connect the compressor and regulate to 5 – 6 bar.
The lifting is now opened and the sewing machine is ready for operation.
24 BA_325-40D-TP_A9_180704_en
5.2 Inserting and rem ovi ng m a t e rial
With needle in its highest positions operate knee lever to move feed plate and
plunger downwards. At the same time tension of the needle thread is released.
Place the material between stitch plate and feed plate.
The material cannot be removed until the last stitch has been completed, the
needle thread loop has fallen from the hook and the needle is again in its
highest position. Then operate knee lever. When a Stop Motor and electric
lifting are used, positioning will follow automatically after stepping on the back
of the treadle. (See Point “3.4 Motor drive via toothed belt”).
ATTENTION! Do not run machine without material between stitch plate and
feed dog.
5.3 Sewing
The sewing operation must be started on the inside or outside seam of the
lining sleeve. As far as possible, the plunger should be set in such a way that
the needle catches only the first layer of the material to ovoid marks or
throughstitches visible on the outside of the piece.
The stop limit of the plunger, installed on the stitch plate "hammer type" must
be placed sufficiently downwards, 50 that only one or two layers of the material
are caught during the operations.
If the needle penetrates more deeply, the thread might not be drawn enough,
whereupon the looper will not catch correctly the loop of the thread.
The material must be introduced carefully and the lining mustn’t be tightened
excessively.
Any folds on the outside of the material must be smoothed with the fingers.
In order to use as much between the stitch plate and the presser plate as
efficient as possible, we recommend to employ this model equipped with a
needle high positioning motor and an electric lifting device.
Prepare sleeve as usual. But, leave on opening of about 20 cm in the inside or
outside seam of the lining sleeve. Turn sleeve.
Sew inside lining sleeve onto arm hole by means of a plain high-speed sewer,
through the opening in the lining seam. Turn sleeve.
Position pieces.
Put pieces on the arm of the machine. Sew the sleeve lining onto the inside
setting seam at a uniform distance from the edge of the arm hole, so that the
sleeve basting seam is covered.
Turn back the arm hole and check the distribution of lining (when closing the
sleeve, make sure that enough width exists on both sides). To ensure correct
sewing in accordance with respective to the model layout and working
procedure, set the upper feed between the figures 1.5 - 2 of the scale. On the
upper part of the arm hole, the width must be reduced; sometimes no width at
all is required. The upper feed can be set at 0.5 - 1.5.
25 BA_325-40D-TP_A9_180704_en
5.4 Problems during se wing and possible solutions
ATTENTION!
Switch off machine electrically and confirm that the
machine is really in standstill position by operating the
treadle for the motor control.
Otherwise danger of finger bruises and needle
throughstitches.
• Thread breaking
Possible causes:
- sharp edges or grooves in needle guide, take-up lever, shuttle or
needle eye when the machine has been used for a long time.
- The thread between shuttle and bobbin case breaks or is pinched off.
- Too much oil has penetrated the shuttle path
- The bobbin is packed too tight or the bobbin sides are forced apart
because the thread is too tightly wound.
- Bobbin case vent or shuttle bridge are not correctly adjusted.
- The shuttle to needle or needle rise has not been correctly adjusted or
has become displaced, meaning that the thread loop is not always
taken up.
- Thread tension is set too slack or too tight.
Remedy:
- Replace or re-polish the damaged parts
- Dismantle shuttle, remove bobbin case and polish the feed edges of
the bobbin case and shuttle path.
- Using an absorbent thread (cotton thread, core spun thread), sew out
on a remnant.
- Insert new bobbin
- Slowly turn the machine by hand and check whether the loop slides
unimpeded through the shuttle. If not, readjust bobbin case vent or
shuttle bridge.
- Correct shuttle position or loop lift.
- Correct thread tension - check thread line.
ATTENTION! thread course, thread, needle plate with plunger and cloth
retainer, needle and thread tension should always be set
and chosen according to the material to be sewn.

Remedy:
- check settings
- check feed (gearing), if necessary, replace feed
- choose needle and thread to suit sewing material.
• Difficulties during feeding the sewn material (stitch length)
Possible causes:
- Feed incorrectly adjusted
- Unsuitable feed gearing
- Incorrect presser plate take-up
- Bunching of the sewn item on the needle plate, particularly when
cross-seaming.
Remedy:
- check settings, if necessary change feed.
- Check lower side of needle plate, feed and sewing tools for damage, if
necessary replace or re-polish.
- The suitable stitch plate must be selected for thick sewn material –
see “7 variable sewing tools” and “8 optional extras”.
5.5 Incorrect stitches
Incorrect stitches can occur if the needle does not catch the sewing material or
the hook does not take up the thread loop.

6 Machine maintenance
CAUTION! Danger of injury!
Disconnect the machine from the mains and ensure that it
is off by pressing the pedal for switching the motor.
Otherwise there is a danger of injury through crushing and
needle stitches.
The machine must be oiled every day at the points marked in red (oil bottle
enclosed with machine accessories). For this purpose, the housing cover top
right, the lower arm cover bottom left and the head cover must be removed.
Material, fibres and dirt which have accumulated on the moving parts of the
machine, must be removed as they can cause faults and jeopardise the
operating reliability of the machine.
Even the shuttle path should be lubricated with a drop of oil from time to time.
For this purpose there is a hole in the shuttle cover.
