3Installation and putting into service
3.1 Unpacking the machine
Strobel machines are supplied either as complete units with head, stand and motor, or
head with motor only, or the head only.
Reel stand, rods and other accessories are packed into the packing.
Make sure that all accessories have been unpacked before throwing away any packing
material.
3.2 Installation
C A U T I O N ! Danger of injury!
Danger of bodily injuries or finger bruises through pulling in of
garments or hairs!
The machine may not be operated without belt guards for head
and motor.
If the machine head is supplied without stand and motor first make the borings into
the table top as shown in the drawing. Mount rods and treadles and electric
connections according to the connecting diagram.
Screw on the motor. The electrical connection must be made according to the circuit
diagram in the online manuals.
Mount the head with the rubber plate (1) to the table top according to Fig. 1 using 3
screws (2), 3 washers (3) and 3 hex nut (4).
Mount the V-belt and tense it according to “3.4.1 Tensioning the V-belt”.
Mount the belt guard.
Mount the lifting and motor operating rods as shown in Fig. 1.
Using a compact motor means to assemble the control box and setpoint device under
the table. Also the connecting rod between setpoint device and pedal has to be
connected.
Make sure that all screws on the stand are tight and retighten them, if necessary.
The position generator must be fitted if available. The correct position to the flange
(handwheel) is marked with a spot of paint. Both clamping screws must be tightened
firmly.
Check positions according to point “3.4.2 Positions of the machine” and adjust if
necessary.

A T T E N T I O N !
Before putting the machine into service make sure that the
electric connecting data on the motor's name plate, mainly
voltage and frequency, correspond to your electric network.
A T T E N T I O N !
The machine must be oiled before first start. The maintenance
instructions according to the operating instructions must be
followed!

12 BA_58_A17_220628_en.doc
3.3 Sense of Rotation
The correct turning of the hand wheel is clockwise in line of vision on the hand wheel.
3.4 Motor drive via V-belts
3.4.1 Tensioning the V-belt
C A U T I O N ! Danger of injury!
When checking the belt tension, switch off the machine at the
mains. Do not operate the machine without the belt guard.
Otherwise there is a Danger of crushing fingers, of injuries to
the body and of pulling in parts of clothing.
The tensioning of the V-belt is carried out by swivelling the motor underneath the
table plate after releasing the retaining nut with SW 24, (1) in Fig. 2.
The V-belt must not be tensioned too much, especially with the stop motor. You
should be able to compress it with light thumb pressure by about 2 cm.
Too little V-belt tensioning can impair the positioning of the machine and therefore
impair the function sequence.
Fig. 2

13 BA_58_A17_220628_en.doc
3.4.2 Positions of the machine
C A U T I O N ! Danger of injury!
Danger of crushing fingers and needle through stitching as well
as pulling in of parts of clothing.
Keep fingers and hands away from moving parts when setting
the position generator and checking the positions with switched-
on machine.
General:
Stop motors require a position generator, which takes the mechanical setting of the
machine from the main screw and transmits this to the control of the motor. With
this, for instance, the thread cutter can always be electrically approached in exactly
the same needle looper position. (Fig. 3)
The correct position of the position generator to the flange is marked with a spot of
paint.
To adjust or to remove, release the two clamping screws (1), Fig. 3. tighten these
firmly prior to commissioning.
Fig. 3
With positioning with plunger reset, the motor reverses after thread cutting for a
certain value, to facilitate the insertion of the sewing matter. This does not affect the
setting of the position generator.

14 BA_58_A17_220628_en.doc
Machine with or without thread cutter:
The machine requires a needle position and, depending on the sewing drive, possibly
also a reference position.
Reference (Fig. 4):
The reference position must be set in such a way, that the point of the needle in
the direction of the insertion stitch closes with the right (inner) edge of the
needle slide plate.
Fig. 4
Needle position (with stop in and outside the seam (Fig. 5)):
The needle position must be set in such a way, that with the machine stopped,
the hook of the thread knife catches the thread loop lying over the looper
securely without touching the looper.
Afterwards check by manually activating the thread cutter.
Fig. 5
Notes for sewing drives which have two needle positions:
The above mentioned needle position is position 2 at the sewing drive.
It is essential that position 1 is set with consultation of the operating instructions
of the sewing drive.

15 BA_58_A17_220628_en.doc
3.5 Motor drive via toothed belt
3.5.1 Tensioning the toothed belt (Fig. 6)
C A U T I O N ! Danger of injury!
Switch off the machine at the mains when checking the belt
tension. Do not operate the machine without belt guard.
Otherwise Danger of crushing fingers, of injuries to the body or
of pulling in of part of clothing.
The toothed belt should not be tensioned too much. You should be able to compress
it with light thumb pressure by about 5 mm.
Too little or too tight toothed belt tensioning can impair the positioning of the
machine and therefore impair the function sequence.
Tensioning the toothed belt (Fig. 6):
- Release the upper and the bottom retaining screw (1), (2) at the upper part of
the machine.
- Pull out the motor slightly and tighten the bottom retaining screw (2) slightly.
- Tension the toothed belt by swivelling the motor.
- Tighten the upper and the bottom retaining screw (1), (2) again.
Fig. 6

16 BA_58_A17_220628_en.doc
3.5.2 Positions of the machine
C A U T I O N ! 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 thread cutter:
The machine requires a needle position and depending on the sewing drive, possibly
also a reference position.
Reference position (Fig. 4):
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 (Fig. 5)):
The needle position must be set in such a way, that with the machine stopped,
the thread knife catches the thread loop lying over the looper securely without
touching the looper.
Afterwards check by manually activating the thread cutter.
Notes for sewing drives which have two needle positions:
The above mentioned needle position is position 2 at the sewing drive.
It is essential that position 1 is set with consultation of the operating instructions
of the sewing drive
Needle position (when stopped within the stitch):
The needle position must be set so that the tip of the needle closes against the
right edge of the needle slide plate facing towards the outward stitch.
At the same time, the thread loop lies under tension across the looper.
The needle position is position 1 at the sewing drive.
