3 Installation and putting into service
3.1 Unpacking the machine
The machines of the series 400 are only supplied complete.
The thread stand, oil and other machine tool accessories located with in the
package.
Make sure that all accessories have been unpacked before throwing away any
packing material.
3.2 Installation
ATTENTION!
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.
The electrical connection must be carried out according to the marking of the
cable or the supplied wiring diagram.
Check if all screws on the stand are tight and retighten them, if necessary.
Before putting the machine into service make sure that the electrical connecting
data on the motor's name plate, your electric network and the frequency, and all
other connecting values, e.g. for the air, correspond to the data shown on the
machine and the operating instructions.
Since feed cup opening and some other operations are realized pneumatically,
a compressed air connection of 6 bar is required (see point “2.4 Technical
data”). Regulation of the pressure by means of compressed air conditioner
293.0975 at the stand.
ATTENTION!
Before putting the machine into service make sure
that the electrical connecting data on the motor’s
name plate, your electric network, and all other connecting
values, e. g. for the air, correspond to the data shown on
the machine and the operating instructions.
All rust preventing agents, such as Vaseline and similar agents, have to be
wiped off carefully, particularly from the most important sewing tools.

3.3 Sense of rotation
The correct sense of rotation 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
Caution! 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.
The V-belt must not be tensioned too much, especially with the stop motor. You
should be able to depress 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.
3.5 Positions of the machine
Caution! 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:
The machine requires a pulse generator that is mounted on the main shaft
(handwheel) of the machine and that detects the mechanical position of the
machine and sends it to the control.
The pulse generator has to be mounted on the machine as follows:
The pulse wheel (1) from the encoder must be positioned so that the
outgoing edge (disc transition from "light" to "dark" in the machine direction)
in the sensor (2) when the machine with the needle reaches the front
position (Fig. 2).

10 BA_VTD410EV-SEPC1_A1_140417_en
Fig. 2
To adjust or remove, loosen the two clamping screws (2), Fig. 3. Retighten
them well before restarting.
Fig. 3
The proper position of the position transmitter to the flange is marked with a
spot of paint.

11 BA_VTD410EV-SEPC1_A1_140417_en
Positions:
The machine requires two needle positions and, depending on sewing drive,
possibly also a reference position.
Reference position (if necessary, e.g. sewing drive DC1500-AB322A (Fig. 4)):
The reference position needs to be set so that the tip of the needle
concludes with the outer transport table edge in the direction of the
piercing.
Fig. 4
Needle position (when stop outside the stitch (Fig. 5)):
This needle position is important for inserting and removing the material
and is achieved by stepping back the right pedal (pedal position -2).
The needle position needs to be set so that the tip of the needle
concludes at a distance of 7 mm from the outer transport table edge in the
direction of the piercing. The tip is located thereby over the table.
The needle position is position 2 at the sewing drive.
Fig. 5

12 BA_VTD410EV-SEPC1_A1_140417_en
Needle position (when stop in the stitch (Fig. 6)):
This needle position is important when stopping in the stitch (pedal
position 0), when swiveling in the separating plate of the hold-back device
and for the threading.
The needle position needs to be set so that the tip of the needle
concludes at a distance of 10 mm after the transport table edge in the
direction of the piercing. The tip is located thereby in front of the table.
The needle position is position 1 at the sewing drive.
Fig. 6

13 BA_VTD410EV-SEPC1_A1_140417_en
3.6 Lubrication
First lubrication (see also point “6.1 Checking the oil leve”).
Remove outer and inner machine cover and pour original STROBEL oil
supplied with the machine, from above.
To take off the inner cover first pull out the oil pipe 196.0716 which is plunging
in the oil rising pipe 193.0473 of the pump (Fig. 7).
Fig. 7
The special STROBEL oil (viscosity 46 c St) supplied with the machine should
always be used.
The oiling points are lubricated automatically, thus no maintenance is required
(see also point “6.1 Checking the oil leve/oil quantity”).
When remounting the inner cover make sure that the lower part of the main oil
pipe 196.0716 is pushed into the oil rising pipe 193.0473 of the oil pump
(Fig. 7). Otherwise the automatic lubrication does not work and the
machine will be heavily damaged through blocking of the shafts in the
bearings, etc.
Therefore the instructions should be followed carefully and, after filling
the machine with new oil, the machine should be operated for a short
while and the correct working of the automatic lubrication should be
controlled through the oil inspection glass in the outer cover.

4 Instructions for use
4.1 Needles and threads
Use needle type 134.
Since there are several needle points available for the different materials to be
sewn, choose the most suitable needle point according to the needle
manufacturer's catalogue. Recommended needle type for leather is 134 LR, for
textile material 134 R.
When sewing fixed parts it may happen that the needle eye pastes up and
there is no correct loop formation.
Thicker and hard materials require thicker needles.
Guaranteed remark!
This machine has been set and sewn off with genuine
Strobel needles.
No guarantee can be granted if the settings are modified
for using different needle types.
4.2 Inserting the needle (Fig. 8)
ATTENTION!
Switch off the machine electrically and make sure that the
machine is really in the standstill position by stepping the
treadle for the motor control before changing the needle.
Otherwise DANGER of finger bruises and needle through-
stitches.
Introduce the needle with its horizontal groove pointing downwards, push it to
the rear until it strikes against the needle stop 134.0251 (Fig. 8), then clamp it
by means of the screw 171.0406 (Fig. 9).

16 BA_VTD410EV-SEPC1_A1_140417_en
4.3 Threading and thread courses
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.
Otherwise danger of finger bruises and needle through
stitches.
CAUTION!
The function “Preparation threading” does
not
replace the electrical switching off of the machine during
threading.
This function serves only to ensure that the needle is
already in the correct position when the machine is
switched off.
4.3.1 Threading
Before the actual threading of the machine, the needle point can be brought
into the correct position with the function “Preparation threading”.
The function is activated or deactivated by the button “4” on the V810 operating
control and displayed with an arrow over the button or otherwise with the
“-Stop-” display in the display.
Please see the operating instruction manual for the sewing drive.
4.3.2 Thread courses
Because of the pneumatically controlled gathering device two successive
Asked thread tensions are grown. The front tension 838.0196 operating
normally, the rear thread tension 938.0196 activity occurs when the partition
plate of Gathering device swung and fullness, as is gathered at the toe. For this
shirring a firmer tension is needed to better fix the resulting material folds on
the shoe sole, and can get a good gathering. After swinging the partition plate,
the front is now more normal tension back into activity and that the rear thread
tension is released.
