2.4.1 General notes
C A U T I O N !
Work on the sewing machine's electrical equipment or sewing
drive may only be done by electricians!
There is the D A NG E R of a fatal electrical shock.
When working on the electrical equipment, the machine with
the S1 power switch has to be switched off and the power plug
pulled out!
The operating instructions (including safety instructions) of the
sewing machine and sewing drive must be observed!

6 MA_VEB100-6_A4_230102_en.doc
2.5 Mains connection of the machine
2.5.1 Mains structure
C A U T I O N !
The sewing drive may only be connected to an earthed
alternating voltage mains, i.e. with an earth conductor system!
The sewing drive or sewing machine may only be operated with an earth conductor at
a functioning earth conductor system that complies with all local provisions and
regulations.
The protective effect of the earth conductor must not be voided when connecting, for
instance, with extension cords without earth conductors.
Any interruption to the earth conductor inside or outside the sewing drive is
prohibited.
2.5.2 Mains voltage and frequency
C A U T I O N !

3Hints for repair and adjustment
C A U T I O N ! Danger of Injury!
Observe safety and operating instructions before realizing any
maintenance and repair works.
Failure to do so may result in heavy bodily injury.
3.1 Mounting the stitch plate
Stitch plates are set at works and can be replaced easily as complete kit. When
replacing the needle guide the dimensions have to be checked by means of a gauge as
shown in Fig. 5. After removing the needle lever the gauge is mounted to the needle
shaft and senses the needle guides by turning the handwheel.
The stitch plate dial indicator 00392.0517 (Fig. 3) can be purchased as an accessory.
Fig. 3

14 MA_VEB100-6_A4_230102_en.doc
3.1.1 Removing the stitch plate (Fig. 4)
A T T E N T I O N !
Switch off machine electrically.
-Switch off machine electrically, cloth support arm is lifted.
-Swing tape feeding device upwards
-Remove needle and needle lever.
-Remove the thread trimmer's drive unit as described under
“3.9.1 Removing and remounting the thread trimmer drive (Fig. 14)”or pull the
plug only.
-Release stitch plate fastening screws (1) and (2) and remove the complete stitch
plate unit to the front.
Fig. 4
3.1.2 Remounting the stitch plate
Remount the stitch plate in reversed order but make sure that the stitch plate opening
is mounted centrically to the plunger foot and that the stitch plate is mounted
horizontally. Push the stitch plate bow completely upwards until threaded pin (3) (Fig.
4) fits closely to the needle shaft bush.

15 MA_VEB100-6_A4_230102_en.doc
3.1.3 Setting the stitch plate (Fig. 5)
The theoretic needle radius of 41.3 mm should be 0.03mm to 0.05 mm larger at the
left needle guide, 0.01 mm smaller to 0.01 mm larger at the needle glide plate and
0.10 mm to 0.12 mm larger at the right needle guide.
The settings should be realized with a gauge. Deviations may deteriorate the sewing
result considerably and may cause damages or premature waste of the sewing tools.
Fig. 5
3.1.4 Replacing the needle glide plate (Fig. 4 and Fig. 9)
Loosen screw (4) to remove the needle glide plate.
When remounting the needle glide plate make sure that it fits closely to the stitch
plate bridge.
3.1.5 Setting the cloth retainer (Fig. 6)
After replacing the stitch plate check if the cloth retainer is placed centrically to the
plunger. This refers mainly to the roof-shaped cloth retainer to guarantee that the
material is caught perfectly during sewing.
Fig. 6

16 MA_VEB100-6_A4_230102_en.doc
3.2 Loop stroke (Fig. 10)
The loop stroke is the needle's way from its right cups to the point where the point of
the large looper finger is placed above needle center.
3.2.1 Setting the loop stroke (Fig. 7 and Fig. 10)
A T T E N T I O N !
Switch off machine electrically.
At factory the loop stroke is set to 2.8 +0.3 mm (Fig. 10).
Adjustment:
-Screw out universal joint : smaller loop stroke
-Screw in universal joint : larger loop stroke
Thread pitch = 0.5 mm per turn.
Proceed as follows to turn the universal joint shaft (Fig. 7):
-Release screw (1) and push looper (2) to the front.
-Release nut (3) on the looper shaft.
-Release screws (4) in connecting rod head (5).
-Loosen set collar (6) and pull out looper shaft and connecting rod head (5) from
universal joint (7).
Do not release bolt (8)!
The loop stroke is determined by means of a special gauge or caliper gauge.
