Part 3: Service Instructions
1. Notes prior to adjustment
These servicing instructions describe the
adjustments to the sewing unit in the appropriate
order.
Here it is to be noted that the various adjustment
positions are interdependent. It is therefore
essential that the adjustments be made in the order
described.
Attention Danger of Breakage!
After disassembly and prior to restarting the
sewing unit, the required adjustments must
be made as described in these instructions.
The sewing unit must not be started with the
wrong direction of motor rotation.
Attention Risk of Injury!
Should adjustments have to be made in the
area of the needle and the needle not be
absolutely necessary to these, it should be
removed to avoid injuries.
The main switch should always be turned off.
The only exceptions are those adjustments
which must be made with testing, setting or
sewing programs from the control unit.
Attention!
With some adjustments it is necessary to move the
transport carriage manually.
This is possible with the main switch OFF.
When the main switch is ON, e.g. when the testing
program is to be used, the step motor is under
current and its braking effect stops manual
movement. In this case the fuse 3 for the step
motor must be removed from the control panel.
For all adjustments to parts forming stitches a
faultless needle must be used.
Upon request you will receive the following
adjustment gauges:
Order no. Application
933 80207 Dail gauge
933 80193 Angle for the looper symmetr y setting
933 80194 Indicator for the looper symmetry
setting
933 80200 Feeler gauge for the thread take-up
disk
933 80203 Gauge for the hook drive housing
933 80221 Gauge for the rocker bolt in the hook
drive
An adjustment disk in the machine head has the
notches A,B,C and D. An arresting pin, order no.
211700, for locking into the various adjustment
positions can be found in the package with the unit.
In conjunction with the letters on the handwheel the
arresting pin can be pushed into one of the notches
through a hole.
2.
Transport carriage
Caution in the area of moving machine par ts
- Risk of Injury -
The transport carriage is guided on the extension
pipes at the front by the ball sleeves 2 and at the
back by the track rollers 1.
They have been set tight at the factory. To remove
axial play only loosen the excentrically bearinged
lower rollers 1 and set tight. Check for ease of
movement.
The transport carriage is advanced by the step
motor for the following speeds: Stitch condensing,
Normal stitch length and transport carriage return.
Through a coding on the material stopper it is
possible by primary seams to reduce return speed
for a partial or complete run according to the rail
form. See 5.1.10 of the Microcontrol summar y.

2.1_ Right End Position
If the right position has been set with the L<-W->R
key, right diode bright, then the carriage will stop at
the right.
The distance between the middle of the cylinder 4
and the middle of the needle should be 212.5_mm
in the right end position.
Main switch off
- Risk of Injury -
Preliminary Adjustments
– The b417.6 selector switch on the back of the
control unit front panel must be set closed for
1000 mm and open for 1250 mm, appropriate to
the rail length used.
– With the main switch Off, set the transport
carriage with the bracket 6 over the switch b7.
There must be a gap of 0.5 mm between the
bracket 6 and the switch b7.
Also between timing belt clamp 9 and switch b8.
– With lit right diode and a long tap of the
L<-W->R key, set the parameter value to 0 with
the numeric keypad.
– A gap of 105 mm must be set between the cast
guide 8 under the machine arm and the clamp
piece 5.
– In order to avoid a collsion of the transport
carriage with the machine head during a
malfunction of the step motor, the safety
stopper 7 is to be set at a distance of 25 mm
from the machine head at the right.
The distance of the safety stopper 11 at the left
behind the machine head should be 45 mm at
1000 mm sewing length and 58 mm at 1250 mm
sewing length.
– Switch b8 serves as a safety switch. Its
distance from the mounting plate 10 should be
53 mm by 1000 mm sewing length and 55 mm
by 1250 mm sewing length.
All setting measurements can be seen together
in the following dimension sketch.
For the fine adjustment of the right end position
see the next page.
