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 restar ting 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 par ts 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 symmetry 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.

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 factor y. 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.
