2. Designated use

The materials. As a rule such materials are fabrics consisting of textile fibres, but they also include leather. They are used in the clothing, domestic-upholstery and automobile-upholstery industries.

This special sewing machine can also be used to execute so-called technical seams. However, the operator must carry out an assessment of the p ossible dangers (wit h which comparatively unusual and they are potentially of enormous diversity. Depending on the outcome of this assessment it may be necessary to take special safety precautions.

Generally speaking material processed with this special sewing machine must be dry, its thickness when compressed by the lowered sewing fe et must not exceed 10 mm and it must contain no hard objects, since otherwise the operator of the machine would have to wear protective goggles (which cannot at present be supplied).

The seam is gene rally executed with tex tile-fibre sewing thr eads of dimensions up t o 11/3 NeB (cotton thread), 11/3 Nm (synthetic thread) or 11/4 Nm (covering yarn). The use of any ot her threads must a lso be subject to an assessment of the risks involved and the taking of any necessary safety precautions.

The premises in which this special sewing machine is set up and operated must be dry and well-maintained. If it is to be used in premises which are not dry and well-maintained, special precautions may be necessary: these must be the subject of an agreement (see EN 60204-3-1:1990).

As manufactu rers of industrial se wing machines we work on the assumption that personnel working on our machines will be at least semi-skilled, so that they can be presumed to be familiar with all normal operations and with the dangers inherent in them.

5.1 Threading the needle thread

Caution - danger of injury

Turn off the main switch. The needle thread may only be threaded with the sewing machine at a hal t .

–

Thread the needle thread as shown in the illustration.

5.2 Adjusting needle-thread tension

the thread cutter to function reliably when the main tensioner 3 is open. The preliminar y t ension 1 should be set l ower than the main te nsion 3.

–

Adjust preliminary tension 1 by rota t i ng the Knurled nut.

–

After major changes to prelimin ary tension 1 the ma i n tension 3 should als o be adjusted accordingly.

Main tension 3

The main tension 3 should be set as low as possible. The looping of the threads must be in the centre of the material (see fig. a). With thin material excessive thread t ension can cause unwanted gathering and thread breakage.

–

Adjust the main tension 3 so that the stitches are uniform.

Manual

The main tensioner 3 is opened manually:

–

when button 2 i s pressed. The main tensi oner 3 remains open for as long as button 2 is hel d down.

–

when the sewing feet are raised with the knee lever (see chapter 5.8).

–

when the sewing feet are arrested in the up position (see chapter 5.9).
