Operating Instructions 878-M PREMIUM - 02.0 - 02/201832

Operation

Damage to the sewing feet or needle plate possible if the thread is wound on without material.

Lock the top roller in place in the highest position.

ATTENTION

The hook thread is normally wound on when sewing is in progress. However, you can also wind on the hook thread without sewing, e.g. if you require a full bobbin in order to start sewing.

Winding procedure

1. Switch on the sewing machine.

2. Press the foot pedal forwards.

The machine sews and winds the hook thread from the

thread reel onto the bobbin. When the bobbin is full, the machine automatically stops winding. The bobbin lever moves down. The cutter is automatically moved into its basic vertical position.

3. Pull off the full bobbin.

4. Tear off the thread behind the cutter.

5. Insert the full bobbin in the hook ( Replacing the hook thread bobbin, p. 34).

6. Repeat the winding-on procedure with an empty bobbin, as described above.

Fig. 17: Setting needle thread tension

Setting pre-tensioner (1)

Set the pre-tensioner (1) so that it has the lowest tension possible, but so high that, when taking out the sewn material after the preceding trimming (when the tensioners (2) and (3) are switched off), the thread is not pulled out of the pre-tensioner (1). (Pretensioner (1) is not switched off at the top roller lifting).

Setting tensioners (2) and (3)

The machine can be equipped with a lever (4) for the auxiliary tensioner (2) temporary switching off. In this case, two thread tension values can be pre-selected and a good stitch tightening can be achieved when sewing over a varia b l e nu mb er of layers of the sewn material with one seam.

1. Switch the auxiliary tensioner off (2) with the lever (4) and sewn on a smaller numbers of layers.

2. Regulate the thread tension on the primary tensioner (3), until a proper thread interlacing is achieved (see picture p. 36).

3. Switch the auxiliary tensioner on (2) by the lever (4) shifting out and sew on a greater number of layers.

4. Regulate the thread tension on the auxiliary tensioner (2) until a proper thread interlacing is achieved (see picture p. 36).

5. If the machine is not equipped with the lever (4), regulate the tension by both tensioners (2) and (3) at the same time so that their nuts are screwed approximately in the same height.

Advanced maintenance work may only be carried out by qualified specialists. Advanced maintenance work is described in the  Service instructions.

6.1 Cleaning work

Cleaning the machine

Lint and thread remnants should be removed after every 8 hours of operation using a compressed air gun or a brush. When sewing very fluffy material, the machine should be cleaned more frequently.

WARNING Risk of injury from flying particles!

Switch off the machine at the main switch before cleaning the machine.

Flying particles can enter the eyes, causing injury. Hold the compressed air gun so that the particles do not fly close to people. Make sure no particles fly into the oil sump.

NOTICE

Malfunctions can occur due to a dirty machine.

Lint and thread remnants can impair the operation of the machine.

Clean the machine at regular intervals as described in the instructions.

7.14Lubrication

WARNING Skin damage due to contact with oil!

Oil can cause a rash if it comes into contact with skin.

Avoid any skin contact with the oil. If oil has come into contact with your skin, wash the affected areas thoroughly.

All wicks and felt bits of the machine head are soaked in oil at the factory. This oil is conveyed to the reservoir during use. This is why you should avoid filling too much oil during initial filling.

NOTICE

Machine damage possible due to incorrect oil.

An incorrect oil type can cause damage to the machine. Only use oil specified in the operating instructions.

CAUTION Risk of pollution from oil.

Oil is a pollutant and must not enter the sewage system or the soil.

Collect waste oil carefully and dispose of it and oily machine parts in accordance with the applicable statutory regulations.

7.15Sewing test

Conduct a sewing test before starting up the machine. Adjust the machine to the sewing material requirements.

To do this, read the corresponding sections in the  Instructions

for use. Read the corresponding chapters in the  Service instructions in order to make adjustments to the machine if the

sewing results do not conform to the requirements.

WARNING Risk of injury from needle and moving parts!

Switch off the sewing machine before replacing the needle, inserting the thread, inserting the hook thread bobbin, and adjusting the hook thread tension and the thread regulator.

Performing a sewing test

1. Insert needle.

2. Wind on the hook thread.

3. Insert the hook thread bobbin.

4. Thread hook thread.

5. Thread needle thread.

6. Set thread tension to material being sewn.

7. Adjust the thread regulator to the material to be sewn.

8. Set top roller pressure to material being sewn.

9. Set top roller stroke to material being sewn.

10.Set stitch length.

11.Transfer the desired quick function from the keypad to the

additional switch.

12.Start sewing test at low speed.

13.Gradually increase sewing speed until working speed is

reached.

8.3 Controller operating modes

The controller of the 878-M PREMIUM has 3 available operating modes:

• Manual mode (program 000)

• Automatic mode (program 001 - 999)

• Programming/edit mode

Manual mode is the simplest operating mode. There are no sewing programs and no inputs for individual sewing sections.

Changes to the top roller pressure, stroke height, stitch length, thread tension and also the activation of other functions are always implemented immediately.

All the major sewing parameters can be changed manually during the sewing process.

Automatic mode allows for the execution of setups (seam program comprised of only one seam section) or complex seam programs.

Seam programs are divided into individual sections. Each section is assigned its own individual stitch length, thread tension, etc.

Programming mode allows the operator to create a new seam program in a quick and easy manner (P flashes above the program number).

Edit mode can be used to change, delete and copy seam programs.
