Risk of injury due to the machine being started again inadvertently.
Oil holes marked in red are provided on the cover and on the machine body. The
machine should be oiled at these points about two or three times per month, One drop
of sewing machine oil per oil hole is sufficient.
Attention:
Make sure that you don't too use too much oil, as this can result in the material
becoming soiled.
About every two months, the covers on the looper drive and the skip stitch gears
should be taken off, any excess oil removed, and the individual lubrication points of
the bearings, also marked in red, should be oiled. Also, from time to time, the presser
feet under the stitch plate and the plunger shaft (rib shaft) should be lightly oiled.
Only use sewing machine oil to lubricate the machine.
The time intervals given above relate to single-shift operation.
Disposal of the machine
Correct disposal of the machine is the customer's responsibility.
The materials used on the machine are cast iron, steel, aluminium, brass and various
plastics.
The electrical equipment is made of plastics and copper.
The machine must be disposed of in accordance with the locally applicable
environmental protection regulations. It may be necessary to employ a specialist firm
for this.
Make sure that any parts that have lubricants adhering to them are disposed of
separately in accordance with the locally applicable environmental protection
regulations.

10
Assembly of the machine
Switch off the machine!
Risk of injury due to the machine being started again inadvertently.
Electrical assembly must only be carried out by a qualified electrician!
Installation instructions
Fit the stand in accordance with the stand manufacturer's specification. In addition,
mount the second pedal.
Fit the motor on the table top.
Assemble table top and stand.
Connect treadle and motor lever.
Fit the transmission lever so that the centre hole is located underneath the hole for
the chain that is fixed on to the supporting plate.
Bolt the top section of the sewing machine on to the table top using two bolts. The
fleece must be laid between the top section of the sewing machine and the table top.
Connect the support plate chain to the transmission lever.
Using the long chain, connect the transmission lever to the second treadle.
Fit the V-belt and tension it using the hinged motor bracket.
Fit belt guard as shown in Fig. 11.
Fit the thread stand.
Fitting the finger guard (not on classes 220, 221, 271)
It is essential that the finger guard is fitted, to prevent any finger injury when opening the frame (with
treadle or stop motor).
To do this, remove the ratchet screw, bolt the finger guard onto the table top at a distance of approx
3mm from the supporting plate. Make sure that the supporting plate can move in front of the guard.
Refit the ratchet screw.
