Safety instructions
• Arrange for defective power plugs and/or cables to be replaced at once by qualified technicians or our Customer Service Department.
• This appliance is not intended for use by indivi­duals (including children) with restricted physical, physio-logical or intellectual abilities or deficien­ces in experience and/or knowledge unless they are supervised by a person responsible for their safety or receive from this person instruction in how the appliance is to be used.
• Children should be supervised to ensure that they do not play with the appliance.
• Never use the machine when the ventilation apertures are blocked. Keep the ventilation apertures of the machine and the foot switch free from fluff, dust and waste material.
• Should the cable connected to the foot pedal become damaged, to avoid potential risks it must be replaced by the manufacturer, his customers services or a similarly qualified person.
Like any other electrical device, a sewing machine can cause serious, even life-threatening injuries. To avoid these, and to work safely:
• Always disconnect the power supply when leaving the machine unattended. This will prevent the risk of accidents if the machine is switched on accidentally.
• First pull the power plug before changing the bulb or performing maintenance work on the machine. This will prevent possibly life-threatening electric shocks.
• Do not pull the plug out of the wall socket by the lead. When pulling out the plug, always hold the plug, not the lead.
• Only use the sewing machine in dry rooms.
Warning about injuries and material damages:
• Keep your work space tidy. An untidy workplace can lead to accidents.
• Provide adequate lighting when working!
• Do not wear loose clothing or jewellery, as these can be caught in moving parts. You should also wear a hair net if you have long hair.
• Avoid adopting an unusual posture. Remain steady and in a well-balanced position at all times.
• If accidents occur as a result of handling the ma­chine with insufficient care, or failure to follow the safety instructions in this manual, then the manufacturer cannot accept liability.
• Never cover the ventilation slots! Risk of over­heating!

Place the overlock sewing machine on a stable and level surface. Ensure there is sufficient illumination at your workplace.
Adjusting the thread tree
Completely withdraw the thread tree 1 before threading. Turn the thread tree 1 so that the thread guides stand exactly above the spool supports 3.
Bobbin supports
Both industrial bobbins and household bobbins can be used with this machine. For industrial bobbins with a large diameter place the bobbins supports in with the broad end to the top, for bobbins with a small diameter place the support in with the narrow end to the top.

Bobbin caps
If using non-industrial thread bobbins, remove the bobbin supports and place the bobbin caps on the thread bobbins.
Connecting the foot pedal
Insert the plug of the footpedal g into the connection for the footpedal 5 and the power plug j into a mains power socket. To switch the machine on, press the power switch 7.
Attention!
During absences from the machine or when doing maintenance work, always remove the plug j from the mains power socket. Injury hazard!
Safety switch
This machine is fitted with a micro safety switch. You cannot start the machine if the front flap 8 is open. Close the front flap 8 before you start to sew.
Fitting the waste container
The waste container k collects remnants during sewing, so that your workplace stays tidy. Place the waste container k between the machine and the table.
Handwheel
Note:
Always turn the handwheel 6 towards yourself, that is, in the same direction as with a domestic sewing machine.
Controlling the sewing speed
The sewing speed is controlled by means of the footpedal h. The sewing speed is changed by ap­plying more or less pressure to the footpedal h.
Front flap
To open the front flap 8, slide it as far as possible to the right and, at the same time, draw it towards yourself.
