Safety instructions
EN
Electrical safety
• Only use the original power cord supplied with the sewing machine. Other power cords may damage the device. Do
not use the supplied power cord with other devices.
• Make sure that the mains voltage corresponds to the voltage indicated on the labelling of the device (devices labelled
230V or 240V can also be operated with 220V).
• The connection plug of the device must fit into the socket. The plug must not be modified in any way. Unmodified plugs
and matching sockets reduce the risk of electric shock.
• Avoid body contact with grounded surfaces such as pipes, heaters, cookers and refrigerators. There is an increased risk
of electric shock if your body is grounded.
• Keep the unit away from rain or wet conditions. The ingress of water into the device increases the risk of electric shock.
• Do not misuse the power cord to pull the plug out of the socket. When unplugging, grab the plug and not the power
cord.
• Keep the power cord away from heat, oil, sharp edges or moving parts of the device. Damaged or tangled power
cord increases the risk of electric shock.
Safety of persons
Careful handling and use of the device
• Be careful, pay attention to what you are doing and use common sense when working with the device. Do not use
the device when you are tired or under the influence of drugs, alcohol or medication. A moment of carelessness when
using the device can lead to serious injury.
• Avoid unintentional starting up. Make sure the device is switched off before connecting it to the power supply, picking it
up or carrying it. If you connect the device to the power supply when it is switched on, this can lead to accidents.
• Wear appropriate clothing. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from
moving parts. Loose clothing, jewelry or long hair can be caught by moving parts.
• Do not overload the device. Use the designated sewing machine for your sewing work. With a suitable sewing ma-
chine you will work better and safer in the specified power range.
• Do not use a device whose switch is defective. A device that can no longer be switched on or off is dangerous and
must be repaired.
• Never place anything on the foot controller.
• Unplug the device from the wall socket before making any adjustments to the device, changing accessories or putting
the device away. This precaution prevents the device from starting unintentionally.
• Keep the unused device out of the reach of children. Do not allow persons who are not familiar with the device or have
not read these instructions to use the device. Sewing machines are dangerous when used by inexperienced people.
• Maintain the device with care. Check whether moving parts of the device function properly and are not jammed,
whether parts are broken or damaged in such a way that the function of the device is impaired. Have damaged parts
repaired before using the device. Many accidents are caused by poorly maintained sewing machines.
DANGER! DANGER OF LIFE AND ACCIDENT FOR TODDLERS AND CHILDREN! Cleaning and user mainte-
nance must not be carried out by children without supervision.
• Use the device, accessories or insertion tools (e.g. needles, bobbins, etc.) according to these instructions. Take into
account the working conditions and the activity to be carried out. Use of the device for applications other than those for
which it is intended may lead to dangerous situations.

Safety instructions for service
• Have the device repaired only by qualified personnel and only with original spare parts. This ensures maintaining the
safety of the unit.
• If the LED lamp is damaged or defective, it must be replaced by the manufacturer or its customer services to avoid
hazards.
• The device may only be used with a specific foot controller and/or power cord in order to avoid hazards. If the foot
controller and/or power cord is damaged or defective, it must be replaced by the manufacturer, its customer services
or a similarly qualified person.
Safety instructions for all applications
• This sewing machine is to be used for sewing household textiles. Observe all warnings, instructions, illustrations and
data provided with the device. Failure to observe the following instructions may result in electric shock, fire and/or
serious injury.
• This device is not intended for processing other materials (e.g. leather, canvas, sailcloth and similar heavy fabrics).
Applications for which this device is not designed pose a risk; there is a danger of injury.
• Do not use any accessories that are not specifically intended and recommended for this device by the manufacturer.
Just because you can attach the accessory to your device does not guarantee safe use.
• Keep other people at a safe distance from your work area.
• Keep the power cord away from moving accessories.
General
• This device can be used by children aged from 8 years and above and persons with reduced physical, sensory or
mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning
use of the device in a safe way and understand the hazards involved. Children must not play with the device. Cleaning
and user maintenance shall not be made by children without supervision.
DANGER! DANGER OF LIFE AND ACCIDENTS FOR TODDLERS AND CHILDREN! Never leave children unat-
tended with the packaging material. The packaging material poses a choking hazard. Children often underestimate the
dangers. Always keep children away from the packaging material. This device is not a toy.
• Always disconnect the power plug before making any changes to the settings or changing accessories.
• Never operate the device if the ventilation openings are blocked. Keep the ventilation openings of the device and foot
controller free of lint, dust and fabric waste.
• Always turn off the device when performing adjustments or work in the area of the needle, such as threading or chang-
ing needle, threading or changing bobbin, changing the presser foot and so on.
Accessories
• Crown Technics GmbH can only guarantee the proper functioning of the device if the appropriate accessories are
used.
• Only use the original power cord supplied with the sewing machine. Other power cords may damage the device. Do
not use the supplied power cord with other devices.

• Always test thread and needle size on a small piece of fabric which will be used for actual sewing.
• Use the same thread for needle (upper thread) and bobbin (lower thread).
• Use the stabilizer material for fine or stretchy fabrics, and select the correct presser foot.
• The tension of the upper thread must be set at 2-3 when sewing the lightweight fabrics, like silk and jersey etc.
• Use the pins to fix the fabrics first before sewing two or more pieces of fabrics together.
