Safety instructions

Like any other electrical device, a overlock

machine can cause serious, even

life-threatening injuries.To avoid this, and in

order to work safely:

• Before initial use of your overlock machine,

read these operating instructions thoroughly.

• Keep the operating instructions in a suitable

place near the machine. When passing the

appliance on to others, always enclose the

operating instructions.

• 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 remove the plug from the socket by

pulling on the cable. Always grip the plug and

not the cable when pulling out the power

plug.

• Only use the overlock machine in dry rooms.

• In case of any visible damage on the

machine, the foot switch or the power cable:

again.

• Never let children or elderly persons handle

the machine unsupervised because they may

not properly appreciate the possible dangers.
