REPLACING THE FITTED PLUG (FOR UK ONLY)
Important
The mains lead for this machine is fitted with a standard (BS 1363) 13 amp plug and has a 13 amp fuse. When you change or examine the 
fuse, you must re-fit the correct 13 amp fuse. You then need to replace the fuse cover. If you have lost the fuse cover, do not use the plug until 
you have another fuse cover. 
Contact the people from you purchased the machine.
The 13 amp plug is the most widely used type in the UK and should be suitable. However, some buildings (mainly old ones) do not have 
normal 13 amp plug sockets. You need to buy a suitable plug adaptor. Do not remove the moulded plug.
Important warning: 
You must earth this machine.
The wires in the mains lead have the following color code:
• Green and Yellow: Earth
• Blue: Neutral
•Brown: Live
If the wires in the mains lead do not match the colors marked in your plug, do the following:
You must connect the green and yellow wire to the pin marked by the letter “E” or by the safety ‘Earth symbol’ or colored green and yellow or 
green.
You must connect the blue wire to the pin which is marked with the letter “N” or colored black.
You must connect the brown wire to the pin which is marked with the letter “L” or colored red.
You must have a 13 amp fuse in the plug, adaptor, or at the distribution board.
