Just used the Plug-conversion kit above to convert three old Festo tools, will be doing the same with other tools from other brands. Most modern tools will be double-insulated and not have an earth connection (the Plug-it conversion cable as has been mentioned is only two core live and neutral). If the tool is metal cased and has an earth in the standard lead DO NOT CONVERT.
The pre-cut tails will need to be cut to the required length to suit the connector arrangement inside the tool and the to set the sheath at the appropriate length to ensure good clamping in order to prevent the inner cores being pulled.
The packaging lists the following as suitable for conversion : RS2, RS3, RS400/RS4, DS400, ES125, OF1000, OF900, ATF65, AT 65, AP55, AP65 and EHL 65.
The picture on the packaging shoes an RO150E with a conversion lead -go figure!
Let's say that you don't want to exceed the power requirements of any of the items Festool have actually listed on the packaging.
There is also the warning that repairs to electric power tools and electrical components may only be carried out by trained electricians.
A few advantages - tools now fit easily into their respective boxes no need to slam shut lids as the ccoiled cable tries to jump out at you or fould on the case as you close the lid. Some cases it is obvious that the only time the cables would fit properly is when the tool was initially packaged with all the cable ties and other packaging. You can keep say two good condition leads (one short, one long) rather than whatever happens to be on the tool and safety - very easy to isolate power totally (and see that it is isolated) when changing bits/attachments, the easier it is the more likely you are to do it. Also the obvous point that you can change tools where you are working and not have a multiplugs/adapaters/extension leads everywhere.
