Always refer yo your instruction booklet |  REPLACING FLEX OR SWITCH ON DCO4 Important: In the interests of personal safety, Qualtex do not recommend either the switch or the mains lead to be sold to the general public. They both require specialist knowledge and the use of a small leverage tool before either can be replaced. For engineers not familiar with the access procedure, the following tips may be useful.
1) At the time of writing, the special leverage tool to release the ON/OFF switch knob is not generally available. Qualtex therefore commissioned the manufacture of a suitable tool. This takes the form of a regulated size screwdriver, Part No: mis121. Bent at 90 degrees at a specific point along the blade length.
|  SWITCH TOOL 2) Referring to Sketch (A), there is adjacent to the ON/OFF knob, a small hole. If one inserts the screwdriver into this hole it only requires a little practise and careful leverage for the catch to be released, which locates the knob, and the knob can be lifted off. It is then a simple matter to replace either the switch or the mains lead.
3) Important: Treat the Switch Knob with care when releasing the catch as it easly broken |
