Hotpoint EW81 Halogen Double Oven Cooker. How to operate the ovens, the dials, auto flashing, setting the timer etc? All the general questions that would, or should appear it a "Operators Manual", NOT a service manual for safety reasons! Which in my opion should be available through the internet, or by post etc?
It is not absolutely clear if you are offering user guides for cookers - seeking user guides or just declaring that cooker guides should be, in your opinion, more freely available.
Part of the problem of course is the forced question mark in your title, however....
Several manuals for Hoitpoint stuff can be found here...
