The Tower Handbook
This section covers the sort of jobs that you can carry out with little or no specialist knowledge. Most routine maintenance includes a lot of common sense and what follows is intended as general guidelines to point you in the right direction.
A useful axiom quoted by a professional bellhanger
Your band may include professional engineers, fitters or others whose skills go beyond what we have assumed in this guide. They will be able to undertake more than we have described and their professional training should equip them to judge when they are working within the limits of their competence. Most laymen (and lay women) may be competent DIY people but are less aware of their limits. Do not attempt any maintenance if you are not certain of what you are doing. If you come across a problem we have not mentioned, or you are not sure about something, seek help and advice. In many cases we recommend you to seek advice anyway, since failure to do so may result in all sorts of problems. There are several sources of advice available to you. See section 14.12h about DIY limitations.
In this part of the Handbook there is a section for each part of an installation with simple explanations of what does what, the more common problems, how to prevent them and how to deal with them when something does go wrong.
