Only used for casual domestic DIY. Recently it's become difficult to start. It is not the electricity supply. I depress the on switch and nothing happens, but if I shake it a little while holding switch on it starts. The problem is intermitant at the moment.
I guess its just coming to the end of its useful life... what say you!
Just to clarify, the plastic flat headed caps behind which the brushes live are located about half way along the body of the machine, 180 degrees apart from each other. They'll be about the size of a 1 cent coin in diameter.
The brushes are square/rectangular section lengths of carbon. If square they can go back one of four ways, if rectangular then two. it's important that you put the back the exact same way you took them out and don't mix up the sides you took them from (they've been worn into a particular shape). Consider giving the holes from which you've extracted them a blow out as well. Don't go too mad on stretching the springs.
As suggested, the power cable itself might be dodgy - although a loose connect/break in cable would tend to give you stop/start problems during use, not just at start up
