Problem with Tacwise 181EL Pro 230v Master Nailer

[mr_vampy]

I have had the above nailer for about 2 years, using it to pin mdf scotia beading onto skirting boards for laminate floors. When I was using it yesterday it suddenly stop firing the 15mm brad nails that I always use. I have checked for jammed nails, changed the fuse, etc, but it's not firing. Any ideas on what is wrong and if it is repairable? If is is not cost effective to repair, I shall purchase a new one.
Thanks

make sure you are not using left handed nails

Thanks, I have made certain I am using right handed nails.

Carefully open it up and check that the slidy bit you need to put pressure on has not misaligned itself. If it has then it won't trigger the microswitch and it will not fire even though it springs in and out correctly. I had this happen to me and it was just a case of resetting the position and it was as good as new.
