If y o u don't have an instruction manual you can probably download a copy from casesses website, I had a jammed nail last week (casesse 1) and it was very easy to remove the block once I had the instructions.

Thought I had replied to this yesterday but obviously didn't posr it.

What you need to do is remove the block. There should be s small Alan key screw on the side of it to remove it. Yhe block should lift out. Once it is out there are 4 more alan key screws which will release the block in half thus allowing you to clear the blockage. When you have done this put it back together applying a tiny amount of grease to the inside of the bock first. Once you have done this you need to slot the block back over the hammer pin. It's worth checking the hammer pin for damage as well they can split. Once you get the block back in place level it off with the base plate and tighten up the Alan screw. Jobs a good un .

I had this issue in a CS88.
Every so often one would jam and I had to do what Grays describes.
In the end I had to get a new firing pin as it was buckled.

I have jamming problems if I use 15mm wedges. If I stick to 10mm, no problems as all. It seems there are issues with 15mm wedges, so if it's happening a lot, it might be worth ditching them.

This is true! Cassesse 15mm wedge cartridges are often a problem to use on the Cassesse manual machines, but not on the Cassesse pneumatic machines which have a larger and therefore stronger wedge magazine feed spring. Having said that my first Cassesse machine was a CS-79 and that never had any problem with 15mm wedges, so maybe not everyone has the same problem. Both machines I have had since then were CS-88's and particularly the latest one does not like the Cassesse wedges in the Cassesse cartridges at all.

Part of the problem may have something to do with the fact that the Cassesse 15mm and 12mm wedges have a horizontal indent pressed into the wedges at about have way up, but also that the smaller wedge magazine feed spring has difficulty overcoming the extra friction inside the cartridges when the cartridges are loaded with these larger wedges and therefore have a greater area for creating friction, or drag opposing the spring pushing the wedges fully forward.

I have managed to overcome this problem by reloading old empty cartridges with the alphamacchine "power twist" universal wedges. These are glued together in sticks which are easy to handle and to lubricate with petroleum jelly before inserting into the cartridges. Cassesse do warn users not to use any wedges other than Cassesse wedges and say that this could void the warrantee on your machine. Well, I do it anyway and I've been doing it for a long time now without the slightest problem, so what the heck!

I like the power twist wedges and think that they pull the mitres together very well, but others think that the cassesse wedge are good to. So you pay's yer money and takes your choice!

BTW, I had some 7mm Inmes wedges which I tried in the machine and they tended to jam in the machine, so not all universal wedges are neccessarily suitable for reloading Cassesse cartridges, although I can't identify what the difference between different manufacturers wedges might be.
