I've posted in the Festool Tool Problems board not because I've had this problem with a Kapex, nor even heard of anyone having this problem, but because this is a solution to a problem. Somebody might have this particular problem one day and come to this board, and the solution will be all ready and waiting for them! Matthew is very welcome to move this thread elsewhere.

On the UK Festool site there is Technical Note 10/08, dated 16 June 2008. It contains two photographs and the following text on how to sort a problem with the bevel setting zero point:

Tech Notes No. 10/08

Kapex bevel setting zero point "slip stop"

One of the more outstanding features of the new Kapex miter saw is the ease
of movement in setting a bevel angle. The tilting of the motor unit is spring
counterbalanced and a fine adjustment handle is located in the front.
Swinging to a new bevel angle has never been easier.
Festool is known for precision. It is one thing to build a machine that is
precise? it?s another to design a tool that REMAINS precise! You may have
noticed that when the position on the green bevel setting knob is set to "45-
0", it is possible to swing the saw over beyond the "0" stop.

When the saw body is moved rapidly toward this stop, it may pop past to the
right of the "0" position. Notice that the "0" stop point on the bevel scale
back plate is angled slightly. The tip of the post that indexes to this also has
an angled edge. This combination allows the spring loaded indexing post to
ride up and slip beyond the set point instead of breaking, or smashing into a
dead stop with such force that it disturbs the calibration. In the same spirit
as the slip clutch in the saw, it is a "slip stop".

When returning the bevel angle to "0", always use the fine adjustment rotary
handle to set it in position. And when setting a bevel angle over to the right
side, always place the green knob in the +-45 or +-47 position. To prevent
undue wear, avoid swinging the saw hard over to the right side when the
knob is set in the 0-45 condition.

Thanks for the note, I have just bought my 120 today and have been dissappointed the way it does not lock into 0', I dont fully understand your description of now to get it to lock into 90 degree mode,
I will have a play tomorrow to see if i can get it.....

Any more comments to detail the description some more?

Dan,
The "other brand" compact miter saws with which  I am familiar  have a hard detent at zero degrees bevel.  To some,  it feels good to "throw or slam" the saw back to that hard & fast detent.  It sounds and feels solid.  I've done it.  You know, a good solid thud. However, that hard jolt or slam is transmitted throughout the entire saw. 

The "slide stop" on the Kapex eliminates the effects of a "hard throw or slam" back to zero. 
 
Morning, ok i have read the instructions and had a play this morning at trying to get it to lock into the "0" position but no luck.

I have tried adjusting the flip lever in all manner of positions from full up to 45 to just above locking and in no position can i get a little feel of it locking home...
Your feedback is most helpful, thanks!

There is no detent you can feel, but when the lever on top of the saw is down, it is locked at whatever bevelsetting the saw is at when you put the lever down. So to lock it at 0° (or 90° depends on how you name the position) you put the green dial in the 0-45 position, and move the sawhead carefully untill it stops in the vertical position,(I use the turndial for this)  then lock the lever.
 
Ok time for the embarrassing bit, i found out what i was doing wrong.
I did not notice the little round dot on the blue lever that you lift up, this should correspond to the setting you wish to achieve.
I had the setting facing me where i could read it. Therefore 180' away from where it should be..doh
Now it makes perfect sense! lol

Thanks for all the help..

out of curiosity how many people do you think wind in the annoying allen screws to so you can pull the fence stops off?
Regards

Dan,

Glad you figured it out.  If you were asking about the those two tiny allen screws, my two were removed on the first day and stored away.  Personally I don't see the need for them.

Enjoy your new Kapex!
