Re: power feeder on A3-31 - possible? - Added security?
Felder did not offer one with a riser in the back and David Best added a 6¡± riser on his Felder bracket to accommodate smart stand installation. Since I did not have any bracket, I designed one for my Dual51. Not that it is rocket science this Felder¡¯s bracket looks identical in basic design.
If anyone has any desire to go with a smart stand make sure that the riser is 6¡± back and 6¡±tall. This Felder bracket appears short (just from looking at proportions) on both dimensions.
Finally, I do not have A31 or A41 but from discussions here, the issue with models that are not prepped by Felder for PF installation is that there is not enough strong steel frame available on the back side.

They convey it wirelessly.? In the electrical panel that houses the start/stop switches, the wireless modules are located there. These modules relay yo the motor to start up when the switches are pushed.? There is a transmitter receiver behind the switches on the sliding table.? Under the blavk plastic handle/tray of the remote switche is a coverplate that houses the 9v battery needed to work the remote switches.
Hope this makes sense..haha

Re: CF 741 intermittent start
I had a problem starting the saw only on my CF 741.? All other functions worked.? The plugs that connect to the saw start and stop buttons came loose behind the panel.? So to trouble shoot there are interlock switches on the slide cover, the planer and planer hood.? These are connected in series to the e-stop and push button stops.? (why there is a mix of e-stops and push button stops is a German engineering mystery)? Push any one of these to drop out power to the magnet that holds a motor on function.? In my case, pushing the stop button on the saw when the planer was running did not stop the planer. This pointed to a bad connection at the saw start-stop button panel. ? Jon S ?

Re: CF 741 intermittent start
The only info I will add is that, from your description of blade cover MicroSwitch, your switch is working. It disables and enables, so both positions are providing whatever is necessary, electrically. So you should be able to adjust the position of the switch to make it work as intended. The screws on the MicroSwitch on the blade cover of K975 (diff cover) go in slots, so it can be moved fwd/backwards. Hopefully, yours is similar.

planer jointer table up
dust hood in planar mode
dust hood in jointer? mode
Is there any way of easily diagnosing which is at fault?

Re: CF 741 intermittent start
All the micro switches and stop buttons are wired together (NC normally closed), if you have a yellow light when in reverse, then the circuit is good. If the yellow light is on and it still wont start, then it could be the start buttons, they are all momentary switches (NO, normally open). All the switches on the machine can be effected by dust, some folks have had luck taking the covers off and blowing things out, some you just have to replace.
You can check them using a multimeter, but you have to get access to the wiring.

Re: K975 blade cover MicroSwitch
John,? The zci i made was another ¡°wing it¡± first to work out the design then make an improvements based on what I learned but haven¡¯t bothered as it just works. I did make a few extras. You are right it does screw up the flow when when a angle cut is needed, I usually just remove it and leave her wide open unless it¡¯s a lot of angle cuts then I will put the angled zci in. It really only takes likes 10sec to remove it. I actually have a few Ideas for a ¡°quick change¡± zci but I feel like I spend more time working on the shop than actually building anything, not a lot of time when I am already working 50hrs a week and even less in winter due to all things related to cold - firewood, snow, and I ski almost every weekend Nov - April I know first world problems...

Hi all
I am having issues with my CF 741 combination machine. It quite regularly goes dead and refuses to start.
The master switch which controls which part of the combo is functioning has a setting for reverse direction shaper. When you select this, a yellow light is illuminated so it offers an indirect way of finding out whether the machine is powered up. Mostly when I have the no start the yellow light comes on, this seems to indicate a safety microswitch issue. However I recently had an incident where the yellow light did not come on and I fiddled with the red mushroom switch on the jointer and it came good. You have to rotate this switch so that it pops out and I suspect mine may be a bit flaky, has anyone had problems with these? most of the time however I think the problems are due to the safety micro switches.
The microswitch on the saw blade cover is an issue, if I have a cover fully shut the saw won't start, I have to leave at about half an inch ajar. You can generally hear these switches clicking, is this clicking any indication that they are actually working electrically?
Is it the case that if any of the safety micro switches are not enabled for any part of the combo machine nothing will work? That is to say if a microswitch for the saw is indicating a problem then you can't start the jointer. If this is the case it does seem rather daft as it makes it really hard for the poor user to work out which micro switches are at fault. Is it safe to blow the microswitches? with air and is this likely to do any good?
I believe the CF 741 as the following micro switches:
saw blade cover open
planer jointer table down
planer jointer table up
dust hood in planar mode
dust hood in jointer? mode
Is there any way of easily diagnosing which is at fault?
thanks
Murray
