A model number and decent picture might help someone identify it, diynot.com is a good place to ask about this kind of thing they are tool freaks on there. The levers actually look like lift to release clamps, is there a spline under them?
Are they clamping down some kind of sliding arrangement that disappears under the guard on top - right and left fences maybe? Can you see what moves when you fiddle with them? Graham.
Honestly not too sure, pics pinched off internet,
dewalt 1150
not sure if the machine had any optional accesories -- say- possibly slot mortice?? attachment
On your pic, thought they were for the crown guard, (the top one) but I see its on the other side,
extractor hood during thicknessing?? or a separate crown guard when tables are in the thicknessing position.( if you dont have a hood?
they dont hold the fence in place??
I`ll have a wee try and a look about see if I can find out
(wood Machinest)
im thinking that they are there just to attach things to like the side guard/guide on the picture above,, or like u say with the other things,,
they dont seem to do anything when slackend right off,
I have an old (but mint cond.) floor standing Elu similar to that!
The turn-screws are for clamping down optional accessories. Dewalt, who took over from Elu, still use the same fixings today and I have these on several of my bigger Dewalt tools. As a matter of fact, the green livery on your Dewalt, is as much Elu's, as part of Dewalts' brand is yellow.
There is lots of good documentation on Dewalt (&Elu) machines. All you need is a model number and go to Dewalts website >service section for the schematics.
IMO;
The one on the left (1st pic) is probably for holding on a auto-retractable planner blade guard.
The second fixing on right (1st pic) is for a sliding fence.
