I purchased this machine few months back. Microcom 9009 table top.
The seller, not a framer, hooked it up to compressor and seemed to work fine. I move it to my new workspace and now it won't fire nails.

It does:-
-Engage rabbet clamp when foot pedal is depressed.
-When I engage button/handle firing handle, moulding clamp comes down and that's it. I can release mounding clamp only with red spring release on other side.
The firing activation mechanism seems to be a 2 -step. It has a plastic disc with bevelled edge and has 1 action when moved back & forth and a 2nd when button fired. With me, the back or forth motion causes moulding clamp to come down.

Any help will be much appreciated.
 
I have this underpinner or a version of it but I don't understand this bit ..

Mine has a red button on the side and you cannot operate the main trigger without this depressed - a safety feature, is that what you mean?

If the moulding clamp (pressure pad) goes down but does not return, it's usually lack of pressure or due to the hammer being stuck up.
 
RoboFramer - thanks so much for the response.

-What pressure do you have your compressor set at?
-The right safety red button on mine is bypassed? I don't see any air lines or wires going to it.
-The red trigger handle seems to have 2 steps?
Could you possible just run me through the operating sequence you use.
thanks.
 
My compressor cuts out at 10 bar (I've no idea what that is in PSI) but the underpinner has a regulator with an 8 bar max - about 1 or 2 o'clock on its dial, the dial you can see on your photo, the compressor kicks in when that dial is at about 11 o'clock. That pressure can be adjusted by pulling out the gray knob below the dial and turning it.

If you have no air lines going to your red safety button (there won't be any wires, it's a totally air-operated machine), it's not doing anything. Can you operate the machine without it depressed?

The red safety button also locks the movement, handy for stacking.
 
My air pressure is at 120 PSI. I will try abit higher.
The red safety button doesn't do anything.
When I depress the foot pedal, the moulding clamp engages.
When I depress the nailer button, the moulding hold down comes down and that's all it will do.
 
I think your problem is that your return spring is broken. Try turning it on it's side and you should see two springs. One or both may be broken.Replace both, they aren't expensive. You can buy these and any other parts you may need here: http://www.ledsome.com/ Don't turn up the pressure! I suggest you turn it down to around 80psi /100psi tops. This is a great machine, build like a tank and will last forever if taken care of. Make sure you put a air dryer/oiler on it, to keep the cylinder clean! I've had one of these for years, let me know if you need any more help.
 
Jerry, thanks for the input.
Could you please tell me the sequence of normal operation.
-Does foot pedal only engage rabbet clamp? does it need to be depressed to fire nails?
-The firing button seems to have 2 step functions
-Does yours have a safety button?

I will check out the springs. Mine does however have a small red button near the shaft for the downward clamp that the releases the clamp if I depress it.

Yes, it looks like great machine. Mine is in excellent condition. I'm just a little frustrated, because it seemed to work fine when i picked it up, but now has a problem after being moved.
I checked all the hoses and none seemed loose.
 
Does foot pedal only engage rabbet clamp? Yes

does it need to be depressed to fire nails?
I think so, I've never tried to nail anything with out it engaged.

-The firing button seems to have 2 step functions
-Does yours have a safety button?
Yes the safety button is on the left near the front. You must press and hold it while pressing the firing button.

If you don't have the manual you'll find it here:

I really can't add much to the tips already given but I had a 9009 that I bought new in 1988 and I used it exclusively for over 20 years with no problems or broken parts whatsoever. It indeed was built like a tank and never let me down one time in all those years. I suspect they incorporated some safety stuff on the newer models as I don't remember a red safety button that had to be pushed to fire the v-nails, mine fired them as soon as I pushed the round ball down on the positioning handle. I replaced the shorter tables with the extended tables so I could handle wider mouldings but that is the only thing I had to buy for the machine besides v-nails and one air line coupler.

I had no idea that there were still parts available for those older machines. I sold mine to my last boss in 2008 when I left her employ and I understand that something broke on that one about a year after that time. I may try to buy it back from her if I can figure out what is wrong and find the parts to fix it. We need one in the shop where I am working now and I would get another 9009 in a heart beat or fix up my old one if possible. I have used a couple of different models of AMP and one pistorius v-nailer and none of them came anywhere close to performing like that 9009 did on its worst day!!
 
Tom,
I bought my 9009 new also. I bought a fletcher 5700 about a year ago from a shop that was closing down, and haven't used my 9009 for several months. I still have everything that came with it including the original shipping case. It's in great shape and has the extented table also. I'll be happy to sell it to you for $950.00 . PM me if your interested.
 
Larry, thanks.
I just discovered your "manuals" page. What a great resource.
I will let you know if I can find one.
