I have a Fedders Window Air conditioner, model A2008F2BG. It was working great until today. Now it comes on but the fan wont blow much air. Any ideas?


I believe that is an older window unit. I don't know how difficult it is to get to the fan, but I would check to see if it can be cleaned, then see if there is any insulation or anything that is blocking air flow. I am assuming the filter is clean?

Pneumatic stapler trigger stuck


The click sound indicates that the headvalve opened to fire piston down the barrel, however piston is already down or is stuck in-place. If the piston/driver is not broken or stuck, push piston to top of cylinder to reset. If only one shot and piston stays down, most likely the check band is broken. Check band is on the outside of cylinder (lower part) is is usually an oring or band of rubber covering small holes drilled into cylinder. Check valve /band is what causes the piston to return to top. If check band is good, most likely piston is bent or oring is too tight. If you open the gun, lube all parts with white grease or silicone paste lube. Good luck

Only shoots out one nail for every 4 or 5 trigger pulls


The gun will miss fire if the driver does not return to top position allowing nails to move into position. Could be bent driver, faulty trigger, cracked lower bumper or check valve not in place. Easy to check if trigger. Remove air supply, and remove the pin holding the trigger. Fire the nailer by depressing the firing pin with your finger. If the gun works ok, single fire trigger is faulty or safety foot is out of adjustment. If still miss fire, remove head and pull out cylinder and piston. Check for bent driver, cracked lower bumper or black band (check valve) is out of place on outer part of cylinder covering a row of holes.

Bostitch N60 finish nailer. The driver will not return. into gun and blows air out by trigger. How to fix?


You will need to replace the trigger valve, the one you need is a P/N- TVA6. As far as the driver not returning, it could be a broken head valve spring,(spring in the back cap under the head valve) or possibly a broken driver blade.

Piston drives down when hooked up to air...piston does not return up. is this a problem with the triger valve? I am not pulling the triger, just hooking up the air. This gun hasnt been used in 10 years,...


Sounds like the head valve is stuck in the head. Take black head off and see if the valve is spring loaded by pushing down and see if it comes up. This is the usual problem.

No brad


Your anvil is not returning to the home position to allow the brad to index into the receiver. Try and push the anvil up all the way to the home position. If that works, then you need lubrication, new return spring, etc. All related to the anvil firing.

When pulling trigger air blows but does not fire


This problem can happen because of several reasons.
Most likely the driver stuck, and not able to move.

First with the tool disconnected from the air supply check to see if there any nails jammed in the nose piece.

If the driver is stuck down, try to push it up. Will it move?

If there are no problems visible at this point you will have to open the tool up, and see if anything looks out of place.

To examine the inside of the tool, unscrew the 4 bolts on the cap of the tool. Gently remove the cap, it may be spring loaded but once the bolts are loosened, there is no reason to be afraid of the parts springing out. Be careful not to let the parts that are in the head cap fall out. Also take care not to rip the gasket. Keep in mind, the less parts inside that you disturb the better so be careful.

If the piston driver does move. Does it move freely?

Sometimes when a driver hits a very hard knot in the wood, or if a nail is hit. The thin driver may bend. If it is moving but with resistance. Use a thin object to push the driver upward from the nose. It will come out of the head cap end.

Check to see if the driver is straight and square to the piston. If it is bent, you may need to replace it. Sometimes you may be able to bend it back enough to allow the piston driver to move freely.

If this solves your problem. To reassemble:

Replace the driver in the correct position. Replace the gasket if it is loose. If parts came out of the head cap, reposition them into the cap. Replace the head cap on to the tool. Replace the bolts, stagger as you tighten them to depress spring loaded parts evenly.

Hook the tool up to your air supply check for air leaks, and fire the tool.


If the driver does not move: Examine to see what is seizing the piston and reply back.

I hope this works!

I had the same issue with an older craftsman 351-18309 brad nailer and crown stapler. When I pulled off the top of the piston, there was a denigrated o-ring. I took an ear bud for my Bluetooth headset, cut it to size and stretched it to prevent it from holding the spring... And I'll be damned it worked! It both tools!!
