pull out the spring at the end of the gun. turn the staple gun upside down. Lay the staples in the track pointed side up, push in the spring slide so that it locks. You are ready to staple.

I have rebuilt many older Duofast staplers and have seen the problem that you describe. Duofast staplers have twice as many orings as other brands of nailers. Some people say that the nailers are over-engineered. I say that they were built to last a lifetime and need extra care when working on them. Duofast relies on various springs to reset functions or operations. For example there is a spring within the trigger valve that you do not see when you are rebuilding that may be weak and cant overcome the friction of the new orings. That spring resets the trigger after firing. If you replaced all the orings but did not replace any of the springs within the gun, it will take a while for the gun to get back to normal. I use new springs and lube all the parts with silicone lube instead of oil. Silicone lube is sold at Lowes in the plumbing department. It is used to lube orings in faucets. Instead of taking the gun apart, try using a little extra nailer oil in the gun and cycle the gun with-out nails dozens of times to work-in the new orings. If the problem does not go away, take a look at a breakdown and try streaching all the springs just a bit, or make sure that all the springs are in place. Also make sure that the head gasket is in good shape or the oring that seals the headvalve port to the body. Good Luck with your repair and email if you have other questions.
There should be a pusher that is attached to a spring. If the spring broke, or the pusher is missing the staples will not stay in place.
If you can locate a model number on the tool, you go to bostitch.com to find the parts you may need
SOURCE: stapler is not dispensing staples after new cartridge is inserted. Can you help?
Remove the staple cartridge, look into the cartrige area, are there any stray staples in this area, if so remove them, cycle the unit a couple of times without the cartrige in place, check the output end, any stray staples here? re assemble making sure you pull the first row ow staples even with the nozzle of the cartrige.
Hope this helps
