VALVE 9R201508

1. Disassembled by removing the cover
2. Saw the broken air in-let to the trigger
3. Replaced the trigger and actuator at the same time.
4. Ops checked good.
Note: The label says NO OIL on the rear in black on black plastic . I did NOT see that until I was taking it apart. I know why the o rings were bad! I o ... Read more iled the machine before I put it away last time I used it.

NOTES: The tubing in hard and you will need to gently heat it to shape it. You will need to heat it to remove it and install it. I don\'t have a heat gun so I used a lighter.
DO NOT USE OIL! This tool does not get oiled as other air tools. Oil, especially WD40, will rot the o-rings and degrade the plastic parts. That\'s why mine b ... Read more roke.
ALSO: if you\'re not good at remembering assembly and disassembly draw a diagram.

1. Remove the torx screws and split the two halves of the tool ( make sure the pin retainer o-ring doesn\'t fall and get lost) also make sure you note the position of the trigger safety spring
2.Remove the hoses from the valve and cylinder ( you will need to heat the ends)
3.pre-form the cylinder tube (use heat)
4. Attach the tubing to the nipples (Heat the ends) Take care not to stress the nipples the plastic is rigid and doesn\'t bend.
5. Reassemble and position the parts as per your diagram if you needed one.
6. The two halves may not mesh together. This is because you need to align the drive mechanism by using a thin screwdriver to push it into place.
6. Before you put the screws in make sure the slide to load the staples works properly.
Mine didn\'t and I had to loosen the screws back up and make sure it was free.
7. Now you\'re done. just put the screws back in and test it.

1. Open the stapler by removing the Torx screws and sliding the pivot pin for the main trigger out. Beware the rubber o-ring used to hold this in place, it will try to run away.
2. Drive the pin attaching the cylinder to the drive mechanism out, keep the clear plastic retainer.
3. Remove the cylinder by removing the large pin ... Read more from the closed end and disconnecting the hose.
4. Remove the valve by disconnecting the hoses.
5. Apply heat to the hose ends to make pushing them on easier and less likely to break off the nipples. Connect the valve and the cylinder
6. Position the cylinder, route the hose where it was when you opened the unit, push the large silver pin back to retain the cylinder in position.
7. Align the cylinder rod with the mechanism and slide the pin up to connect the cylinder to the drive mechanism, put the clear plastic ring around the pin to retain it.
8. Reassemble the unit with the Torx screws - pay close attention to aligning the drive mechanism in the slots before you close the shell and tighten.
9. Install the main trigger by positioning it in the stapler and pushing the pivot rod through, retain the rod with the small black o-ring that came off the unit when you took it apart.

Load with staples and test. My unit was a little sticky on reassembly, so I took it back apart and used molybdenum disulfide (MoS2) grease on the drive mechanism slots in the housing and reassembled. Works perfectly now.
