REASSEMBLING THE Stapler:
1. Be sure the Rubber Seat, Support Ring and Cylinder
are installed in the Body and are facing the correct way.
2. All seal surfaces must be clean and lubricated
generously with Pneumatic Light Air Tool Oil lubricant.
Replace any part that shows signs of wear.
3. Use care when installing the seals into their respective
cavities. Be sure the Seals are contained in their
groove and do not come out as the parts slide together.
Generous cavity lead in chamfers have been provided to
help Seal installation.
4. Carefully insert the Piston Rod into the return Cylinder
and screw the Piston onto the rod. Be sure the Piston is
facing the correct way, ears up, hex down.
5. Assemble the Driving Blade, Dowel Pin and Jam Nut
on to the Piston Rod.

of the Stapler Body Cylinder.
7. Be sure there is a new O-Ring Gasket in the top
groove of the Return Cylinder.
8. Insert the Plunger into the top cavity of the Body.
Line up the holes and install the three Plunger retaining
screws. It is important that the three #10-32 screws are
tight or air leakage will occur. Our recommendation is to
use 1-2 drops of blue Loctite® or similar on the 3 screws.
9. Position the Safety Yoke in the Plunger groove.
10. Install the Body Cap and Plunger Rubber Cap.
11. Turn the Stapler upside down. Install the Rubber
Bumper, Staple Channel Assembly and Adapter Foot. Be
sure to align up the Driving Blade with the slot in the Foot
before the Stapler is closed up.
12. NEVER FIRE THE Stapler WITHOUT THE RUBBER
BUMPER INSTALLED, IT WILL DAMAGE THE Stapler.
TO CLEAR A Staple JAM:
1. It helps to tap the Driving Blade back to the retracted
position before trying to remove a jammed staple. A
spare Driving Blade works best for this.
2. Try to pull the jammed staple out of the gate with a
pair of long nose pliers. If this does not work remove the
four (4) cap screws holding the Foot, Gate and Staple
Channel Assembly together.
3. Separate the Foot and gate with a screw driver just
enough to clear out the jammed staple.
4. Put thread locking compound on all screws and
reassemble the components.
