Loading Nails or Staples

1.   Depress the Click Lever (#49) and pull back on the Tail Cover (#53).
2.  Insert the brad nails into the Magazine, letting the pointed end ride on the rail of
Magazine A (#45). If loading staples, fit the crown of the staples so they fit over, and ride on
the rail of the Magazine A (#45).
3.  After the nails or staples reach the nose of the tool, close the Tail Cover (#53).

Testing The Contact Safety Trip Mechanism
1.  The Stapler/Nailer should not fire if the nose is not depressed against the workpiece.  This
tool has a contact safety tip mechanism, which is designed to prevent inadvertant firing.  The
tool will only fire if the Safety (#37) is resting on the workpiece prior to pulling the
Trigger (#30).
2.  Make sure the tool is disconnected from the power supply.
3.  Empty the magazine of nails or staples.
4.  Check that the Trigger (#30) and the Safety (#37) on the nose of the tool, move freely,
without sticking.
5.  Connect the air supply to the tool at the Air Plug (#58) and set at the recommended 60
PSI, and not over the maximum 100 PSI.
6.  Test the tool by depressing the Safety (#37) on the nose of the tool against the workpiece
without pulling the Trigger (#30) The tool must not cycle (fire).  If it cycles (fires), stop
immediately and take the tool to an authorized service technician for repair.
7.  Hold the tool away, or off of the workpiece.  The Safety (#37) or nose of the tool should
return to its original position.  Squeeze the Trigger (#30).  The tool should not cycle (fire).
If it cycles (fires), stop immediately and take the tool to an authorized service technician.
8.  Depress the Safety (#37) on the nose of the tool against the workpiece and squeeze the
Trigger (#30).  The tool must cycle (fire).  If it fails to cycle (fire), take it to an authorized
service technician.

Operating the Stapler/Nailer
1.  Attach the Nailer/Stapler to the air supply at the Air Plug (#58).  Start your compressor and
check the pressure making sure it is set at the recommended 60 PSI and not over the
maximum 100 PSI.
2.  To fire, place the nose of the Nailer/Stapler on the workpiece.  The Nailer/Stapler should
not fire if the nose is not depressed.  Once depressed, gently squeeze the Trigger (#30)
once.  Do not fire repeatedly;  nails or staples could bounce off of one another, causing injury.

Clearing Jams
1.  Disconnect tool from air hose.
2.  If a nail or staple is jammed in the discharge area, simply remove it with pliers.
3.  If a nail or staple is jammed in the magazine, depress the Click Lever (#49) and pull back
on the Tail Cover (#53).  Remove the jammed fastener and close the Tail Cover (#53).

Operation (continued)

Warning!  After disconnecting the Nailer/Stapler from the compressor, there could still
be enough air pressure to fire the Nailer/Stapler.  Aim the Nailer/Stapler into a piece of
scrap, and fire until all of the pressure releases.

Note: The window gauge on Magazine A (#45) lets you know how many nails or staples
remain.
