4. Close tool by pulling the barrel back to
the semi-closed position. Never attempt
to close the tool by exerting force on the
front of the barrel. Never place your fingers
or hands over the muzzle end of the bar-
rel. The proper position of the hands and
fingers are shown in the illustration.
5. With the tool in the semi-closed position,
place it against the material to be fastened.
Hold the tool firmly at 90º with one hand and
completely depress, check to be sure the
groove on the barrel aligns with the marking
on the receiver.
6. Using a one pound hammer, strike the
firing pin button with a sharp, firm blow.
If the tool fails to fire, follow the misfire
procedure on page 5.
Note: It is important to strike the firing pin button
firmly and squarely. A light blow or one off-center
may not activate the load, however it will jar the
piston out of position which will cause a reduction in
power. (See Troubleshooting, page 10.)
7. To prepare for the next fastening, point the
tool in a safe direction, and slide the barrel
firmly forward. This action ejects the fired
load out of the tool and properly resets the
piston. The tool is now ready for the next
fastening.
