7.5 Bringing the piston into the correct position
-NOTE-
The piston is incorrectly positioned when the nosepiece
of the tool has not extended to its original position after
the tool is lifted away from the work surface.
The piston can be returned to the correct position by
pressing the reset button. Nails can then be driven. In
exceptional cases, the tool may fire without driving a nail
when the tool is actuated for the first time after it has
been reset.
1. Press the reset button (the direction of movement is

on the gas can it should not be removed (except when
the can is disposed of). Place the gas can complete
with valve head in the toolbox.
